摘　　要：针对100G光传送网(OTN)设备前向纠错编码(FEC)技术标准不统一、线路侧接口互联互通困难的问题,首先介绍了针对单一厂家设备的100G互通技术原理和缺陷,然后提出一种兼容不同厂家100G OTN设备线路侧相干接口的设备技术。在模拟相干光(ACO)功能单元和数字信号处理(DSP)芯片之间引入模/数、数/模及数据预处理模块完成高速模/数、数/模转换功能,通过数据预处理功能分析出信号的厂家类别信息,进行后端DSP芯片的选择切换。实验结果表明该设备方案能够兼容不同厂家的100G OTN设备。In view of the problems of nonuniformity of forward error correction coding(FEC)technical standards for 100G optical transmission network(OTN)equipment and difficulties in interconnection of line side interfaces,this paper first introduces the principle and defects of 100G interconnection technology for single manufacturer's equipment,and then proposes a device technology compatible with line side coherent interfaces of several manufacturers'100G OTN equipment.The module of analog/digital,digital/analog and data pre-processing is introduced between the analog coherent optical(ACO)functional unit and the digital signal processing(DSP)chip to complete the high-speed analog/digital,digital/analog conversion function.Through the data pre-processing function,the manufacturer's category information of the signal is analyzed and the back-end DSP chip is selected and switched.The experimental results show that the equipment scheme can be compatible with 100G OTN equipment of several manufacturers..
