VDSL2 networks took another step forward as ADTRAN (Nasdaq: ADTN), Alcatel-Lucent (NYSE: ALU) and 13 other vendors recently met at the University of New Hampshire InterOperability Laboratory (UNH-IOL) in Durham, N.H. to conduct interoperability testing of the ITU-T G.vector standard.
Other participating vendors included Actiontec Electronics, AVM GmbH, Broadcom, Calix (NYSE: CALX), Cisco (Nasdaq: CSCO), EXFO, Ikanos, JDSU, Lantiq, Metanoia Communications, NETGEAR (Nasdaq: NTGR), Real Communications and Technicolor.
As more service providers deploy VDSL2 over their existing copper-based networks, G.vector can enhance rate and reach by cancelling crosstalk in real-time between copper pairs in the last mile network.
Although the Broadband Forum did not reveal the results of this plugfest, they did say that the next G.vector interoperability event will take place next month at the UNH-IOL facility.
Over the past year, there has been considerable activity by both U.S. and European providers rolling out, or putting in plans to roll out, VDSL2 with bonding and other techniques such as vectoring.
In the U.S., telcos like AT&T (NYSE: T) and TDS Telecom (NYSE: TDS) have expressed interest in augmenting their VDSL2 deployments with vectoring.
However, European service providers including Belgacom, TDC Denmark, Telekom Austria and Türk Telekom are taking the lead with various deployments and trials. One of the most highly anticipated deployments of VDSL2 and vectoring will take place at Deutsche Telekom (DTE.DE), which announced last December that it would spend €6 billion ($7.9 billion) to build a FTTC network to expand download speeds on its copper lines from 50 to 100 Mbps.
