Description
The Ciena NTK539PCE5 is a 40 G OCLD (Optical Coherent Line Deck) circuit pack designed for the Ciena 6500 Packet-Optical Platform. It implements a 40 G coherent optical line interface using eDC40 OTU3+ technology, providing high-capacity optical transmission over DWDM fiber links. This circuit pack supports advanced forward error correction and dual-polarization modulation for robust optical transport.
Circuit packs in the NTK539PxxE5 family handle coherent optical line functions within the 6500 shelf, enabling metro and long-haul optical connections using 40 G coherent protocols.
