EEPROM Information Functions
Serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. SFP transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage.
It also defines a sophisticated system of alarm and warning flags, which alerts end users when particular operating parameters are outside of a factory-set normal range.
Defines a 256-byte memory map in E²PROM that is accessible over a 2-wire serial interface at the 8-bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8-bit address 1010001X (A2h). The interface is identical to, and compatible with both the GBIC Specification and the SFP Multi-Source Agreement.

Pin Function Notes
Note 1 — TX_Fault: Open collector/drain output, should be pulled up with a 4.7kΩ–10kΩ resistor on the host board. Pull-up voltage between 2.0V and VCCT+0.3V. When high, output indicates a laser fault. Low indicates normal operation (< 0.8V).
Note 2 — TX_Disable: Input for shutting down the transmitter optical output.
Low (0–0.8V): Transmitter on | (>0.8, <2.0V): Undefined | High (2.0–VCC): Transmitter Disabled | Open: Transmitter Disabled
Note 3 — Mod-Def 0, 1, 2: Module definition pins, should be pulled up with a 4.7kΩ–10kΩ resistor. Mod-Def 0 is grounded by the module to indicate presence. Mod-Def 1 is the clock line of the 2-wire serial interface. Mod-Def 2 is the data line.
Note 4: Not in used.
Note 5 — LOS: Open collector/drain output, pulled up with a 4.7kΩ–10kΩ resistor. When high, indicates received optical power is below worst-case receiver sensitivity. Low indicates normal operation (< 0.8V).
Note 6: VeeR and VeeT may be internally connected within the SFP module.
Note 7: VccR and VccT are the receiver and transmitter power supplies, defined as 3.3V ±5%. Maximum supply current is 300mA. VccR and VccT may be internally connected.
Note 8: RD-/+: Differential receiver outputs, AC-coupled 100Ω differential lines. AC coupling is done inside the module.
Note 9: TD-/+: Differential transmitter inputs, AC-coupled with 100Ω differential terminations inside the module.
