Fiber optic cables are used in the construction of data transmission networks. At the same time, fiber-optic lines can be made of various materials and using all kinds of technologies that determine the quality of the cable and its throughput.
Number of mods
The choice of cable should be made in accordance with the purposes for which the line is installed. If you choose a wire for laying a regular backbone, you can purchase a product with a wire or cable support. Such a cable has single-mode fibers, the number of which can start from 16 and end with 48. Also, single-mode wires have a higher coverage area and data transmission distance, which means that when laying the backbone, the total cost of the installation will be much lower than that of multimode. Single-mode cable is usually used for laying telephone networks and cable television.
Multimode cables are capable of transmitting large amounts of data in several waves, which is its main advantage. Such products are used in the construction of cable Internet networks. Multimode fiber will help provide higher data rates than singlemode fiber. Nevertheless, multimode wires lag significantly in quality and their use is not justified if you want to lay a network whose length exceeds 400 m. Such products are suitable for laying networks over short distances.
Cable characteristics
Having dealt with the type of cable, it is necessary to determine the required characteristics for the cable network. When choosing a product, it is important to pay attention to characteristics such as shock loading, which is an indicator of the protection of the wire and its core from shock. Another important parameter is the allowable bend, which indicates the maximum possible radius of curvature of the wire. It is important that this figure is higher if you plan to install through a sewer network, pipeline or cable duct.
Neglect of this parameter can lead to a violation of the integrity of the light guides of the wire and cause the product to fail. Another important characteristic of the wire is twist (the degree of protection of the fiber by the sheath of the cable) and protection against moisture penetration into the cable, which will become important if you use the wire outdoors.
The choice of cable should also be made depending on the place of use. For example, optical fiber for a room must have fire protection and not contain a gel, so that when heated it does not change its structure and subsequently does not spread.
For outdoor use, armor and a dense layer of fiberglass will be a plus, which will protect the cable from external influences. It is also important that such a cable has a reduced coefficient of friction, as well as internal and external polyethylene protection. These characteristics are achieved by applying additional materials to the wire.
