DWDM (dense wavelength division multiplexing) is the preferred technology in today's optical fiber applications, but the price is relatively expensive. In comparison, CWDM (sparse wavelength division multiplexing) is a low-cost WDM transmission technology for the access layer of man. Now ETU-Link will introduce 10g SFP+ CWDM / DWDM optical module. 10G SFP+ CWDM optical module: 10G SFP+ CWDM optica...
