Optical connectors for printed circuit board interfaces are required for the implementation of high-density multi-fiber connection. We have developed a 16-fiber fiber physical contact (FPC) connector to meet this requirement. In the FPC connector, two arrays of fibers are aligned in micro-holes without ferrules, and contact is maintained by the pressure generated by the elasticity of the fibers. The FPC connector has to ensure the reliability to the use of bare fibers. Moreover, the FPC connector must provide a more reliable coupling mechanism and higher density connection. To meet these requirements, we employ the MU connector coupling mechanism and a shutter, and we connect 16 fibers in the housing of the duplex MU connector. We developed compact shutters that open only when they come into contact with each other. The developed 16-fiber FPC connectors had an average insertion loss of 0.06 dB and a return loss of over 45 dB. The optical performance remained stable in environmental and mechanical tests.
