Atlantic Broadband said it has completed the purchase of FiberLight LLC’s South Florida fiber network, a deal that will significantly increase the cable operator’s high-speed fiber footprint in the state.

Atlantic Broadband first announced the FiberLight deal in January. The deal, adds 350 fiber route miles to the cable company’s existing South Florida network, roughly doubling its footprint in that part of the state while increasing its ability to serve data center customers in that are by about 30%.

“As the region grows and more businesses enter, we are excited that we can now offer this expanded fiber network,” Atlantic Broadband CEO Rich Shea said in a statement. “Through this strategic partnership, we are giving businesses the ability to innovate, grow and contribute to the region’s economic growth - a commitment that we’ve made to South Florida and all the geographies we operate in.”

The latest deal comes on the heels of a series of transactions over the past few years, including the purchase of MetroCast Cable Systems in January, which enabled Atlantic Broadband to offer a diverse footprint extending up the East Coast from Florida to Maine.
