Referring to FIGS. 3-4, the optical connector 1 further includes a row of third lenses 13 and a row of fourth lenses 14 set on the bottom surface 102. The third lenses 13 matches with the first lenses 11 one by one. The fourth lenses 14 matches with the second lenses 12 one by one. When the optical connector 1 is assembled with the fibers 2, the pair of posts 1031 of the resin 10 being assembled to the pair of holes 41 of the seat 4, thus to make the fibers 2 contact with the resin body 10 to reduce the wastage of the light sent by the fibers 2.
FIG. 5 is another embodiment of the optical connector 1. The difference is the first lenses 11′ and the second lenses 12′ are set on one same slant surface 106′, the fibers 2′ are set in two rows corresponding to the first lenses 11′ and the second lenses 12′.
