Notes :

1	TX Fault is an open collector output, which should be pulled up with a 4.7k~10k 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~10k resistor. Its states are: Low (0~0.8V): Transmitter on (>0.8V~<2.0V): Undened High (2.0~3.465V): Transmitter Disabled Open: Transmitter Disabled
3	MOD-DEF 0,1,2 are the module denition pins. They should be pulled up with a 4.7k~10k 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~10k 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 dierential receiver output. They are internally AC-coupled 100 dierential lines which should be terminated with 100 (dierential) at the user SERDES.
6	These are the dierential transmitter inputs. They are AC-coupled, dierential lines with 100 dierential termination inside the module.
