如何判斷fiber cable出現故障位置

详情描述：

Fiber cable出現故障多是因為人為外力、自然災害等因素導致。此時，如果需要測試fiber 
cable出現故障的位置，可根據測試距離，對照維護圖等資料判斷故障的大概位置。另外，fiber 
cable如果因槍機、刀砍、鼠害等原因造成部分故障，故障點一般較為隱蔽，因此可打開認為離故障點較近的接頭盒，斷開有問題的fiber 
cable，向兩邊測試。
如果fiber cable是終端出現故障，即尾纖終端盒內部及進局fiber 
cable出現故障，測試時會發現沒有發射信號或起始位置過低，這時需縮小測量範圍、改變脈寬，重新測試判斷故障的具體位置。

How to determine the fault location of fiber cable?
Fiber cable failures are mostly caused by factors such as man-made external 
forces and natural disasters. At this time, if you need to test the fault 
location of the fiber cable, you can judge the approximate location of the fault 
according to the test distance and the maintenance map. In addition, if the 
fiber cable is partially damaged due to gun machine, knife cut, rodent damage, 
etc., the fault point is generally concealed, so you can open the connector box 
that is considered to be closer to the fault point, disconnect the faulty fiber 
cable, and test on both sides .
If the fiber cable is a terminal failure, that is, the internal and incoming 
fiber cable of the pigtail terminal box is faulty, it will be found that there 
is no transmitted signal or the starting position is too low during the test. At 
this time, the measurement range needs to be reduced, the pulse width is 
changed, and the fault is retested to determine the fault Specific location.
