Verizon teased the long-term future of its FiOS service today by confirming that it's the first to test a new form of passive fiber optic network that could dramatically increase the practical speeds of its Internet access. Called XG-PON, the test service has been shown running through a test FiOS home at up to 10Gbps downstream, or about four times faster than the existing 2.5Gbps infrastructure. Uploads are about twice as fast at 2.4Gbps versus 1.24Gbps on today's hardware.
