A Connecticut-based company playing a key role in building the backbone on the Maine Online Optical Statewide Enabling Network project has opened an office in Sidney to serve as the center for its construction, engineering and logistics work as part of the state’s broadband expansion.

That expansion is now underway, with much of the work focused on building the infrastructure needed to connect some of the state’s most rural and underserved areas. 

Sertex Broadband Solutions is playing a key role in constructing the backbone of the MOOSE Network project, a 530-mile fiber network designed to improve internet access across 131 communities.

Rather than connecting directly to homes, the project focuses on “middle mile” infrastructure. That means that high-capacity fiber allows local providers to deliver faster and more reliable services to residents and businesses across the state. 

The infrastructure is expected to make a noticeable difference for more than 11,000 Mainers who currently lack adequate broadband access, while also reaching more than 200 community anchor institutions, including schools, hospitals and libraries. 

“This is about whether a student in Washington County can access their virtual classroom, whether a lobsterman in Vinalhaven can upload compliance reports, and whether an elderly resident in Aroostook can attend a cybersecurity class to avoid the next scam,” said Jenna Ingram, senior manager of communications at Maine Connectivity Authority. “It is made up of high-capacity fiber that carries large amounts of data at high speeds over long distances.”

By expanding broadband access across Maine, the project aims to strengthen the economy, improve educational opportunities and support better health care access through services like telehealth.

“Expanding broadband access in Maine contributes to a thriving economy that benefits individuals and industries, said Ingram. “Artificial intelligence and automation are reshaping industries at a global scale. Without the digital skills to match, our workforce risks being left behind.”

Sertex was chosen in 2025 to design and build a majority of the network. The work involves installing fiber both above and below ground as well as testing the network to ensure long-term reliability. 

However, building the network across Maine presents unique challenges, Ingram said. With dense forests, rocky terrain, and island communities that require undersea cables, the construction requires a combination of strategies. 

Despite those challenges, the long-term goal is to create a more connected and competitive state. By establishing a strong broadband backbone, MOOSE Net will allow local providers to expand services more efficiently and at lower costs, ultimately helping to bridge the digital divide, said Ingram.

Sertex has already created an apprentice program that has been approved by the Maine Department of Labor to build and train a workforce. 

“The MOOSE Net route is mapped out, and communities will continue seeing field crews at work, with improved connectivity benefits available by 2027,” Ingram said.
