Information transmission system, using direct light-modulation, optical-link and a bandwidth extended towards low frequencies and direct current

摘要

System directly modulated information transmitting light having an optical link having at its input transmitting means (1) and at its output receiving means (4, 40) responsive both to the junction temperature, sensitivity at low frequencies creating faults affecting the transmission of said frequencies. Inserting both of the transmission side that the reception side, filtering means (8, 6, 7, 9) compensating for the linear thermal effects and non-linear transmission and the linear thermal effects of the receiving means.
