HUNTSVILLE, Ala. - (August 10, 2020)— Adtran®, Inc., (NASDAQ: ADTN), the leading provider of next-generation multi-gigabit fiber access and fiber extension solutions, today announced that TPG Telecom Group (TPG) is leveraging the Adtran second generation Gigabit Gfast fiber extension portfolio to upgrade existing broadband services to Gigabit speeds and attract new subscribers. Adtran is enabling TPG to rapidly roll out Gigabit broadband services to more than 230,000 premises and over 2,000 buildings across Eastern Australia.
TPG is Australia’s second-largest telecommunications provider with a large footprint of both single- and multiple-dwelling locations that were connected by VDSL technology. The service provider wanted to offer Gigabit services to these existing subscribers as well as everyone else in its DSL services footprint. TPG is the first major telco in Australia to deploy Gfast and it selected Adtran’s latest Gfast technology to rapidly launch fast, competitive broadband service speeds that are 10 times faster than similar services offered by competitors in the region.
“In today’s global digital economy, having access to Gigabit services is a big competitive advantage for any carrier that wants to offer the best connectivity solutions to residential and business customers. The launch of Gfast has helped us offer some of the fastest broadband speeds available in Australia today and will be a game-changer for TPG’s wholesale business and customers,” said Jonathan Rutherford, Group Executive, Wholesale, Enterprise and Government at TPG Telecom Group. “We’ve been proud to work with Adtran—it has overcome global component supply constraints to ensure we were ab
Since Adtran pioneered XGS-PON, there has been an ongoing industry debate regarding when and where a FTTH network operator should employ fiber broadband services using GPON versus XGS-PON standards. The availability of Combo PON capabilities built into second-generation XGS-PON solutions concludes the debate, as an operator can now leverage both FTTH standards without sacrificing in terms of cost or capability.
As first-generation XGS-PON solution costs have fallen over the last couple of years, XGS-PON electronics have leveled off at about 20 to 30 percent more that 15-year-old GPON electronics. When comparing the entire FTTH network build-out that comes out to only two-to-three percent more capital per home to support the increased capability of symmetrical multi-gigabit PON services.Due to this, almost all greenfield networks today are being built using XGS-PON. Where service providers may balk at the need to deviate from tried-and-true GPON technology are those smaller brownfield GPON networks that demand neither the added network capacity nor the multigigabit service differentiation offered by XGS-PON.
First-generation XGS-PON provided the ability to simultaneously overlay, on the original GPON-powered fiber network, a much higher-capacity FTTH technology. If free space is available within the FTTH platform, CO rack, or cabinet, a new XGS-PON FTTH module and the required external coexistence module could be installed with little consequence, save for the optical budget impact of external coexistence module. More on that later. This XGS-PON overlay would enable the FTTH operator to offer differentiated multigigabit services and considerably increase the network’s capacity to deliver 100Mbps and gigabit services.
Fiber-to-the-Home (FTTH) subscriber connection costs and capabilities have evolved considerably in the last 15 years. Fiber installation techniques such as micro trenching and public-private partnerships leveraging existing right of ways and improved regulatory policies have all helped to reduce FTTH construction costs. Innovations in fiber optics and improvements in fiber connection and distribution methods have reduced the cost to connect an FTTH subscriber from several thousands of dollars per home to as low as a few hundred dollars today. Passive Optical Network (PON) technology innovation, Moore’s Law, and economies of scale have greatly increased capabilities while at the same time reducing the cost of an FTTH connection. The days of $500 ONTs and optics connected to expensive two-port OLTs have given way to $50 ONTs and high-density 16-port OLTs. Fiber access nodes have evolved from supporting dozens of 30Mbps residential services to supporting thousands of 100Mbps and Gigabit residential and business services – all on a single access node. It should be noted that this decade worth of increased FTTH service differentiation or utility has all occurred using Gigabit PON (GPON) and Ethernet PON (EPON) technology paired with innovations in the cost and scale of Ethernet switching, electronics packaging, and pluggable or integrated fiber optics. So how much further can we improve the business case for fiber and how will that occur? Will additional small steps in ONT cost improvement or higher density OLTs be enough to persuade broadband service providers operating within broadband underserved areas to deploy more FTTH or will a bigger step in innovation be required to spur further investment?
