Description
These JDSU SFPs are integrated fiber optic transceivers that provide a high-speed serial link at a signaling rate up to 4.25 Gb/s. They conform to the
American National Standards Institute’s (ANSI)
Fibre Channel, and SFF-8472 specifications.
The JSH-42L3AD3-5 supports a maximum fiber distance of 5 km and is available with blue color identification or gray color identificaiton (JSH-42L3AD35G). The JSH-42L3AD3-20 supports a maximum
fiber distance of 20 km. These transceivers operate
on singlemode fiber only.
The transceiver is ideally suited for Fibre Channel
applications which include point to point links as well
as Fibre Channel Arbitrated Loop (FC-AL). It can
also be used for other serial applications where high
data rates are required. This specification applies to
a hot-pluggable (SFP) module which is an electrical
surface-mount connector assembly.
The transceiver features a microprocessor with
imbedded non-volatile RAM. Vital product data is
stored in the NVRAM and several optical and electri-
cal characteristics of the transceiver are computed
“Real-Time” with the results written to memory. This
data can all be accessed by a two-wire serial interface at the SFP connector.
Encoded (8B/10B) [3], [4], serial differential signals
traverse the connector interfacing the transceiver to
the host card. The serial data modulates the laser
and is sent out over the outgoing fiber of a duplex
cable.
The transceiver is a certified Class 1 laser safe
product. The optical power levels, under normal
operation, are at eye safe levels. Optical fiber cables
can be connected and disconnected without shutting
off the laser transmitter.
The transceiver is also compliant with the RoHS
Directive from the European Union - Directive
2002/95/EC on the Restriction Of use of certain
Hazardous Substances. The largest change with
optical transceivers comes with the removal of all
lead-based parts and soldering. Now it is a lead-free
part.

Laser Safety Compliance
The JDSU transceiver is a CLASS 1 LASER PRODUCT as defined by the international standard IEC
60825-1, Am.2 (2001). The product also complies
with U.S.A. regulations for Class 1 products contained in 21 CFR 1040.10 and 1040.11. Laser emissions from Class 1 laser products are not
considered hazardous when operated according to
product specifications. Operating the product with a
power supply voltage exceeding 5.0 volts may compromise the reliability of the product, and could
result in laser emissions exceeding Class 1 limits
identified in IEC 60825-1, Am.2 (2001); under these
circumstances, viewing the transmitter port with optical aides (i.e., eye loupes) should be avoided.
ESD Notice
It is advised that normal static precautions be taken
in the handling and assembly of the transceiver to
prevent damage and/or degradation which may be
introduced by electrostatic discharge.

LW 4x/2x/1x FC SFP with DDM
Transmit Section
The input, an AC coupled differential data stream from the host, enters the AC Modulation section of the laser
driver circuitry where it modulates the output optical intensity of a semiconductor laser. The DC Drive circuit
incorporates an automatic power control (APC) loop which maintains the laser at the correct preset power
level. In addition, safety circuits in the DC Drive will shut off the laser, or guarantee safe launch power if a
fault is detected. The transceiver provides the AC coupling for the +Tx/-Tx lines. No AC coupling capacitors
are required on the host card for proper operation. There are two outputs from the transmitter section that
deliver signals proportional to the average transmitted optical power and also the laser average bias current.
These signals are digitized and processed within the transceiver for the Digital Diagnostic Monitoring feature.
Receive Section
The incoming modulated optical signal is converted to an electrical signal by the photoreceiver. This electrical
signal is then amplified and converted to a differential serial output data stream and delivered to the host. A
signal strength detector indicates whether light is present or not at the input to the photoreceiver. This signal
is provided to the host as a loss-of-signal (Rx_LOS) status line. The transceiver provides the AC coupling for
the +Rx/-Rx lines. No AC coupling capacitors are required on the host card for proper operation. There is an
output from the pre-amplifier in the photoreceiver that is proportional to the average optical power incident on
the photodiode. This signal is digitized and processed within the transceiver as part of the Digital Diagnostic
Monitoring feature.
Digital Diagnostic Monitoring
The digital diagnostic monitoring feature is compliant with document SFF-8472, “Digital Diagnostic Monitoring
Interface for Optical Transceivers” [5]. In addition to transmitted optical power, laser-bias current and received
optical power, there are also sensors for transceiver temperature and supply voltage which are all multiplexed
to the analog-to-digital converter. After the signals are digitized, they are processed and compared to alarm
levels for the optional alarm features and interrupts. The real-time values of each monitored parameter can
be read and used for evaluating the status of the link. Also, the alarm/warning bits can be used to provide
transceiver status or enable an interrupt notification. A user-writable non-volatile RAM scratch space for customer use is limited to 100,000 write cycles.
Optional Monitor TX_FAULT Alarm/Warning Interrupt
The transceiver provides programmable Alarm/Warning Interrupt Enable bits. They are used by the transceiver to generate a TX_FAULT signal usable as an interrupt to the host for an alarm/warning condition. This
is an extension to the polling architecture of SFF-8472 and allows for interrupt driven host microcode. For a
complete description see section “Vendor Specific Digital Diagnostic Monitor TX_FAULT Alarm/Warning
Interrupt” on page 37.

