摘要
本文介绍了用电吸收调制器(EAM)作为下行光电探测器(PD)和上行射频调制器对光纤无线电(ROF)性能的评价。结果表明,EAM器件具有作为系统远端天线单元(RAU)收发机的潜力。带有偏置EAM的130 m ROF系统能够在激光二极管输出功率为8.7 dBm的情况下获得18 Mbps的对称WLAN 802.11a数据速率。
Adopting Electroabsorption Modulator for the WLAN 802.11a Radio over Fibre System
This paper presents the evaluation of radio over fibre (ROF) capability with electroabsorption modulator (EAM) as a downlink photodetector (PD) and uplink radio frequency (RF) modulator. The results show that the EAM device has potential to be adopted as the transceiver at the remote antenna unit (RAU) for the system. The 130 m ROF system with biased EAM is capable to obtain a symmetrical WLAN 802.11a data rate of 18 Mbps with laser diode output power of 8.7 dBm.
