Measurement Method for Inter-core Crosstalk and Intrinsic Attenuation in a Weakly Coupled MCF by OTDR Technique

This study proposes a novel method for inter-core crosstalk (XT) using a standard optical time-domain reflectometer (OTDR) technique. This method can evaluate intrinsic attenuation independent of the XT. XT and attenuation values measured by OTDR are verified by comparing them with those measured by conventional methods.
