摘要
A system for transmitting an optical signal over a fiber optic includes a terminal for generating the optical signal. Due to its modulation, the optical signal includes a carrier having a wavelength "λ", with an upper sideband and a lower sideband. A tuner is connected with the terminal to adjust the wavelength "λ" of the carrier of the optical signal relative to a band pass filter. The purpose here is two-fold. For one, this adjustment eliminates a sideband of the optical signal, to avoid fading, and it suppresses the carrier of the optical signal, to enhance the OMI while maintaining the linearity of the signal.
