Chapter 4 covered the basics of linear fiber-optic signal transport. These are applicable to situations in which just a single optical signal is sent through each fiber. Fibers, however, are capable of carrying multiple independent optical signals on different wavelengths simultaneously with a minimum of mutual interaction. The general term for such shared use of fiber is wavelength division multiplexing (WDM).
