TX Fault is an open collector output, which should be pulled up with a 4.7 k~10 kΩ resistor on the host board to a voltage between 2.0 V 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 0.8 V.
TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 k~10 kΩ resistor.
Its states are:
Low (0~0.8 V):
(>0.8V, <2.0V):
High (2.0~3.465V):
Open:
MOD-DEF 0,1,2 are the module defi nition pins. They should be pulled up with a 4.7 k~10 kΩ 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 wires serial interface for serial ID
MOD-DEF 2 is the data line of two wires serial interface for serial ID
LOS is an open collector output, which should be pulled up with a 4.7 k~10 kΩ resistor on the host board to a voltage between 2.0 V 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 0.8 V.
These are the diff erential receiver output. They are internally AC-coupled 100 Ω diff erential lines which should be terminated with 100 Ω
(diff erential) at the user SERDES.
These are the diff erential transmitter inputs. They are AC-coupled, diff erential lines with 100 Ω diff erential termination inside the module.
