Abstract
Abstract A connector for providing input-output couplings to optical transmission lines without interrupting the optical radiation flow. A transparent 45* prism is inserted between scrambling rods connected between ends of the transmission line. Part of the surface of the prism has mirror coatings. Auxiliary rods having input and output couplings are then bonded at right angles to the prism to provide the coupling.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
147 words
An optical coupler-connector for providing input into and output from a main optical multimode fiber optic transmission line, which comprises: first and second optically transparent scrambler arms; said scrambler arms optically bonded at one end to the ends of said main transmission line; a central element optically connected between said first and second scrambler arms; said central element including a 45* prism with mirrored faces in one half section thereof and a solid rod forming the remainder of said central element; said 45* prism positioned with its mirrored faces at a 45* angle relative to an axial line through said first and second scrambler arms of said coupler-connector; a third scrambler arm optically secured to said central element with its optical axis perpendicular to the axis through said first and second scrambler arms; and input and output auxiliary transmission lines optIcally connected with said third scrambler arm.
Claim 2
Dependent Claim
147 words
An optical coupler-connector for providing input into and output from a main optical multimode fiber optic transmission line, which comprises: first and second optically transparent scrambler arms; said scrambler arms optically bonded at one end to the ends of said main transmission line; a central element optically connected between said first and second scrambler arms; said central element including a 45* prism with mirrored faces in one half section thereof and a solid rod forming the remainder of said central element; said 45* prism positioned with its mirrored faces at a 45* angle relative to an axial line through said first and second scrambler arms of said coupler-connector; a third scrambler arm optically secured to said central element with its optical axis perpendicular to the axis through said first and second scrambler arms; and input and output auxiliary transmission lines optIcally connected with said third scrambler arm.
