The optical fiber and optical cable industry is more and more concerned by the market, which also makes the market competition more fierce and the price cut. Before 5G deployment is mature, optical fiber enterprises need to go through a difficult period of transition from 4G to 5G.
Based on the business requirements of 5G carrier network and combined with the current situation of optical fiber and cable network, the white paper summarizes the specific requirements of 5G network for optical fiber and cable, and puts forward the optical fiber and cable solutions suitable for the current 5G carrier network construction of all layers, aiming at the subsequent deployment of 5G carrier network optical fiber and cable in China, the promotion of international and domestic standards, and new optical fiber Optical cable R&D and healthy and orderly development of the industry provide reference.
China's optical communication technology has made a breakthrough again. For the first time, the 1.06pbit/s super large capacity single-mode multi-core optical fiber transmission system experiment has been realized. The transmission capacity is 10 times of the maximum capacity of the current commercial single-mode optical fiber transmission system, which can transmit about 130 pieces of 1TB hard disk data within one second. The experiment adopts the most advanced research results in the field of optical transmission system technology, optical devices and optical chip technology, optical fiber and cable technology in China. The core optical chips and optical fiber used are independently developed and have full independent intellectual property rights. It marks that China has stepped to a new step in the field of "super capacity, super long distance, super high speed" optical communication system research.
From the current global 5G base station construction quantity and user demand, China is undoubtedly a big market for 5G demand. At this stage, 5G commercial has been announced in China, but it has not been constructed on a large scale. After the accumulation in the past few years, the current supply of optical fiber and cable exceeds the demand, and the price of optical fiber also fluctuates greatly. At present, optical fiber and cable enterprises are accumulating and breeding, actively exploring and thinking about the future development direction. We believe that after the dormancy period, with the 5G commercial process about to enter the acceleration period, the demand for optical fiber and cable has become the focus again.
