BOSTON-- The cable industry is working to embrace software defined networking (SDN) and network function virtualization (NFV), but the transition will require a significant amount of work.
A top Adtran executive confirmed that the provider is currently engaged in over 60 G.fast trials with multiple service providers.
Adtran says that despite a small dip in first quarter 2016 revenues it is seeing potential revenue opportunities from service provider customers, creating a new future revenue foundation.
The next-generation passive optical networking movement took another step forward this week as the ITU-T has approved the G.989 series of standards for 40 Gbps-capable passive optical networks (NG-PON2).
Service providers' adoption of PON technologies for FTTH deployments drove up the overall broadband access market in 2015 to $12 billion, says Dell'Oro Group in a new report. Due to strong deployments in China, particularly in CPE, PON revenue from three manufacturers-- Huawei, ZTE and Alcatel-Lucent-- grew by 21 percent to over $6 billion in 2015.
As Tier 1 telcos move forward with their G.fast plans, the real test will be when these carriers roll out service on a broader scale beyond the lab and limited field trials being conducted today.
BT may be one of the early providers to go public about G.fast trials for consumers, but its recent lab trial to deliver a Cloud Radio Access Network (C-RAN) cellular network service over copper shows that the technology has other potential uses.
AT&T's interest in using G.fast as a way to extend broadband services where it can't build a business case to bring fiber directly to a home could spell opportunity for Adtran, one of the telco's key broadband infrastructure suppliers.
BT is on track with its G.fast trials, serving its own customers and eight of its competitive carrier provider customers via its Openreach division. But the service provider is still weighing how it can make an investment case for a broader deployment.
BT has confirmed that it is testing Adtran's 500G fiber-to-the-distribution-point (FTTdp) platform as part of its G.fast trial taking place in over 2,000 premises in Huntingdon, Cambridgeshire.
