Description
This test point enables monitoring of the optical output level of the module.
The nominal scale factor is 0.5 V/mW. Note that the optical power test point
does not track changes in optical power due to the laser tracking error.
A red LED (
) indicates that the laser output power is below normal
FAULT
limits. Because the laser output requires a short period of time to stabilize, it
is normal for the LED not to illuminate for approximately 10 seconds. Note
that the module must be enabled for the fault indicator to function.
A green LED (
) provides visual indication of the transmitter's enable
ENABLE
status.
