Cisco GainMaker Optoelectronic Node 1GHz with 65 86 MHz Split Installation Guide
Chapter 3 Balancing and Setup
With a Segmented Reverse Path configuration, there are two reverse paths with two
output pads and two optical transmitters. Port 1 and Port 2 signals are combined and
passed to Rev1 Out. The signals at Rev1 Out and Rev2 Out are then passed to
transmitter TX 1. Port 3 and Port 4 signals are combined and passed to Rev2 Out.
The signals are then passed to transmitter TX 2 as shown in the following diagram.
Reverse path segmentation is accomplished using the plug-in (part number
4015162).
Combined Reverse Path with Double Transmitter Redundancy
With a Combined Reverse Path configuration, all reverse paths are combined and
passed to Rev1 Out. Rev2 Out is unused and is terminated by the plug-in modules.
The combined signals at Rev1 Out can be routed to both transmitters to provide
redundancy. This is accomplished using the reverse path plug-in (part number
4015165), as shown in the diagram. Note that the reverse path plug-in provides a 75
ohm termination for the unused output of Rev2 Out.
