Cisco ONS 15216
8-Channel Filter Module

The FlexLayer architecture allows for deployment of point-to-point, point-to-multipoint, ring, bus, and tree-and-branch architectures. These networks can be deployed as unprotected or protected networks, and they may also be deployed in transmit-only applications for broadcast networks. This flexibility is inherent in the design of the FlexLayer architecture.

All Cisco ONS 15216 FlexLayer modules can be populated in a 1-rack-unit 19- or 23-inch rack-mountable chassis. This unit offers four module slots arranged horizontally. Each slot can accommodate one multiplexer, demultiplexer, combiner, or splitter module. Two slots, either the two rightmost or two leftmost, can accommodate a variable optical attenuator (VOA) module.

The Cisco ONS 15216 8-channel filter assembly (Figure 1) is a passive unit comprising a 100-gigahertz (GHz) 8-x-1 wavelength unidirectional multiplexer or a 100-GHz 1-x-8 wavelength unidirectional demultiplexer. This unit, used either as a multiplexer or demultiplexer, can be upgraded in the field in the desired application. Four independent modules make up a 32-channel C-Band wavelength plan. The multiplexer or demultiplexer module connects independent fibers to the carrier's fiber facilities through the common ports on the chassis faceplate. Additional units can be added in service in multiple methods that offer benefits to each application. Each device incorporates a monitoring port of the composite signal along with an express port that can be used to cascade the filters together. This module is one slot wide in the FlexLayer chassis.
