HIGH POINT, N.C.--(BUSINESS WIRE)--Lumos, a leading 100% Fiber Optic Internet and network infrastructure leader, today announced its expansion in Charleston County, South Carolina. As part of this initiative, Lumos will build more than 500 miles of fiber infrastructure, bringing high-speed internet to over 50,000 homes, small businesses, and multifamily communities in Mount Pleasant and the surrounding area.

Lumos, now part of T-Mobile Fiber, is expanding its fiber network to strategically grow and support Lumos’s mission to strengthen South Carolina’s digital infrastructure, introduce greater broadband competition, and empower more communities with the connectivity they need to thrive. The network will provide service to consumers and businesses via T-Mobile Fiber, in addition to large businesses and bulk MDU complexes which will be under the Lumos brand.

Lumos’s fiber network, used to power T-Mobile Fiber’s residential internet service, brings advanced fiber optic technology to areas built to support remote work, online learning, telehealth, and the digital tools families and businesses rely on every day.

Brian Stading, CEO of Lumos, shared that the expansion is a testament to the company’s growth and is proud of the support Lumos will bring to coastal communities in South Carolina.

“At Lumos, we believe that reliable, high-speed fiber internet is the backbone of thriving communities.
