Analysis of the disadvantages of overhead optical cables for communication
Additionally, some communities may object to the visual impact of overhead cables, leading to regulatory hurdles and aesthetics concerns. Another challenge with aerial fiber deployment is that it is fragile. It can strain and slump, especially under extreme weather conditions . Fiber optic cables suspended overhead are exposed to atmospheric conditions and must be protected from extreme weather, including wind, rain, and lightning, as well as potential damage from animals and birds. This means the cables must be insulated for extra protection, which demands more effort. This article will compare overhead vs underground deployment for FTTH networks, discussing their key differences, advantages, and disadvantages in various outdoor environments. There are many causes that lead to the poor installation of FTTH networks. A damaged cable section can often be repaired or replaced in a matter of hours rather than days. Aerial cables are fragile and will strain, sag, and eventually break when exposed to.

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.
