Nortel NTK503ADE5 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTK503ADE5 is an OME 6500 Converged 40G Optical Shelf, the physical shelf/chassis for Nortel’s OME 6500 multiservice optical edge platform configured for 40Gbps aggregate optical throughput. The shelf houses the OME 6500’s shelf processor, tributary, aggregate and cross-connect cards, and the Converged 40G designation identifies this shelf variant’s backplane/optical-interconnect capacity rather than a single card’s function. Tech-Star supplies this as a secondary-market unit for engineers building out or replacing an existing OME 6500 shelf. Shelves of this size are typically deployed at metro or regional aggregation points rather than at the network edge, where the additional 40G of aggregate capacity supports a larger number of tributary and DWDM aggregate cards fitted into the same frame.
