DWDM – Dense Wavelength Division Multiplexing

The development of erbium doped fibre amplifiers has allowed channel spacing of 0.8nm in the 1550nm range. This enables many more wavelengths to be multiplexed onto a single fibre. In simple terms, DWDM systems shine different colours of light down the optical fibre, with each colour or wavelength capable of conveying a separate datastream. Therefore, a DWDM system with 200 channels would be capable of carrying 200 times the amount of data than a single wavelength fibre.
