摘要： A multi-wavelength optical telecommunication method comprising the steps of generating at least one optical transmission signal in a predetermined wavelength band, transmitting said optical transmission signal through an optical fibre to a receiving station, receiving the optical transmission signal through a passband filter and filtering said signal to let said transmission signal alone pass, in which the wavelength band is scanned in order to identify in said band a recognizable portion of the optical spectrum being received, thus determining, based on the operating conditions corresponding to said recognizable spectrum portion, a search range of said transmission signal within which the transmission signal is searched out and recognized based on its spectral profile.

摘要： A digital optical telecommunication method comprising the steps of: generating a digital modulated optical signal in an optical transmitting station, which signal corresponds to a first electric input signal carrying a piece of information; feeding the modulated optical signal to an optical-fibre line; receiving the modulated optical signal transmitted from the optical-fibre line at an optical receiving station, converting it to an electric form and thereat generating a second digital electric signal; wherein the modulated optical signal is coded in a sequence of elementary information units at a first frequency and wherein the step of generating a second digital electric signal comprises detecting in said converted signal, an electric signal having a second frequency higher than the first frequency and recognizing in said detected signal, the phase of an electric signal at the first frequency by comparing a received sequence of elementary information units with at least one reference sequence and verifying their correspondence to a predetermined condition.

摘要： The present invention relates to the technical field of control and interfacing devices for optical fiber lines and more particularly to an adapter (6, 8, 11, 13) for amplified optical lines. Said adapter comprises an optical-to-electric converter module (18) and an adjustment module for a laser (22) different from that for the line apparatus (2), on the transmitting side (3), both modules being optically connected both at the input and at the output to the respective apparatuses (2, 15) of the line transmission (3, 17) and reception (16, 4), the corresponding optical line amplifiers (7, 12, 14, 9) being interposed therebetween; the first converter module on the transmitting side exhibits an input consisting of a photodetector (18) for carrying out the optical-to-electric conversion of the incoming signal, connected to an electrical amplifier (19) for the automatic control of the voltage level, designed to control the variations of the optical input signal, which amplifier generates at the output an electrical signal which enters the adjustment module (20) consisting of a piloting circuit for a laser (22) different from the line one, allowing the selection of the wavelength of the same and determining at the output therefrom an optical signal adjusted in accordance with the parametric requirements of the optical line amplifier to which the adapter (6) is connected, as well as controlled according to the temperature variations in time of the laser wavelength; the piloting circuit (20) exhibits at the input thereof an analog circuitry (21) for the connection with the optical service channels; on the contrary, on the receiving side the converter module, still connected to the adjustment module, although clear of control circuits for the laser wavelength depending upon temperature, exhibits the photodetector (24) coupled in alternating current through a condenser (20) to the electrical automatic voltage livel-controlling amplifier (26) connected in a circuit to the adjustment module (27) and also exhibits a second coupling (29) in alternating current, on a different circuit branch, to the connection circuitry (32) for the optical service channels through an electrical amplifier (31) ahead of which a low-frequency filter (30) is provided; in this way the adapter for optical lines appears as an optical coupling adapter both at the input and at the output and is independent of the optical line parameters, but it enables a universal connection between any type of optical transmitting-receiving apparatus and any optical line amplifier.
