Redundant Fiber-Optic Transceivers for Remote Testing

Redundant fiber-optic transceivers have been incorporated into the High Speed Data Acquisition System (HSDAS) at Stennis Space Center, where they are used to communicate data acquired by remotely located instrumentation during tests of spacecraft engines. These and similar transceivers could also prove useful in other situations in which there are requirements for acquiring data at safe distances from instrumentation located in hostile or potentially dangerous environments.
