Ciena NTT862AAE5 W0M5A00ARA Optical Mux-Demux Module

The NTT862AAE5 is a 44-channel Mux/Demux (CMD44) module purpose-built for Ciena’s 6500 Photonic Layer, delivering high-density C-band DWDM channel management at a fixed 100 GHz ITU spacing so operators can multiplex 44 individual wavelengths onto a single fiber path and then demultiplex them at the receiving node for upstream processing, monitoring, and routing. It is designed to operate within the Ciena photonic ecosystem and supports passive C-band photonic-layer configurations used in DWDM deployments, working alongside line amplifiers and ROADMs to preserve channel integrity and spectral efficiency across the C-band. The CMD44 family includes the standard NTT862AAE5 and an enhanced variant such as NTT862FAE5, reflecting the broader family used for similar 44-channel, 100 GHz C-band operations and documented in vendor-facing configuration guides and product catalogs.
