Nortel NTCA05BA OC-192 / STM-64 optical DEMUX card.
The Nortel NTCA05BA is an OC-192/STM-64 DEMUX card, an optical demultiplexer module for Nortel’s high-speed optical transmission platform.
The card demultiplexes an OC-192 (9.95 Gbit/s SONET) or equivalent STM-64 (SDH) optical signal, separating the aggregate high-speed line signal back into its constituent channels or tributaries for further processing within the transmission shelf. It belongs to the same NTCA card family as the NTCA42BA maintenance interface and NTCA10AA DWDM coupler used on related Nortel optical platforms.
The NTCA05BA is specific to Nortel’s OC-192/STM-64 optical transmission equipment. Tech-Star (UK-based, shipped worldwide) checks every card before it ships. Get in touch to confirm compatibility with your optical transport shelf.
