We describe a physical-contact (PC) multicore fiber (MCF) connector with good optical characteristics. To achieve stable connection, we clarify the relationship between connector-end deformation and compression force spherical polished ferrule end structures using finite element analysis actual measurements. On basis of obtained relationship, demonstrate design approach that shows condition all cores simplex connector. In addition, criteria for low-loss connection by employing rotational angle alignment structure, devise an SC-type MCF high accuracy. Based on our designs PC provides sufficiently return loss exceeding 50dB low below 0.2dB 7-core single-mode MCF.
