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. 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 ¨C 10 K Its states are: Low (0 to 0.8V):              Transmitter on (>0.8, < 2.0V):                Undefined High (2.0 to 3.465V):                           Transmitter Disabled Open:                           Transmitter Disabled Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K to 10K resistor on the host 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 LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 7K to 10K resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates the received opticalpower 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. RD-/+: These are the differential receiver They are AC coupled 100 differential lines which should be terminated with 100 (differential) at the user SERDES. TD-/+: These are the differential transmitter They are AC-coupled, differential lines with 100 differential termination inside the module. The GOXS-C12-02 has an input voltage range of +3.3V +/- 5%. The 3.3V maximum voltage is not allowed for continuous operation.
