While the fibers they tested were cut into centimeter lengths, Komatsu said there’s no reason devices can’t make use of the excellent nanotube fibers from the Pasquali lab that are spooled in continuous measurements. “No matter where you measure them, they have the same very high electrical conductivity,” she said. “The piece I measured was small only because my setup isn’t capable of measuring 50 meters of fiber.”

Monitoring of JUICE Optical Fibers During Thermal Cycles Keeping the Optical Connectors at Different Stable Cryogenic Temperatures in 3-Chambers Setup Two types of multimode fibers (50µm and 400µm) will be used for the scalar sensor of the JUICE (Jupiter Icy Moon Explorer program) magnetometer. This optical sensor will be placed at the end of a boom. These multimode fibers will transmit modulated laser light through the sensor, the light source, and the detector electronics being located within the spaceship.

Optical fibers are delicate elements that can break easily, and their repair is not as simple as an electric wire. The optical fibers suffer great stress in the outdoor installations due to weather conditions and the installation itself.
