PROBLEM POSSIBLE CAUSE

3. No optical power, LED

not illuminated.

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.

4. Optical power light

illuminated with

disconnected optical

input.

Damaged (leaky) photodiode. Unit may still

function, otherwise contact Factory for service.
