Description:
The Nortel NTCA36BC is an optical line card module used in Nortel optical transport systems designed to handle multiple OC‑12 (optical) or STM‑4 (SDH) tributary interfaces. It provides four independent transmit/receive channels for OC‑12/STM‑4 level signals at short optical reach (typically 1310 nm wavelength). This card integrates into a modular optical transport chassis where it handles four lower‑order optical interfaces for aggregation into higher‑order transport streams.
