Bending a fiber cable over its MBR is one of the biggest factors in fiber damage in projects to install fiber cables. This practice can break the fibers inside or increase fiber attenuation (fiber power loss) than the manufacturer’s specifications. Although the internal fibers are already broken, you can not see any physical damage to the outer skin at all. As a result, you must replace the entire section or even the entire length of the cable. As a good practice, all fibers must be thoroughly tested after cable installation. More info from jiafu fiber optic cable manufacturer

The science of fiber optics has its advantages and disadvantages. Though there are more advantages than disadvantages, they still are there. One of the largest disadvantages is the overall price of manufacturing and installation of the fiber optic system. Not only is a large amount of glass wire needed for one of these systems, but expensive transmitters and receivers are needed to move the data it carries. Setting up the wires and splicing them also comes at a large expense and also with a great degree of difficulty.

An optical fiber (or optical fibre) is a flexible, transparent fiber made of glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection. This causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those that only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,050 meters (3,440 ft).
Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together, either mechanically or by fusing them with heat. Special optical fiber connectors for removable connections are also available.
