| Abstract: | We discuss digital TV optical transmission applications and requirement. By comparison, it shows that 1550 CATV optical transmission technology combining optical dispersion has very strong competition advantage in technology and cost, especially in ultra-long distance status applications. We analyze the questions of 1550 digital TV optical transmission and whether optical dispersion is needed. We educe that the optical dispersion is needed well in 1550 ultra-long distance digital TV optical transmission system. At last, we present a example system of 1550 digital and analog TV transmission networks. |
