물리적 접촉(PC) 광 커넥터는 페룰 끝면의 미세한 변위로 인한 온도 변동 중에도 광섬유와의 접촉을 유지하여 장기적인 안정성을 실현합니다. MCF(Multicore Fiber) 커넥터의 경우 MCF에는 중앙 이외의 코어가 있기 때문에 안정적인 PC 연결 조건을 새로 조사해야 합니다. 이 연구에서는 유한요소법(FEM)을 사용하여 연결된 페룰 끝면의 미세한 변위를 조사했습니다. 결과적으로 정점 오프셋이 있는 MCF 커넥터를 사용함으로써 모든 코어가 접촉하는 허용 파이버 언더컷이 단일 모드 파이버(SMF) 커넥터보다 약간 작다는 것을 발견했습니다. 따라서 우리는 MCF 커넥터의 허용 광섬유 언더컷을 결정하기 위한 새로운 방정식을 제안합니다. 또한 허용되는 섬유 언더컷을 갖는 MCF 커넥터를 제작하고 복합 온도/습도 순환 테스트를 통해 신뢰성을 확인했습니다.

Abstract: Physical contact (PC) optical connectors realize long-term stability by maintaining contact with the optical fiber even during temperature fluctuations caused by the microscopic displacement of the ferrule endface. With multicore fiber (MCF) connectors, stable PC connection conditions need to be newly investigated because MCFs have cores other than at the center. In this work, we investigated the microscopic displacement of connected ferrule endfaces using the finite element method (FEM). As a result, by using MCF connectors with an apex offset, we found that the allowable fiber undercut where all the cores make contact is slightly smaller than that of single-mode fiber (SMF) connectors. Therefore, we propose a new equation for determining the allowable fiber undercut of MCF connectors. We also fabricated MCF connectors with an allowable fiber undercut and confirmed their reliability using the composite temperature/humidity cyclic test.
