Received Laser Power (dBm) – This is the
amount of Laser power being received. It
indicates how much attenuation has been
applied to the signal.
Channel Changeover - The ‘changeover’
option allows the output of optical receiver 1 to
be routed to the reclocker on channel 2
providing a simple signal routing capability or
the ability to provide a redundant signal path
for critical signals. The table shows the various
options available to the user to enable the
changeover function and then facilitate the
actual routing of the channel 1 signal to the
channel 2 outputs. The ‘changeover’ function
can be ‘enabled’ via manual
or
remote control
switches. Note: The manual control switches
are the overall master controls for this function.
