High Speed Lightwave Component Analysis
应用文章
As lightwave transmission systems become more advanced, component designers and manufacturers must maximize the performance of their devices. For example, one parameter often used to specify digital system performance is bit error rate. However, it is difficult to specify individual components in such terms. Rather, fundamental measurements such as gain, bandwidth, frequency response and return loss can be appropriate. The lightwave component analyzer (LCA) is used to measure the linear electro-optic transmission and electrical reflection characteristics of a component as a function of modulation frequency. Calibrated and traceable measurements can be currently performed at modulation rates up to 67 GHz.
