1 Gbps SFP Shortwave Transceiver PL-XPL-00-S13
Accelar™
1 Gbps SFP Shortwave Transceiver
PL-XPL-00-S13
The 1G Small Form Factor Pluggable (SFP) transceiver
provides superior performance in Fibre Channel short
reach Gigabit Ethernet applications. It is a star performer
in Picolight’s family of Accelar products customized for
high speed, short reach LAN, SAN and intra-POP
applications. The 1G SFP features Picolight’s highly
reliable 850 nm oxide vertical-cavity surface-emitting
laser (VCSEL) coupled to a LC optical connector. Its small
size allows for high-density board designs that, in turn,
enable greater total aggregate bandwidth. The
pluggability of the module design further allows
manufacturers to populate the optical ports later in the
build cycle, providing a just-in-time inventory and cost
control. The 1G SFP complies with Fibre Channel
100-M5/M6-SN-1 and 802.3z 1000BASE-SX standards.
Key benefits

1 Gbps SFP Shortwave Transceiver
Section 1
Functional description
The PL-XPL-00-S13 850 nm VCSEL Gigabit Transceiver is designed to transmit and receive 8B/10B
encoded serial optical data over 50/125 µm or 62.5/125 µm optical fiber.
Transmitter
The transmitter converts 8B/10B encoded serial PECL electrical data into serial optical data meeting
the requirements of Fibre Channel 100-M5/M6-SN-I and IEEE 802.3z 1000 Base-5x specifications.
Transmit data lines (TD+ & TD-) are internally AC coupled with 100 Ω differential termination.
An open collector compatible Transmit Disable (TDis) is provided. This pin is internally terminated with
a 10 kΩ resistor to Vcct. A logic “1,” or no connection on this pin will disable the laser from transmitting.
A logic “0” on this pin provides normal operation.
The transmitter has an internal PIN monitor diode that is used to ensure constant optical power output
across supply voltage and temperature variations.
An open collector compatible Transmit Fault (TFault) is provided. The Transmit Fault signal must be
pulled high on the host board for proper operation. A logic “1” output from this pin indicates that a
transmitter fault has occurred, or the transceiver is not fully seated and the transmitter is not
functioning. A logic “0” on this pin indicates normal operation.
Receiver
The receiver converts 8B/10B encoded serial optical data into serial PECL electrical data. Receive
data lines (RD+ & RD-) are internally AC coupled with 100 Ω differential source impedance, and must
be terminated with a 100 Ω differential load.
An open collector compatible Loss of Signal is provided. The LOS must be pulled high on the host
board for proper operation. A logic “0” indicates that light has been detected at the input to the receiver
(see Section 3.4 Optical characteristic, Loss of Signal Assert/Deassert Time on page 8). A logic “1”
output indicates that insufficient light has been detected for proper operation.
Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed
on the host assembly as close to the Vcc pins as possible for optimal performance.
Recommended “Application Schematics” are shown in Figure 2 on page 5.

Notes
!
Power supply filtering components should be placed as close to the Vcc pins of the host connector as
possible for optimal performance.
!!
PECL driver and receiver will require biasing networks. Please consult application notes from suppliers
of these components.
!!!
MOD_DEF(2) and MOD_DEF(1) should be bi-directional open collector connections in order to
implement serial ID (MOD_DEF[0,1,1]) PL-XPL-00-S13 transceiver.
*
Transmission lines should be 100 Ω differential traces. It is recommended that the termination resistor for
the PECL Receiver (R3 + R4) be placed beyond the input pins of the PECL Receiver. Series Source
Termination Resistors on the PECL Driver (R1+R2) should be placed as close to the driver output pins as
possible.

Specification notes
1. UI (Unit Interval): one UI is equal to one bit time. For example, 1.125 Gbits/s corresponds to a
UI of 880ps.
2. For LOSA and LOSD definitions see Loss of Signal Assert/Deassert Level in Section
3.4 Optical characteristic on page 9.
3. SERDES typically supply 1600 mVp-p (differential). Therefore, attenuation of the transmitted
signal may be necessary to meet the maximum data input voltage swing specification. It is
recommended that series 50 Ω source terminating resistors be placed as close to the
SERDES output as possible to attenuate the signal, improve EMI, and improve signal integrity.
4. Measured with stressed eye pattern as per FC-PI (Fibre Channel) using the worst case
specifications.
5. For optical modulation bandwidth, sensitivity, and stressed sensitivity specifications, see
Section 3.4 Optical characteristic on page 9.
6. Distances, shown in the “Link Length” table, are the distances specified in Fibre Channel and
IEEE 802.3z standards. “Link Length” distances are calculated for worst case fiber and
transceiver characteristics based on the optical and electrical specifications shown in this
document using techniques utilized in IEEE 802.3z (Gigabit Ethernet). In the nominal case,
longer distances are achievable.
7. New Bandwidth Enhanced MMF.

