  • Flexible optical connecting part
    Patent number: 7043107
    Abstract: A flexible optical connecting part having enhanced flexibility and what is more, increased degree of freedom of routing. The flexible optical connecting part includes a flexible optical board having a body and tabs provided in a manner continuous with the body. Optical connectors are provided on the tabs. Tab-forming parts forming part of the tabs are formed with cuts.
    Type: Grant

  • Optical connector module
    Patent number: 6851868
    Abstract: There is provided an optical connector module of which an optical transmission/reception wafer and an optical waveguide wafer can be registered with each other easily and accurately without misregistration. An optical transmission/reception wafer has guide pin-receiving V-grooves with a V-shaped cross-section, formed at locations preset in association with an optical transmission/reception end of an optical transmission/reception section. An optical waveguide-side connector has an optical waveguide wafer formed with guide pin-receiving V-grooves in association with the guide pin-receiving V-grooves of the optical transmission/reception wafer. Wafer registration guide pins are inserted in these guide pin-receiving V-grooves, and the optical transmission/reception wafer and the optical waveguide wafer are brought close for interconnection such that these guide pins are tightly sandwiched by the guide pin-receiving grooves.
