有线电视的网络在传输中,常常会受到外界环境的影响,外界气温的变化对传输效果会产生影响,而且,在对材料的选择中和施工的质量都会对有线电视网络的运行产生影响,而且会因为技术问题导致网络运行不利,提高故障率,导致有线电视的停播。当这些问题发生后,如何有效的避免这些问题的发生,及时的排除故障是十分必要的,本文通过分析有线电视传输网络中常见的故障原因,找出检修和维护的方法。
The transmission of cable television networks is often affected by the external environment. Changes in the outside air temperature have an impact on the transmission effect. Moreover, the quality of the materials and the construction will affect the operation of the cable television network, and Due to technical problems leading to adverse network operations, improve the failure rate, leading to the cable TV off. When these problems occur, how to effectively avoid these problems and eliminate them in time is very necessary. In this paper, we analyze the common causes of faults in CATV transmission network and find out the ways to repair and maintain them.
