Notes:

1. TX Fault is an open collector output, which should be pulled up with a 4.7k~10k

Ω 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
