Subcarrier Multiplexing (SCM) is a method for combining (multiplexing) many different communications signals so that they can be transmitted along a single optical fiber. SCM (also known as SCMA, SubCarrier Multiple Access) is used in passive optical network (PON) access infrastructures as a variant of wavelength division multiplexing (WDM).
