IP Network
The core of the XO IP network is a mesh of multiple 10 Gigabit (Gbps) circuits, connecting XO network nodes, peering POPs and XO Data Centers nationwide. The XO IP backbone runs across its own intercity fiber facilities, supported by terabit-capable core routing platforms and high-capacity peering interconnections. XO offers Dedicated Internet Access (DIA) and IP Transit customers enhanced Internet connectivity. This network design delivers maximum end-to-end throughput as well as high levels of protection, redundancy, and Quality of Service required to support XO Voice over IP services.
The XO IP network utilizes an advanced IP design, ensuring scalability as well as the ability to offer advanced future IP services plus the added benefit of no single IP point of failure past the customers' access port.
And since the XO IP network and market connections run end-to-end across XO facilities, XO can quickly resolve any problems that may occur, this eliminates many of the common failure points found in older network designs.
Peering Infrastructure
As one of the few fully peered, facilities-based backbone providers in the U.S., XO has substantial private peering arrangements in many metropolitan areas at speeds of up to 10 Gbps. As a Tier 1 Internet provider, XO is constantly improving its peering infrastructure to benefit our customers. Those advantages include:
- Multiple and geographically redundant dedicated connections to other Tier 1 Internet backbones. Dedicated and private connections mean traffic crosses the XO network and the peering partner's backbone only. Customers benefit because data packets to and from the peering networks reach their end destination quickly and with lower risk of loss.
- XO peering relationships are monitored and maintained 24x7.
- Quality control of the XO network because we don't have to rely on other networks for Internet connectivity.
Connectivity from Internet Access POPs to the XO® backbone
XO currently offers Dedicated Internet Access and Carrier Transit connections via 39 Metro POPs in 31 markets. All DIA markets are connected to the closest XO IP Core Node; dual uplinks are provided from each Metro market into the closest intercity core node at speeds from OC-12c (622 Mbps) to 10 Gigabit Ethernet (10 Gbps).

Metro Fiber Connectivity
Metro Area Networks (MANs) allow XO to control customer traffic and ensure an efficient data transfer to the intercity network. XO® metro-area networks are composed of enough metro fiber-optic cable to circle the globe more than 45 times -- 1.16 million metro fiber miles throughout 40 major US cities, including the largest 30 cities in the United States.
Unlike non-facilities based providers or long-haul providers, XO, with its MANs, has access to the end customer. The MANs enable XO to offer such dynamic products as Ethernet and SONET services that carry data faster and more efficiently than our competition.
The Intercity Fiber Network
XO has deployed a nationwide terabit inter-city transport network using the industry’s most advanced Dense Wavelength Division Multiplexing (DWDM) routing technology. This intercity network spans 18,000 route miles across the continental United States. The extensive reach of the XO fiber network affords XO the unprecedented ability to manage customer data from the point of access to the point of termination. Owning such a vast network facility gives XO the power to:
- scale immediately to meet customer demand
- quickly respond to network issues and
- control prices charged to customers.
