Abstract: Optical fiber-based wireless systems and related components and methods are disclosed. The systems support radio frequency (RF) communications with clients over optical fiber, including Radio-over-Fiber (RoF) communications. The systems may be provided as part of an indoor distributed antenna system (IDAS) to provide wireless communication services to clients inside a building or other facility. The communications can be distributed between a head end unit (HEU) that receives carrier signals from one or more service or carrier providers and converts the signals to RoF signals for distribution over optical fibers to end points, which may be remote antenna units (RAUs). A microprocessor-based control system or systems may also be employed.

Abstract: A synthesized digital filter and method for synthesizing the digital filter are described herein. In one embodiment of the present invention, the digital filter is made using analog RF components. In another embodiment of the present invention, the digital filter is made using optical components which enables an optical signal to be manipulated in an optical domain without needing to convert the optical signal into an electrical domain.

Abstract: A controller for an optical amplifier and a method for controlling an optical amplifier are disclosed. The illustrative method includes inputting a set-point to a controller; receiving a portion of an input signal; receiving a portion of an output signal from a first amplifier stage; receiving a portion of an output signal from an attenuation stage; receiving a portion of an output signal from a second amplifier stage and adjusting the first amplifier stage, the second amplifier stage and the attenuation stage based on the received portions to substantially maintain the set-point.
