ADTRAN today announced Frequency Division Vectoring (FDV), its patent-pending technology, to enhance the capabilities of both G.fast and VDSL2 vectoring and assist broadband telecom operators.
There are three important benefits.
First, service providers can maximize market opportunities.
Second, they can optimize bandwidth in their networks.
Third, telecoms will be from forcing subscribers served by 100Mbps VDSL2 to move to G.fast.
The new technology from ADTRAN enables both G.fast and VDSL2 vectoring to coexist by working in tandem across a single subscriber line in the service provider’s network, thereby avoiding key issues faced by broadband service providers.
ADTRAN says the new technology enables telecoms to benefit from the G.fast performance without transitioning subscriber base from VDSL2 to G.fast technology.
In addition to preserve investments in Fiber-to-the-Cabinet (FTTC) infrastructure, 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 percent more subscribers, said ADTRAN in a statement.
Jeff Heynen, principal analyst, broadband access and pay TV, Infonetics, said: “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.”
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. This apart, FDV strengthens G.fast by substantially improving deployment economics and enabling faster service time to market for game-changing broadband services rates.
Kevin Schneider, chief technology officer, ADTRAN, said: “FDV allows service providers to expand the capacity of their Fiber-to-the-Cabinet architecture to Fiber-to-the-Distribution Point levels without a deeper investment into their fiber infrastructure. This will enable service providers to cost-effectively accelerate premium broadband services for their entire subscriber base.”
