       Notes:

    1.  Circuit ground is internally isolated from chassis ground.

    2.  TFAULTis an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on

    the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high

    output indicates a transmitter fault caused by either the TX bias current or the TX output power

    exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the

    output is pulled to <0.8V.

    3.  Laser output disabled on TDIS>2.0V or open, enabled on TDIS<0.8V.

    4.  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.

    5.  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.
