Abstract
The present invention discloses an optical fiber communication system for an optical network in which a plurality-of types of communication terminal equipments are connected to one another via optical fibers, the optical fiber communication system, being consisting of the steps: conducting wavelength multiplexing using at least three wavelengths, allotting a first optical wavelength to a packet switched communication of a distribution control system, allotting a second optical wavelength to a line switched communication of a time division multiplexing system, allotting the residual optical wavelength to a line switched communication by an optical, wavelength allotment system, and conducting a control of the line switched communication of the time division multiplexing system using the second optical wavelength and the line switched communication by the optical wavelength allotment using the residual optical wavelength, this control being conducted by using the packet switched communication using the first optical wavelength. The present invention further discloses an optical network having an optical network control unit to which the optical fiber communication system is applied, an optical network having no optical network control unit, a terminal equipment forming the optical network, and an optical network control unit.
