AUGUST 16, 2010 -- Verizon has completed a field trial in which it delivered approximately 1-Gbps bandwidth to a customer on the currently deployed gigabit passive optical network (GPON) in a live production FiOS network setting.
Verizon's GPON platform supports a total throughput of 2.4 Gbps downstream and 1.2 Gbps upstream to customers connected to the PON. This test demonstrated the ability to serve customers on the FiOS network with Gigabit Ethernet (GigE) service.
The latest field trial was conducted in June in Taunton, Mass., using an existing GPON system developed by Motorola, a current supplier of BPON (broadband passive optical network) and GPON equipment to Verizon. The trial, conducted at an existing FiOS business customer location, was intended to demonstrate in a live network setting that currently deployed FiOS equipment can support higher bandwidth services and can deliver 1 Gbps without major change to the network.
"This kind of bandwidth capacity will provide Verizon the ability to continue to meet FiOS customers' needs by offering more bandwidth to support services such as 3DTV, ultra HDTV, multiplayer gaming, and HD video conferencing," says Brian Whitton, executive director of Verizon's technology group.
The test involved bringing a new fiber connection from an existing operating GPON system at the company's Taunton call-switching office to a second optical network terminal (ONT) located at the 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 (megabits per second) 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 this 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," explains Vincent O'Byrne, director of Verizon's technology organization, who managed the trial.
