  • Material problems cause degradation of optical cable performance

    Everyone in the optical fiber communication industry knows that the quality of optical cable is very important, not only will it affect the service life of the optical cable, but if it is a power special optical cable, there may also be safety problems due to poor material quality. With the recent decades, Development of China's optical fiber

  • Classification of communication optical cables

    The classification of communication optical cables is divided into: 1) oil-filled optical cables; 2) inflatable optical cables. According to the installation method, it is divided into: 1) overhead optical cable; 2) buried optical cable; 3) pipeline optical cable; 4) underwater optical cable; 5) office optical cable is divided into: 1) layer twisted type; 2) skeleton type; 3) Belt type; 4) Beam tube type.

  • 5 aspects to identify the quality of optical cable

    With different usage scenarios, the types of optical cable are also divided into many types, but from optical fiber to finished optical cable, we generally distinguish the quality of the optical cable from several aspects, as follows: 1: General indoor recording optical cable using poly vinyl chloride Or flame retardant poly vinyl, the appearance should be smooth, bright, flexible, easy to peel. The quality of the outer sheath of the optical cable is not good.

  • Definition and brief history of communication optical cables

    Communication optical cable: Translated into Chinese is a communication optical fiber cable. Formal definition: a certain number of optical fibers form a cable core in a certain way, and the outer layer is covered with a sheath, and some are also covered with an outer sheath, which is a communication line used to implement optical signal transmission. Brief history: The theory of optical fiber was put forward by British Chinese Dr. Gao Yan in 1966. It can be seen that the Chinese are also very intelligent and innovative

  • Communication fiber cable failure cause

    First, the failure of the optical cable line joint is prone to failure at the line joint. This is because the optical fiber at the joint has no protection or weakened the original optical cable structure. Therefore, the daily operation and protection work can only be performed. Depends on the joint box, which leads to a greatly increased probability of failure. 2. Poor insulation of communication optical cable lines

  • How to correctly judge the aging degree of power cable products?

    When multiple customers call for consultation, they always ask, how to judge the degree of aging of power cable products, because during use, it is a normal phenomenon for the product to appear aging! The aging state of the cable insulation is a major basis for determining the service life of the cable. Internationally, there are different standards for the service life of cables.

  • How to repair the broken fiber?

    The fiber is broken. We do n’t call repair. We call fusion splicing. Like welding iron pipes, glass fibers are fused with special machines! This is a fiber splicer, a magic machine. We must first strip the optical cable, we can find that the optical cable is actually a fiber optic bundle, which is composed of many small optical fibers. We use the size of the fiber bundle to mark the size of the cable.

  • Fiber obstacle point error

    1. Intrinsic error of the meter: The inherent error of the meter includes scale error and resolution error. The number of sampling points of the OTDR directly affects the resolution of the distance. For example, the measurement accuracy of the OTDRMW9076B distance is: ± 1m ± 3 × measurement distance × 10E-5 ± marking resolution. For a certain length of fiber, the first two items are constant, and only the resolution is variable.

  • Fiber barrier

    1. Part of the optical fiber blocking obstacles precisely adjust the refractive index, pulse width and wavelength of the OTDR instrument to make it the same as the parameters of the fiber under test, and reduce testing errors as much as possible. Check the measured distance information with the maintenance data to see if the obstacle is at the joint. If the obstacle point has obvious Fresnel reflection peaks observed through the OTDR curve, it is close to the data check and a certain joint.

  • Judgment of obstacles

    According to the nature of the obstacle, it can be divided into two types: one is a fiber break obstacle, and the other is an attenuation increase obstacle at a certain point of the fiber link. According to the actual situation of obstacles, they can be divided into visible obstacles and hidden obstacles. Visibility disorder: It is easier to find, most of which are caused by external forces. OTDR instruments can be used to determine the distance between obstacles and stations (stations) and the nature of the obstacles.

  • The difference between optical cables and cables for broadband networks

    The differences are as follows: 1. Cables are wires, which are used to transmit electricity and information. 2. There are differences in materials. The cable is made of metal (mostly copper, aluminum) as the conductor, and the optical cable is made of glass fiber as the conductor. 3. There is a difference in the transmission signal. The cable transmits electrical signals. Optical cables transmit optical signals. 4, there are differences in the scope of application. Electricity

  • Optical cable standards

    One: The recycling of waste optical cables cannot reach a unified standard. Due to the continuous increase in communication projects, most of the optical cable inventory is relatively dispersed. According to the processing method of communication optical cables, it also combines the inventory of optical cables sold by customers and regional reasons. It is more difficult to realize door-to-door recycling of fiber optic cables. Only by providing a better fiber cable recycling solution can we solve the current situation.

  • Where is the recovery cable?

    Where to find Shijiazhuang recycling fiber optic cable companies, these are actually very easy to find. A search on Baidu showed that all relevant recycling fiber optic cable companies have come out. It is not difficult to find a company that recycles fiber optic cables. The hard part is how to distinguish the authenticity of the information and the quality of the company. We recycle the remaining optical cables, stock optical cables, used optical cables for 4 ~ 288 cores for a long time, and also sell them at low prices for a long time.
