Optical spectrum synonyms, Optical spectrum pronunciation, Optical spectrum translation, English dictionary definition of Optical spectrum. What does OSA mean? Spectrum, Optical a spectrum of electromagnetic radiation encompassing the infrared, visible, and ultraviolet regions. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 380 to 750 nanometers. The port is typically labeled “optical audio”, “TOSLINK”, “Digital Audio Out (Optical)” or something similar, but you certainly don’t need a label to identify it. In the 1300-1500nm region, the spectral widths of the LED vary from 50 to 180nm. Browse A-Z. Lexicographical Neighbors of Optical Spectrum. 2.
