The difference between DWDM and OTN

In today’s rapidly developing optical communication, DWDM (dense optical wavelength multiplexing) and OTN (optical transport network) technologies play a vital role in backbone networks. Although they have similarities, there are also many differences. A deep understanding of these differences is important for building efficient and reliable optical communication networks. 1. The concept is different (1)… Continue reading The difference between DWDM and OTN

Why DWDM?

From both technical and economic perspectives, the ability to provide potentially unlimited transmission capacity is the most obvious advantage of DWDM technology. The current investment in fiber plant can not only be preserved, but optimized by a factor of at least 32. As demands change, more capacity can be added, either by simple equipment upgrades… Continue reading Why DWDM?
