Coarse Wavelength Division Multiplexing (CWDM) is a wavelength multiplexing technology for city and access networks. Transmission is realized using 18 channels with wavelengths between 1270 nm and 1610 nm. Due to the channel spacing of 20 nm cost-effective lasers can be used. The channel width itself is 13 nm. The remaining 7 nm is designed to secure the space to the next channel. CWDM highlights Up to 18 CWDM wavelength over one pair of fiber CWDM channel spacing 20 nm, 1270 nm to 1610 nm Distances up to 120 km Cost-effective WDM solution Scalable by hybrid CWDM/DWDM - perfect solution for your investment
