Abstract

An advanced low-reflection PC (physical contact) optical connector with an average return loss of 46 dB has been realized while maintaining a reliability as high as that of conventional PC optical connectors. The high return loss and reliability of the APC have been achieved by suppressing damaged layer generation and by reducing fiber withdrawal from the ferrule endface. Slight variations in the damaged layer significantly affect the return loss and distribution of the APC connector, because the refractive index of the layer is very close to that of silica fiber core.<>
