UV Optical fiber bunch mainly use in air-blowing cable for light in weight
Mesh optical fiber ribbon is a new type of optical fiber ribbon. Compared with traditional optical cables, mesh optical fiber ribbon can effectively solve the prominent problem that the traditional underground access network scheme can not meet the needs of the current rapid development of broadband access network under the condition of maintaining the same outer diameter. The core technology of mesh optical fiber ribbon lies in the optical fiber ribbon. Its soft and curlable characteristics enable it to accommodate a higher number of cores in a certain volume, so as to improve the overall number of cores of optical cable. The production of mesh fiber ribbon requires special equipment.
Compared with ordinary single core optical cable, ribbon optical cable has obvious advantages in construction, connection, termination and many other links. Therefore, it is more and more widely used. It is embodied in the following aspects.
1. Hundreds of core optical cables, with small diameter, light weight, good bending and strong lateral pressure resistance, are convenient for laying and construction.
2. Generally, multi-core is one area, which can be connected at one time, with high speed, less time-consuming and high construction efficiency.
3. It is easy to disk fibers, and the sequence is not easy to make mistakes.
4. The maintenance and obstacle repair of ribbon optical cable are also convenient.
Of course, since multiple cores are a group, attention should be paid to all links of construction to ensure that each core is normal as far as possible. If one or several cores are found to be faulty during construction and maintenance, and other cores have been used, the faulty core may be abandoned, and the waste of optical fiber may occur
