What is WXC | Wavelength Crossconnect ROADM type

This page explains basics of WXC(Wavelength Crossconnect) used in fiber optical domain. It mentions function of Wavelength Crossconnect ROADM type.

Wavelength Cross Connect-WXC ROADM

EXAMPLE: For degree N node (N directions, with N input fibers and N output fibers) and M wavelengths per fiber, a WXC needs N de-muxes, N muxes, and M number of N x N switches.

Figure depicts degree 8 node with 40 channels used in a mesh network. Here WXC consists of 8 number of 40 channel MUX/DEMUX pairs and 40 number of 8 x 8 switches.

Each 8 x 8 switch will operate on single wavelength. It can switch from any input fiber to any output fiber. Hence it provides true colorless ports.

Following are the features of WXC (Wavelength Cross Connect) type of ROADM:

• It provides N x N connectivity for mesh networks.

• Non blocking reconfigurable node

• Reliable configuration

• No regeneration

• No wavelength conversion
