Characterizing Coherent Optical Transmission Systems
应用文章
The needs of Big Data usage, Cloud applications, the Internet of Things (IoT) and a huge number of mobile devices are challenging the existing communication networks for wireline and wireless voice and data traffic.
The industry has adopted coherent optical transmission communication systems, which use advanced modulation schemes, to cope with the explosive demand for data transportation. This solution comes with some new requirements, which need to be understood along the whole communication link from the transmitter, through fiber cable and network elements to the receiver. The network design needs to be robust against signal distortions and link impairments.
