Industry at the top of the fiber pyramid: fiber pre-fabricated Rods

The pre-made rod is also known as a light rod and has been regarded as an industry at the top of the fiber pyramid. The fiber pre-made rod and drawing process directly determine the production cost, quality and profit of the fiber optic cable enterprises. Executives of well-known fiber optic cable companies once said, "If the problem cannot be solved, enterprises will always be working for others ." The importance of the fiber optic pre-stick is evident.

At present, the fiber optic pre-fabricated rods in China have the R & D and manufacturing capabilities through introduction, digestion, and absorption. With the continuous investment in R & D by many well-known fiber optic cable enterprises in China, the production capacity of fiber optic pre-rods of major optical fiber cable Enterprises in China has been released and can be self-supplied. With the fiber optic pre-production rod, that is, having the largest profit in the industrial chain and the production capability of the fiber optic cable integration, the cost and profit advantages of the fiber optic cable can be maximized externally, the product quality and performance can be fully controlled to maximize product competitiveness.

It is understood that the current mainstream Optical Fiber manufacturers in China already have the rod manufacturing capability, but compared with the foreign leading level, there are still many problems in domestic manufacturers. In this regard, some experts listed three major problems in the current domestic fiber pre-fabricated rod industry:

First, the technology and equipment technology lags behind, resulting in the product quality, pass rate and production capacity cannot reach the market level;

Second, technological backwardness leads to a higher raw material cost for domestic manufacturers than for foreign manufacturers;

Third, the technology of domestic manufacturers is incomplete, and many technologies depend on foreign manufacturers.

Current Situation and Development Trend of China's optical fiber pre-fabricated rod Industry

From the time when all optical fiber was dependent on imports and only simple optical fiber processing can be performed, to the time when it became one of the world's largest optical fiber cable manufacturing and demand powers, china's optical fiber cable market has made great development in the past 30 years. According to statistics, China's cable market has accounted for 42% of the world's total, and five enterprises have entered the top 10 Global Cable companies. At the same time, China has made a major breakthrough in the core technology of the fiber optic prepaster, successfully breaking the technical blockout of foreign enterprises. In the future, as the pace of broadband network construction is further accelerated, China's optical fiber and cable industry will continue to develop, and it will go forward on the road of transformation and upgrading.

With the continuous advancement of the optical fiber network strategy and the continuous expansion of the optical fiber network, and with the support of the fiber-to-the-home and triple-play policies, the rapid growth of voice, data, video, and other services has promoted the rapid development and technological progress of optical fiber networks. At the same time, it has put forward higher requirements on the coverage and Stability of optical fiber networks, this will bring new development opportunities to the development of the optical fiber and cable industry, especially the fiber pre-fabricated rod industry. At present, China's optical fiber production enterprises should seize the opportunity and strive to improve the technical level of optical fiber pre-fabricated rods and enhance the international competitiveness of China's optical fiber industry.

Development Status of the fiber pre-fabricated rod Industry

The optical fiber pre-fabricated rod is an important basic material for the production of optical fiber cables. For the optical fiber cable industry, the technical level of the optical fiber pre-fabricated Rod plays a decisive role. At present, China's optical fiber enterprises need 60% ~ 70% depends on imports. Therefore, the localization and scale-up of fiber pre-fabricated rods are not only the development needs of China's optical fiber industry, but also the survival and development needs of domestic optical fiber enterprises.

In recent years, driven by the development of 3G, FTTH, three-in-one network, and IOT, China's optical fiber and cable industry has witnessed vigorous development. The application scope of optical fiber cables is constantly expanding, and the optical fiber communication network is constantly expanding. In particular, the bending of non-sensitive single-mode optical fiber (G.657) is suitable for intensive cabling in indoor narrow environments, making full use of the advantages of optical fiber, such as high bandwidth and low attenuation, is gradually becoming the first choice for optical fiber access network construction. In the face of such a development situation, the manufacture of fiber optic pre-fabricated rods becomes more important. The production of fiber pre-fabricated rods has become a bottleneck affecting the development of China's optical fiber industry. Developing new fiber pre-fabricated Rod Production Technology and rapidly increasing production capacity are the key to solving this problem.

Development Trend of the fiber pre-fabricated rod Industry

Currently, there are dozens of major Optical Fiber manufacturers in China, but there are not many enterprises capable of producing fiber pre-fabricated rods, such as changfei, fenghuo, Futong, hengtong, and Zhongtian, we have done a lot of work in the development and production of optical fiber pre-fabricated rods by using joint ventures between China and foreign countries, or by introducing technology. We have mastered the manufacturing technology of the pre-fabricated rods and improved the bulk production capability, however, there is still a big gap with the leading international level in terms of production efficiency, production scale, and cost control.

In terms of technology, the production of fiber optic pre-fabricated rods at home and abroad mostly adopts two-step process, that is, four basic Optical Rod Production technologies are used to manufacture the core rods, and different technology manufacturing outsourcing layers or direct casings are used outside the core rods. In China, four basic methods and their combinations are used to manufacture fiber optic pre-fabricated rods. With the strong support of China in recent years, domestic enterprises have developed rod Manufacturing Technology with independent intellectual property rights through cooperation with foreign enterprises and independent innovation, master or preliminarily master the rod manufacturing technology, and realize the industrialized production of the domestic fiber pre-fabricated rod. However, the scale of China's fiber pre-fabricated rod industry remains to be further improved. How to further reduce costs and participate in international competition is an important challenge to be solved. It is a long journey to build a Chinese premade stick brand, explore the international market, and win a place in the fierce market competition.

Opportunities for the development of the fiber optic pre-fabricated rod Industry

The market trend of optical fiber cables and pre-fabricated rods is affected by the international economic development situation, which is closely related to the development of the entire optical fiber network. However, with the expansion of optical fiber networks from backbone networks to access networks and man networks, as well as the continuous expansion of the user's resident network, it is bound to promote the gradual expansion of the construction scale of the optical network, the optical network market will inevitably develop rapidly.

3G drives the increasing market demand. 3g breaks the physical boundaries between the communication network and the Internet in the traditional sense, greatly improves the wireless access capability, and drives the development of fiber network construction. At present, backbone networks at all levels in China have been fully established over the years and can meet the needs of various communication services for a long period of time. However, there are few existing access networks that can be shared, in the next few years, China will become the fastest growing market in the 3G Industry, and the fiber optic cable used for basic network construction will also usher in a broad market, this will also generate a huge impetus for the development of the fiber pre-fabricated rod industry.
