DWDM Wavelengths Chart
介紹:
DWDM嘅, which stands for Dense Wavelength Division Multiplexing, is a technology used in optical communication networks to increase the transmission capacity over a single optical fiber. It achieves this by simultaneously transmitting multiple optical signals of different wavelengths on the same fiber. To effectively use DWDM technology, it is important to understand the wavelengths used and their corresponding applications. This article provides a comprehensive DWDM wavelengths chart to facilitate a better understanding of this technology.
