ABSTRACT:
An optical fiber coupler (10) is disclosed for interconnecting a tap cable (20) to a bus cable (30). Each cable has a portion of its sheath removed at the point of coupling to provide exposed cores (24,34). The cores are intertwined a number of times and the tension on the cables is adjusted to yield the desired loss. A cladding material fills the intertwined region, including the interstices of the cores, to provide a continuous sheath in the axial dimension.
