Data transmission system, especially optical system, for modification of transmission parameters depending on bit error rate measured at the receiver.

摘要

This transmission system, including sending-end equipment (1) and receiving-end equipment (2) is such that it includes means for evaluating the error rate on reception, and means (7) for control of one or more parameters characterising the sending-end equipment and/or the receiving-end equipment, on the basis of the error rate thus evaluated, in such a way as continuously to optimise this parameter or these parameters in the light of the real performance of the transmission system. <IMAGE>
