任何一个CATV网络,无论传输媒介是光缆或是电缆,也无论所用器材质量有多好,施工质量多高,它都是由成千上万的有源和无源器件分布的,启用后都会出现各种各样的故障,而且运行时间越长故障越多。网络出现故障后,用户看不好必须及时维修,责任心和维修技巧决定解决网络故障的效率,维修的质量决定了故障再次发生的几率。有人认为有线电视维护员技术含量不高,谁都能干,但我认为能干和能干得好是有很大区别,水平高的维修员,在很短的时间里,运用所掌握的知识和在实践中积累的经验,找到故障的根本并及时排出,而有的维护员责任心和维修能力欠缺,不动脑不分析,头痛医头,脚痛医脚,盲目动手,造成新的故障隐患,当好一名维修员除责任心外,最基本的网络三个组件电缆、分支分配器、放大器必须了解掌握其原理、特性以及相关因果关系。
Any CATV network, regardless of whether the transmission medium is a fiber optic cable or a cable, and regardless of the quality of the equipment used and the quality of the construction, is a distributed network of thousands of active and passive devices that, when enabled, A variety of faults, and the longer the running time the more faults. Network failure, the user can not see bad repair, responsibility and maintenance skills decided to solve the efficiency of network failure, the quality of maintenance determines the probability of failure again. Some people think that cable TV maintainers are not technically advanced and can do anything but I think that being able to do well and doing well is a very different and high-level maintenance worker. In a very short period of time, I use my knowledge and practice In the accumulation of experience to find the root cause of the failure and timely discharge, and some maintenance staff responsible and lack of maintenance capacity, brains do not analyze, headaches, feet and feet, blind hands-on, resulting in a new hidden trouble, when good In addition to a maintenance staff responsible, the most basic network of three components cable, branch distributor, amplifier must understand its principles, characteristics and related causal relationship.
