ABSTRACT:
A power controlling network element for a communication system includes a detector for measuring radiation power present in components of radiation; element parts, for example a channel control unit (CCU), transponders and other modules, for at least one of: (i) transmitting to the detector at least some components of input radiation received at the elements parts from the system; and (ii) generating one or more components of radiation and emitting the one or more components to the detector; and a field programmable gate array (FPGA) for receiving data from the detector indicative of radiation power in the components of radiation received at the detector, and for controlling radiation power emitted from or transmitted through the aforementioned element parts so that the components of radiation received at the detector are regulated in power to within predetermined power limits. Such an element is by virtue of the detector and the FPGA capable of providing accurately controlled radiation components which are not subject to overshoot or unacceptable drift.