Input Signal Definitions
Levels for the signals described in this section are listed in Transmit Signal Interface on page 16 and Control
Electrical Interface on page 17.
Tx_DAT
A differential serial data stream is presented to the transceiver for transmission onto an optical fiber by modulating the optical output intensity of the laser.
Tx_Disable
When high (logic one), the Tx_Disable signal turns off the power to both the AC and DC laser driver circuits.
It will also reset a laser fault if one should happen. When low (logic zero), the laser will be turned on within
1ms unless a Tx_Fault condition exists.
When this signal is asserted, the laser monitoring function will report low power and low bias current. The
alarm/warning flags for these quantities will also become active. Additionally, the Tx_Disable indicator, bit 7 in
byte 110 of the DDM page will become active. See Monitor Data Table 4 on page 35.

Output Signal Definitions
Levels for the signals described in this section are listed in Receive Signal Interface (from transceiver to host)
on page 17 and Control Electrical Interface on page 17.
Rx_DAT
The incoming optical signal is converted and repowered as a differential serial data stream. The Receive Signal Interface (from transceiver to host) table on page 17 gives the voltage levels and timing characteristics for
the Rx_DAT signals.
Rx_LOS
The Receive Loss of Signal line is high (logic one) when the incoming modulated light intensity is below that
required to guarantee the correct operation of the link. Normally, this only occurs when either the link is
unplugged or the companion transceiver is turned off. This signal is normally used by the system for diagnostic purposes.
This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.
The recommended value for this resistor is 10 kΩ.
Tx_Fault
Upon sensing an improper power level in the laser or any other potentially unsafe condition, the SFF sets this
signal high and turns off the laser. The Tx_Fault signal can be reset with the Tx_Disable line.
The laser is turned off within 100 μs as shown in the Transmitter Fault Detection timing diagram below.
This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.
The recommended value for this resistor is 10 kΩ.
Tx_Fault can also become active if the alarm/warning enable control bits are set within the 0xA2page. For a
complete description see section “Vendor Specific Digital Diagnostic Monitor TX_FAULT Alarm/Warning
Interrupt” on page 37.

MOD_DEF(0:2)
A two-wire serial interface is used to access two 256-byte memory spaces that describe some of the capabilities, standard interfaces, manufacturer, optical monitor levels, alarms and other information relevant to the
product. Some of this space is protected and some is user writable. Also some of the space is non-volatile so
that information is retained during unpowered conditions. Tables describing the specific addresses and values of the memory space are included in Two-Wire Interface Timing Specifications on page 23 and on page
31. Operation of the two-wire interface is described in Two-Wire Protocol for Serial ID and Digital Diagnostic
Monitoring Information on page 11. Signal timings necessary for proper operation of the Serial ID function are
shown in Two-Wire Interface Timing Specifications on page 23.
The two-wire interface requires both a serial clock (SCL) and serial data I/O (SDA) connections. These signals are required to have pull up resistors on the host board to the 3.3V supplying the transceiver (4.7 kΩ is
the recommended value; however, a smaller value may be needed in order to meet the Serial ID’s rise and
fall time requirements). The following list and figure show the necessary connections from an interface to a
SFF to ensure the capability of reading the Serial ID data.
MOD_DEF(0): Logic Low

The serial clock (SCL) and the serial data (SDA) lines appear as NC to the host system upon initial power up.

