摘要:
A reflective type optical signal distributor comprising, in a housing (2), a plurality of optical input/output units (3) functioning as input and output terminals for an optical signal, an optical circuit assembly (6) for reflecting and separating the optical signal, and a plurality of guide optical fibers (8) for connecting the plurality of optical signals entering any one of the plurality of optical input/output units (3) and the optical circuit assembly (6), whereby an optical input/output units (3) is substantially equally distributed to all other ones of the plurality of optical input and output units (3), the optical circuit assembly (6) comprising an optical circuit in which a plurality of independent branched optical waveguides (22) merge into a single main optical waveguide (21), a reflective surface (4) formed at an end of the main waveguide (21), and the plurality of guide optical fibers (8) being connected to the corresponding plurality of independent branched optical waveguides (22).
