资料介绍
目前，商用化的100G相干系统已经逐渐进入了部署阶段， 100G相干光系统的研发、测试越来越要求标准化以及高效率，标准的参考相干发射机和接收机作为理想的参考系统，用于测量、检定待测的接收机（或ICR）和发射机；而对于SuperChannel方式的400G或更高数据率的传输系统，目前没有专用、系统级的解决方案，大多都还是在实验室内用零散、繁多的器件、仪器搭建的复杂测试平台。
Tektronix是目前业内唯一一家覆盖了标准的相干光发射机、接收机以及校准系统的测试测量供应商，搭建简捷，系统化的测试架构为从事100G或下一代Superchannel客户，包括科研单位、研究机构、系统研发以及检测单位等等，提供稳定、高效、精确的全方位解决方案。
