Industrial NTK553FC Optical Transceiver Module

NTK553FC is a 50 GHz WSS circuit pack designed for C-band operation in Ciena/Nortel 6500 Packet-Optical platforms. The module is specified as 50 GHz with Optical Performance Monitoring (OPM) in a 9x1 arrangement, enabling per-wavelength control within the DWDM grid and straightforward integration as part of a WSS-based deployment. In the 6500 system family, it provides flexible wavelength routing to add, drop, or pass through individual channels on the C-band, supporting dynamic reconfiguration of the optical transport without requiring full-scale lane changes. OPM capability offers channel-level monitoring of optical power and related metrics, aiding performance management and fault isolation in dense networks. Typical applications include metropolitan ring networks and long-haul DWDM links where precise, rapid reconfiguration of wavelengths is required to optimize capacity, resiliency, and service uptime. The NTK553FC is commonly used alongside other NTK553xx circuit packs to assemble modular, scalable WSS-based solutions within the 6500 platform, delivering granular control over the C-band DWDM spectrum on 50 GHz spacing.
