In China,In reforming and opening and the practice that economy builds, people realizes the value that develops infrastructure adequately,
"Want rich, build a road first "
That means Road and Internet communication should be develop first.communication industry develops, national economy develops.
Demand for the global fiber optic cable market is still rising steadily. As FTTx gains favor from more and more telecom operators, the global fiber optic cable market demand is steadily increasing year by year. In 2016, the global demand for fiber optic cable has exceeded 400 million core kilometers. According to forecasts, the demand for fiber optic cable will maintain steady growth in the next 4-6 years, with a growth rate of around 15%. It is predicted that by 2025, the global demand for fiber optic cable will reach 1565 million core kilometers. Driven by the rapid growth of global Internet traffic, fiber optic cable as an infrastructure construction will remain the focus of construction.
The Big explosion period and great development of Optical Fiber Communication will occur
in Central,South America and southeast Asia in the next five years.communication industry develops, national economy develops.
First developed in the 1970s, fiber-optics have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world.
After years of development, the major development areas of the global optical communications market are concentrated in China, the United States, Japan, South Korea and the European Union.
Analysis of major development areas of the optical communication market
In the United States, the country with the most developed optical communication industry has advanced optical communication technology, but the actual optical communication network construction lags behind Japan and South Korea. With the government's vigorous promotion of broadband construction, the FTTH industry has developed rapidly.
Japan, a major optical communications country, is a global leader in fiber access, and Japanese optical communications companies account for more than 70% of the Japanese domestic market.
The huge share has driven the construction of Japan's optical communications and the growth of its export economy.
South Korea, the main optical communication market in the Asia-Pacific region, has a FTTH coverage rate of 92%.
Local companies such as Samsung, LG, and SK Telecom have advanced technologies and equipment in the development of optical communications industry, and have a certain influence on a global scale.
In Europe, the development of optical communication industry in the region is mature, and the market maintains stable growth. The penetration rate of optical communication networks is also relatively high, and the development of FHHT is uneven. The development level of more advanced countries such as Sweden and Denmark is relatively high. The gap is relatively large.
China, at present, China's "Broadband China" strategy and 4G construction have all been promoted. The second phase of 5G technology R&D trials has also begun. The "Internet +" strategy has also risen to become the national strategy, FTTX construction and Internet-driven information consumption. Great changes have been brought to the whole society, which has greatly promoted the development of the optical communication industry and brought unprecedented opportunities for optical communication. In 2016, as the first year of the “13th Five-Year Plan”, the optical communication market was strong and the industry was promising. 2017 is still the best opportunity for the development of China's optical communications market. In general, China's optical communications has developed strongly and has become the world's largest broadband country, but its network coverage is far lower than that of developed countries and regions. The FHHT market is developing at a high speed, forming a series of competitive enterprises, such as Huawei. ZTE, Fiberhome Communications, Changfei, Hengtong, etc.
We expect that the explosion period and great development of this industry will occur
in central and South America and southeast Asia in the next five years.
We have seen the trend of economic development in these areas in recent years And the government is building infrastructure.
Can say so, communication industry develops, national economy develops.
The decline of traditional telecom services and business models has been unable to reverse, and transformation has become an inevitable choice; as copper prices have risen sharply, the continued use of copper raw materials has increased the bandwidth cost, while the prices of fiber optic cables and optical transceiver modules have gradually decreased; The Internet service, including future IPTV, has put forward new requirements for bandwidth, so the speed of bandwidth has become an urgent requirement. At the same time, the convergence of services, including broadband Internet access, VOIP and other services, has led to the inevitable choice of fiber optics to solve user needs.
Each effect that contributes to attenuation and dispersion depends on the optical wavelength. There are wavelength bands (or windows) where these effects are weakest, and these are the most favorable for transmission. These windows have been standardized, and the currently defined bands are the following:
Band | Description | Wavelength Range |
---|---|---|
O band | original | 1260 to 1360 nm |
E band | extended | 1360 to 1460 nm |
S band | short wavelengths | 1460 to 1530 nm |
C band | conventional ("erbium window") | 1530 to 1565 nm |
L band | long wavelengths | 1565 to 1625 nm |
U band | ultralong wavelengths | 1625 to 1675 nm |
