以前，由于光纤技术还未广泛应用在有线电视系统，干线传输网络在系统中所占的比例最大，为降低系统的造价，提高网络的非线性失真指标及稳定性，我们在干线网络中大量应用预均衡技术，而对于分配网络，却忽略了预均衡的使用。现在，ＨＦＣ光纤ＣＡＴＶ混合网结构在有线电... Before, because the optic fiber technology has not been widely used in the cable TV system, the main transmission line has the largest proportion in the system. In order to reduce the cost of the system and improve the nonlinear distortion index and stability of the network, we have extensively applied it in the main line network Pre-balanced technology, but for the distribution network, but ignored the use of pre-balanced. Now, HFC fiber CATV hybrid network structure in the cable ...
