To win the market is to reduce the cost of optical fiber

 From a global perspective, the fiber industry has developed into a mature stage, into the cost competition stage. The domestic enterprise to win in the fiber of low-cost competition, focus efforts in two aspects: one is the rod making technology, which enhance the deposition rate; another is the establishment of industrial complex, reduce the cost of raw materials.
Optical fiber market has been affected by two major favorable factors, from the telecom market, the largest of the access network drive. For radio and television sector, because of the network, including backbone core network, metropolitan area network are not deployed, now the focus is on the network is built, the next step is the climax of the access network.
The light dependence on imports is difficult to reduce the cost of
FTTH is divided into two parts, one part is active, one is passive. The passive part of investment is relatively large, but the life is long, because the service life of the optical cable is at least 20 years. The passive part of the investment to be particularly careful, build it is the key of network deployment.
Because the 3G investment and operators in the attention of FTTH, 2009 domestic fiber market growth in 50% ~ 60%, reach about 70000000 core km dosage, 80% is included as a part of export products. This year the whole industry will maintain a growth, but the growth rate will decline, is expected to be around 10%. Optical fiber market is still in rapid development, from a long-term perspective, later also to prevent excess capacity.
But the optical fiber preform is not excessive, until now still need to import 80%. This is mainly because the higher cost of production of domestic preform, competitiveness is not strong.
There are two reasons, one is the technology, is mainly the low deposition rate, rod making speed is the key, the foreign company is about 5 times of our. It is from the core of view, from the external cladding is far more. Two is the high cost of raw materials. Four chlorinated silicon raw material of light is a by-product of polysilicon production, because of the foreign fiber enterprises are complex, more cooperation with upstream polysilicon plant, four chlorinated silicon cost is very low. Fiber domestic enterprises and polysilicon manufacturers and generally do not form a cooperative and United, a by-product of polysilicon manufacturers as waste emissions. Now there have been some of the union, but the association is not big, union is to further the establishment of the industrial chain, take the raw material four chlorinated silicon costs down.
Therefore, the domestic enterprise to win in the fiber of low-cost competition, focus efforts in two aspects: one is the rod making technology, which enhance the deposition rate; another is the establishment of industrial complex, reduce the cost of raw materials.
Market competition is the key to cost
From a global perspective, the fiber industry has developed into a mature stage, the market competition is no longer the splicing technology stage, but into spell cost stage, now cost is the dominant. Domestic enterprises are now various kinds of optical fiber can be produced, but the cost is a problem.
After years of development, many patents in the field of optical fiber fails, a new patent rarely, have no technical barriers, now the domestic fiber quality compared with foreign countries there is no big difference. But the optical fiber preform is mainly from foreign enterprises, domestic enterprises only drawing.
Convergence will bring greater demand for fiber market, and cost requirements will be lower. How to effectively reduce the cost? Now the emergence of a new 80 μ m cladding diameter standard, and before is 125 μ M. 80 μ m fiber will become more fine, before this diameter was not included in the specification, now the international standard, the domestic enterprise has made products. For FTTH, of course, fiber finer the better, but small after drawing length will increase, the cost can be reduc
The optical fiber compared with the past, quality is the same, is coupled up more trouble, but now the coupling technology has been very mature, can do.
To use fiber finer, requires a standard specification. Due to the large sum, test pilot, domestic FTTH ODN (optical distribution network) standard has not come out. But with seven ministries "on the promotion of broadband fiber opinions" issued, the operator more involved in FTTH, ODN standard is expected to accelerate the formulation. Now our a pressing matter of the moment is to catch the ODN standard. At present, Shanghai optical network has been doing related work, but in its standard, 80 μ m is not considered
After years of development, especially after the industrial recession, domestic fiber market has been integrated, now, domestic manufacturers can do optical fiber preform 6, they all have more than 10000000 core production capacity, enterprises do not have the same capacity is not enough.
At the cost of the dominant phase, foreign fiber enterprises in the future will gradually take the exit strategy, but they tend to stick to the Enterprise Holdings, to master the price right upper light. Therefore, in the future how many bars need to be imported, is hard to predict.
