Abstract :
In this study, the hybrid amplifier (HA) is designed to enhance the signal power and compensate the fiber dispersion over a wide wavelength range. The uplink signal is remodulated by reusing downlink signal can transmit over 103-km SMF. In our proposed approach, the power budget and sensitivity will be improved.
