摘要
The present invention is a device for converting an RZ signal into a NRZ signal which contains an optical bistable device (5), where an output level of this device passing from a low level to a high level when an input power level crosses in an upward direction a first threshold, and returning to a low level when an input level crosses in a downward direction a second threshold below the first, the output (7) of the bistable (5) carrying the NRZ signal, and a device (2) for converting the RZ signal into a control signal of an output logic level of the optical bistable device (5) receiving the RZ signal, and delivering the control signal of the optical bistable device (5), this signal having a level above the first threshold when the RZ signal passes to 1 and which becomes lower at the second threshold only if the RZ signal passes to 0 and stays there for more than one bit time.
