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 4.7 – 10 K Ω resistor. Its states are:
Low (0 – 0.8V): Transmitter on (>0.8, <2.0V): UndefinedHigh (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K –10KΩresistor on the host board. The pull-up voltage shall be VccT or VccR. Mod-Def 0 is grounded by
the module to indicate that the module is present Mod-Def 1 is the clock line of two wire serial interface
for serial ID Mod-Def 2 is the data line of two wire serial interface for serial ID4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K –Data Controls Inc.

V2.aBIDI SFP Series
10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates thereceived 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) VeeR and VeeT may be internally connected within the SFP module.
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 bebetween 370 and 2000 mV differential (185 –1000 mV single ended) when properly terminated.
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5% atthe SFP connector pin. Maximum supply current is 300mA. Recommended host board power supply
filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used in order tomaintain 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 internallyconnected within the SFP transceiver module.
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with100Ω 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 400 – 2000 Mv (250 –1200Mv single-ended), though it is recommended that values between 500 and 1200 Mv differential(250 – 600Mv single-ended) be used for best EMI performance.

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 serialclock signal (SCL). The positive edge clocks data into those segments of the EEPROM that are notwrite 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 aseries 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 powermonitoring, bias current monitoring, supply voltage monitoring and temperature monitoring all areimplemented. 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, pleaserefer to the related document of SFF 8472 Rev 9.3.
