The development of indoor fiber optic cable

Indoor fiber optic cable is a fiber optic cable laid in the building, mainly used for communication equipment, computers, switches and end-user equipment in the building, used to transmit information. Indoor fiber optic cable mostly uses aramid as a reinforcing member, with small outer diameter, good flexibility, easy to bend, fast transmission speed, clear and stable signal, good anti-interference performance, high transmission flow, suitable for indoor or space for smaller occasions deployment. Indoor fiber optic cable is generally not long distance, you can use multimode fiber, the same multimode bandwidth can be used gigabit, 10 Gigabit fiber optic cable respectively. Communication units will consider the bending-resistant G.657 type of optical fiber, representative of the butterfly cable and so on. Indoor fiber optic cable has a variety of shapes, usually containing 1-36 cores, mainly single-core, dual-core, multi-core three.

　　Indoor fiber optic cable user groups are mainly optical device manufacturers, integrated cabling manufacturers, network integration companies, real estate developers, communication operators, broadcasting companies, military use, etc. At present, the main market directions are patch cord category, cabling category, carrier category and other industry categories. Jumper class is mainly a variety of patch cords, connection plugs, handover boxes and end-user use; cabling class is mainly used for wiring in houses or equipment, which can be vertical wiring, horizontal wiring, house wiring and end-user wiring, etc. Currently, the largest amount of butterfly introduction fiber optic cable is used in this market, and it is expected that more types of fiber optic cable forms will appear in the future in the application of wiring; because of the massive use of field connectors, the So that a large number of indoor fiber optic cable use in the end will be directly installed in the field connector components, so operators rarely directly tender for the purchase of indoor fiber optic cable; other industry categories are mainly military, aerospace, automotive, high-speed rail, coal, medical and non-communications applications.

　　Although the current user side of the communication cable or super five network cable is dominant, but with the rapid expansion of online data, access networks and user premises a large number of increases, super five network cable will be difficult to meet this development demand, the market for indoor fiber optic cable will steadily expand year by year, the situation is very optimistic, which is the development trend of the market. With the increase of aramid demand, data center construction and other factors, indoor optical cable market demand is also rising rapidly. 

　　Aramid is used as a protective material for indoor optical cable, and the market demand is also expanding gradually in recent years, according to the "2017-2021 China para-aramid industry development prospect analysis and development strategy research report", the market demand for para-aramid in China was about 10,122 tons in 2016, and it is expected that by 2021, the market demand for para-aramid in China will reach 18,040 tons. The growth in demand for aramids also reflects the growth in demand for indoor fiber optic cables as well. 

　　In addition, the rapid development of new data centers, cloud data centers, supercomputing centers, indoor fiber optic cable products will also usher in a huge development space, data center rooms in the optical cable channel mainly using 10 Gigabit network, the construction of data center rooms will certainly become a new engine of indoor fiber optic cable applications. According to statistics, at the end of 2017 in the global nearly 400 mega data center, China accounted for about 8% of the construction growth rate of about 100. 2018 China's data center market will reach 140 billion yuan, operators occupy 65% market share. Based on the 5G edge computing base, edge data center construction will be developed in the future and will assume a considerable portion of data storage capacity, which will have a certain impact on large data center construction and market operation. At this stage, data centers are still dominated by electrical connections, but optical connections will definitely become a major trend, which will definitely bring new economic growth points to indoor optical cables.  

　　Market demand is the leader of industrial development, and also the leader of enterprise development. With the rapid development of information networks, indoor optical cable development of external conditions have been available, the government's policy of expanding domestic demand, optical cable transmission content increased, data center construction, etc., these conditions are for indoor optical cable vigorously develop to provide a guarantee. In the face of such a form, it is necessary for each enterprise to analyze and understand different requirements for different customer groups, adopt different market strategies and product strategies, accelerate innovative research on indoor optical cable products, step up technical updates and upgrades, promote the development of indoor optical cable industry, enhance the level of indoor optical cable, and adapt to the current development trend.
