Alcatel 3AL78821BAAA P4S1N Module for optical network transmission systems.

The Alcatel 3AL78821BAAA is a P4S1N module designed for deployment within Alcatel-Lucent optical transmission and transport network infrastructure. This module provides interface connectivity for STM-1 level traffic, supporting synchronous digital hierarchy (SDH) network architectures.

The P4S1N module is typically utilised within Alcatel’s optical networking platforms, providing tributary or aggregate interfaces for carrier-grade telecommunications networks. It enables operators to deliver reliable, high-capacity transport services across metro and regional network deployments.

This is a legacy module associated with Alcatel-Lucent’s earlier generation of optical transport equipment. Whilst no longer in active production, these modules remain in demand for maintaining and extending existing network installations where operators continue to run SDH-based infrastructure.
