Abstract
A terminal element for fiber optic communication has an elongated body defining a body axis and having a first end from which an optical fiber extends along the body axis. The body has a second end with an angled surface offset at an angle from the body axis. The fiber extends partly through the length of the body, and terminates at a fiber end surface. The second portion has an optical entry surface registered with the fiber end surface such that light emitted from the fiber end surface enters the optical entry surface. At least one of the fiber end surface, angled surface and optical entry surface has a figured optical form with a non-planar shape.

A terminal element for fiber optic communication comprising:
- an elongated body defining a body axis and having a first end from which a plurality of optical fibers extend along the body axis;
- the body having a second end with an angled surface offset at an angle from the body axis;
- the fibers extending through the length of the body, and each of said fibers terminating at a fiber end surface flush with the angled surface;
- and
- the body defining a plurality of figured optical elements on the angled surface;
- wherein
- each of said optical elements is registered with a respective one of said fiber;
- and each of said optical elements is figured to concentrate light from said respective fiber in a distinct area separate from the light from adjacent fibers;
- the body having a third surface parallel to said body axis and being substantially flat, a portion of said third surface being an optical exit zone surface, said optical exit zone surface being registered with the figured optical elements, the exit zone surface being flat and coplanar with said third surface.
A terminal element for fiber optic communication, comprising:
- an elongated body defining a body axis and having a first portion supporting a plurality of optical fibers extending along the body axis;
- the body having a second portion with an angled surface offset at an angle from the body axis;
- the fibers extending partly through the length of the body, and terminating at a fiber end surface;
- the second portion having a plurality of optical entry surfaces registered with the fiber end surface of a respective one of said fibers such that light emitted from one of said fiber end surfaces enters its respective optical entry surface;
- and
- each of said optical entry surfaces having a figured optical form with a non-planar shape;
- the body having a third potion, said third portion being parallel to said body axis and being substantially flat, a part of said third portion being an optical exit zone surface associated with the figured optical elements, the optical exit zone surface being flat and coplanar with said third portion.
