Cisco GainMaker Optoelectronic Node 1GHz with 65 86 MHz Split Installation Guide

3  The station reverse input pad(s), reverse output pad, and reverse transmitter 

input pad are selected during the reverse system design and are based on the 

services to be transported by the reverse system. DO NOT CHANGE ANY OF 

THESE PADS FROM THEIR DESIGN VALUES! The reverse equalizer value may 

be changed if needed to obtain flat receiver output levels across the reverse  

frequency spectrum. 

4  Have the technician in the headend refer to the headend system design and set 

the output of the optical receiver to the specified output level. If using a sweep 

system that is x dB below standard design levels, be sure to consider that your 

receive level should also be x dB below the original design reference level. 
See the instruction guide that was shipped with the optical receiver for setup 

procedures. It may be necessary to use an external attenuator at the RF output of 

the optical receiver, if the receiver does not have an RF output level adjustment 

control. 
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. 

 
 

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 

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
