Adtran’s G.fast gear on trial at more than 60 telcos

By Charles Hall

Alabama-based Adtran has become a global leader in supplying equipment for deploying fiber networks, both to the home and to the neighborhood or MDU, as well as allowing copper wire-bound telcos to upgrade those to the kinds of speeds consumers want in 2016 and beyond. And those consumers are worldwide as shown by Adtran’s latest announcement.

The Israeli incumbent telco Bezeq Israeli Telecommunication has been using Adtran’s G.fast gear in field trials in one of Israel’s largest, but unnamed, cities. The trial involves different copper loop lengths and their impact on broadband speeds over Adtran’s G.fast architecture, which allows telcos to specify their G.fast chipmaker and the number ports for each DPU (Distribution Point Unit) where fiber and copper to the residence connect, also called port density. This enables telcos such as Bezeq to plan how they will exploit their existing infrastructure to deliver much faster speeds than traditional copper wire VDSL broadband technologies.

Bezeq is currently trialing the 8-port and 16-port Adtran DPUs that are both physical layer and chipset agnostic. Bezeq is the largest telco in Israel and has pilots of G.fast in Modiin now and is expected to expand it to Haifa, Rishon Lezion, Sderot, Tel Aviv, Ganei Tikva and Tur’an. Bezeq and its subsidiaries offer the complete range of services, including wireline and cellular broadband and telephony, plus pay TV.

The trials are in anticipation of Bezeq beginning to upgrade much of its broadband network to 200-300 Mbps with G.fast and other parts to FTTP to some subscribers and buildings throughout Israel in early 2017. The decision to deploy G.fast or all-fiber will be based on economic considerations. It’s a hybrid approach that most telcos worldwide are adopting – all-fiber where it makes economic sense and G.fast where it doesn’t justify investing in building all-fiber networks.

Adtran said its 500G G.fast products series is exceeding expectations in trials at more than 60 telcos worldwide and that it provides longer reach and faster speeds.

Adtran’s G.fast solutions use SDN principles to ensure rapid plug and play capability within multi-vendor FTTx infrastructures. It collaborates with standards bodies such as the Broadband Forum to create open APIs and interfaces that accelerate network integration, avoiding vendor lock-in and liberating telcos in their procurement decisions. Adtran said its range of G.fast based product offerings allow telcos to benefit from the fastest possible time to market for the next wave of ultrafast broadband services by repurposing existing cabinet locations.

Bezeq CTIO Yaki Zano said, “our trials have proven G.fast to be both an innovative and a pragmatic broadband technology that creates new possibilities thanks to its flexible deployment capabilities. We are pleased that Adtran has enabled us to accelerate the delivery of new transformative Gigabit broadband services.”

Dr Eduard Scheiterer, SVP for research and development at Adtran, said, “Bezeq is committed to delivering infrastructure for a Gigabit society, and it’s clear how G.fast will play a vital role in accomplishing this for many areas throughout Israel, alongside traditional FTTP approaches where required. The path to delivering transformative broadband is made even more compelling as FTTC deployment models are supported with an increase in G.fast equipment port density and enhanced G.fast chipset performance, permitting substantial asset reuse and accelerating the pace of rollout.”
