Abstract
(EN)
The present invention relates to a passive optical switch. The passive optical switch according to the present invention comprises: a lens array plate (120) in which fitting holes (121) are arranged in a columnar shape; a stopping plate (140) which is disposed in parallel with the lens array plate (120) and has a plurality of stopping grooves (141) formed thereon; a plurality of reception lenses (L2) which are fixed to the fitting holes (121); a transmission lens (L1) which is aligned with any one of the plurality of reception lenses (L2); a rotation shaft (130) which passes through the lens array plate (120) and the stopping plate (140); a lens rotation arm (110) which rotates about the rotation shaft (130) and has a fixing hole (121) in which the transmission lens (L1) is disposed; and a stopping arm (150) which rotates about the rotation shaft (130) and in which a stopping ball (163), which is caught in any one of the plurality of stopping grooves (141), is disposed such that the transmission lens (L1) is aligned parallel to the reception lens (L2).