Two-Wire Protocol for Serial ID and Digital Diagnostic Monitoring Information
Product specific information is stored in the device and is accessible via a standard two-wire interface. Some
of the data is non-volatile and some is updated real time with data that characterizes critical conditions of the
transceiver. While most registers are read only, some registers can be written by the customer for use as
scratch space or to set interrupt enables or clear interrupt indicators.
There are two data addresses which can be used to access two different sets of data. The page address
0b1010000X is used for the set of Serial ID data and the page address 0b1010001X is used for the set of Digital Diagnostic Monitoring information.
Critical timings for communicating to the module on the two-wire interface are shown in Two-Wire Interface
Figure 8 on page 14. For more information on the Serial ID protocol, see Two-Wire Interface Timing Specifications on page 23.
Two-wire Data Read
To read data from the device, the following sequence must occur on the Two-wire interface (refer to TwoWire Interface Figure 2 on page 13, Two-Wire Interface Figure 3 on page 13, and Two-Wire Interface Figure
4 on page 13 throughout these steps):
1. Send a start signal to the module.
A start signal is presented by toggling the data line from high to low while the clock is high (see Two-Wire
Interface Figure 2 on page 13).
2. Send the write data sequence.
The write data sequence consists of the bits 0b10100000 for the Serial ID data or 0b10100010 for the
Digital Diagnostic Monitoring information.
3. Receive an acknowledge signal.
One zero bit is the acknowledge signal.
Once this sequence has been acknowledged, the user will send the memory address to start reading
from.
4. Send the address of the first byte to be read during the subsequent sequence.
5. Receive an acknowledge signal.
6. Send a start signal.
7. Send the read data sequence.
The read data sequence consists of the bits 0b10100001 for the Serial ID data or 0b10100011 for the
Digital Diagnostic Monitoring information.
8. Receive an acknowledge signal.
Once this sequence has acknowledged, the user will begin receiving data bytes.
9. Receive a data byte.
10. Send an acknowledge signal to receive the next, consecutive data byte, or send a no-acknowledge signal
followed by a stop signal to stop receiving data.
A stop signal is presented by toggling the data line from low to high while the clock is high (see Two-Wire
Interface Figure 2 on page 13).

Two-wire Data Write
To write data to the Digital Diagnostic Monitoring data address of the device (writes are not allowed to the
Serial ID data address), the following sequence must occur on the Two-wire interface (refer to Two-Wire
Interface Figure 1 on page 13, Two-Wire Interface Figure 2 on page 13, and Two-Wire Interface Figure 3 on
page 13 throughout these steps):
1. Send a start signal to the module.
A start signal is presented by toggling the data line from high to low while the clock is high (see Two-Wire
Interface Figure 2 on page 13).
2. Send the data write sequence.
The write data sequence consists of the bits 0b10100000 for the Serial ID data or 0b10100010 for the
Digital Diagnostic Monitoring information.
3. Receive an acknowledge signal.
One zero bit is the acknowledge signal.
4. Send the address of the first byte to be written during the subsequent sequence.
Valid byte addresses are 0b01101110 for one byte, and byte addresses 0b10000000 thorough
0b11110111.
5. Receive an acknowledge signal.
6. Send a data byte.
7. Receive an acknowledge signal.
8. Send the next, consecutive data byte (reference Two-Wire Interface Figure 7 on page 14), or send a stop
signal to stop sending data (reference Two-Wire Interface Figure 6 on page 14).
A stop signal is presented by toggling the data line from low to high while the clock is high (see Two-Wire
Interface Figure 2 on page 13).

1. The minimum and maximum values of the average received power in dBm give the input power range to maintain a
BER < 10-12 when the data is sampled in the center of the receiver eye. These values take into account power penalties caused by
the use of a laser transmitter with a worst-case combination of spectral width, extinction ratio and pulse shape characteristics.
2. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero.
The Optical Modulation Amplitude is defined in terms of average optical power (PAVG in μW) and extinction ratio (ER) as given by
OMA=2PAVG((ER-1)/(ER+1)). The extinction ratio, defined as the ratio of the average optical power (in μW) in a logic level one to
the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unit less linear) ratio and not expressed in dB. For example, the specified OMA at 4.25 Gb/s is equivalent to an average power of -17.3 dBm at an ER of 9 dB. At 1.0625 Gb/s and 2.125 Gb/s, the specified OMA is equivalent to an
average power of -20.2 dBm at an ER of 9 dB. Typical values below the minimum specification indicate margin beyond the specification.
3. The Rx_LOS has hysteresis to minimize “chatter” on the output line. In principle, hysteresis alone does not guarantee chatter-free
operation. The transceiver, however, presents an Rx_LOS line without chatter, where chatter is defined as a transient response
having a voltage level of greater than 0.5 volts (in the case of going from the negate level to the assert level) and of any duration
that can be sensed by the host logic.

