ADTRAN Develops Frequency Division Vectoring

ADTRAN introduced a Frequency Division Vectoring (FDV) technology that enhances the capabilities of both G.fast and VDSL2 vectoring by enabling them to better coexist by working in tandem across a single subscriber line in the service provider’s network. The company said its patent-pending FDV doubles data rates and increases the reach of intermediate-rate services – between 100 Mbps to 1 Gbps – allowing the delivery of cost-effective premium broadband to 80% more subscribers.

FDV expands the addressable market for G.fast by broadening its applicability from Fiber-to-the-Building (FTTB) and Fiber-to-the-distribution points (FTTdp) out to existing street cabinet sites.

“While G.fast and VDSL2 have always been seen as complementary technologies, the limitations of G.fast have been exposed when forced to operate in a VDSL2-compatible mode at higher rates,” said Jeff Heynen, principal analyst, broadband access and pay TV, Infonetics. “As service providers look to build out their G.fast adoption strategies, ADTRAN’s FDV technology has a key performance impact by allowing G.fast and vectored VDSL2 technologies to work in concert to boost performance. Service providers can now maximize a broader market opportunity without wasting unused bandwidth in their networks or prematurely forcing subscribers served by 100Mbps VDSL2 to move to G.fast.”
