A WDM system runs on the multiplexer at the transmitter to participate the signals together, along with a demultiplexer in the receiver to separate them apart. With all the right form of fiber it's possible to use a device that does both simultaneously, and may work as an optical add-drop multiplexer. In Fiberstore,I find the WDM including CWDM and DWDM equipment.Now,we come together to find out what is CWDM multiplexer demultiplexer.
Coarse wavelength division multiplexing (CWDM) is a technique of combining multiple signals on lasers at various wavelengths for transmission along fiber optic cables, so that the number of channels is under in dense wavelength division multiplexing (DWDM) but more than in standard wavelength division multiplexing (WDM).
CWDM multiplexer demultiplexer Module can be a flexible, low-cost solution that allows the expansion of existing fiber capacity. In conjunction with highly reliable passive optics certified for environmentally hardened applications, the CWDM Mux/Demux lets operators use available fiber bandwidth in local loop and enterprise architectures.
The CWDM multiplexer/demultiplexer can be a universal device effective at combining nine optical signals into a fiber pair. It's built to support a broad range of architectures, which range from scalable point-to-point links or two fiber-protected rings.
The CWDM Mux/Demux was created to interoperate with both Wave Ready line of transponder and optical regenerator solutions as well as CWDM transponders and small form-factor pluggables (SFPs) used in accessible transmission equipment. With vast amounts 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, soon is anticipated being extended to 16 within the full spectrum wavelength. And launch from the CWDM system is thought to have a comprehensive network management function, can to equipment remote monitoring, configuration, and also the alarm. In addition, the CWDM makes the card into the recent popular GPON (gigabit PON) system. Recently, the American time warner has signed a long-term purchase agreement, includes: WavSystem of CWDM module will probably be utilized in The big apple, Ohio, the deployment of gigabit metropolitan area network.
When it comes to optical fiber, the current us lang - progression 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 2 kinds of suited to CWDM fiber of low water content, the fiber maximum eliminate residual fiber of OH - ions, lessen the transmission loss. The usage of these optical fiber, is expected to greatly promote the wide popularity of CWDM technology, mainly in the application of long-distance communication.
When it comes to optical fiber, the Japanese 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. In addition, corning, companies for example lucent also produce optical fiber low water content. Using these optical fiber, is expected to greatly promote the wide popularity of CWDM technology.
