摘要
分析比较了粗波分复用 (CWDM )技术与密集波分复用 (DWDM )技术的异同 ,总结了CWDM技术的优点与不足之处 ,针对CWDM系统扩容性差的缺陷 ,给出了目前的一些解决方案 :全波段CWDM、CWDM内嵌DWDM波长、提高单位通道传输容量。
The difference of the techniques between coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM) is compared and analyzed. Both the advantages and drawbacks are discussed. To cover the shortage of the scalability for CWDM, some solutions are put forward such as full spectrum CWDM, CWDM+DWDM, and improvement on the transmission rate per wavelength.
