Our Story

For more than 20 years FiberLight has been pushing the boundaries of business-class fiber networks. From meeting the needs of under-served municipalities to connecting metropolitan enterprises, FiberLight has delivered top-tier fiber networks for businesses across numerous industries. Our world-class connectivity solves our customers’ most complex needs and positions them for business success today and in the future through creativity, industry know-how and proven excellence.

Fiberlight story

Over the years, FiberLight has experienced the rapid growth of connected businesses and users alike. Digitalization across all sectors has driven up demand for increased bandwidth, agility and reliability of their networks. Through our more than 19,000 route miles in some of the most densely populated metroplexes, fast-growth tech hubs, and under-served rural areas, FiberLight has put the power of its owned networks into the hands of our customers so that they can exceed their business goals with confidence through fast response times, increased uptime and minimal network interruptions. Our dark and lit fiber networks provide our customers with the reliability, resilience and flexibility they need to serve their customers and plan for future growth.

Our customers aren’t restricted by today’s ever-increasing bandwidth requirements. In industries and organizations where technology growth and user demand are skyrocketing—manufacturing, farming, education, state and local governments—FiberLight empowers customers to handle increased user engagement, data center connectivity, expanded network capacity, and next-generation learning. Our network continues to be at the forefront of our customers’ innovation.

Today, FiberLight is meeting and exceeding the high bandwidth demands of the digital economy throughout Texas, Florida, Georgia, Maryland, Virginia and Washington D.C. Our network continues to provide world-class networking solutions and exceptional experiences for our customers, partners and community.

FiberLight is well-positioned to deliver new routes, adding to our stretches from densely populated cities like Miami–which provides connectivity between Central and South America and the United States–to the country’s rural heartland. Our focus is on the continued building and operation of future-proof networks for an interconnected world.


1993 – 2005

FiberLight predecessors ACSI, ACSI NT, and Xspedius Fiber Group (XFG) build a reputation for building reliable high-bandwidth networks for telecom carriers, ISPs, and utility operators within state and local rights-of-way across the United States.


FiberLight is born when Thermo Telecom Partners purchases, restructures, and rebrands XFG. FiberLight continues to build custom turn-key fiber networks for network operators, government agencies, and high-tech companies within its footprint in the southeast United States.

2007 – 2009

FiberLight adds managed optical transport offerings in 8 of its core metros, acquires a 20-mile network in Waco, TX, adds long-haul offerings in Texas, and connects Washington, DC to Culpeper, VA via new 132-mile build.

2010 – 2012

The launch of a new Dedicated Internet Access product and continued expansion in Maryland, Virginia, and Florida culminate in the ground-breaking of our 8,000 mile network expansion, designed to connect rural cell towers in West and Central Texas.

2013 – Present

FiberLight announces a 100G DASH Network, additional construction in Texas to the Mexico border and through the Valley, an overbuild in Ashburn, and two new products (Long Haul & Cloud Connect).

We are always working with new clients who will require additional network connections into the Carrier-1 facility. FiberLight is at the top of our list to either resell their services or recommend for direct services.
