XO Communications has selected Ciena’s CN 4200 FlexSelect Advanced Services Platform to support the delivery of its optical metro transport services. 
- In January 2008, Ciena announced new G10 and G10X Ethernet Service Modules that deliver Layer 2 Ethernet aggregation, switching and transport capabilities on to the company’s CN 4200 FlexSelect Advanced Services Platform family. Targeted applications for the CN 4200 with new Layer 2 Ethernet aggregation and switching capabilities include Metro Ethernet Forum-based Carrier Ethernet services, broadband aggregation for triple play and IPTV services and 3G wireless backhaul.
- Ciena’s CN 4200 is a WDM transport platform that offers on-demand programmability and support for any service. The CN 4200 platform allows network operators to groom, switch, and transpond a diverse range of client services, such as OC-3/12/48 and STM-1/4/16, GbE, Fibre Channel, FICON, and ESCON into higher-speed 2.7 Gbps (OTU-1), 10.7 Gbps (OTU-2), and 43 Gbps (OTU-3) transport streams. In addition, an “RS” chassis can function as a multi-degree Reconfigurable Optical Add/Drop Multiplexer (ROADM).
