Abstract :
A novel remote node (RN) scheme based on gain saturated reflective semiconductor optical amplifier (GS-RSOA) cascaded electroabsorption transceiver (EAT) is presented for linearization and reduction of dispersion induced carrier suppression (DICS) for uplink transmission. The help of gain saturation property of RSOA, the transfer curve of EAT can be linearized and transmission performance can be robust from DICS. By using the proposed scheme, carrier to interference ratio (CIR) was enhanced by 10.7 dB at the 10 GHz frequency band and 33.4 dB gain of 5.65 GHz RF frequency was measured for 75.6 km data transmission.
