摘要
利用实验室自制的40Gbit/s光时分复用(OTDM)结构,搭建了4×10Gbit/sOTDM100km的传输系统,基于电吸收调制器和时钟提取模块组成的解复用模型,成功实现了传输后10GHz时钟分量的提取和10Gbit/s信号的无误码传输及解复用.通过实验比较了中间补偿和后补偿2种不同方式下的色散补偿效果,同时实现了色散和色散斜率的补偿,其分别引入的功率代价约为0.8、0.65dB.
A 4 × 10 Gbit/s optical time-division multiplexed （OTDM） 100 km transmission system with home-made multiplexer is implemented utilizing the clock recovery module combined with the sampling window of electrical absorption modulator （EAM）. Error-free demultiplexing is achieved experimentally. Dispersion and dispersion slope compensation are implemented simultaneously under the conditions of compensation-in-middle or compensation-in-end. And the power penalty is approximately 0. 8 dB and 0.65 dB respectively after transmission.
