The present invention relates to an optical probe system (100) comprising an optical probe (18) having an optical converter circuit (10) with an optoelectronic device (15). The optoelectronic device is arranged for converting a first radiation beam (2) from a radiation source (6) into electrical energy and for receiving first data comprised in said first radiation beam. The optical converter circuit (10) is powerable by said electric energy in the first radiation beam (2). The optoelectronic device is further arranged for emitting a second radiation beam (3) towards a photodetector (5), said emission being inducible by the incoming first radiation beam, the second radiation beam comprising second data. The invention is advantageous for obtaining an improved optical probe system capable of obtaining a higher data transmission and/or a relatively high power at the distal end of the optical probe system with relatively high efficiency and simultaneous at small size.
