A high-density wavelength division demultiplexer (DEMUX) capable of demultiplexing eight-channel 200-GHz optically spaced signals into a 62.5-microm multimode-fiber array is reported. The wavelength range of operation is from 1549.32 to 1560.61 nm within the International Telecommunication Union grid. The measured wavelength accuracy is within 0.04 nm. The mean insertion loss of this DEMUX is 1.95 dB. Thermal analysis and temperature testing results are reported. The temperature test cycling from 20 degrees C to 60 degrees C indicates that the wavelength thermal drift is less than 0.8 pm/degrees C. Adjacent cross talk is measured to be better than -45 dB. The measured data transmission bit rate of this device is higher than 3.5 Gb/s.
据报道，一种能够将八通道200千兆赫光间隔信号解复用为62.5微米多模光纤阵列的高密度波分复用器（DEMUX）。其工作波长范围在国际电信联盟网格内为1549.32至1560.61纳米。测量的波长精度在0.04纳米以内。该解复用器的平均插入损耗为1.95分贝。报告了热分析和温度测试结果。从20摄氏度到60摄氏度的温度测试循环表明，波长热漂移小于0.8皮米/摄氏度。测量的相邻串扰优于-45分贝。该器件的测量数据传输比特率高于3.5吉比特/秒。
