FlexLayer

Filter Solution

The Cisco ONS 15216 Metropolitan Dense Wavelength-Division Multiplexing

(DWDM) FlexLayer filter solution is an ultraflexible filter architecture that allows

cable multiple system operators and service providers to build “pay-as-you-grow”

networks with the flexibility to upgrade in-service without preprovisioning channels

that are not required. This approach creates a more desirable per-wavelength cost.

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.

Chassis

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.

8-Channel Filter

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.
