摘要

The optical device (100) has an electric line (120) that is provided to transmit electric signals. A monitoring unit (124) is provided for monitoring signal transfer over electric line. A detection unit is provided for detecting an actual value of property of transmitted signal. A comparison unit is provided for comparing actual value with reference value. An independent claim is included for a method for operating optical device.
