摘要:民航空管系統(tǒng)長距離、大帶寬業(yè)務(wù)傳輸大都采用光纜。文章以民航空管單位之間光纜故障為例,借助光功率計、OTDR等儀表,判斷故障原因,定位故障點和衰減過大的線路,提出故障排查和線路優(yōu)化方法,最終達到排除傳輸隱患的目的。

關(guān)鍵詞:長途光纜;傳輸隱患;故障分析;線路優(yōu)化

Abstract: Between civil ATC centers, optical cables are always used to transmiss long distance, high-bandwidth service. This paper takes the optical cable fault as an example, to determine the cause and the of the cable failure and the location of the attenuation by using optical power and meter OTDR meter. Then, it propose methods of troubleshooting and route optimization to eliminate hidden dangers of transmission in the end.

Key words: long distance optical cable; transmission hidden danger; fault analysis; route optimization
