Abstract:
An optical communication method in which the modes of two electric buses connected through optical fibers, a plurality of nodes being connected to said buses, are brought into agreement, comprising the steps of:observing the modes of said electric buses and the modes of said optical fibers while said electric buses are not being driven (OFF mode);maintaining optical output from the buses that are being driven to said optical fibers while one or both of said electric buses are being driven (ON mode) by the nodes connected thereto;maintaining electric output to the electric bus of the side to which light is inputted to drive the bus without observing the modes of said buses while light is being inputted from said optical fibers; andstopping said optical and electric outputs to restrict said electric buses from being driven when the buses are no longer driven by said nodes.
