What's WDM, what's CWDM/DWDM, CWDM vs DWDM, what’s the difference between them? What are their advantages and disadvantages? This post has the answer to all.
CWDM和DWDM之间的区别 :编号CWDMDWDM 1 CWDM系统每根光纤的有效波长少于8个。 DWDM系统每根光纤有8个以上的有效波长。 2 CWDM是由波长定义的。 DWDM是由频率定义的。 3 与之相比,CWDM的容量较低。 相比之下,DWDM有更高的容量。 4 CWDM的成本低。 DWDM的成本高。 5 CWDM的通信距离短。 DWDM有长距离的通信...
As their names suggest, the words “coarse” and “dense” reveal the difference in channel spacing. CWDM has a wider spacing than DWDM. It is able to transport up to 16 wavelengths with a channel spacing of 20 nm in the spectrum grid from 1270 nm to 1610 nm. But DWDM can carry 40,...
CWDM VS DWDM Difference Wavelength Spacing CWDM can transport up to 16 wavelengths with a channel spacing of 20 nm in the spectrum grid from 1270 nm to 1610 nm. While DWDM can carry 40, 80, or up to 160 wavelengths with a narrower spacing of 0.8 nm, 0.4 nm, or 0.2 nm from the wav...
