Ciena NTK589BAE6 50GHz DWDM Optical Transceiver

The Ciena NTK589BAE6 is a Multirate 50 GHz DWDM XFP transceiver that delivers 10GBASE-DWDM throughput over fiber by operating in the 1530.33 to 1533.07 nm window and aligning to a fixed 50 GHz ITU grid. As an XFP-form factor module, it is designed for insertion into DWDM-capable network equipment that supports 10 Gb/s DWDM interfaces, enabling flexible channel plans without replacing entire line systems. It is used to build high-capacity DWDM links across metro, regional, and backbone networks and is suitable for interconnecting network nodes or data-center WAN links that require precise wavelength control and multirate support. The 50 GHz channel spacing and defined wavelength range help ensure compatibility with corresponding DWDM filters, multiplexers, and ROADMs on the ITU grid. When deploying the NTK589BAE6, verify compatibility with your host chassis and management interface to ensure proper operation and visibility within the network's optical layer. This part sits within Ciena's multirate XFP lineup, offering a compact, standards-based solution for expanding DWDM capacity on existing 10 Gb/s paths.
