1.
Circuit ground is internally isolated from chassis ground.

T
FAULT
is 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.
Internally pulled down per SFF-8431 Rev 2.0.
5.
LOS is open collector output. Should be pulled up with 4.7k – 10k
Ω on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
