Upgrading microwave telemetry data communications with an analog lightwave system

Abstract

The author describes the work performed in replacing four microwave telemetry data communications systems with one single analog fiber-optics system at Edwards Air Force Base. The fiber-optic system used was initially designed for use in a television video system. Therefore, the author was faced with the problem of determining a method of aligning the fiber-optic system to meet the required needs of the transmission system. The objectives were met by utilizing several well-known methods of AM and FM measurement techniques not yet described in the implementation of fiber-optic communications systems. After alignment, the system transmitted the already developed basebands as well as the original microwave equipment.<>
