CWDM modules include CWDM mux / demux module and CWDM OADM module. The most used 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 is 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 significant advantage may be the low cost of kit. In addition, the CWDM An additional is you can decrease the operational costs of the network. 220V AC power supply the CWDM equipment small size, low power consumption, an easy task to maintain, power supply, you should use. Due to its fewer number of wavelengths, therefore the board backup volume. 8 wave CWDM tools are no special requirements about the fiber, G.652, G.653, G.655 fiber can be utilized, and will take advantage of existing fiber optic cable. CWDM systems can significantly raise the transmission capacity of optical fiber, optical fiber resources utilization. The person construction are facing certain level of tension or expensive leased fiber fiber resources. Typical coarse wavelength division multiplexing system can offer eight optical channels, in accordance with ITU-T G.694.2 specification can reach up to 18 optical channels.
The CWDM An additional advantage may be the small size and low power consumption. CWDM lasers without thermoelectric cooler and temperature control function, it's possible to significantly decrease the power consumption, such as DWDM systems each laser to around 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, as well as the simplification with the structure with the device also decreases the volume of these devices, saving room space. In comparison with traditional TDM, CWDM rate and protocol transparency, which can make it more adapted to MAN the introduction of high-speed data services.
MAN a variety of protocols and different rates business, CWDM supplies 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 right to top of the and lower one wavelength, instead of converting the format from the original signal. That's, the sunshine absorbing layer provided in addition to the transmission structure of the business layer. CWDM has good flexibility and scalability. The for metro business terms, business flexibility, mainly in the business to offer the speed and the ability to be expanded since the business development is vital. CWDM technology user opened a company in a day or a few hours, but additionally with the increased volume of business, by inserting a brand new OTU board capacity expansion. Increase the quality of economic. MAN CWDM system allows the optical layer recovery possible. Optical layer recovery recovery far more economical than electric layer. Taking into consideration the optical layer recovery is in addition to the business and also the rate, then your original own institutional system of protection features (including Gigabit Ethernet), it is possible to take advantage of CWDM to guard.
As a result of above features of CWDM technology, CWDM acquire more plus more applications in the field of telecommunications, broadcasting, enterprise network, campus network. Fiberstore provide not just provide cwdm multiplexer and CWDM OADM module also provides other kinds of transceivers. Your option is our confidence. Welcome to fiberstore buy fiber transceivers.
