Fiber optic cable advantages



The fiber optic cable has the advantages of light weight, small size, long transmission distance, large capacity, small signal attenuation, immunity to electromagnetic interference, which has been widely adopted by a variety of networks. With the advent of the 21st century, fiber optic cable has become the subject of network data transmission, telecommunications, cable radio and television and other private network. At the choice of twisted-pair cable, and coaxial cable, we can roughly determine the performance of the pros and cons by visual inspection and simple test, and the choice of fiber optic cable from professional fiber optic cable manufacturer is not so simple, compared with the twisted- pair cable, coaxial cable, not only the structure is complex, a wide variety of materials, there are many potential factors (materials, production processes, equipment, etc.) in addition to the existing technical parameters. If there are the slightest mistakes, let alone two or three years of service life is not guaranteed, the number of years of technical parameters may not be reached. Therefore, it is very necessary for us to have a deep knowledge and understanding of the structure, materials, and processes of the fiber optic cable in the construction of the network, in order to buy the right types of high-quality fiber optic cable.

Optical Cable

1. Choose fiber optic cable according to the number of cores



The structure of different types of fiber optic cables is divided into center beam tube, stranded, skeleton and ribbon type. The structure of different uses is not the same, the user can make any such request depending on line conditions. Generally less than 12 cores use the center beam tube, the center beam tube process is simple and low costs, which is competitive among pipeline protection network with a good branch trunk overhead installation; Stranded optical cable places a strand or single root steel wire reinforcement on the center, using SZ to continue synthesis cable into a cable, the core fiber is up to 144. Its biggest advantage is waterproof, powerful resistant, strong-side pressure. Can be used for direct bury.

2. Select optic cable according to the purposes



Depending on the application, fiber optic cable can be divided into aerial optical fiber cable, buried cables, pipes cables, submarine cables and metal-free fiber-optic cable. Aerial optical fiber cable requires high strength, small temperature coefficient; Buried fiber optic cable requires anti buried, compression resistant, moisture-proof, anti-humidity characteristics, resistance to chemical attack; duct and submarine cable will have to water pressure resistance, resistance to tension, good waterproof characteristics; no metal fiber optic cable produced by electrical cable manufacturers can be erected with high-voltage lines, insulation is better, although there is no iron body strengthening core, it also has a certain degree of tensile strength. Therefore, in the purchase of the cable, the user should choose according to the use of fiber optic cable, and request the manufacturer to ensure that the stable, reliable use of fiber optic cable.
