Abstract
A device for storing information in an optical fiber transmission system, the storage of information, in particular in the form of digital data, being provided by creating at least one circulating memory using the optical fiber connecting terminals together as delay line. The transmissions takes place at a first wave length and each circulating memory uses a particular wave length, different from that of the other memories and from the transmission wave length. Each memory comprises, in a first terminal, a light source, a detector and a multiplexer for coupling with the connecting optical fiber and, in the terminal which is coupled thereto, a dichroic mirror selectively reflecting the wave lengths of the circulating memories and transmitting the other wave lengths.
