Rewiring your house for fiber optic is not always necessary. It depends on the existing infrastructure and wiring in your home. In some cases, fiber optic cables can be installed alongside existing wiring systems, utilizing the same conduits or pathways. This is due to several potential risks and complications that can arise from such an arrangement. Electrical Interference: Electrical cables can produce electromagnetic. Utilities build fiber optic networks in similar ways that others build them, aerial and underground, but they also mix aerial cables in their power distribution cables, sharing towers and poles. In order to do this, they use some very different types of cables. Besides the use of special cables on. Your traditional copper wire-based service is being replaced with fiber optic technology. Why did I get a letter? You received a letter from AT&T to let you know about the upcoming changes to our network, how it will affect you, and what to expect. This fundamental difference is what enables its incredible speed, lower latency, and superior reliability.
