Notes:
1.
TX Fault is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host
board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a
laser fault of some kind. In the low state, the output will be pulled to less than 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 4.7k~10kΩ resistor. Its states are:
Low (0~0.8V):

MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10kΩ resistor 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 ID
4.
LOS is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board
to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of
signal. In the low state, the output will be pulled to less than 0.8V.
5.
These are the differential receiver outputs. They are AC-coupled 100Ω differential lines which should be
terminated with 100Ω (differential) at the user SERDES.
6.
These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω
differential termination inside the module.
