A ferrule includes: a tip surface; an opening portion provided on a side opposite to the tip surface in a first direction intersecting the tip surface; a plurality of fiber grooves extending along the first direction and arranged along a second direction intersecting the first direction between the tip surface and the opening portion, the plurality of fiber grooves being capable of respectively supporting a plurality of optical fibers; and a plurality of lenses respectively disposed on extension lines of the plurality of fiber grooves. The fiber groove has a first fiber groove portion for positioning the optical fiber with respect to the lens and a second fiber groove portion for introducing the optical fiber into the first fiber groove portion. The first fiber groove portion is disposed closer to the lens than the second fiber groove portion in the first direction.

Ferrule and optical connector

An optical connector ferrule according to an embodiment includes an MT ferrule, and a spacer mounted on an optical end surface of the MT ferrule and having a guide hole into which a guide pin is inserted. The spacer has a contact surface that contacting the counterpart connector and a recess surrounded by the contact surface. The spacer includes a lens part exposed on a bottom surface of the recess and optically coupled to the optical end surface of the MT ferrule and a base part that retains the lens part by surrounding the lens part. The material of the lens part and the material of the base part are different from each other, and the difference between the linear expansion coefficient of the base part and the linear expansion coefficient of the MT ferrule is 0.5&#xd7;10/&#xb0; C. or less.

Optical connector ferrule and optical connector

A cable with connectors includes a plurality of electric wires arranged in parallel, and a first connector and a second connector provided at each end of the electric wires. The first connector includes a first substrate accommodated therein and a connector plug connected to the first substrate. The second connector includes a second substrate accommodated therein and a connector plug connected to the second substrate. The first substrate and the second substrate have a plurality of first contact points arranged at one end-side thereof and to be connected with the electric wires, respectively. The plurality of first contact points is arranged so that am arrangement order of the plurality of first contact points provided on the first substrate and an arrangement order of the plurality of first contact points provided on the second substrate are mirror-symmetric with the electric wires being interposed therebetween.
