End-to-End Fiber Broadband
Federal and state programs are accelerating fiber deployments, and communities are quickly moving from planning to construction. The winners will be the partners who can permit faster, build safely, and operate reliably—with the people, fleet, and process discipline to deliver on schedule across rugged New England conditions.
Sertex brings three decades of outside plant fiber experience to close the gap between planned and lit networks. We integrate engineering, aerial and underground construction, splicing and testing, customer installation, and ongoing operations—so you get one accountable partner from backbone to drop to activation to maintenance.
We now operate from two strategic New England locations: our long-standing headquarters in Plainfield, Connecticut, and our regional office in Sidney, Maine. Together, these locations strengthen our ability to mobilize crews, equipment, materials, and engineering resources for broadband projects across the Northeast.

Advancing Universal FTTH Across
New England’s Hardest Miles
Sertex is one of the Northeast’s most effective builders of fiber infrastructure, with the regional reach to support broadband deployments from southern New England to rural Maine. From our headquarters in Eastern Connecticut and our Sidney, Maine regional office, we partner with municipalities, public agencies, utilities, and ISPs to design, build, test, and activate fiber networks in places often considered too remote, too complex, or too costly to serve.
All Sertex crews are trained and certified to handle outside plant construction and installation, including aerial and underground construction, backbone, feeder, distribution, fiber splicing, testing, drop connections, and service activation.
What Our Customers Say
“Marlboro residents are excited to see DVFiber hanging strand and fiber on the poles in their neighborhoods. Many have gone out of their way to express that Sertex crews are both professional and friendly, welcoming public curiosity. By leaving a positive impression wherever they work, Sertex is not only advancing the construction of our fiber network but also enhancing DVFiber’s reputation as the ISP of choice in southeast Vermont. Kudos!”
“The reviews of the Sertex employees have been universally positive. If I were running a company, it would be a source of such great pride for me to have the ability to find and train people who seem to actually give a damn about our network working well.”
“Through our partnership with Sertex, we are expanding high-speed fiber infrastructure in downtown Hyannis to promote digital inclusivity and innovation. We trust Sertex crews to deliver the same dependable, high-quality technical and customer support service in Hyannis that they’ve provided to our projects over the past decade.”
“I wanted to drop you all a line to say how excellent the service was, and how efficient, tidy, and precise the installation work was. In addition, the technician was extremely patient when answering questions, walking me through the process step by step. The technician even provided me with information on Wi-Fi boosters should I find I need them for better coverage. All in all, exemplary service from a real professional.”
