18 Channel CWDM Mux Demux 1270-1610NM Equipment Sparse Wavelength Division
CWDM Mux/Demux increases fiber capacity in either 4, 8, 16 or 18 channel increments. By increasing the channel spacing between wavelengths on the fiber, CWDM allows for a simple and affordable method of carrying up to 18 channels on a single fiber. CWDM channels each consume 20 nm of space and together use up most of the single-mode operating range. The CWDM wavelengths most commonly used are the eight channels in the 1470 to 1610 nm range. CWDM Mux/Demux allows any protocol to be transported over the link, given it’s at the specific wavelength.
