ABSTRACT A fiber optic coupling device and method of constructing such a device A fiber optic coupler for coupling 2n inputs and one output, n being an integer, comprising: two halves of a solid part formed with 2n-1 identical convex grooves parallel to a midplane and to a fractioning plane along which the part was separated into two halves. A plurality of optical fiber lengths are located each in one of the grooves, the halves and fibers are cut along a plane transverse to the midplane and fractioning plane at a depth selected for eliminating half of the cross-section of the fibers in the midplane. An auxiliary part formed with 2n-1 grooves having the same distribution as the 2n-1 grooves in the halves is retained in abutment against the halves, end portions of the fiber lengths being located in the grooves for optical coupling each with the end surfaces of two lengths, whereby 2n-1 elementary 2-to-1 elementary couplings are achieved.
