Notes

1. Circuit ground is internally isolated from chassis ground.

2. Laser output disabled on TX Disable >2.0V or open, enabled on TX Disable<0.8V.

3. Should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V.

MOD_DEF(0) pulls line low to indicate module is plugged in.

4. LOS is LVTTL output. Should be pulled up with 4.7k ~10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
