The subject matter described herein is directed to an apparatus and a method for reduction of bit errors in continuous data transmission via a data transmission medium, the apparatus having a monitoring unit for monitoring of transceiver parameters of at least one transceiver transmitting said data and/or medium parameters of said data transmission medium and a calculation unit for predicting a time and a duration of an occurrence of at least one event affecting a bit error rate of said continuous data transmission depending on the monitored parameter; and a control unit for throttling a bandwidth of a data switch connected to said transceiver during the predicted duration of the event for bit error reduction.
