Abstract: 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.

Abstract: A method for evaluating the aging level of a component includes measuring values of the elapsed time in operation of the component (tm,i), at least one entity (Im,i) indicative of the aging of the component, and the temperature (Tm,i) of the component, and processing the values measured as a function of a reference temperature (Tref) to produce corresponding normalized reference values (tref,i; Im,i) representative of virtual operation of the component at said reference temperature (Tref). An updated prediction model for the at least one entity over time is generated from the reference values (tref,i; Im,i). A predicted value (Ifit) 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 (Ifit) beyond an acceptable range.

Abstract: An opto-electronic communication system includes at least one of a transmitter module including an electro-optical source such as a laser for converting an electrical input signal (IS) into an optical output signal (OS), and a receiver module including an opto-electrical detector for converting an optical input signal (OS?) into an electrical output signal (IS?). The system also includes at least one adaptation unit configured for varying at least one operation parameter of the transmitter module and/or receiver module. A processing unit such as a microcontroller is provided for controlling operation of the one adaptation unit in order to adapt operation of the transmitter module and/or receiver module to different operation conditions such as different communication standards.

Abstract: The aging level of a component, such as a laser (24) in an optical communication system, is evaluated by performing at repeated instants of time (i) during the useful life of the component (24), the steps of: measuring values of the elapsed time in operation of the component (tm,i), at least one entity (Im,i) indicative of the aging of the component (24), and the temperature (Tm,i) of the component, processing the values measured as a function of a reference temperature (Tref) to produce corresponding normalized reference values (tref,i; Im,i) representative of virtual operation of the component at said reference temperature (Tref). Starting from the reference values (tref,i; Im,i) thus produced, an updated prediction model for said at least one entity over time is generated. A predicted value (Ifit) for said at least one entity at a given time obtained by means of the prediction model is compared with an aging threshold.

Abstract: The arrangement includes first and second patterns such as photolithographic patterns of electrically conductive indicia provided on respective first and second surfaces of the components to be positioned. The patterns are adapted for relative movement in sliding contact relationship along the positioning axis. The patterns of electrically conductive indicia define electrically conductive pads at least one of which reaches the condition of being either open or closed when the surfaces on which the patterns are provided reach a given position along the positioning axis. Sensing is preferably effected by means of an amperometer.

Abstract: The device, which has a modular structure, makes use of Bragg gratings for selecting, from a wavelength division multiplexed stream, a carrier to be inserted or extracted, and optical circulators for receiving the stream, for extracting and inserting the carriers and for sending the multiplexed stream to the output after the extraction and insertion of the carriers. The grating and the receiving-extracting circulator are located in a structural module which is replicated for all the channels to be extracted and inserted.

Abstract: The arrangement includes first (3) and second (4) patterns such as photolithographic patterns of electrically conductive indicia provided on respective first (1a) and second (2a) surfaces of the components (1, 2) to be positioned. The patterns (3, 4) are adapted for relative movement in sliding contact relationship along the positioning axis (x). The patterns of electrically conductive indicia (3, 4) define electrically conductive pads at least one of which reaches the condition of being either open or closed when the surfaces (1a, 2a) on which the patterns (3, 4) are provided reach a given position along the positioning axis (x). Sensing is preferably effected by means of an amperometer.
