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?

This is the first in a two-part series of articles exploring XGS-PON vs. Active Ethernet. In this article, we will explore why operators must seriously consider ceasing the use of Active Ethernet in their new fiber deployments. The second article will discuss innovative solutions that will enable operators to leverage XGS-PON with any existing Active Ethernet network deployments, thus providing substantial power, space, and equipment cost savings.
The Storied Journey of Fiber Optic Networks
We live in a world where most people are accustomed to the joys of broadband internet, whether it be talking to their TVs, doing group calls with people across the globe, or cultivating virtual lives in cloud-hosted video games where the shackles of reality are left behind. It is absurd to think that less than three decades ago, the World Wide Web was born! The transformational impact on culture, commerce, and technology born from the internet was nothing short of revolutionary! Gigabit speeds are rapidly becoming the norm today. While many contend that users don’t need Gigabit, everyone agrees that this next speed tier is what operators are leveraging to attract customers onto their new fiber networks - Gigabit speeds today with multi-gigabit speeds just around the corner!
While most internet early adopters leveraged ‘twisted copper pairs’ used for analog telephony as dial-up internet access mechanisms, the internet truly began its journey toward democratization with the emergence of “always-on” Digital Subscriber Lines (DSL). DSL became the de facto telco technology to bring internet to homes and businesses. While cable TV companies also began bringing internet access, telephony services, along with digital TV signals, over coaxial cable systems to their end-users.
A technology that began to emerge in the early 1980s was fiber optics. Fiber-optic communication benefited from low signal loss and very-high capacity, which translate
HUNTSVILLE, Ala. -(July 14, 2021)— Adtran®, Inc., (NASDAQ: ADTN), the leading provider of next-generation multigigabit fiber and fiber extension broadband access solutions, today announced Armstrong is leveraging the Adtran Total Access 5000 (TA5000) 10G fiber access platform with XGS-PON technology to increase competitiveness, market share and the capabilities of its broadband service. Adtran’s solution introduces XGS-PON technology that provides Armstrong with the best long-term fiber broadband investment to support current and future bandwidth demands across its six-state service region.
Armstrong is the 11th largest Multiple System Operator (MSO) in the U.S. and provides cable television, high-speed ZOOM internet with enhanced Wi-Fi and telephone services to residential and commercial customers in Kentucky, Maryland, New York, Ohio, Pennsylvania and West Virginia. The MSO continuously invests in its network to ensure it is prepared to support subscriber demands. For example, it never could have anticipated the COVID-19 pandemic or the resulting escalation in at-home internet usage. Since Armstrong had already invested in fiber-to-the-premises (FTTP) with GPON and engineered its network to be agile and scalable, it only took a few small overnight adjustments to mitigate potential congestion caused by an exponential spike in internet traffic.
Looking beyond 2020, Armstrong knew that new broadband demands would continue to surface, so it looked for a solution that offered the flexibility to easily grow capacity further. More specifically, Armstrong wanted the ability to overlay XGS-PON on the same fiber network as GPON while supporting both CPE types to best serve current subscribers and
