Detailed System Description
Power Monitoring Scenarios
The following diagrams illustrate operational scenarios in which the Optical Power Indicator
LEDs provide a visual indication of the CopperHead 3430AP fiber optical status.
This scenario is a good operational situation. The ‐
6 dBm reflects typical signal strength across a Fiber
Optic cable run. The CopperHead 3430AP system
will run perfectly at this signal strength.
This scenario shows a bad Fiber Optic link and no
Optical Power in either direction. Check to see if
there is a problem with the Fiber Optic connection
or cable.
This scenario shows just enough Optical Power
present to provide an operational link. Check the
Fiber Optic cable run for possible damage or phys‐
ical interference such as sharp bends in the cable.
Also check the Fiber Optic connectors for dust, dirt
or damage.
This scenario shows low Optical Power but more
than adequate for a usable link. Keep an eye on
the reading to make sure it is consistent. Check
the cable run as above and check the Fiber Optic
connectors for dust, dirt or damage.
