About This Part
The Nokia 1660/1662 ES1-8FX is a critical interface module designed for the Nokia (formerly Alcatel-Lucent) 1660 SM and 1662 SM Synchronous Multiplexer platforms. These platforms are integral components of Synchronous Digital Hierarchy (SDH) optical transport networks. This specific module likely provides Ethernet service interfaces, enabling the aggregation and transport of Fast Ethernet (100 Mbps) traffic over the underlying SDH infrastructure. It bridges the gap between packet-based Ethernet services and time-division multiplexing (TDM) based optical networks. In a typical deployment, the ES1-8FX card would be utilized by telecommunication carriers and large enterprises to deliver managed Ethernet services to business customers, connect local area networks (LANs) across geographically dispersed sites, or backhaul mobile traffic. Its function is to map Ethernet frames into SDH containers for efficient and reliable transmission over long distances. While specific port configurations and exact throughput depend on the module's variant, the "8FX" designation strongly suggests eight Fast Ethernet ports. Revo Distribution Limited specializes in supplying high-quality, pre-owned telecom and data centre equipment. The Nokia 1660/1662 platforms, including modules like the ES1-8FX, remain widely deployed in operational networks globally. By offering refurbished units, Revo enables network operators to extend the lifespan of their existing infrastructure, reduce capital expenditure on network expansions or replacements, and maintain critical spare parts inventory without compromising performance or reliability. This part represents a cost-effective solution for maintaining and upgrading legacy SDH networks.
