Abstract

Received signal from weather satellite is overlaid with WDM RoF technique on 10.7Gb/s (OTU2) data stream. For extending the signal transmission distance between the antenna and the receiver, a low noise amplifier is designed by using an EP-HEMT to achieve lower noise and higher gain so that the received signal level is as low as −130dBm. The received signal is amplified by using a laser driver which is also designed by using the EP-HEMT. A low noise and linear 1550nm DFB laser is modulated by the laser driver. The converted optical signal is overlaid on a 10.7Gb/ (OTU2) data streams by using a 1310/1550nm WDM. A clear image from the weather satellite is received after 40km SMF. There was no degradation in the eye diagram and total jitter of the 10.7Gb/s data signal.
