Transmission distance of cable TV optical cables
Using single-mode fiber cable means it can carry a signal up to 100 kilometers (over 60 miles) without serious loss. Nevertheless, that's plenty for indoor or short outdoor use. Transmission distance decreases as the bandwidth increases. For example, a fiber optic cable with a distance of 1km supports a bandwidth of 500MHz, while a fiber optic cable with a distance of 2km can only support a bandwidth of 250MHz. There are three main reasons for this: First, high-bandwidth. Fiber optic cables are the backbone of modern communications, enabling high-speed data transfer over vast distances. Attenuation is the progressive loss of signal strength that occurs as light travels through the fiber.
