Patent ID: 7311450

Claim:
A color optical link using a transparently jacketed plastic optical fiber, comprising: a plurality of the light sources for emitting light having different wavelengths in order to output a plurality of optical signals; a first driver for receiving digital or analog signals and a coloring signal in parallel and converting the received signals into the plurality of optical signals through a said plurality of light sources; a first POF coupler for inputting the plurality of the optical signals received from the plurality of the light sources into the transparently jacketed plastic optical fiber; the transparently jacketed plastic optical fiber having one end connected to the first POF coupler and the other end connected to a second POF coupler, said second POF coupler being provided for separating the optical signal transmitted from the transparently jacketed plastic optical fiber into a plurality of optical signals and respectively inputting the optical signals into a plurality of optical detectors, said plurality of the optical detectors respectively having filters for separating the received optical signal into a plurality of signals according to wavelengths; said first and second POF couplers are designed such that a plurality of optical fibers for transmitting the plurality of optical signals are polished and bound into an optical fiber unit so that the optical fibers are uniformly arranged along a circumference of the optical fiber unit, thus inputting and outputting the plurality of optical signals in parallel to and from the transparently jacketed plastic optical fiber; and a second driver for receiving the optical signals from the optical detectors and converting the receiving optical signals into electrical signals.
