Notes:
1.
Circuit ground is internally isolated from chassis ground.
2.
Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
3.
Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 5.5V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
4.
Receiver achieves multi-rate operation without active control.
5.
LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and
5.5V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
