Optical signal distributors

A reflective type optical signal distributor having a housing comprising:

• a plurality of optical input/output units functioning as input and output terminals for an optical signal;
• an optical circuit assembly for reflecting and branching said optical signal, said optical circuit assembly comprising an optical circuit in which a plurality of independent branched optical waveguides merge into a single main optical waveguide;
• a plurality of guide optical fibers for connecting said plurality of optical input/output units and said optical circuit assembly, whereby said optical signal entering any one of said plurality of optical input/output units is distributed substantially equally to all other ones of said plurality of optical input/output units;
• and
• a reflective surface formed at an end of said main optical waveguide;
• wherein said plurality of guide optical fibers are pitched and are connected to said corresponding plurality of independent branched optical waveguides, said branched optical waveguides being pitched to match the pitch of the guide optical fibers;
• and
• wherein said plurality of independent branched optical waveguides are (N+2n) in number, where n is a natural integer, N is the number of said (N+2n) branched optical waveguides excluding n branched optical waveguides at each of both edges of said optical circuit and said N branched optical waveguides are connected to said respective guide optical fibers.
