Verizon has successfully tested pre-standard XG-PON2 technology capable of delivering a 10 Gbps connection both downstream and upstream. 
The tests were conducted at a customer's business in Taunton, Mass., using the same optical fiber that provides that business with its existing FiOS network connection. None of the FiOS TV connections were affected by the trial, and there was no impairment to the business customer's data service as the GPON and XG-PON2 signals were layered over the same fiber for the trial.
The XG-PON2 trial used a prototype system developed by Alcatel-Lucent, which provides a GPON system used by Verizon, and implemented using the same wavelengths that were standardized for an earlier version of the XG-PON technology. The optical network terminal (ONT) unit placed at the business-customer location supported up to 10 single GigE links, as well as one dedicated link capable of delivering the full 10 Gbps symmetric speeds to a single location. Two PCs, each having a 10 Gbps network interface card, were communicating across the network between the ONT and the line terminal equipment located in the Verizon switching facility in Taunton.
"This trial demonstrates the capacity of Verizon's FiOS network to provide even greater upstream bandwidth capabilities required for adoption on a mass scale of new and emerging residential applications like user-generated video, as well as business services," said Brian Whitton, executive director of technology for Verizon. "High-definition video sharing, 3-D video, video telephony, telemedicine, and offsite backups and storage services are just a few of the applications that will take advantage of the expanded capacity Verizon is demonstrating today."http://www.verizon.com
- In May 2010, Verizon 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, 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.
- In December 2009, Verizon announced its first field-tests of XG-PON. XG-PON signal was tested independently on a dedicated passive optical network (PON) as well as overlaid on a fiber providing FiOS service to a customer. This test used XG-PON equipment from Huawei.
