Atlantic Broadband has inked a deal to acquire all of FiberLight’s South Florida fiber network, more than doubling the cable operator’s fiber footprint in the region.

Terms of the deal were not disclosed.

The purchase includes about 350 route miles of fiber, expanding Atlantic Broadband’s network to cover 7,000 route miles and 25,000 on-net buildings reaching from Maine to South Florida.

Atlantic Broadband, the ninth largest U.S. cable operator, said the acquisition enables it to significantly speed up its expansion efforts for fiber-delivered enterprise and carrier services.

As part of the deal Atlantic Broadband has purchased dark fiber from FiberLight that will allow the company to start offering advanced enterprise communication solutions across its entire network footprint right away.  

“With interconnections to every major data center and nearly 200 on-net buildings throughout South Florida, acquiring FiberLight’s high quality and high capacity fiber network will cement our position as a leading provider of business communications services in South Florida,” David Isenberg, Atlantic Broadband president and CRO, said in a statement. “We look forward to playing an even greater role in supporting and enabling the innovation and economic growth that has characterized this region.”

The deal is expected to close within six months, the company said.

“We are pleased to forge a new partnership with Atlantic Broadband to enable the expansion of their business in the greater Miami market, while at the same time, allowing FiberLight the opportunity to re-invest in our Texas and Northern Virginia markets which are experiencing significant growth,” Don MacNeil, FiberLight CEO, noted.

FiberLight owns more than 1.3 million miles of fiber networks in more than 44 key growth areas in U.S. cities and towns within Florida, Georgia, Maryland, Texas, Virginia and Washington D.C.

Earlier this month, Atlantic Broadband closed on its $1.4 billion purchase of MetroCast Cable systems. Previously owned by Harron Communications, MetroCast systems pass about 236,000 homes and businesses in Main, Maryland, New Hampshire, Pennsylvania, and Virginia.
