RECOMMENDATION ITU-R V.431-8 Nomenclature of the frequency and wavelength bands used in telecommunications (1953-1956-1959-1963-1966-1974-1978-1982-1986-1993-2000-2015) Scope This text recommends the use of the hertz (Hz) as the unit of frequency, and the nomenclature to be used for the description of frequency and wavelength bands.
This text recommends the use of the hertz (Hz) as the unit of frequency, and the nomenclature to be used for the description of frequency and wavelength bands. It also provides extended information on nomenclature used in some applications.
Recommendation ITU-T G.694.1 provides a frequency grid for dense wavelength division multiplexing (DWDM) applications. The frequency grid, anchored to 193.1 THz, supports a variety of channel spacings ranging from 12.5 GHz to 100 GHz and wider.
This is an overview of the standard ITU-T G.694.1 100GHzGrid DWDM wavelengths that are currently supported by ghip systems DWDM products. Products that support different DWDM channels are available on request.
Section I – Frequency and wavelength bands. 2.1 The radio spectrum shall be subdivided into nine frequency bands, which shall be designated by progressive whole numbers in accordance with the following table. As the unit of frequency is the hertz (Hz), frequencies shall be expressed: in kilohertz (kHz), up to and including 3 000 kHz;
8 Αυγ 2022 · Understanding the relationship between frequency f [Hz] and wavelength λ [m] is fundamental for a professional EMC design engineer. This chapter introduces the term wavelength λ and explains how the wavelength of an electromagnetic wave depends on the cable insulation or PCB material.
The ITU Radio Frequency to Wavelength conversion tool allows you to enter a frequency from 8.3kHz to 11.2GHz and calculate the Wavelength. It will also show you what the primary ITU allocation is for that frequency by selecting your desired region in the field below.
