INFORMATION TRANSMISSION SYSTEM, USING DIRECT LIGHT-MODULATION, OPTICAL-LINK AND A BANDWIDTH EXTENDED TOWARDS LOW FREQUENCIES AND DIRECT CURRENT

摘要

The invention provides a direct-light modulation information transmission system comprising an optical connection having at its input emission means and at its output reception means both sensitive to the junction temperature, this sensitivity creating at low frequencies defects affecting the transmission of said frequencies. Filtering means are provided, both at the emission side and at the reception side, for compensating for the linear and nonlinear thermal effects of the emission means and the linear thermal effects of the reception means.
