Abstract

Elevator with an all optical control apparatus (10) comprising a control unit (11) with a light source (16), a photodetector (15), an optical feeding fiber (13), and an optical feedback fiber (14). The light source (16) is coupled to the optical feeding fiber (13) and the optical feedback fiber (14) is coupled to the photodetector (15). The all optical control apparatus (10) further comprises a member (12) that can be manually actuated. The member (12) comprises a fiber input (12.1) and a fiber output (12.2), said fiber input (12.1) being optically coupled to said optical feeding fiber (13) and said fiber output (12.2) being optically coupled to said optical feedback fiber (14). The member (12), when actuated, influences a light path (12.3) between said fiber input (12.1) and said fiber output (12.2) in a manner that is detectable at the photodetector (15).
