Compared with 4G era, the number of 5g base stations will increase several times, and as the physical connection channel between base stations, the demand of optical fiber and optical cable will also surge.
In the construction of optical communication network, on the one hand, due to the continuous growth of optical fiber access demand, the number of optical fibers contained in a single optical fiber cable increases significantly, and the volume of optical cable needs to be expanded accordingly; on the other hand, the existing pipe network resources carrying optical cables are relatively limited, and the volume of single optical cable is limited, which puts forward higher requirements for the design and manufacture of conventional optical fiber and cable products.
With the increasing comprehensive demand of the existing network expansion, pipeline network channel upgrading and data center, high-rise buildings, large stadiums, transportation hubs and other emerging high-speed network construction, the mainstream market is more and more inclined to higher core density and larger number of core optical cable products, and the new optical cable will develop in the direction of super large core number, ultra-high density and super flexibility. Due to its advantages of convenient construction and small outer diameter, large core micro bundle tube optical cable is favored by European customers. At present, most of the micro tube optical cable products widely used in the market are focused on 288 core or below structure, and the core density is relatively low.
At present, only a small number of international optical fiber and cable suppliers have the capacity of mass production of high fiber density and large number of cores, and are in a monopoly position in the market. The high fiber density structure optical cable series products of major domestic manufacturers are basically in the initial stage, and the technology maturity is low. There is still a certain gap between the actual fiber density, mass production scale and key indicators with the international leading level. Therefore, we still need to make unremitting innovation, launch continuous challenges to optical cable products with larger number of cores and higher optical fiber density, and work with customers to maximize the optical fiber potential and help everything interconnected.
