Disclosed is a color optical link using a transparently jacketed plastic
optical fiber that optically transmits data and uses light, scattered and
emitted to the outside, for the purpose of illumination, and a method for
achieving the color optical link. The color optical link includes a first
driver that receives digital or analog signals and a coloring signal in
parallel and converts these signals into optical signals through a
plurality of light sources. These light sources emit light of different
wavelengths. A first POF coupler, connected at one end of the optical
fiber, inputs the received optical signals into the optical fiber. A
second POF coupler at the other end separates the transmitted optical
signals into a plurality of optical signals and inputs these optical
signals into a plurality of optical detectors having filters for
separating the received signals into plural signals according to
wavelength. A second driver converts the received optical signals into
electrical signals.
