FIBER OPTIC COMMUNICATIONS IN A TELEMETRY SYSTEM

Abstract

This paper discusses the conversion of an existing telemetry system to the use of fiber optic communications. The change was implemented to provide expanded capabilities of existing capital assets with a minimum of investment. The paper reviews the design constraints and options considered for a specific flight test program. The different options, such as fiber type, connector type, wavelength, bit rate, and encoding method, are compared and discussed as to their applicability, reliability, and cost effectiveness in a telemetry environment. The paper discusses the solution selected and the capabilities of the final design, as compared to the initial system.
