摘要
文章讨论了ＣＡＴＶ系统前端载噪比（Ｃ／Ｎ）Ｈ指标的合理选取及合理利用。从而保证干线传输系统的性价比、可靠性和有效提高分配网络的效率。
Rational selection and usage of carrier to noise ratio in CATV headend is discussed in this paper so as to ensure cost effectiveness and reliability of the trunk transmission system and improve the efficiency in distribution network.
