DWDM (Dense Wavelength Division Multiplexing) is the technology of choice for today's fiber applications, but the price is more expensive. Compared to the CWDM (Coarse Wavelength Division Multiplexing) low cost, low-cost technique for transmitting WDM metro access layer. The following communication is easy to introduce daylight 10G SFP + CWDM / DWDM optical module.
10G SFP + CWDM optical module:
10G SFP + CWDM optical module is an optical CWDM module, commonly used with single-mode fiber. Such an optical fiber module to conserve resources by using CWDM technology, can significantly improve the network flexibility, economy and reliability, and the power consumption of such an optical module is very small, a 10G SFP + 12.5% DWDM optical module.
10G SFP + DWDM optical module:
10G SFP + DWDM optical module is a relatively rare domestic high-rate, large-capacity optical dense wavelength division multiplexing module, commonly used with single mode fiber up to 80km transmission distance, for long-distance data transmission. This optical module may meet the greatest extent possible the needs of large capacity and ultra-long haul transmission, providing stable operation and guarantee for future multi-service network upgrade and expansion, also supports a variety of networking mode, you can also perform wavelength between nodes scheduling, with expansion capacity and easy, flexible service access, a number of advantages of high reliability and high bandwidth utilization.
