Notes:
1. Module ground pins GND are isolated from the module case and chassis ground within the module.
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 KΩ resistor.
3. These are the differential receiver outputs. They are DC coupled is done inside the module (See
