There is provided an opto-electronic communication system. The opto-electronic communication system has (a) a transmitter module including an electro-optical source for converting an electrical input signal into an optical output signal, (b) a receiver module including an opto-electrical detector for converting an optical input signal into an electrical output signal, (c) a sensor for sensing a bit rate of the optical input signal, (d) an adaptation unit associated with the transmitter module for varying an operation parameter of the transmitter module, and (e) a processing unit for determining a desired operating parameter of the transmitter module based on the bit rate, and for controlling operation of the adaptation unit in order to adapt operation of the transmitter module in accordance with the desired operating parameter.

Electro-optical communication system

A method for evaluating the aging level of a component includes measuring values of the elapsed time in operation of the component (t), at least one entity (I) indicative of the aging of the component, and the temperature (T) of the component, and processing the values measured as a function of a reference temperature (T) to produce corresponding normalized reference values (t; I) representative of virtual operation of the component at said reference temperature (T). An updated prediction model for the at least one entity over time is generated from the reference values (t; I). A predicted value (I) for the at least one entity at a given time obtained by means of the prediction model is compared with an aging threshold. An aging warning signal is generated if the comparison indicates deviation of the predicted value (I) beyond an acceptable range.
