The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz). The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. It should not be confused with the 600–1,000 MHz range of Band V (Band Five) of the UHF frequency range. WebMar 17, 2024 · O-band was the “original” band, the first for which we learned how to build lasers and detectors. Over time, the very low chromatic dispersion has allowed use of particularly cheap laser sources, making O-band the preferred choice for short reach optical interconnects, for which the higher attenuation per km is not a problem.
