Fiber optic cable
光ファイバーケーブルは、主に通信回線での信号伝送を実現するために使用されます. 使用目的に応じて、電力用光ファイバーケーブルに分けることができます, 通信光ファイバーケーブル, 屋外光ファイバーケーブル, マイニングケーブルなど. では、電力用光ファイバーケーブルと通信用光ファイバーケーブルの違いは何でしょうか。?
In terms of composition, the main component of power fiber optic cable is the conductor, while the communication fiber optic cable is dominated by glass fiber inside. Power optical cable is a cable made of several wires stranded together. Communication fiber optic cable is a fiber optic core in a specific way, and then covered with a sheath to protect.
In terms of application, power fiber optic is used for power transmission and information communication in power systems. Power fiber optic cable is generally concerned with power loss, voltage value, high and low temperature resistance, insulation and other aspects.
Communication fiber optic cable is mainly used in energy signal transmission as well as data transmission. Communication cable contains low-frequency, medium-frequency and high-frequency cables, which are generally concerned with their standing wave, distortion, anti-interference and other properties.
Power fiber optic cable is applied to the power system taking into account the power transmission and information communication of various types of composite cables and special fiber optic cables. It uses the unique resources of the electric power system, and the network structure is closely integrated with the construction. It has the advantages of fast, efficient, economical, safe and reliable, 等.
Power fiber optic is mainly placed on of power poles of different voltage levels. Its electrical characteristics, mechanical characteristics, resistance to external harsh environment are stronger than ordinary optical fiber cable. Overhead fiber optic cable OPGW and ADSS are the common power optical cable.
When laying the power optical cable, there is no need to set up the poles or towers. So that it can save the construction budget with its fast construction speed and short construction period. And it also does not affect the normal operation of the transmission line. And this overhead fiber optic cable is easy to repair, and later maintenance does not need to affect the transmission line. It also has good impact resistance and is not easy to fail.
Communication fiber optic cable is a certain number of optical fibers in accordance with a certain way to form the core covered by the outer sheath, to achieve the transmission of optical signals of communication lines.
Communication fiber optic has greater transmission capacity than power cable. It has a long relay section distance, small size, light weight, and is not subject to electromagnetic interference. Communication fiber optic cable has been developed into the backbone of transmission lines for long-distance trunk lines, transoceanic submarine communications, and local area networks, private networks, 等. since 1976. 現在のところ, communication fiber optic cable is providing high-capacity high-speed transmission lines for fiber-to-the-home and broadband integrated service digital networks.
