Description:
The Nortel NTCA04NT is a legacy optical transport interface module originally manufactured by Nortel Networks for use in high-speed optical networking systems. It is included among the NTCA04 family of optical cards — which span regenerators, transmitters, and receivers for OC-192 / STM-64 DWDM fiber transport. These modules were designed for modular optical transport chassis where they provided high-capacity optical interfaces for backbone and metro DWDM networks. Although detailed official datasheets for the NTCA04NT variant itself are limited in publicly available sources, the presence of the part in legacy telecom inventory lists with other NTCA04 optics confirms that it is an OEM optical interface card offered by Nortel and stocked by aftermarket parts distributors for network maintenance and refurbishment.
