How to choose CWDM-DWDM equipment in optical transmission network
In the construction of metropolitan area networks (especially long-distance OTN optical transmission networks), wavelength division transmission equipment is particularly important. DWDM dense wavelength division multiplexing equipment has long-distance and high bandwidth transmission capabilities; CWDM coarse wavelength division multiplexing equipment has relatively Low cost. So if you choose the right wavelength division multiplexing equipment to build […]
