Adtran announce Frequency Division Vectoring

Adtran, a provider of next-generation networking solutions, has announced a new technology - Frequency Division Vectoring (FDV) - that has the potential to eliminate several key barriers service providers face when expanding broadband service deployments.

Adtran’s FDV solution 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.

This new patent-pending technology enables service providers to take immediate advantage of the maximum G.fast performance without the expense of transitioning an entire subscriber base from VDSL2 to G.fast technology.

This announcement comes hot on the heels of Bell Labs (Alcatel Lucent) broadband speed record of 10 Gbps using traditional copper telephone lines – by employing a new technology called XG-FAST. This new announcement from Adtran further strengthens the position of service providers that utilise copper access networks to provide next generation broadband services. This is a positive step for consumers who want to take advantage of symmetrical broadband services, but live in areas where FTTH rollouts have not been completed.

‘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 maximise a broader market opportunity without wasting unused bandwidth in their networks or prematurely forcing subscribers served by 100Mbps VDSL2 to move to G.fast.’

FDV expands the addressable market for G.fast by broadening its applicability from Fibre-to-the-Building (FTTB) and Fibre-to-the-distribution points (FTTdp) out to existing street cabinet sites. This allows service providers to fortify recent cabinet investments while mitigating the operational challenges that currently exist regarding providing power to new FTTdp deployments. FDV strengthens the value proposition of G.fast by substantially improving deployment economics and enabling faster service time to market for game-changing broadband services rates.

This technology preserves investments already made in Fibre-to-the-Cabinet (FTTC) type infrastructures, allowing service providers to compete with FTTH style deployments for longer without upgrading the last mile, which is the most costly and time consuming.

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 per cent more subscribers.

‘ADTRAN is the trusted technology partner for service providers around the world because we enable them to address real-world pain points in their network deployments. Frequency Division Vectoring is the latest example of the breakthrough solutions we bring to our customers,’ said Dr Kevin Schneider, chief technology officer, ADTRAN. ‘FDV allows service providers to expand the capacity of their Fibre-to-the-Cabinet architecture to Fibre-to-the-Distribution Point levels without a deeper investment into their fibre infrastructure. This will enable service providers to cost-effectively accelerate premium broadband services for their entire subscriber base.’
