| 摘要 |
The invention relates to an optoelectronic transmission arrangement for optical parallel connections. The transmission arrangement has: a first number (N) of electrical data channels that in each case transmit electrical input data; a second number (N+m) of optical transmitters, a transmitter in each case being able to convert the electrical signals of a data channel into optical signals, and the second number (N+m) being greater than the first number (N); a second number (N+m) of monitoring devices that are contained in the transmission arrangement and are in each case assigned to an optical transmitter; a control unit, which is connected to the second number (N+m) of monitoring devices and detects if an optical transmitter is not operating in accordance with a predefined operating specification, and a switch with a first number (N) of inputs and a second number (N+m) of outputs, the switch distributing the data of the first number (N) of electrical data channels between an identical number (N) of optical transmitters, at least one optical transmitter receiving no data and providing a redundant transmission channel. The control unit, for the case where an optical transmitter is no longer operating correctly, transmits a control signal to the switch and the latter switches over the data of the corresponding data channel to one of the redundant transmission channels in a manner dependent on said control signal. The invention furthermore relates to a corresponding optoelectronic reception arrangement.
