Note
1. TFAULT 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.
2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS
<0.8V
3. Should be pulled up with 4.7kΩ-10kΩ on host board to a voltage
between 2.0V and 3.6V. MOD_ABS pulls line low to indicate
module is plugged in.
4. LOS is open collector output. Should be pulled up with
4.7kΩ-10kΩ on host board to a voltage between 2.0V and 3.6V.
