Verizon Demonstrates 1 Gbps Throughput on Existing FiOS Network

WALTHAM, MA – Not to be outdone by Google, Verizon has completed a field trial in which it delivered close to 1 Gbps bandwidth to a customer on its existing FiOS network. The company says this kind of capacity and versatility will help it accommodate new services such as 3DTV, ultra HDTV, multiplayer gaming, HD video conferencing, desktop virtualization and remote storage, as well as wireless backhaul for the next generation of wireless technologies.

The GPON platform that Verizon uses for FiOS supports a total throughput of 2.4 Gbps downstream and 1.2 Gbps upstream. This test demonstrated that individual FiOS customers can get Gigabit Ethernet (GigE) service. However, because the total GPON bandwidth is normally shared by as many as 32 customers, if all FiOS customers try to use 1 Gbps bandwidth at the same time (an unlikely scenario in the near-term future), the system will not meet the demand - which is why Verizon is also testing the next generation of FTTH equipment.

The latest field trial was conducted in June in Taunton, using an existing GPON system developed by Motorola, which supplies both BPON and GPON networking equipment to Verizon. The test involved bringing a new fiber connection from an operating GPON system at the company's Taunton call-switching office to a second optical network terminal (ONT) at a business customer's facility. The second ONT was provisioned for the new 1 Gbps service tier, and the speed was tested to a local speed test server over an optimized route, as well as across the public Internet to a regional speed test server located more than 400 miles away.

The throughput speeds were measured at 925 Mbps to a local server and more than 800 Mbps to the regional test speed servers. The customer's existing FiOS service was left in place, and showed no degradation in the voice, data or video services during the trial.

"This trial demonstrated that the current architecture has sufficient headroom to allow for a progressive increase in capacity as needed by our residential and business customers on our current GPON platform, and validates our decision to support both residential and business services on the same platform," said Vincent O'Byrne, director of Verizon's technology organization, who managed the trial.
