   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.
