T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on FAULT 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 T >2.0V or open, enabled on T <0.8V. DIS DIS 4. Internally pulled down per SFF-8431 Rev 4.1. 5. LOS is open collector output. Should be pulled up with 4.7k 10k on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. 6.
