ABSTRACT:
A process is indicated for the bidirectional transmission of digital data through a glass fiber, whereby the bits from data to be transmitted are compressed by a factor >2 into bursts, in packages of equal quantities, without changing the transmission rate. The bursts in one direction of the transmission are sent by an emitter station through a glass fiber to the other station, during the pauses between the bursts in the other transmission direction. Independent external pulse generators are used at both ends of a glass fiber to determine the transmission rates of the stations. If the frequencies of the two pulse generators deviate from each other, the bursts of the data flowing at the lower transmission rate are displaced with respect to the bursts of the other flow of data, by the width of one bit of the pertinent continuous flow of data. The displacement of the bursts is communicated to the respective receiver by at least one information bit corresponding to the burst preceding the first burst to be displaced.
