Domestic optical communications technology research and development process of slow upstream
Optical Fair has been used for more than one month, but Bo meeting various eye exhibits still let people indulge in elaborating on. Optical fiber level, according to the communication world report concern is the balefire communication, flying, photoelectric and others have on-site display of their optical fiber preform, at present several domestic mainstream fiber manufacturers in the optical fiber preform capacity are achieved a breakthrough, subsequent expansion plan, also in the steady implementation. Optical fiber preform technology breakthrough of our country fiber-optic cable industry has become another milepost.
In the optical communication upstream technology research and development, the domestic enterprises most prudent, hand capital limited, difficult to support larger capital investment, on the other hand, the lack of adequate technical accumulation, in the breakthrough in core technology have great difficulty. Overall, many of the domestic optical communication enterprises in upstream of the core technology enthusiasm still not tall, has led to a number of core technology research and development progress is slow.
The field of high-end difference
In addition to the traditional areas of the device, module products, the current exhibition vendors show 40G/100G optical module product still attracted many eyeball. Since last year, the 100G market is arisen, for the 100G industry brings bigger urge action. Data shows, first half of this year 100G optical device product appeared to demand exceeds supply situation, many systems equipment manufacturers limited by 100G optical device supply is insufficient, affected its 100G product shipments. Many domestic and foreign optical module manufacturers demonstrated its 100G optical module product, it is understood, many optical module product is still not mature, and overseas related optical module manufacturers still have certain difference.
From this exhibition, Suoersi photoelectric display 40G SFP+LR4andSR4, 40G CFP FR/LR4/ER4, 100G LR4 three products, while ColorChip showed 40GBASE-LR4 QSFP+ optical transceiver module, used mainly for data intensive applications, the transmission distance from 100m to 10km. At the same time, Mitsubishi Motors, Hisense broadband is easy to fly and other manufacturers also showed its 40G optical module and optical module sample 100G new.
Whether it is from the development trend of the technology, or the future of the focus of the market analysis, for the 100G and data centers, the future market penetration will be optical device to the input focus. Undeniable, the devices in the core technology reserves, the introduction of the 100G optical device technical content is still not high, and there is still a wide gap between overseas manufacturers. A personage inside course of study points out, domestic manufacturers are still going to follow a course, independent innovation ability in.
With the end of optical communication products, profit shrink further, rely on the traditional scale expansion is more and more difficult to gain a foothold in the market, for many domestic national enterprises exists bigger challenge, to high-end products fields, has become have the choice to do. At present in the highly operator Jicai, market competition is very intense, PON equipment prices continue to decline, an equipment business experts also revealed PON chip prices have reached bottom, the cost has dropped it down, which led directly to the profit of the manufacturer to shrink further optical devices. In the high-end technology to achieve further development, it needs to consider how to reduce the difference between manufacturers and overseas.
