3HE04166AAAC02 ALCATEL Alcatel-Lucent 7450 ESS System Module

The Alcatel 3HE04166AAAC02 is a Switch Fabric Module (SFM3-7) designed for the Alcatel-Lucent 7450 Ethernet Service Switch (ESS) platform. This module provides the internal switching fabric that enables high-speed data forwarding between line cards within the chassis, serving as a critical component of the system’s packet processing architecture.

The 7450 ESS is a carrier-grade Ethernet service router designed for metro Ethernet and business service aggregation networks. The SFM3-7 switch fabric module is essential for maintaining the throughput and performance capabilities of the chassis, ensuring non-blocking switching capacity across installed interface modules.

The 7450 ESS platform has been widely deployed by service providers and large enterprises for delivering managed Ethernet services. While this platform represents an established generation of Alcatel-Lucent routing technology, it remains in active use across many production networks requiring reliable spare components for maintenance and expansion.
