Comparative Analysis of Two Technical Solutions for Expanding O-Band Services on Existing C-Band DWDM Systems
Apr 03 , 2026
Against the backdrop of rapid development in optical communication networks and explosive growth in data traffic, operators and enterprises often face the problem of insufficient capacity in existing C-Band (1525~1565nm) DWDM systems. On the one hand, the wavelength division channels occupied by the original C-Band services are nearly fully loaded; on the other hand, there is an urgent demand for ...
