Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry (2204.06093v1)

Published 21 Feb 2022 in physics.ins-det

Abstract: Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of both is substantially less than for SSMF with some dependency on coating type.
