Multiple methods and systems for connecting or tapping into fiber optics
First Claim
1. An optical cable for N fibers to enhance selectively coupling to individual fiber n-groups from the cable, where n<
- N, comprising;
a first core conducting N−
n of the fibers;
a second core parallel to the first core, the second core at any point conducting n of the N fibers as a first n-group, the second core physically distinguishable from the first core; and
crossover regions at regular intervals along the cable having openings between the cores wherein fiber n-groups may switch between the first core and the second core;
characterized in that at each crossover region proceeding in one direction, a n-group of fibers in the second core crosses over into the first core, and a different n-group of fibers crosses over from the first core to the second core.

Abstract
An apparatus for interfacing optical signals to an optical fiber has a layered interface element with a first electrically conductive layer defining a first surface, a photoactive material layer in intimate contact with the first layer on a second surface opposite the first surface, a second electrically conductive layer in intimate contact with the photoactive material layer, confining the photoactive material layer between the first and second electrically conductive layers, and a third surface angularly disposed to the first surface and intersecting the photoactive material layer; and a pressure element having a contact surface translatable toward the first surface of the interface element, to urge an optical fiber positioned across the interface element into the first surface, and by local deformation of the optical fiber also into the third surface, creating thereby an intimate contact region between an edge of the photoactive layer intersecting the third surface and the optical fiber. Indentions may be provided in a fiber to facilitate engagement of elements.
