What is the Advantage of the CWDM Multiplexer Module?

 

CWDM is a low-cost WDM transmission technology for metro access layer. Principle, CWDM may be the utilization of the optical multiplexer to different wavelengths regarding signals multiplexed with a single optical fiber for transmission, at the receiving end from the link, using the optical demultiplexer fiber mixed signal is decomposed into different wavelengths signal, coupled to the respective receiving apparatus.

 

CWDM modules include CWDM mux / demux module and CWDM OADM module. Typically 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 are available. 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 indicate point or ring based WDM optical networks.

 

CWDM most critical advantage will be the inexpensive of kit. Furthermore, the CWDM An additional advantage is that you could decrease the operational costs of the network. 220V AC power supply the CWDM equipment small size, low power consumption, easy to maintain, power, you can use. Due to its fewer variety of wavelengths, and so the board backup volume, 8 wave CWDM products 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 is facing certain degree of tension or expensive leased fiber fiber resources. Typical coarse wavelength division multiplexing system can provide eight optical channels, according to ITU-T G.694.2 specification can reach up to 18 optical channels.

The CWDM An additional advantage will be the small size and low power consumption. CWDM lasers without thermoelectric cooler and temperature control function, it's possible to significantly reduce the power consumption, and such as DWDM systems each laser to about 4W power consumption and cooler CWDM laser consume only 0.5W of power. CWDM system simplify the laser module so that the optical transceiver integrated module volume decreases, and also the simplification of the structure with the device also cuts down on the amount of these devices, 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 a variety of protocols and different rates business, CWDM offers a fiber at different rates, protocol transparent transmission channel, such as Ethernet, ATM, POS, SDH and CWDM transparency and drop multiplexing function permits the user right to top of the reducing one wavelength, rather than converting the format from the original signal. That's, the sunshine absorbing layer provided in addition to the transmission structure with the business layer. CWDM has good flexibility and scalability. 

 

For metro business terms, the business flexibility, especially in the business to supply the pace and also the ability to be expanded as the business development is vital. CWDM technology user opened a business in a single day or a few hours, but additionally using the increased level of business, by inserting a new OTU board capacity expansion. 

 

Enhance the quality of economic. MAN CWDM system permits the optical layer recovery possible. Optical layer recovers a lot more economical than electric layer. Taking into account the optical layer recovery is independent of the business as well as the rate, then your original own institutional system of protection features (for example Gigabit Ethernet); it is possible to take advantage of CWDM to safeguard.

 

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

 

Sopto provide not just provide CWDM multiplexer and CWDM OADM module now offers other types of transceivers. Your decision is our confidence. Welcome to Sopto buy fiber optical transceivers.
