Testing Fischer Fiber Optic Connectors At Cryogenic Temperatures

By Jean Baptiste Gay, Fischer Connectors

Fischer Connectors tested the performance of a Fischer Fiber Optic Series connector at 1.9 Kelvin at CERN’s cryogenic facility (SM18) under the EuCARD-2 Transnational Access program. The test objective was to measure the robustness of the connector in the cryogenic environment. The Fischer connector was lined inside the sealed cryostat with the outside environment, and temperature was slowly reduced in the cryostat, cooling the helium inside to superfluid helium phase at 1.9 K.
