在城域網建設(特別是長距離OTN光傳輸網)中, 波分復用設備尤其重要,DWDM密集波分復用設備具有遠距離、高帶寬的傳輸能力;CWDM粗波分復用設備具備較低的成本。
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,...
We look at the difference between CWDM vs DWDM including channels, frequencies, lasers, reach and bandwidth considerations.
DWDM, on the other hand, offers greater distance and capacity. It also offers a cost-effective “pay-as-you-grow” model. It’s suitable for long-haul transmissions, can be used with existing fiber optic cables, and is also protocol and bitrate independent; all of which makes DWDM an att...

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...
WDM承载方案有粗波分复用(CWDM)、密集波分复用(DWDM)以及中等波分复用(MWDM)、细波分复用(LWDM)。MWDM是重用了CWDM的前6波,将波长间隔压缩为7nm,左右偏移3.5nm扩展...支持12波25G,容量提升,可进一步节省光纤。 亿源通可为客户提供全系列WDM波分复用解决方案,包括最新的MWDM, LWDM 以及CWDM,DWDM产品。亿源通科技...

CWDM and DWDM all belong to the WDM technology. The difference is that they are in the spectrum of different channel spacing. CWDM have 16 band that from 1270 nm to 1610 nm, interval between each band to 20 nm. Generally use the DFB laser, its laser and filter device is cheaper. DWDM...
