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 – 10 kohms on host board to a voltage between 2.0V and

3.6V.MOD_DEF(0) pulls line low to indicate module is plugged in.

    1. Rate select is not used
    2. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
