APPLIANCE AND ARRANGEMENT FOR OPTICAL SIGNAL TRANSMISSION BY MEANS OF OPTICAL WAVEGUIDES |
摘要 |
An appliance for optical signal transmission using optical waveguides in explosion-hazard areas, in particular in underground mining, includes an optical transmitter, having an optical output interface for connection of an optical waveguide transmission path and having a device for limiting the light power. An arrangement for bi-directional optical signal transmission is also provided. In order to provide an appliance for optical signal transmission as well as an arrangement for bi-directional optical signal transmission in explosion-hazard areas, complying with the requirements for intrinsically safe operation of the transmission medium when separating or decoupling the transmission medium, the device for limiting the light power is a passive optical component which is connected in the optical signal path between the optical transmitter and the optical output interface. |
