What are the C-band and L band microwaves used for?

Long-wavelength band (L-band) The L-band, ranging from 1565 nm to 1625 nm, stands for the long-wavelength band (see Figure 1). It is the second primary wavelength band used for optical communication, because attenuation of optical fiber in the L-band is the second lowest after the C-band.

Frequency range in which Band L operates To round off the faculties that adorn the L Band satellite frequency, we must say that the L band operates in a range of frequencies ranging from 1,530 to 2.7 Ghz , being the one with the lowest frequency amongst satellite bands used in the market.