1. Launched optical power is measured at the end of a two meter section of a singlemode fiber. The maximum and minimum of the allowed range of
average transmitter power coupled into the fiber are worst case values to account for manufacturing variances, drift due to temperature variations,
and aging effects. The minimum launched optical power specified assumes an infinite extinction ratio at the minimum specified OMA.
2. Optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition between the 20% and 80% amplitudes relative to the logical 1 and 0 levels. This is measured through a 4th order Bessel -Thompson filter with 0.75 * Data Rate 3-dB bandwidth
and corrected to the full bandwidth value. Use of the 4G FC compliance filter results in an equivalent rise/fall time specification of 116 ps.
3. Optical Modulation Amplitude (OMA) is defined as the difference in optical power between a logic level one and a logic level zero. The Optical
Modulation Amplitude is defined in terms of average optical power (PAVG in μW) and extinction ratio (ER) as given by OMA=2PAVG((ER1)/(ER+1)). In this expression, the extinction ratio, the ratio of the average optical power (in μW) in a logic level one to the average optical power in
a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unit less linear) ratio
and not expressed in dB. The specified Optical Modulation Amplitude is equivalent to an average power of -7.3 dBm at an extinction ratio of 9 dB.
4. RIN12 is the laser noise, integrated over a specified bandwidth, measured relative to average optical power with 12dB return loss. See ANSI Fibre
Channel Specification Annex A.5.

2. The Vdd supply to the transceiver must remain valid for 25 + (N x 10) ms, where N is the number of bytes desired to write to the
scratch space (bytes 128-247 in 0xA2 address). For example: A single byte write will require 35 ms of valid supply voltage after the
Stop bit for that instruction is completed. A sequential multi-byte write of the entire 120 bytes into the user scratch space will require
the supply to remain valid for at least 1.23 s after the stop bit is completed.
3. The time from application of 3.0 V or greater Vdd supply at the transceiver voltage inputs to when the transceiver will be capable of
responding to a start sequence on the two-wire interface.

Serial ID Data Descriptions (Page/Device Address 0xA0)
All ID information is stored in eight-bit parameters addressed from 0x00 to 0x7F. All numeric information
fields have the lowest address in the memory space storing the highest order byte. The highest order bit is
always transmitted first. All numeric fields will be padded on the left with zeros. All character strings are
ordered with the first character to be displayed located in the lowest address of the memory space. All character strings will be padded on the right with ASCII spaces (0x20) to fill empty bytes.
Check Codes
The check codes contained within the identification data are one byte codes that can be used to verify that
the data in previous addresses is valid. CC_BASE check code is the lower eight bits of the sum of the contents of bytes 0-62. CC_EXT check code is the lower eight bits of the sum of the contents of bytes 64-94.

Internal Calibration
This transceiver contains internally calibrated values such that the values should be interpreted as follows:
Temperature: The temperature data is the internal transceiver temperature. The temperature is represented
as a 16-bit signed twos complement value in increments of 1/256 °C. This yields a value from -128 to +128 °C
but is only valid if within the operating specifications of the transceiver. Temperature accuracy is +/- 3 °C.
Voltage: The voltage data will be calibrated to the internally measured Transmit VDD supply. The voltage is
represented as a 16-bit unsigned integer with the voltage equal to the full 16-bit decimal value (0 to
65535)*100 μV. This yields a total range of 0 to 6.55 volts but is only valid if within the operating specifications
of the transceiver. Accuracy is +/-3% of nominal voltage (3.3 +/- 0.10 V)
TX Bias: The TX Bias data is calibrated to reflect the average current biasing the laser diode. The TX Bias is
represented as a 16-bit unsigned integer with the current value equal to the full 16-bit decimal value (0 to
65535)*2 μA. This yields a total range of 0 to 131mA but is only valid if within the operating specifications of
the transceiver. Accuracy is +/-10% of nominal value over specified operating temperature and voltage.
TX Power: The TX Power data is calibrated to reflect the average power coupled into a nominal fiber [7]. The
accuracy takes into account the fiber to fiber variation and also calibration test equipment accuracies. The TX
Power is represented as a 16-bit unsigned integer with the power value equal to the full 16-bit decimal value
(0 to 65535)*0.1 μW. This yields a total range of 0 to 6.55 mW but is only valid if within the operating specifications of the transceiver. Data is not valid when the transmitter is disabled. Accuracy is +/-2 dB over specified operating voltage and temperature.
RX Power: RX Power data is calibrated to reflect the average optical power exiting the ferrule of a nominal
fiber[7]. The accuracy takes into account the fiber to fiber variation and also calibration test equipment accuracies. The RX Power is represented as a 16-bit unsigned integer with the power value equal to the full 16-bit
decimal value (0 to 65535)*0.1 μW. This yields a total range of 0 to 6.55 mW but is only valid if within the
operating specifications of the transceiver. Accuracy is +/- 2dB over specified operating voltage and temperature.

