Colorless ROADM features now part of Transmode Flexible Optical Networking portfolio

Transmode says it has added a colorless mux/demux module that enables colorless ROADM configurations to its Flexible Optical Networking line.

Transmode says it has added a colorless mux/demux module that enables colorless ROADM configurations to its Flexible Optical Networking line.

The new colorless 16-channel mux/demux module is available on Transmode’s TM-Series platforms. The new module’s colorless ROADM capabilities increase flexibility in traffic routing and restoration, Transmode says. In conjunction with tunable optics in traffic units, the new module also enables remote provisioning and reconfiguration of wavelengths without the need for onsite visits after a traffic unit has been connected to the new colorless module, the company adds.

"Transmode's Flexible Optical Networking portfolio has seen rapid growth in deployments over recent quarters with a large percentage of new design wins utilizing this portfolio," said Sten Nordell, Transmode's CTO. "Several of our recently announced customer wins use this approach as the basis for a broad range of applications. This shows the importance of these networks and Transmode's success in this space. This new product will further strengthen this offering."

The TM-Series contains two-, four-, and eight-degree ROADM modules that enable network operators to selectively build a range of ROADM nodes for a wide range of applications. These nodes can be standard ROADM nodes or directionless or contentionless configurations. The addition of the colorless mux/demux enables what is known as colorless, directionless and contentionless (CDC) ROADM nodes.

"This new development adds valuable new capabilities to the TM-Series in the important area of Flexible Optical Networks," said Dave Dunphy, principal analyst at Telecom Strategy Partners. "The key development here beyond creating a product with the best price and performance, was the integration of these capabilities into Transmode's management platform, the Transmode Network Manager. These solutions are often deployed in sophisticated networks that encompass a Flexible Optical Network base layer with a combination of Layer 1 and Layer 2 services. Providing powerful multi-layer management of these large and complex networks is therefore vitally important."
