ISS Lessons Learned: Implementing of Fiber Optic Cabling in Spacecraft

KSC accepted fiber that was sub par because we did not have a process to properly inspect and verify the quality of work from the manufacturer. The ISS engineers established an inspection system for fiber to combat these issues. Optical fiber transmission uses wavelengths which are above the visible light spectrum, and thus undetectable to the unaided eye. Typical optical transmission wavelengths are 850 nanometers (nm), 1310 nm, and 1550 nm. These wavelengths were chosen because they best match the transmission properties of available light sources with the transmission qualities of optical fiber. The Boeing document MDP 0795 was developed to document the process for properly performing fiber optic inspections.
