About broadband in Sulphur
In September 2021, Vexus Fiber announced a $50 million build for a 100% fiber-to-the-home network across Lake Charles, Sulphur, and Westlake, reaching more than 40,000 homes and businesses with symmetrical multi-gigabit speeds and construction starting in the first quarter of 2022.
