ABSTRACT OF THE DISCLOSURE A centering device, for holding an optical fiber along an axis, includes three sections of fiber receiving means, and a receiving member. The receiving member has a cylindrical recess, concentric with the axis, for hold- ing the sections in assembly, The sections are substan- tially identical, each having a uniform cross-sectional configuration at right angles along a major portion of its length forming a boundary of fixed perimeter. One portion of the boundary of one section contacts another section. Another portion of the boundary contacts a different sec- tion. A third portion contiguous to the first two portions is adapted to engage an optical fiber along its length. A fourth portion contiguous to the first two, but not to the third, engages the cylindrical wall defined by the concentric recess of the receiving member. The recess ter- minates with a planar wall perpendicular to the axis. It can have an axially oriented depression. The fourth por- tion of the boundary engages differing amounts of a cylin- drical wall depending upon the shape of the fourth portion. The sections include elastomeric material of sufficient resilience for a passageway defined by the third portions of assembled sections to expandably receive an optical fiber dimensioned larger than the passageway. The passage- way can have a substantially triangular cross-section for receiving a fiber having a substantially circular cross- section. It can flare outwardly from a position interior the fiber receiving means to respective ends thereof. Passageway flaring can have a triangular, a hexagonal, or a circular configuration. The device can have a fiber re- ceiving means with a polygonal shaped external surface. The receiving member can be transparent. The fiber re- ceiving means can be held within the recess of the member by a force fit. The radius of the three sections, when assembled but prior to insertion into the recess, is greater than the radius of the recess.
