    Abstract: An optical network contains dispersion compensation modules with Fiber Bragg Gratings. A photo detector behind the Fiber Bragg Grating detects the not reflected rest of the gratings input signal and therefore the dispersion compensation modules input signal. This information is used to reduce the expenditure and to avoid errors of configuration or administration of the dispersion compensating subsystem of the optical network.

    Abstract: A received optical signal is coherently demodulated and converted into orthogonal x-polarization samples, and y-polarization samples. These samples are converted into signal x-samples and signal y-samples by an FIR butterfly filter. Correction values are calculated in an error calculating circuit of a control unit and added to filter transfer functions derived by a standard algorithm to determine corrected filter coefficients. Degenerate convergences calculating the transfer functions are avoided.

    Abstract: A Raman pumping device (10) for amplifying a data optical signal in a fiber optic transmission system, comprising first and second ports (12a, 12b) through which the data optical signal may respectively enter and exit the Raman pumping device (10), a Raman pump source (14) for generating a Raman pump signal, and at least one combiner (16) for combining the Raman pump signal with the data optical signal. The Raman pumping device (10) allows for selectively combining the Raman pump signal generated by the same Raman pump source (14), or at least parts of the same Raman pump source (14) codirectionally or counterdirectionally with the data optical signal.

    Abstract: A wavelength selective switching device comprises a plurality of input paths for receiving optical signals, a plurality of output paths for emitting the optical signals, and a switching unit for selectively directing the optical signals from the input paths to the output paths. The switching unit comprises a reflective area adapted to be concurrently illuminated by a first optical signal from a first input path among the plurality of input paths, and by a second optical signal from a second input path among the plurality of input paths, the second input path being different from the first input path, and to concurrently direct the first optical signal to a first output path among the plurality of output paths and the second optical signal to a second output path among the plurality of output paths, the second output path being different from the first output path. Said first output path and said second output path are spatially separated by said first input path and said second input path, or vice-versa.

    Abstract: A method of assigning performance indicators to objects of a network employing a computation to assign performance indicators to said objects of said network such that a sum of said performance indicators of objects along a given path in said network in relation to a first threshold value indicates whether said path fulfils a predetermined criterion, and/or indicates whether said path does not fulfil said predetermined criterion.A method of evaluating a performance of a path in a network based on the performance indicators involves the steps of calculating a sum of performance indicators for said objects along said path and evaluating a performance of said path by comparing said sum against a first threshold value.

    Abstract: A cable clamp for clamping a cable with respect to a through hole of a solid object is presented. The cable clamp includes first and second elements (102, 103) and retainer devices (105) for keeping the first and second elements with respect to each other so that the cable gets clamped between the first and second elements and the cable clamp gets locked to the edges of the through hole with the aid of first claws extending over the edges of the through hole on a first side of the solid object and with the aid of second claws capable of extending over the edges of the through hole on the second side of the solid object. The cable clamp can be inserted into the through hole when the first and second elements are tilted with respect to each other so that the first claws are nearer to each other.
