While fiber optic cables do not directly carry electricity, they can be used to convert energy from light into electrical energy. Long. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances. Fiber optic cables are praised for their high performance and scalability, while copper cables remain a cost-effective choice, especially for budget-conscious projects and older systems. This limitation requires additional.
