In ancient times, when the frontier soldiers found the enemy’s trail, they ignited the beacon to transfer the sign of threat to their hometown. This is the ancient way ofoptical communication.Nowadays, engineers use quartz-madeopticalfibers to transmit optical signals, which enables thefast transfermation of huge amounts of information worldwide. Optical fiberlookslike very simple, it isas thin as hair, being composed of silica and some other material that originated from soil. On the other hand, optical fiber can be complex, it can achieve many different transmission performances through different "formulations" and different structures though it is just made of simple materials. 

With the rapid development ofglobal informatization, optical fiber has been upgraded from the cornerstone of optical fiber communication to the fundamental medium for information technology. Driven by Internet +, Internet of Things, 5G and other technologies, countries around the world have proposed the construction of all-optical networks, makinginformation collection, transmission, and processing could be processed in the form of light, which greatly increases the information transmission capacity and the transmission rate.Applications covering a variety of scenarios, including environmental application in space, ground, and oceans, are requiring fiber optical cables to evolve into microstructure.The scope of microstructure fiber technology is a multidisciplinary subject, and its basic theoretical issues are still under exploration. There is no precedent design that can be followed, and it is also very hard for the current technique to be applied in this new area.

Bystuding the scientific principlesand equipment relating to optical fiberssystematically, processing,FiberHomehas made pioneering technological innovations in many areas such as structural design, manufacturing process and product research and development. FiberHome successfully developed the key technology of high-stability micro-structured optical fiber cable among the world's leading ranksin this field. With this achievement, FiberHome won the first prize of China Institute of Communication in 2019 for technological invention.

Aiming at solving the problem of oriented design of structure and function, FiberHomehas established a dynamic formation model of microstructured optical fibers, and developed a kinetic mechanism and precise-control method in the fabrication of microstructured fiber. FiberHomehas also proposed a lot of innovative technologies such as the control tehchnology on "three-stage seamlessly connected narrow temperature field", mechanized lattice arrangement, and etc. A set of systemwith independent intellectual property rights on precise manufacturing process of photonic crystal fiberhas beenestablished. FiberHomehas also foundeda microstructure fiber development platform with functional convergence characteristics for structural performance stability parameter design. Microstructure fibers withmicroholessize from millimeters to micrometers can be accurately and stably prepared. FiberHome has also solved the problem of the melting of "multi-quartz capillary integrated composite"at high temperature,which guarantees the uniformity of the internal structure of the microstructured fiber as well as its functional realibility.

Pic.6 OAM micro-structured fiber

FiberHome is the first company whichhas produced a photonic crystal fiber with a zero dispersion point at 1060nm in China. Meanwhile, FiberHomehas also creatively developed high-performance OAM micro-structured optical fibers and low-loss multi-mode optical fibers which can support 96 OAM modal transmissions.Withthe few-mode multi-core fiber, FiberHomeaccomplished the experiment of 1.06Pbit / s ultra-large capacity WDM system and space division multiplexing optical transmission system.It realized the leap of transmission capacity from Tbit / s to Pbit / s,which means that it only took 1 secondto transmit 130TB (1TB = 1000GB) data. The data capacity is equivalent to more than 40 million songs, or 30 billion people who have two-way conversation at the same time.FiberHome will continue innovating so asto realize the innovative development and industrialization of new optical fiberstogether with domestic counterparts, and will make further contribution to the development ofinformation technology in China.
