A number of chipset companies recently met at the University of New Hampshire InterOperability Laboratory (UNH-IOL) to perform the first interoperability testing of the ITU-T’s new G.vector specifications.
The G.vector technology provides a boost to VDSL2 subscriber data rates by leveraging new features in the G.vector specification to cancel the crosstalk in real-time between VDSL2 enabled wire pairs in the copper network.
According to the Broadband Forum, removing the effects of the crosstalk noise between wire pairs allows the G.vector equipment to operate at higher bit rates, and will give subscribers quality access to even higher bandwidth services.
Broadcom, Ikanos, Lantiq, Realtek and Triductor participated in the plugfest, providing chipset platforms to test with one another. Telebyte also participated, providing test equipment to simulate the crosstalk of copper networks during the testing.
“This was the first event in a very important journey and we are looking forward to continued progress as the innovative technology is implemented and scaled for deployment,” said Kevin Foster, head of BT’s UK Access Platform Evolution. “Interoperability has always been a key component of successful large-scale deployment of DSL, and we are looking to the Broadband Forum and UNH-IOL labs to lead these testing efforts to allow operators to achieve smooth introduction of DSL innovations such as vectoring.”
The Broadband Forum develops test suites and plugfests on xDSL, next generation fiber access and CPE remote management.
“We see interoperability of these technologies as one of the major driving forces of our member companies,” said Robin Mersh, the organization’s CEO.
