What Is The Advantage Of The CWDM Multiplexer Module


CWDM is a low-cost WDM transmission technology for metro access layer. Principle, CWDM is the use of the optical multiplexer to different wavelengths of light signals multiplexed to a single optical fiber for transmission, at the receiving end of the link, with the optical demultiplexer fiber mixed signal is decomposed into different wavelengths signal, connected to the respective receiving apparatus.


CWDM modules include CWDM mux / demux module and CWDM OADM module. The most popular configuration of cwdm multiplexer module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux / demux module. 3 Single fiber or dual fiber connection for CWDM Mux / demux can be found. The Coarse Wavelength Division Multiplexing-CWDM Mux / demux can be a flexible plug-and-play network solution, allowing carriers and enterprise companies to cheaply implement point to point or ring based WDM optical networks.




CWDM most important advantage is the low cost of equipment. In addition, the CWDM Another advantage is that you can reduce the operational costs of the network. 220V AC power supply the CWDM equipment small size, low power consumption, easy to maintain, power supply, you can use. Because of its fewer number of wavelengths, so the board backup volume. 8 wave CWDM devices are no special requirements on the fiber, G.652, G.653, G.655 fiber can be used, and can take advantage of existing fiber optic cable. CWDM systems can significantly increase the transmission capacity of optical fiber, optical fiber resources utilization. The MAN construction are facing certain degree of tension or expensive leased fiber fiber resources. Typical coarse wavelength division multiplexing system can provide eight optical channels, in accordance with ITU-T G.694.2 specification can reach up to 18 optical channels.


The CWDM Another advantage is the small size and low power consumption. CWDM lasers without thermoelectric cooler and temperature control function, it is possible to significantly reduce the power consumption, such as DWDM systems each laser to about 4W power consumption, cooler CWDM laser consumes only 0.5W of power. CWDM system simplify the laser module such that the optical transceiver integrated module volume decreases, and the simplification of the structure of the device also reduces the volume of the device, saving room space. Compared with traditional TDM, CWDM rate and protocol transparency, which make it more adapted to MAN the development of high-speed data services.


MAN many different protocols and different rates business, CWDM provides a fiber at different rates, protocol transparent transmission channel, such as Ethernet, ATM, POS, SDH and CWDM transparency and drop multiplexing function allows the user directly to the upper and lower one wavelength, instead of converting the format of the original signal. That is, the light absorbing layer provided independent of the transmission structure of the business layer. CWDM has good flexibility and scalability. The for metro business terms, business flexibility, particularly in the business to provide the speed and the ability to be expanded as the business development is very important. CWDM technology user opened a business in one day or a few hours, but also with the increased volume of business, by inserting a new OTU board capacity expansion. Improve the quality of business. MAN CWDM system allows the optical layer recovery possible. Optical layer recovery recovery much more economical than electric layer. Taking into account the optical layer recovery is independent of the business and the rate, then the original own institutional system of protection features (such as Gigabit Ethernet), you can take advantage of CWDM to protect.


Due to the above advantages of CWDM technology, CWDM get more and more applications in the field of telecommunications, broadcasting, enterprise network, campus network.
