<p>The system has computers (A, B) exchanging information through an optical fiber (3), where the safety level of the computer (A) is lower than that of the computer (B). The optical fiber has a passive optical isolator (4) with constant or adjustable attenuation level. The isolator is adapted to transmit in a unidirectional manner, the information from the computer (A) to the computer (B).</p> |
