Ultra-small analog fibre-optical link for interference-free antenna signal transmission

The paper describes the development and design of an analog fibre-optical link for general RF signal transmission in reverberation (mode stirred) chambers, shielded rooms or - in general - through fields to be measured (not to be distorted). Its outstanding characteristic is the small size of the optical transmit unit of 14×14×20mm³ along with its optical power supply enabling an unlimited operating time.
