CWDM(Coarse wavelength division multiplexing) multiplexer demultiplexer Developing

A WDM system uses a multiplexer on the transmitter to participate the signals together, plus a demultiplexer in the receiver to split them apart. With the right form of fiber it's possible to use a device that does both simultaneously, and will be an optical add-drop multiplexer. In Fiberstore,I've found the WDM including CWDM and DWDM equipment.Now,we interact to understand what exactly is CWDM multiplexer demultiplexer.

Coarse wavelength division multiplexing (CWDM) is a technique of combining multiple signals on laser beams at various wavelengths for transmission along fiber optic cables, such that the number of channels is less than in dense wavelength division multiplexing (DWDM) but more than in standard wavelength division multiplexing (WDM).

CWDM multiplexer demultiplexer Module is really a flexible, low-cost solution that permits the development of existing fiber capacity. Along with highly reliable passive optics certified for environmentally hardened applications, the CWDM Mux/Demux lets operators make full use of available fiber bandwidth in local loop and enterprise architectures.

The CWDM multiplexer/demultiplexer is really a universal device able to combining nine optical signals into a fiber pair. It's built to support an extensive range of architectures, including scalable point-to-point links or two fiber-protected rings.

The CWDM Mux/Demux was created to interoperate with the Wave Ready distinct transponder and optical regenerator solutions along with CWDM transponders and small form-factor pluggables (SFPs) utilized in accessible transmission equipment. With billions of field operating hours, the industryleading optical multiplexing technology offers unparalleled reliability and leading-edge performance.

CWDM Module Developing:

America's CWDM module supports eight CWDM channel, in the near future is predicted to be extended to 16 inside the full spectrum wavelength. And launch with the CWDM system is thought to possess a comprehensive network management function, can to equipment remote monitoring, configuration, as well as the alarm. Furthermore, the CWDM has made the credit card to the recent popular GPON (gigabit PON) system. Recently, the American time warner has signed a long-term purchase agreement, includes: WavSystem of CWDM module is going to be utilized in The big apple, Ohio, the deployment of gigabit metropolitan area network.

With regards to optical fiber, the present us lang - development of full wave fiber and corning SMF28 - e fiber (g. 652 c) basically eliminated the water peak attenuation and macro bending loss, as well as other properties with conventional single-mode g. 652 optical fiber; Japan introduced two kinds of suitable for CWDM fiber of low water content, the fiber maximum eliminate residual fiber of OH - ions, reduce the transmission loss. The use of these optical fiber, is anticipated to greatly promote the wide rise in popularity of CWDM technology, mainly in the use of cross country communication.

When it comes to optical fiber, japan launched two suitable for CWDM fiber of low water content. The fiber within the utmost reduction of fiber OH ions residue, lessen the transmission loss. Furthermore, corning, companies including lucent also produce optical fiber low water content. The use of these optical fiber, is predicted to greatly promote the wide interest in CWDM technology.
