In order to develop a driver circuit (2) of, and a method for supplying voltage/current to, at least one of at least two optical transmission elements (8-1, 8-2, 8-3) which are intended to transmit at least one optical signal, in particular light, for the purpose of transmitting data, in particular at least two electrooptical transducers, for example at least two light-emitting diodes or at least two lasers, for instance at least two semiconductor lasers, in such a manner that the reliability of the optical transmission element (8-1, 8-2, 8-3) and/or the electrooptical interface module is significantly increased, it is proposed that, in particular in the event of the active optical transmission element (8-1, 8-2, 8-3) failing, at least one control unit (18) which is assigned to at least one driver circuit (2) be used to change over between the at least two outputs (19, 20, 21), which are designed to connect the optical transmission elements (8-1, 8-2, 8-3), in such a manner that an optical transmission element (8-1, 8-2, 8-3) is respectively in the activated state. |
