A multiplexer combines, or multiplexes, several lower-bandwidth streams of data into a single beam of light. An "add-drop" multiplexer also has the capability to "add" one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same time can extract or "drop" other low-bandwidth signals, removing them from the stream and redirecting them to some other network path.
