Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
with a 4.7 – 10 K Ω resistor. Its states are:
host board. The pull-up voltage shall be VccT or VccR (see Section IV for further details). 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 ID
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.
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 370 and 2000 mV differential
(185 – 1000 mV single ended) when properly terminated.
TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor on the host
TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module

Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K – 10KΩresistor on the
LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ resistor.
VeeR and VeeT may be internally connected within the SFP module.
RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be
