Nortel NTCA70KK (telecommunications transmission and networking portfolio) Optical Transmission Module

The Nortel NTCA70KK is an OC-48 DWDM transponder card tuned to 1552.52nm with an open (client-side) interface, part of the documented NTCA-prefixed transponder family used across Nortel’s OME 6500 and OPTera Metro optical transport platforms. Open-interface transponders take a standard, non-DWDM client signal, in this case at OC-48 (2.5Gbit/s), and convert it onto its assigned ITU DWDM wavelength for transport across the shared fibre, with the 1552.52nm channel corresponding to a different slot on the same ITU wavelength grid as its 1555.75nm sibling. These optical transport shelves remain in service across a number of established metro and regional networks, and genuine transponders tuned to the correct wavelength are needed to restore or expand capacity on a specific DWDM channel. Tech-Star (UK-based, shipped worldwide) stocks Nortel optical transport cards to support ongoing network maintenance.
