Summary: 
Optical connectors for printed circuit board interfaces are required for the implementation of high-density multi-fiber connection. We have developed a fiber physical contact (FPC) connector to meet this requirement. The FPC connector has to ensure reliability when bare fibers are used. Moreover, the FPC connector must employ an established coupling mechanism and provide higher density connection. To meet these requirements, we developed a 16-fiber FPC connector that utilizes the MU connector coupling mechanism and a shutter. We connect the 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. Moreover, the developed FPC connector enables us to clamp the fibers to a plug without adhesive. This structure can greatly boost the production yield. We confirmed that the developed FPC connector has an easy connection operation and good optical performance, and we verified that the shutters open properly.
