The Ciena NTK535LB is an OME 6500 4-Port Gigabit Ethernet line card that delivers four 1 Gbps Ethernet interfaces via SFP sockets. As a member of the OME 6500 family, it plugs into the modular line-card ecosystem to extend Ethernet access toward the edge in metro deployments, enabling tailored connectivity at the customer edge. Identified by the WMOTBRFJAA variant code, the NTK535LB is described in listings as a GE EPL 4-port SFP card. This card is designed for installation in Ciena/Nortel 6500 shelves and should be deployed with other 6500 line cards in a compatible chassis, power, and backplane.
