| Abstract: | This essay mainly introduces how to use the 1 550 nm technology to transform the three grades of HFC network (from county to town and to village), so that the CATV digitalization and the integrated transformation into digital TV can be realized. Then on the consideration of the future development, the essay discusses the implementation of resource sharing through 1 550 nm technology during the optical bidirectional network transformation. |
