Nortel NTK503AA (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTK503AA is a 19-inch vMSP (virtual Multiplex Section Protection) optical cage assembly for the OME 6500 shelf, the mechanical housing that holds the pluggable optics used in a protected multiplex-section configuration, where traffic can switch between a working and protection optical path without a service interruption. It is part of the same NTK503-prefix family as this catalogue’s confirmed OME 6500 Converged 40G optical shelf, sized for 19-inch rack mounting. Confirm the exact shelf variant and protection scheme in use before ordering, since cage assemblies are matched to a specific shelf build. The OME 6500 remains a widely deployed DWDM transport platform and mechanical assemblies like this are ordered to keep an existing shelf’s exact configuration intact.
