Description
The Alcatel‑Lucent 3AL78894CA is an optical port interface board designed for use in the Alcatel‑Lucent 1660SM / 1662SM synchronous multiplexer series and similar platforms. It is identified in parts lists as an S‑16.1ND port board, meaning it provides a 16‑channel optical interface and sub‑module for that slot type. The board supports optical connections via FC/PC connectors and integrates with the system backplane for handling optical transport signals.
The designation S‑16.1ND refers to the specific port type and configuration — typically a set of optical interfaces organized in a 16‑channel format to deliver or receive synchronous transport signals on the 1660SM system.
This part is sourced under the Alcatel‑Lucent name and is used in legacy telecom optical transport equipment where precise optical input/output port functionality is required.
