AC Coupled. 19 TD- Transmitter Inverted DATA in. AC Coupled. 20 V Transmitter Ground (Common with Receiver Ground) 1 EET Notes: 1. Circuit ground is internally isolated from chassis ground. 2. T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on the host board if FAULT 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 T >2.0V or open, enabled on T <0.8V. DIS DIS 4. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V. MOD ABS pulls line low to indicate module is plugged in. 5. 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. Finisar Corporation August 2015 Rev.
