In 2019, China’s 5g will enter the first commercial year. On April 8, 2020, China Mobile, China Telecom and China Unicom jointly held an online conference to jointly release the “5g news white paper”, marking the formal and comprehensive launch of 5g commerce in China. While bringing new opportunities, 5g also brings new challenges to “new infrastructure”. 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 increase rapidly, which has become the key of deployment in the early construction of 5g network. Professor of Harvard University Dr.Susan Crawford pointed out in his book fiber that “the future of advanced wireless services depends entirely on the number of optical fibers.”.

The future of 5g advanced wireless services depends on the number of optical cables

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.

Large core number of micro tube optical cable, promising

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. In 2019, Fiberhome’s 432 core large core micro tube outdoor optical cables are widely used in Europe. In June 2020, Europe’s big T will use Fiberhome’s 864 core high-density and large number of core micro tube optical cable products.

Fiberhome independently developed 864 core micro bundle tube optical cable, the diameter of which is only about 22mm. The fiber assembly density is 1.25 times higher than that of the same type of traditional optical fiber loose tube structure optical cable, and 1.6 times higher than that of optical fiber ribbon structure cable, which can save pipe network resources to the maximum extent; the micro beam tube unit is easy to be stripped, easy to construct, and can effectively improve the construction efficiency; the tensile force of the product is also improved The value can be more than 4000N, which can fully ensure that the optical cable will not be damaged by external tension in the construction process. This kind of optical cable can meet the requirements of 110mm diameter bending and 220mm diameter U-shaped bending, so as to ensure that the optical cable can calmly cope with various twists and turns in the complex pipe network environment, so as to fully guarantee the communication quality. Under the extremely cold environment of – 40 ℃ and high temperature of + 70 ℃, the series of products can ensure good working and operating conditions without fear of extreme climate conditions.

Based on Optical Valley, focusing on the world, and continuously catching up with the world’s advanced level

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.

With the market and core technology as the driving force, Fiberhome has successfully completed the research and development of 864 core micro tube optical cable, and has achieved stable mass production. This achievement is an important milestone in the development of China’s high-density and large core optical cable products, marking that the design and manufacturing level of ultra-high-density and large core number micro tube optical cable has reached the world’s advanced ranks. In the face of the “new infrastructure” demand of 5g new network infrastructure such as data center at home and abroad and the national strategic needs, Fiberhome communications will continue to innovate, launch continuous challenges to fiber optic 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 connected.
