1.4.2 Single Y-Cable Protection Module
The Y-cable protection module is a bidirectional module. It is equipped with two passive star couplers:
one that is used as a splitter and one that is used as a coupler.
Note None of the modules in this equipment release can be used for video on demand (VoD) applications.
Note The ADM-10G card, which can be provisioned as either a transponder or muxponder, does not support
Y-cable protection.
The purpose of this module is to provide Y-cable protection on the CLIENT side of transponder (TXP)
cards such as the TXP_MR_10G, TXP_MR_10E, or TXP_MR_2.5G (Figure 1-10). There are two
versions of this module, one for multimode applications (CS-MM-Y) and one for single-mode
applications (CS-SM-Y).
Using one Y-cable protection module, you can protect one client signal with two TXP cards, and two
client signals with four TXP cards.
