C-F/CD-F ROADM Reconfigurable Multiplexer

Multi-degree C-F/ CD-F ROADM nodes

COMD-2-8

COMD-3-4

FROADM-9/1

• Support for up to 9 (20) directions per node
• Support for C-F/CD-F functionality
• Add/drop up to 96 channels in the current terminal connection
• Monitoring and equalization of the channel spectrum

Reconfigurable Add/Drop Multiplexers FROADM-9/1 help to build multi-degree nodes that support the following functionality: flexible channel grid (F — FlexGrid), connection of any wavelength to any port with the possibility of remote wavelength reconfiguration (C — Colorless), channel add/drop from any port to any direction with the possibility of remote change of direction (D — Directionless). It is possible to monitor and equalize the channel spectrum at the Line Out output.

FROADM-1/9 Reconfigurable Multiplexers. Used to organize terminal CD-F connections. They have nine bidirectional add/drop ports.

Reconfigurable Multiplexers FROADM2-20/1 help to build multi-degree nodes that support C-F/CD-F functionality. There are 20 add/drop ports. It is possible to monitor and equalize the channel spectrum at the Line In input and the Line Out output.

"Colorless" multiplexers COMD-x-y are used to increase connected channels in C-F/CD-F termination. Modifications: COMD-3-4 — three pairs of passive optical splitters for four connections each, COMD-2-8 — two pairs of splitters for 8 connections each.
