除了能改善器件性能使之满足高比特率测试要求以外，MEMS技术还能在缩小器件尺寸和降低成本方面大有作为。缩小器件尺寸的效果是非常显著的，我们可以看到使用了MEMS光扫描仪的WDM模块只有90×40×20mm3。而且因为MEMS不使用大量光电二极管，大大降低了器件的成本。Vqj光波通信<br /> 因为这些设备经常在现场使用，所以尺寸小、成本低就成了非常大的优势。现场技术员们到现场进行服务质量测试时再也不用带着又大又重的设备了，这就能大大提高工作效率。另外，设备价格的低廉也大大降低了维护成本，运营商们因此可以获取更多的利润。Vqj光波通信<br /> Vqj光波通信<br /> 测试需求Vqj光波通信<br /> 随着光通信网络的继续发展，光波长密度和比特率将不断地增加。应用传统测试设备已经再没有能力对这些更宽带宽的信号进行准确的测试了。Vqj光波通信<br /> MEMS技术提供了一种可行的方案去满足这些测试要求。应用MEMS光谱分析仪和WDM监测器能够以足够的速率和精度测试高速光通信网络。MEMS技术的应用还可以减小设备尺寸、提高测试方案的经济效益，这两点在选择现场测试设备时都是需要着重考虑的关键问题。Vqj光波通信<br /> Vqj光波通信<br /> Takanori Saitoh：安立公司高级研究工程师Vqj光波通信<br />
