XO Selects Ciena for Nationwide Ethernet Hubs

XO Communications has deployed Ciena's Carrier Ethernet Service Delivery Switches throughout its metropolitan networks as part of its new Ethernet Hub service, which provides a scalable way for domestic and international carriers to expand the reach of their Ethernet services in the United States.


XO has approximately one million miles of metro fiber networks in major markets across the United States and serves 75 metropolitan markets. The new XO Ethernet Hub service offers dedicated access to its extensive Ethernet footprint, including its Ethernet over Copper footprint serving more than 3.7 million buildings. The service offers a variety of Ethernet bandwidth options ranging from 5 Mbps to 10 Gbps and key Ethernet features, including 802.1Q, VLAN stacking and jumbo frames.


Specifically, XO is deploying Ciena's LE-311v Service Delivery Switch in all metro markets to provide the Ethernet Network-to-Network Interface (ENNI) function of the Ethernet Hub service -- identifying, separating and tagging different traffic types, aggregating the traffic for hand-off to XO's core network and switching the traffic across the network with the appropriate class-of-service, security and rate-limits in a point-to-multipoint architecture. Financial terms were not disclosed.http://www.xo.com

  • In September 2008, Ciena announced that XO had selected its CN 4200 FlexSelect Advanced Services Platform to support the delivery of its optical metro transport services. XO Communications will utilize Ciena's CN 4200 in its metro networks nationwide to support the aggregation and transport of high-capacity services. In addition, XO Communications is now a designated Managed Services Provider (MSP) partner within Ciena's BizConnect global partner program.


  • 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.
