Notes:
7.1 Circuit ground is internally isolated from chassis ground.
7.2 Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
7.3 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.
7.4 LOS is open collector 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.
