In this Letter multimedia transmission in an optical‐fiber network using a fast frequency hopping–code division multiple access scheme is discussed. The multirate one coincidence variable length frequency hop patterns have been generated and their auto‐ and cross‐correlation properties are studied. A series of multiple Bragg gratings in a single optical fiber has been proposed to implement the encoder and decoder. Bit‐error‐rate analysis assuming Gaussian approximation for the error probability has been carried out. The results of the numerical analysis reveal that this system can support up to 30 simultaneous users with two different data rates (e.g., 500 Mbps and 2 Gbps). It can be concluded from the results that the fast frequency hopping–optical code division multiple access system is capable of supporting multimedia applications. © 2002 Wiley Periodicals, Inc.
