Title:
MULTICORE OPTICAL FIBER, OPTICAL COMBINER, AND FIBER PROPERTIES MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/176085
Kind Code:
A1
Abstract:
Provided are an MCF and the like comprising a structure for suppressing increases in connection loss even when there is axial deviation between cores that are to be optically connected. This MCF comprises a plurality of cores and a shared cladding surrounding the plurality of cores. At the wavelength 1260 nm, ten or more LP modes including the fundamental mode are guided 1 m or more.
