What does L band mean?
long-wavelength 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.
