Ciena NXWCC42E 09M WMI4FY0AAB WCI3RL Wavelength Converter Interface

The Ciena NXWCC42E Wavelength Converter Interface is a WCI module from Ciena's NXWCC family, intended for metro-scale wavelength conversion in DWDM networks. Marketed as an Enhanced WL Converter Interface Metro 23, it is used where shifting a signal's optical wavelength is needed to align with available fiber paths or to enable reconfigurable networking. The NXWCC family includes variants such as NXWCC34E, described as an "oline metro enhanced wavelength converter interface," indicating the lineage and typical metro-focused role of these interfaces. This product supports integration with Ciena's broader wavelength-management ecosystem, enabling flexible service provisioning in metro core and access rings.
