For example at 5 GHz, the transmitted power might be one megawatt and the attenuation only 4 dB/100 m. Optical ﬁbers operate at optical and infrared frequencies, allowing a very wide band-width. black slate wall oven

The numbering of the modes is standardized. The dimension w is chosen as w a, and the first index m gives the variation of the field along a. The TE 10 mode then has the lowest cutoff frequency and is called the dominant mode.
