Abstract
A network architecture is presented for a fiber optic frequency hopping multiple access (FO-FHMA) communication system. It is shown that the network, in addition to providing an independent (from other users) and asynchronous access to the optical fiber channel for the network subscribers, effectively utilizes the available bandwidth when the optical channel is sparsely utilized. In this arrangement the network users employ pseudorandom codes to frequency modulate the optical signal on the fiber bus using an optical pulse modulator. 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. It is demonstrated that the system may easily be implemented with the aid of a number of available optical components and standard frequency hopping transmitter and receive.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
