Abstract
An optical repeater device of the present invention comprises: a preamble compensating circuit, for taking out a normal data signal from burst signals propagating through a communication transmission path, and for adding a preamble signal before and/or after the data signal. Furthermore, the preamble compensating circuitcomprises: a detector circuit, for inputting the burst signal, and for outputting only the normal data signal; a buffer circuit, for storing the data signal output from the detector circuit, and for outputting thereof; a preamble signal generation circuit, for outputting at least one type of the preamble signal; and an data output select circuit, for outputting the data signal at the time of the data signal input from the buffer circuit, and for outputting the preamble signal from the preamble signal generation circuitat any other time thereof.
