…condition in a fiber optic link where operation is limited by the power of the received signal, rather than by bandwidth or by distortion. (2) The decrease in magnitude of power of a signal in transmission between points. A term used for expressing the total losses on an optical fiber consisting of the…

…marketing for Ciena, provides some insight. Current optical transmission systems rely on fixed grid filtering to carve the available bandwidth into a number of channels that can be used to carry traffic. The filtering can be achieved using passive filters, active configurable MUX/DeMUX elements (e.g. Wavelength…
