Optical communication industry: today ushered in a new boom period

Recently, the optical communication industry news, ushered in a new boom period.China has realized the experiment of optical transmission system of 1.03Pbit/s ultra-high capacity WDM and air division multiplexing. The transmission capacity is 10 times of the large capacity of the current commercial single-mode optical transmission system, and the data stored by about three 1TB hard disks can be transmitted within one second.This indicates that China has made great progress in the research field of "ultra-large capacity, ultra-long distance and ultra-high rate" optical communication system.Today, mobile issued a large purchase order, centralized procurement of ordinary optical cable products, the amount of more than 10.1 billion yuan.

At present, with the increasing prosperity of mobile Internet applications and the rapid popularization of high-traffic applications, the demand for data traffic will grow exponentially, and the existing communication network bandwidth of operators is facing huge pressure.In the next 3 to 5 years, backbone communication networks and MAN will continue to be built and expanded, and the expansion of communication industry infrastructure will continue.It is expected that following China Mobile's purchase of 10 billion yuan, China Unicom, China Telecom and other operators are also expected to carry out large purchases.

At present, China has accounted for more than 50% of the world's production capacity in the field of fiber optics and fiber prefabricated rods.New technologies such as ultra-high capacity wavelength division multiplexing and space division multiplexing optical transmission systems are expected to further improve optical fiber data transmission capacity and save investment in optical communication equipment.

Despite the progress made in the field of optical communication, China's optical communication industry is still facing the pain of "lack of core".In the upstream industry, most of the key components are imported.In the field of optical devices, high-end products are heavily dependent on foreign countries.For example, Optical Xun Technology, Hisense Group and other domestic enterprises only produce active chips with energy less than 10G at present, and almost all 25G and 100G high-speed optoelectronic devices rely on imports. In the field of 400G/1T with higher speed, foreign enterprises have exhibited corresponding samples, and China has not yet entered the theoretical design stage.Relevant manufacturers need to speed up technological progress, achieve common progress of the whole industry chain, and better share the market opportunities brought by the industry boom
