Pertaining to or utilizing visible or near-visible light; the extreme limits of the optical spectrum are about 100 nanometers (0.1 micrometer or 3 × 1015 hertz) in the far ultraviolet and 30,000 nanometers (30 micrometers or 1013 hertz) in the far infrared.

Traditionally, high bandwidth signals (40 Gb/s) could only be transmitted over approximately six kilometers of standard optical fibers without optical devices to compensate for the fibers' inherent limits, such as the chromatic dispersion which results in the separation of the different optical frequencies of the signal.
