FIBER OPTIC NETWORKING DEFINITION (continued): … the IR or visible beams to electrical signals and routing those signals using conventional electronic switches. The rerouted electrical signals were then converted back into IR or visible beams.In a conventional ROADM, switching is accomplished without optical-to-electrical or electrical-to-optical conversion using three operations called add, drop and cut-through. An outgoing IR or visible beam can be generated (the add operation) or an incoming beam terminated (the drop operation). A beam can also be passed through the device without modification (the cut-through operation). In combination, … Fiber Optic Networking definition sponsored by SearchTelecom.com, powered by WhatIs.com an online computer dictionary
