Notes:
1. TX Fault is an open collector/drain output which should be pulled up externally with a 4.7K – 10 KΩ resistor on the host board to a supply <
3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10 KΩ resistor on the host board to a supply less
4. LOS (Loss of Signal) is an open collector/drain output which should be pulled up externally with a 4.7 K – 10 KΩ resistor on the host board to a
5. RD-/+: These are the differential receiver outputs. They are AC coupled 100 Ω differential lines which should be terminated with 100 Ω differ-
6. VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.135 – 3.465 V at the SFP connector pin. The in-rush cur-

than
supply < 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 operatio0n. In the low state, the output will be pulled to < 0.8 V.
ential 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 must be between 370 and 2000 mV differential (185 – 1000 mV single ended) according to the MSA. Typically it will be 1500mv differen-
tial.
rent will typically be no more than 30 mA above steady state supply current after 500 nanoseconds.
ule. The 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). However, the applicable recommended differential voltage swing is found in Table 5.
