Alcatel-Lucent P4S1N 4x STM-1 optical/electrical port card for the 1660 SM multiplexer.

The Alcatel-Lucent P4S1N (3AL78821BAAF01) is a 4x STM-1 optical/electrical port card for the Alcatel-Lucent 1660 SM optical multiplexer, a synchronous digital hierarchy (SDH) cross-connect and add/drop multiplexer platform used at STM-1/4/16/64 levels in enterprise, metro, regional and backbone transport networks with integrated packet-switching capability.

The P4S1N provides four STM-1 (155 Mbit/s) tributary or aggregate ports on a single card, giving the 1660 SM the interface density needed to add, drop or cross-connect SDH traffic at that rate, and slots into the multiplexer’s subrack alongside other optical and electrical tributary cards. As one of the standard interface options for the 1660 SM, the P4S1N was widely deployed by network operators building and maintaining SDH transport rings through the 2000s and 2010s.

Tech-Star supplies the P4S1N as a genuine like-for-like spare for operators and integrators keeping 1660 SM-based transport networks running. Tech-Star (UK-based, shipped worldwide) – contact us to confirm the exact card revision and compatibility with your system.
