Abstract

A tap for coupling light from an intermediate portion of an optical fiber core and a light element by passing light through a side of the optical fiber includes an optical coupler in contact with an outside surface of an optical fiber which is bent and disposed in a plane. A light reflector extending transverse to the plane deflects the withdrawn light towards the end surface of a light element disposed completely outside the plane. The tap may be used as a read tap to withdraw light, or as a write tap to inject light in optical fiber networks. A spring biased closure member urges the optical fiber to be maintained in bent registration with the optical coupler within the plane. A rail and channel is used to conveniently guide a tap closure member against the optical fiber. Simple tools and general craft training and knowledge may be applied to insert into and remove the optical fiber from the tap.
