About This Part
The Alcatel-Lucent 1660 Synchronous Multiplexer (SM) series are core components in legacy and evolving telecommunications networks, primarily functioning within Synchronous Digital Hierarchy (SDH) or Synchronous Optical NETwork (SONET) infrastructures. These systems are designed for efficient multiplexing, demultiplexing, and cross-connecting various digital signals, ensuring robust data and voice transmission over optical fiber. The P21E1 designation likely indicates a specific interface card or module designed to handle E1 (2.048 Mbps) digital streams, which are standard in many parts of the world for carrying voice and data traffic. In telecom and data centre environments, the 1660SM P21E1 module would typically be deployed in central offices, points of presence (PoPs), or enterprise network hubs. Its primary role is to aggregate and transport E1 circuits over an SDH backbone, facilitating services like leased lines, mobile backhaul, and inter-exchange voice connectivity. It ensures high availability and reliable transport for critical communication services, bridging traditional PDH (Plesiochronous Digital Hierarchy) E1 interfaces with modern SDH optical transport. Revo Distribution Limited specializes in providing high-quality used and refurbished telecom and data centre equipment. We carry parts like the Alcatel-Lucent 1660SM P21E1 to support network operators and enterprises maintaining or expanding their existing SDH/SONET infrastructure. Sourcing refurbished equipment from Revo offers a cost-effective solution for extending the lifecycle of established networks, ensuring continued service reliability without the significant capital expenditure of new deployments. Our rigorous testing ensures these parts meet operational standards.
