Notes：
1. TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10K. resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output will be pulled to <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 4.7 – 10 K. resistor.
3. These are the module definition 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 (see Section IV for further details).
4. LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K – 10K. resistor. 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.