Annex A - Serial ID operation
The PL-XPL-00-S13 is equipped with a 2-wire serial EEPROM that is used to store information about
the module. See Section IV, “Module Definition Interface and Data Field Description” of the SFP-MSA
Pin Definitions and Host Board Layout document. The information is accessed through the
MOD_DEF(1), and MOD_DEF(2) connector pins of the module.

Reading the data
The specification for this EEPROM (ATMEL AT24CO1A Type) contains all the timing and addressing
information required for accessing the data.
MOD_DEF(0), pin 6 on the PL-XPL-00-S13 transceiver, is connected to Logic 0 (Ground) on the
transceiver.
MOD_DEF(1), pin 5 on the PL-XPL-00-S13 transceiver, is connected to the SCL pin of the
EEPROM.
MOD_DEF(2), pin 4 on the PL-XPL-00-S13 module, is connected to the SDA pin of the
EEPROM.
The EEPROM WP pin is internally tied to Vcc with no external access, permanently protecting the data
stored within. Any write commands will be ignored.
The device address pins, A0, A1, and A2, are connected to the ground, fixing the device address used
to read data [10100001], any other device addresses will be ignored.
Decoding the data
The information stored in the EEPROM including organization is defined in the Small Form-Factor
Pluggable Multisource (SFP-MSA) Pin Definitions and Host Board Layout document, dated 3/13/00,
Section IV.
4.2
Package and handling instructions
Process plug
The PL-XPL-00-S13 is supplied with a dust cover. This plug protects the transceiver’s optics during
standard manufacturing processes by preventing contamination from air borne particles.
Note:
It is recommended that the dust cover remain in the transceiver whenever an optical
fiber connector is not inserted.
Recommended cleaning and de-greasing chemicals
Picolight recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning.
Do not use halogenated hydrocarbons (e.g. trichloroethane, ketones such as acetone, chloroform,
ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability
The PL-XPL-00-S13 housing is made of cast zinc.
4.3
ESD Discharge (ESD)
Handling
Normal ESD precautions are required during the handling of this module. This transceiver is shipped in
ESD protective packaging. It should be removed from the packaging and handled only in an ESD
protected environment utilizing standard grounded benches, floor mats, and wrist straps.

1 Gbps SFP Shortwave Transceiver
Test and operation
In most applications, the optical connector will protrude through the system chassis and be subjected
to the same ESD environment as the system. Once properly installed in the system, this transceiver
should meet and exceed common ESD testing practices and fulfill system ESD requirements.
Typical of optical transceivers, this module’s receiver contains a highly sensitive optical detector and
amplifier which may become temporarily saturated during an ESD strike. This could result in a short
burst of bit errors. Such an event might require that the application re-acquire synchronization at the
higher layers (e.g. Serializer/Deserializer chip).
4.4
Eye safety
The PL-XPL-00-S13 is an international Class 1 laser product per IEC 825-1: 1993, and per CDRH, 21
CFR 1040 Laser Safety Requirements. The PL-XPL-00-S13 is an eye safe device when operated
within the limits of this specification.
Operating this product in a manner inconsistent with intended usage and specification may result in
hazardous radiation exposure.
CAUTION!
Tampering with this laser based product or operating this product outside the limits of this specification
may be considered an act of “manufacturing,” and will require, under law, recertification of the modified
product with the U.S. Food and Drug Administration (21 CFR 1040).
CAUTION!
The use of optical instruments with this product will increase eye hazard. At the normal operating
current, optical output power with an unaided eye can be as much as 30 uW at a wavelength of 850
nm. Approximately ten times this power level could be collected with an eye loupe. Under a failure
condition, this level could increase by a factor of two.
