Product Overview: The 1660SM is a member of the Alcatel OMSN (Optical Multi-Service Node) product series. It serves as a synchronous multi-service aggregation node multiplexing device, primarily positioned in the access layer and aggregation layer of optical transmission networks. Its access ports are compatible with PDH (Plesiochronous Digital Hierarchy) and SDH (Synchronous Digital Hierarchy) ports, including 2M, 34M/45M PDH ports, as well as STM-1, STM-4, STM-16 optical ports and STM-1 electrical ports.
Cross-Connection Capability: For the full high-order path cross-connection of VC4 (Virtual Container 4), the equivalent cross-connection capacity of its cross-connection matrix is 96×96 STM-1. For the low-order path cross-connection matrix including VC12/3 (Virtual Container 12/3), the equivalent cross-connection capacity consists of 64×64 STM-1 low-order path cross-connection and 32×32 high-order path cross-connection.
Product Features:
- Hardware sharing: Service port boards can be shared across the entire OMSN product series.
- Future-oriented network upgrade capability.
- Adopts a node architecture with flexible configuration and powerful functions, supporting various network topologies.
- Possesses strong cross-connection capability, providing both high-order and low-order cross-connections.
- High integration, high flexibility, and low power consumption; the subrack complies with ETSI (European Telecommunications Standards Institute) standards, with all cables routed from the front.
- Features the industry-leading Integrated Service Adapter (ISA), optimized for data services.
- Can be uniformly managed by Alcatel's powerful transmission network management system.
Technical Manual: The Technical Manual for ALCATEL OPTINEX M1660SM 2.5G Multi-Service Transmission Equipment provides detailed information on the advantages, applications, general description, functional description, and physical description of the 1660SM. It can be accessed on Docin.com.
