FIBER RADIO SYSTEM WITH INTEGRATED RADIO FREQUENCY FILTER FUNCTIONALITY IN THE PHOTONIC DOMAIN.

摘要

The present invention generally concerns a system for transmitting and receiving information partly wirelessly and partly through optical fiber, and is in particular applicable to the field of telecommunications and more specifically in the construction and deployment of networks. of mobile telephony of second (2G, GSM), third (3G, UMTS) and later generations (B3G), supported by radio systems on fiber optics, allowing bandpass filtering of radio channels received directly in the optical domain, and the development of simpler and cheaper antenna repeaters and BTS, which facilitates their deployment. For this purpose, the proposed system incorporates an integrated radio frequency filtering functionality in the photonic domain that allows the implementation of radio frequency bandpass filtering functions, necessary in a radio-fiber system for mobile communications, using photonic techniques taking advantage of electro-optical devices which must necessarily be used in the radio on fiber system.
