FIBER OPTIC FREQUENCY HOPPING MULTIPLE ACCESS COMMUNICATION-SYSTEM

In this letter we present a network architecture for a fiber optic frequency hopping multiple access (FO-FHMA) communication system. In this arrangement the network users employ pseudorandom codes to frequency modulate the optical signal on the fiber bus using an optical phase modulator. This approach provides an efficient access to the fiber optic bus for the network subscribers. A balanced optical phase discriminator followed by a standard frequency dehopping receiver are used to decode the user provided information at a desired point on the fiber bus.
