8. Lates News
WDM technology can take advantage of the resources of the enormous bandwidth of single-mode fiber low-loss areas.
Type according to the lightwave frequency for each channel (or wavelength), the low-loss window of the optical fiber is divided into a certain channel, as the lightwave carrier signal, using a WDM (wave) on the transmit side, the different provisions The carrier of the wavelength of the signal light combined into the single optical fiber for transmission.
At the receiving end, separated from the carrier by a wavelength division multiplexer (demultiplexer) these different wavelengths of light to carry different signals. Since the different wavelengths of the optical carrier signal can be regarded as independent of each other (without regard to fiber nonlinearity), thereby multiplex transmission of the multiplexed optical signal in an optical fiber can be realized.
Fiber access technology
Optical fiber access network is the information superhighway "last mile". High speed, to meet the needs of the public, not only have a broadband backbone transmission network, user access is the key, optical fiber access network high-speed information flow into millions of households the key technologies to achieve information transmission. In the fiber-optic broadband access, fiber reaches the different positions, there FTTB, of FTTC, FTTCab and FTTH different applications, collectively FTTx.FTTH (FTTH) is the ultimate way of fiber-optic broadband access, which provides all-optical access, therefore, can take advantage of fiber optic broadband characteristics, to provide users with unrestricted bandwidth needed to fully meet the demand for broadband access. At present, the domestic technology can provide users with bandwidth of FE or GE is an ideal access for users of large and medium-sized enterprises.
The development of optical fiber communication technology
In recent years, as technology advances, telecommunications management system reform, as well as step-by-step full liberalization of the telecommunications market, the development of optical communications again presented the booming new situation, the following major development in the field of optical fiber communication hot spots for a simple above and prospects, to the development of ultra-high-speed system, the evolution of the large-capacity WDM system.
From the point of view in recent years, the development of optical communications, building one of the largest transparent, highly flexible and large-capacity national backbone optical network not only for the future of the National Information Infrastructure (NII) has laid a solid physical basis, but also on China's information industry of the next century and take-off of the national economy and national security is extremely important strategic significance. The development of optical fiber communication industry is an irreversible trend of modern communication.
