Concentration Switches - LE-327/427 (CN 3940)

Ciena’s Ethernet service concentration switches deliver advanced carrier-class services optimised for cost-effective service delivery to residential or business subscribers. They can be configured with fibre or copper physical interfaces, redundant fans and pluggable redundant AC or DC power. The switches implement Ciena’s advanced operating system (SAOS) – the leading software infrastructure for resilient, flexible, and cost effective Ethernet Access in Metro networks and business LANs.

Supporting distribution of any combination of voice, video, or data services to network subscribers, Ciena’s service concentration switches provide large-scale 100 Mbps and 1 Gbps Ethernet switching that maximises revenue generation potential, while reducing initial deployment costs and minimising ongoing operating costs.

Advanced hardware design combined with the comprehensive features in the operating system enable Ciena’s service concentration switches to be configured as powerful aggregation devices to concentrate and integrate Ethernet traffic from edge devices.
