Cisco GainMaker Optoelectronic Node 1GHz with 42 54 MHz Split Installation Guide
Balancing the Reverse Path
Note: If the required output level of the reverse receiver is not known, set up the
longest optical link first. Set the remaining receivers for the same RF output level
as that of the receiver connected to the longest optical link.
5 Once the reverse fiber link has been properly balanced, the reverse RF amplifier
cascades feeding the node can be balanced.
To Prepare the Amplifier for Initial Reverse Path Balancing
Complete the following steps for initial reverse path balancing.
1 Balance all of the reverse amplifiers off a given reverse input port for the node
1 Balance all of the reverse amplifiers off a given reverse input port for the node
being worked on. The reverse amplifiers should be balanced sequentially from
the node outward.
Note: Make sure the reverse fiber link has been properly balanced before
Note: Make sure the reverse fiber link has been properly balanced before
proceeding.
2 Ensure that the design value reverse output equalizer and reverse pads are
installed in the appropriate reverse slots in the amplifier. Refer to the following
diagram.
