Ciena NTT862BAE5 Mux-Demux 50GHz C-Band Module

The NTT862BAE5 is a 44-channel Mux/Demux (CMD44) module engineered for the C-band with 50 GHz channel spacing. Listed in vendor catalogs as the blue CMD44 module, it is designed to multiplex and demultiplex 44 optical channels across the C-band, enabling flexible, fixed-grid DWDM configurations. This module is part of Ciena's 6500 Photonics family and is intended for integration with Ciena's long-haul switching and multiplexing hardware, supporting compact, high-density WDM multiplexing within the OM6500 platform. The NTT862BAE5 CMD44 module's 44-channel, 50 GHz C-band configuration makes it suitable for networks requiring dense channel counts and precise fixed-grid spectral allocation in metropolitan and inter-city DWDM deployments.
