摘要
搭建了直接检测OFDM光背靠背系统和中心注入的多模光纤系统实验平台。分析了电吸收调制激光器(EML)偏置电压对光OFDM系统性能的影响,并找出系统最佳EML的偏置电压。在OFDM系统误码率小于10^(-3)的条件下,对光背靠背和接入多模光纤两种场景,采用比特加载方法使系统传输容量最大化。
This paper describes the experimental platform of OFDM optical back-to-back system and multi- mode fiber system with center launching. It analyzes the bias voltage of EML modulator which affects the performance of optical OFDM system, and finds out the best bias voltage in such system. OFDM system transmission capacity is maximized by adaptive subcarrier bit loading method for back-to-back and mul- ti-mode fiber scenario under the condition of BER less than 10^-3.
