Feature	Description
Transmitter enable	A green LED that provides visual indication of the transmitter’s
	enable status.
Fault indicator	A single red LED that lights if the hybrid current is outside the
	normal operating range, the laser output power is below normal
	limits, or the laser current is above normal limits. Because the laser
	output requires a short period of time to stabilize, it is acceptable
	for the fault indicator to illuminate during the stabilization interval
	(approximately 2 seconds). Note that the module must be enabled
	for the fault indicator to function.
