Abstract
Abstract An optical connector to provide input-output coupling to an optical transsion line without interrupting completely the flow of optical radiation. An optically transparent dielectric block is inserted between portions of a fiber bundle transmission line. The block has one flat side along its length which is bonded to a second material having at least one flat side along its length cooperating with the flat side of the block. The input-output bundles are attached to the second material which has the same index of refraction as the first block.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
An optical connector for connecting two sections of a main fiber optic bundle transmission line together and for coupling radiation into and out of the main transmission line; which comprises: a main optical transmission dielectric rod having ends with a cross sectional area equal to said main transmission lines; said dielectric rod including at least one side with a flat surface along a portion of the length thereof; an auxiliary dielectric rod having the same index of refraction as said main dielectric rod; said auxiliary dielectric rod including a flat side surface and joined with said main dielectric rod along its flat surface in optical alignment therewith; whereby said main dielectric rod may be optically connected to said main radiation transmission line and said auxiliary rod may be connected with auxiliary fiber optic bundles.
Claim 2
Dependent Claim
134 words
An optical connector for connecting two sections of a main fiber optic bundle transmission line together and for coupling radiation into and out of the main transmission line; which comprises: a main optical transmission dielectric rod having ends with a cross sectional area equal to said main transmission lines; said dielectric rod including at least one side with a flat surface along a portion of the length thereof; an auxiliary dielectric rod having the same index of refraction as said main dielectric rod; said auxiliary dielectric rod including a flat side surface and joined with said main dielectric rod along its flat surface in optical alignment therewith; whereby said main dielectric rod may be optically connected to said main radiation transmission line and said auxiliary rod may be connected with auxiliary fiber optic bundles.
Claim 3
Dependent Claim
25 words
An optical connector as claimed in claim 1, in which said connector includes more than one auxiliary dielectric rod secured onto said main dielectric rod.
Claim 4
Dependent Claim
