POSSIBLE CAUSE
1. There is a break or severe bend in the fiberoptic
cable. Use an optical power meter or another
functioning receiver unit to verify optical
power coming down the fiber.
2. Optical power too low, too many splits, too
long a distance (thus exceeding optical budget).
System may still function without LED
illuminated although at reduced performance.
3. The transmitter is not functioning, see above.
Damaged (leaky) photodiode. Unit may still
function, otherwise contact Factory for service.
