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):
