Multifiber optical connector
A multifiber optical connector is provided comprising: a ferrule including a junction-end-face and a plurality of optical-fiber-insertion holes which open in the junction-end-face; openings of the optical-fiber-insertion holes arranged on the junction-end-face in a line or row or in plural parallel lines or rows; and optical fibers received in the optical-fiber-insertion holes such that they protrude from the junction-end-face. The lengths of optical fibers disposed on both side portions of the junction-end-face are greater than the lengths of optical fibers disposed on a central portion of the junction-end-face.
1. A multifiber optical connector, comprising:
a ferrule comprising a junction-end-face and a plurality of optical-fiber-insertion holes which open in the junction-end-face;
openings of the optical-fiber-insertion holes arranged on the junction-end-face; and
optical fibers which are received and fixed in the optical-fiber-insertion holes and then polished such that, on a reference plane “P” which intersects orthogonally a central axis “C” of the ferrule, which is disposed at a front side, in the connecting direction, of ends of the optical fibers, and by which positions of tips of the optical fibers are calculated and determined, a position of one of the tips of the optical fibers disposed on each side of side portions of the junction-end-face is closer to the reference plane “P” than a position of one of the tips of the optical fibers disposed on a central portion of the junction-end-face.
2. The multifiber optical connector according to claim 1 , wherein said openings of the optical fiber insertion holes are arranged in at least one line or in plural parallel lines.
3. The multifiber optical connector as recited in claim 1 , wherein an optical fiber which is disposed at an outer-most end side of said junction-end-face has a tip that is closest to the reference plane P among those of the remaining optical fibers.
4. The multifiber optical connector as recited in claim 1 , wherein a first optical fiber of an outermost fiber protrudes a length H s from the junction-end-face, a second optical fiber adjacent to the first optical fiber protrudes a length H t from the junction end-face, and a third optical fiber adjacent to the second optical fiber protrudes a length H c , such that the following relationship is satisfied,
H s >H t >H c .
