Fiber Optic Flight Experiment (FOFE)

Problem: This pathfinder will serve as a pathfinder for installation and performance of fiber optics in the Shuttle environment.

  • Evaluates Aerospace Standard 1773 Serial Data Bus
  • Analyzes the fiber optic system for susceptibility
  • Verifies the viability of optical-to-electrical signal conversions
Solution: Reduce PLB reconfiguration time in the OPF by providing a standard interface for data telemetry.
Initial Operation Date: Project started 7/8/97 and will fly on STS-95.
A report validating the performance of fiber optics and lessons learned from the experiment will be presented to the SSUPRCB in 1/99.
Upgrade Phase II
Technology Goal: While fiber optic communication systems are not uncommon on the ground, they are still new to the space industry.

Fiber optics can carry more data, the rate is increased 20 times over the conventional MIL 1553 copper system, not to mention the potential weight savings.

Once performance is validated in the Space Shuttle environment, standardization of telemetry interfaces located throughout the PLB will reduce Shuttle reconfiguration time.

Goals Supported: 3) Improve Supportability
4) Reduce Cost
