Optical Links for Microwave Application
Abstract
The RADC Directorate of Communications, Communications ECCM Section, in cooperation with the RADC Photonics Laboratory, Lightwave Signal Processing Group, is in the process of replacing the existing RF cabling system of their anechoic chamber with optical links. Fiber optic links will be employed in an effort to upgrade the DCCD anechoic chamber test facility. It is expected that any electro-magnetic interference emanating from the existing microwave system can be reduced measurably by replacing the antenna coaxial cabling and its associated components with optical link systems. This effort should not only improve the DCCD test bed, but will yield valuable data about the future of optical component applications in the microwave domain. This report details the Photonics Laboratory's portion of this effort. While this report is related to this specific application, a more detailed characterization and analysis of the optical links will be carried out to provide information as to feasibility of using optical links as fiber feeds in microwave systems. We report on the performance of these fiber optic components in the area of their noise contribution, bandwidth, and dynamic range capabilities as related to the needs of a typical communications system.
