Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor
on the host board. Pull up voltage between 2.0V and VccT/R+0.3V. When high, output indicates a
laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled
to < 0.8V.
2) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up
within the module with a 4.7K – 10 KΩ resistor. Its states are:
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Module Absent, connected to VeeT or VeeR in the module.
4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K –
10KΩ resistor. Pull up voltage between 2.0V and VccT/R+0.3V. When high, this output indicates
the received optical power is below the worst-case receiver sensitivity (as defined by the standard
in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
5) The module signal ground contacts, VeeR and VeeT, should be isolated from the module case.
6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines
which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done
inside the module and is thus not required on the host board. The voltage swing on these lines will
be between 350 and 700 Mv differential (175 –350 Mv single ended) when properly terminated.
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5%
at the SFP+ connector pin. Maximum supply current is 680Ma. Recommended host board power
supply filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used in
order to maintain the required voltage at the SFP+ input pin with 3.3V supply voltage. When the
recommended supply-filtering network is used, hot plugging of the SFP+ transceiver module will
result in an inrush current of no more than 30Ma greater than the steady state value. VccR and
VccT may be internally connected within the SFP+ transceiver module.

SFP+ Series
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with
100Ω differential termination inside the module. The AC coupling is done inside the module and is
thus not required on the host board. The inputs will accept differential swings of 150 – 1200 Mv (75
– 600Mv single-ended).
Rate Select Control
Transceiver data rate selected through the 2-wire bus in accordance with SFF-8472 Rev.10.3. Soft
RS0 is set at Bit 3, Byte 110, Address A2h. Soft RS0 default state on power up is ‘0’ LOW, and the
state is reset following a power cycle. Writing ‘1’ HIGH selects max. data rate operation.
Transceiver data rate is the logic OR of the input state of the RS0 pin and soft RS0 bit. Thus, if
either the RS0 pin OR the soft RS0 bit is HIGH then selected data rate will be 9.95 and 10.3Gb/s.
Conversely, to select data rate 1.25Gb/s both the RS0 pin and the soft RS0 bit are set LOW.

EEPROM
The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMEL
AT24C02/04 family of components. When the serial protocol is activated, the host generates the
serial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM that
are not writing protected within the SFP+ transceiver. The negative edge clocks data from the
SFP+ transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The host
uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The
memories are organized as a series of 8-bit data words that can be addressed individually or
sequentially.
The Module provides diagnostic information about the present operating conditions. The
transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and
alarm/warning threshold data is written during device manufacture. Received power monitoring,
transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature
monitoring all are implemented. If the module is defined as external calibrated, the diagnostic data
are raw A/D values and must be converted to real world units using calibration constants stored in
EEPROM locations 56 – 95 at wire serial bus address A2h. The digital diagnostic memory map
specific data field define as following .For detail EEPROM information, please refer to the related
document of SFF 8472 Rev 10.2.
