Fiber Optic Cable Brands

High-performance cabling systems today widely use optical fiber. For SCS and local area networks and premises with increased danger - this is the most reliable technological solution. The structure of an optical cable is as follows: a fiberglass core is placed in a protective sheath.

In accordance with the characteristics of the structure, the purpose of the cables is determined. The nomenclature of the fiber optic cable allows you to clarify the purpose, thanks to the coding. The structure of the symbol codes the manufacturer's brand, the type of protective armor cover, the type of core and the number of its elements, the type of optical fiber and its amount in the cable, the maximum tensile force. The brands of optical cables of Russian manufacturers OKA, EKB, etc. are the abbreviation of the manufacturer's plant. The type of core, sometimes referred to as an optical fiber, determines the basic classification into single-mode and multi-mode cables depending on the transmitted light rays. This classification determines the functionality (from the English mode-mode of operation).

 

Multimode and singlemode optical cables disadvantages and pros

Multimode optical cable is most widely used in LANs. An example of its use is Ethernet, which is the basic topology for a LAN. Its essence is as follows: computers of an office or enterprise are connected to a common cable. The use of an optical communication cable in this case is the optimal solution to this issue, due to the high speed characteristics of signal transmission. The disadvantage of multimode cables is the dispersion of several light fluxes.
A single-mode optical cable is devoid of this drawback, since only one beam of light propagates in it.

With higher performance, they have found their way into telecommunications systems, but are more expensive. The advantages that make cable networks cheaper and make them safe to use include the lack of grounding of optical cables. Due to this characteristic, a self-supporting optical cable (located separately) is used for external laying between buildings, for suspension on the poles of communication lines, power transmission lines, and railway overhead lines. Its low weight makes cable breakage unlikely and improves safety.
