Abstract
An extended length side emitting cable is disclosed. The cable includes transmitting and side emitting fibers. As light proceeds along the side emitting fibers, it decreases in intensity and in color quality. The transmitting fibers are coupled into the side emitting fibers to refresh the light. In this manner the cable maintains increased uniformity of color and intensity along its length.
Claims15
A hybrid optical fiber cable, comprising:
- a first side-emitting illumination optical fiber;
- a second side-emitting illumination optical fiber, a first end thereof displaced longitudinally from a first end of the first side-emitting illumination optical fiber by a distance such that the optical fiber cable retains sufficient chromaticity to obtain a predetermined lighting effect;
- and
- a first low attenuation optical fiber, optically coupled to the first end of the second side-emitting illumination optical fiber.

An illumination device, comprising:
- a first side-emitting illumination optical fiber having a first end optically coupled to a light source;
- a second side-emitting illumination optical fiber, a first end thereof displaced longitudinally from a second end of the first side-emitting illumination optical fiber by a distance such tat the illumination device retains sufficient chromaticity to obtain a predetermined lighting effect;
- and
- a low attenuation optical fiber, a first end thereof optically coupled to the light source, a second end thereof optically coupled to the first end of the second side-emitting illumination optical fiber.

A hybrid optical fiber cable, comprising:
- a first side-emitting illumination optical fiber;
- a second side-emitting illumination optical fiber, a first end thereof displaced longitudinally from a second end of the first side-emitting illumination optical fiber such that the optical fiber cable retains at least one of uniform intensity and uniform chromaticity to obtain a predetermined lighting effect;
- and
- a low attenuation optical fiber optically coupled to the first end of the second side-emitting illumination optical fiber.
