FIBRO-OPTICAL CONNECTOR Russian patent published in 2010 - IPC G02B6/26 G02B5/28 

FIELD: physics.

SUBSTANCE: fibro-optical connector comprises first and second half-couplings to receive first and second sections of optical fiber. First and second pairs of step-down optical multilayer transformers are arranged on end faces of said sections. Air gap is arranged between outer layers of said first and second pairs of said transformers. Layers of first and second pairs of aforesaid transformers are made from materials with differing indices of reflection and are counted from outer layers of aforesaid transformers in direction of the end faces of connected sections of optical fiber. Thickness of every layer makes one fourth of average signal wave λ₀ transmitted over optical fiber, while the number of layers is selected subject to conditions covered by invention claim.

EFFECT: reduced power loss, expanded performances.
