Notes:
1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KW resistor on the host board to a supply < Vcc + 0.3
2. TX disable input is used to shut down the laser output per the state table below with an external 4.7-10 KW4 pull-up resistor.
3. Mod-Def0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KW resistor on the host board to a supply less than VccT
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KW resistor on the host board to a supply
5. VeeR and VeeT may be internally connected within the SFP module
6. RD-/+: These are the differential receiver outputs. They are ac coupled 100 W differential lines which should be terminated with 100 W differential at
7. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.1 – 3.5 V at the SFP connector pin. The maximum supply
8. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100 W differential termination inside the module. The

V. When high, this output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to < 0.8 V.
Low (0 – 0.8 V):
Between (0.8 V and 2.0 V): Undefined
High (2.0 – 3.465 V):
Open:
(0.3 V or VccR + 0.3 V.
Mod-Def 0 is grounded by the module to indicate that the module is present
Mod-Def 1 is clock line of two wire serial interface for optional serial ID
Mod-Def 2 is data line of two wire serial interface for optional serial ID
< VccT,R + 0.3 V. 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 < 0.8 V. Please see later section for LOS timing.

current is 300 mA.
ac coupling is done inside the module and is thus not required on the host board. The inputs will accept differential swings of 500 – 2400 mV (250 –
1200 mV single ended).
