Abstract:
An optical transmit-receive coupler for optically connecting optical fibers to each other, each said optical fiber having approximately the same index of refraction and being supported by an associated fiber plug, comprising:a housing having a first open end and a second open end and being adapted to receive said optical fiber plugs in the first and second open ends, respectively;a support member mounted within said housing in a longitudinally central position of said housing; anda light-permeable member supported by said support member in a position aligned with said first and second open ends of said housing such that said optical fibers are connected with each other through said light-permeable member when said optical fiber plugs supporting the respective optical fibers are inserted into said housing through said first and second open ends, respectively, said light-permeable member having a refractive index approximately equal to said refractive indexes of each of said optical fibers.
