在用户规定的各种控制系统的基础上,提出了应用于CATV网和局部区域网的新技术的一种详细说明。由同轴电缆提供的业务愈多,终端用户提出的特殊要求也就愈多。利用同轴电缆网的保密业务和高速数据线路将要求专用设备和确保连续工作的能力。本文介绍了先进的状态监视系统,以及带有冗余放大器与利用正向馈送技术的放大器不同顿率分割的防障分路系统。 Based on the user-defined control systems, a detailed description of the new technologies applied to CATV networks and local area networks is presented. The more services provided by the coaxial cable, the more specific the end user requests. The use of coax networks for secure services and high-speed data lines will require specialized equipment and the ability to ensure continuous operation. This article describes advanced state-of-the-art monitoring systems, as well as fault-tolerant shunt systems with redundant amplifiers and amplifiers that use feed-forward technology at different rates.
