Patent ID: 8272788

Claim:
An optical-path turning device to be interposed between first and second optical components of pin-fitting alignment system having mutually different optical paths, for an optic coupling between the optical components, the optical-path turning device comprising: a device body of a block shape made of resin comprising; a first connector portion provided with fitting pinholes facing to fitting pinholes of the first optical component, respectively, and having a connection end face to be butt-connected with a connection end face of the first optical component; a second connector portion provided with fitting pinholes facing to fitting pinholes of the second optical component, respectively, and having a connection end face to be butt-connected with a connection end face of the second optical component; and a set of optical waveguide extending from the connection end face of the first connector portion to the connection end face of the second connector portion through a flexural portion, wherein the first connector portion is provided with cutouts at both sides in a width direction thereof; the respective fitting pinholes of the first optical component are through holes passing from the connection end surface to the respective cutouts; the respective fitting pinholes of the second optical component are through holes passing over a whole length of the second optical component in a longitudinal direction thereof; and the first and second connector portions are detachable to the first and second optical components, respectively.
