Verizon has achieved performance of approximately 1 Gbps to a customer on its currently deployed GPON FiOS infrastructure. 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 successfully demonstrated the ability to serve customers on the FiOS network with Gigabit Ethernet (GigE) service.
Verizon said its latest field trial was conducted in June in Taunton, using an existing GPON system developed by Motorola, a current supplier to Verizon of both BPON and GPON equipment. 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.
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 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," said Vincent O'Byrne, director of Verizon's technology organization, who managed the trial.

- In June 2010, Verizon has completed a field trial of a second XG-PON fiber-optic distribution system connecting at 10 Gbps downstream and 2.5 Gbps upstream to a FiOS customer location in Taunton, Mass. The test, which was completed in May, used an XG-PON system developed by Motorola.
The field test used Motorola equipment deployed with dual fibers from an OLT (optical line terminal) in a Verizon switching facility to a combiner that coupled the XG-PON system with the existing GPON system. On the customer-facing side of the network, the test data traveled over a single FiOS fiber link to the customer test location.
At the customer's home, the optical network terminal (ONT) received the 10/2.5 Gbps feed and used two data communication ports to simultaneously provide transmission speeds of close to 1 Gbps to each of two PCs inside the home. Combined, the two ports delivered approximately 1.85 Gbps in aggregate bandwidth in each direction. In addition, speed tests were performed to Verizon's speed test server located more than 400 miles away in Reston, Va., realized speeds of up to 915 Mbps between the PC and the speed test server.
