Deutsche Giga Access taps Adtran for FTTH

network controller supports ultra-short micro-release schedules which speed time-to-market. This enables DGA to lower its cost to build, operate, innovate and maintain its network compared to its legacy solutions. Adtran also enabled DGA to deliver proactive support and services from an open, cloud-based platform for greater adaptability, security and updates at scale. As a result, the company says, DGA can reduce support tickets and improve customer satisfaction.

Deutsche Giga Access GmbH (DGA) has selected the Adtran’s SDX Series of fibre access platforms to offer its customers scalable FTTH service capabilities. Adtran says its Combo PON technology and the software-defined architecture were differentiators that provided DGA a path to market. They also provided DGA with the flexibility to simultaneously operate 1G and 10G FTTH networks on the same point-to-multipoint, fibre optic distribution network from a single OLT port. The Adtran SDN-based

area in Lower Saxony (Niedersachsen), Germany, and Adtran provided the right combination of technology, products, local support and domain experience,” said Andreas Bamberg, chief technology officer at Deutsche Giga Access GmbH. “We chose Adtran because its approach allowed us to build a new, open-access wholesale network for future- proof services that can be controlled by an end-to-end automatization management system, providing tremendous operational savings and efficiencies as demand for our wholesale offering grows.”

DGA, a regional wholesale access provider in Germany, will help service providers connect homes and businesses with modern broadband service in selected regions across the country. DGA will be doing its part to meet Europe’s digital agenda objectives ensuring fair, open and secure digital environments that will create the right conditions for digital networks and services to flourish and maximise the digital economy’s growth potential. “DGA wanted to quickly deploy a Gigabit-capable FTTH network to a new

resistance to hydrogen penetration, an element which is unfavourable to the operation of optical fibre in ocean waters. The end-to-end system also features an unrepeatered subsea segment in the Irish Sea, a terrestrial segment in the UK and a repeatered segment in the North Sea. Typical systems have one or two of these elements, but not all three. The system used an enhanced, jet-assisted burial plough in the North and Irish Sea segments, allowing installers to bury the cable to specific depths in very challenging seabed conditions. Meta says, “Subsea cables are part of our continued efforts to invest in foundational infrastructure to keep up with demand for the internet now, and build for the metaverse in the future. We know bringing the metaverse to life will require major advances in underlying connectivity infrastructure.”

Aqua Comms, Bulk Fibre, Alcatel Submarine Networks (ASN) and Meta, have announced the completion the construction of the Havhingsten cable system, which runs across the Irish Sea from the north of Dublin, in the Republic of Ireland, to south of Blackpool on the west coast of the UK, with a section also linking into the Isle of Man, and from Seaton Sluice in Northumberland to Denmark. The partners say the Havhingsten cable system boasts several innovations in its design and construction and is the world’s first aluminium conductor powered subsea cable system. The removal of traditional copper raw material, and replacement with aluminium from the manufacturing process, improves efficiency and cost reduction, as copper is associated with variable availability and higher price. Additional benefits include improved

Utilising its ICE technology, Infinera has raised fibre capacity for international CSP PCCW Global and German data centre operator and web host Hetzner Online. The deployment by PCCW is on the PEACE subsea cable system between Marsei lle, Cyprus and Abu Talat. Uti l ising Infinera’s ICE technology, PCCW Global now offers network operators the abi l ity to increase capacity per fibre pair on its Middle East and Mediterranean fibre routes. Infinera says that by leveraging its ICE technology on the GX Series Compact Modular Platform, PCCW Global is able to reach individual wavelength speeds of 650Gbs resulting in more capacity, with less hardware, and providing

up to 25 terabits per fibre pair, meaning network operators can provide high-capacity services between the Middle East and the Mediterranean region. The capacity upgrade on the PEACE cable system is one of a series of upgrades planned for this year. As the first and only open cable system in the Mediterranean Sea, the PEACE cable system can support numerous service providers in the region.
