Abstract
A monolithic sequential coupling arrangement has two or more fused biconic couplers joined with one common optical fiber which is not spliced. The couplers are close together in a space-saving relationship exhibiting a relatively low polarization dependent loss. The non-fused fiber portions in the arrangement have each at least one adiabatic taper.
