A system and method for providing chirped light for an optical network. The system includes a light source configured to provide a light. The system additionally includes a driving signal source configured to provide a first driving signal. The system also includes an amplifier configured to receive the first driving signal, amplify the first driving signal, and provide a second driving signal at a predetermined amplification level, the second driving signal being the amplified first signal. Additionally, the system includes a splitter configured to receive the second driving signal and split the second driving signal into a third driving signal and a fourth driving signal. The system also includes a first attenuator configured to receive the third driving signal, attenuate the third driving signal at a first attenuation level, and provide a fifth driving signal, the fifth driving signal being the third driving signal attenuated by the first attenuator.