Digital Diagnostic Monitor Data Offsets
The Digital Diagnostic Monitor Data page is a single 256-byte page with regard to read and write access offsets. There are no mini-page sections within the 256-byte space. Contiguous, sequential accesses, without
modifying the offset, will cycle through offsets 0 to 255 then return to offset 0.
Digital Diagnostic Monitor Data Write Access
The Digital Diagnostic Monitor Data page contains an area defined as a user writable, non-volatile scratch
space, that can be written to by the user, and which will be non-volatile across power cycles and resets. This
space can be accessed sequentially and contiguously within the offsets defined for it (refer to Monitor Data
Table 1 on page 32). If during the course of a sequential, multi-byte write, the offset being written reaches the
end of the user writable space, the next byte of data will be a write attempt to the vendor specific area.

Description of Fields
1. The Digital Diagnostic Monitoring values and Alarm/Warning indicators will be set to zero, and Data Ready Bar will be set high, for
certain failure mechanisms within the transceiver that do not affect the link capability of the transceiver. Refer to Vendor Specific
Digital Diagnostic Monitor TX_FAULT Alarm/Warning Interrupt on page 37 for additional information on transceiver Digital Diagnostic Monitoring status.
2. The data ready bar bit is held high during module power up and prior to the first transceiver sampling of the monitored values. The
bit will be set low after each first successful sampling occurs and remain low until the transceiver looses power or a failure occurs.
The bit must be set low within 1 second of reaching a valid stable power supply level.
3. Bytes 112-119 contain a set of non-latched alarm and warning flags. Users can choose to read these values and use them to analyze the status of the transceiver as an alternative to decoding the real-time values in bytes 96-105. Alarm flags indicate levels that
are likely to be associated with link failures. Warning flags indicate levels that are outside of normal levels, but not necessarily
cause for immediate concern (could be used for end-of-life indicators).

Vendor Specific Digital Diagnostic Monitor TX_FAULT Alarm/Warning Interrupt
The transceiver has the ability to be programmed to indicate TX_FAULT when one of the five DDM signals
goes outside an alarm or warning threshold. This allows the customer the option of using the TX_FAULT as
an interrupt instead of constantly polling the diagnostic signals. The TX_FAULT Alarm/Warning interrupt control bytes are accessible as one of the selectable tables in the Vendor specific area at offset 248-255.
To enable the TX_FAULT as an Alarm/Warning, use the following procedure:
This alarm/warning interrupt enable/latch space will be volatile across power-cycles and resets. This space
can be accessed sequentially and contiguously within the offsets defined for it. If during the course of a
sequential, multi-byte write, the offset being written reaches the end of this vendor specific area, the next byte
of data that will be attempted to be written will be at offset 0.
The Alarm/Warning Interrupt Enable bits are written by the host. They are used by the transceiver to generate
a TX_FAULT signal usable as an interrupt to the host for an alarm/warning condition. The general definition
of the function is that when the host sets an Interrupt Enable bit (offsets 248-251) for an Alarm/Warning to
0b1, then the corresponding Alarm/Warning Latch bit (offsets 252-255) will be latched to 0b1 when the corresponding Alarm/Warning bit (Alarm bits at offsets 112-113 and Warning bits at offsets 116-117) becomes
active. The Alarm/Warning Latch bit will remain 0b1 until the host clears the Latch bit by writing a 0b1 to it, at
which time the transceiver will re-process the Latch bit. While any of the Alarm/Warning Latch bits are a 0b1,
the transceiver will set the TX_FAULT signal active.
Note: When used in the Alarm/Warning Interrupt mode, the TX_FAULT signal does not necessarily indicate
that the transceiver is not transmitting. When TX_FAULT becomes active, the host should disable all
Alarm/Warning Interrupt Enable bits and clear all Alarm/Warning Latch bits In order to determine whether
there is a hardware TX_FAULT that does indicate hardware transmission loss.

Description of Fields
1. The alarm/warning interrupt enable bits are writable by the host to either 0b0 or 0b1. Their default value after a reset is 0b0. To
enable multiple bits, the host must write the byte at the appropriate offset with a value that is an OR of all bits that are to be set to
the interrupt enabled state.
2. The alarm/warning latch bits are only set to 0b1 by the transceiver, but can be cleared to 0b0 by the host writing a 0b1 to the appropriate bit position. Only those bits that are written to 0b1 will be cleared. Upon clearing a bit, the transceiver will re-process the
Latch bit, and if the corresponding alarm/warning bit is still active, and the corresponding interrupt enable bit is still set to 0b1, the
Latch bit will remain set to 0b1, thus causing TX_FAULT to remain active.
