OPTICAL CONNECTOR

To provide an optical connector capable of attaining speed-up of communication.SOLUTION: An optical connector 1 comprises: optical fibers 4; lenses 35a that are disposed oppositely to end faces 4a of the optical fibers 4 in an optical axis direction and receive emission light emitted from the end faces 4a; and optical filters 36 that are disposed between the end faces 4a and the lenses 35a and have through holes 36a for transmitting a part of the emission light. When an inner diameter of the through hole 36a of the optical filter 36 is represented as B, a distance from the end face 4a to the optical filter 36 in the optical axis direction is represented as L, a maximum passage light emission angle, smaller than a maximum emission angle α of the emission light, of passage light passing through the through hole 36a is represented as α', and an outer diameter of a core 41 of the optical fiber 4 is represented as 'A', B=2×L×tanα'-A and L>A/tanα'/2 are satisfied.SELECTED DRAWING: Figure 4 【課題】通信の高速化を図ることができる光コネクタを提供する。【解決手段】光コネクタ１は、光ファイバ４と、光ファイバ４の光軸方向における端面４ａと対向して配置され、かつ端面４ａから出射される出射光を受光するレンズ３５ａと、端面４ａとレンズ３５ａとの間に配置され、かつ出射光の一部を通過させる貫通孔３６ａを有する光学フィルタ３６とを備える。光学フィルタ３６の貫通孔３６ａの内径をＢ、端面４ａから光学フィルタ３６までの光軸方向における距離をＬ、出射光の最大出射角αより小さくかつ貫通孔３６ａを通過する通過光の最大通過光出射角α´、光ファイバ４のコア４１の外径をＡとすると、Ｂ＝２×Ｌ×ｔａｎα´−Ａ、Ｌ＞Ａ／ｔａｎα´／２を満たす。【選択図】図４
