Coupler for optical fibres.

摘要

@ A non-invasive optical coupling device comprises means to hold an optical fibre while bending it with a radius of curvature sufficiently small so cause light to leak through the cladding, and means to hold a tap fibre in a predetermined position to receive at least a portion of the light leaking from the main fibre. This device enables light sources, sensors and various other optical communications devices to be connected via tap fibres to ring main fibres and data buses, without degradation of the fibres to which the tap fibres are connected.
