有客户反映在使用福禄克?Fiber OneShot PRO或者FiberQuickMap的时候，有时候会显示0 m（米）或者0 ft（英尺）。

Fiber OneShot PRO或者FiberQuickMap可能出现两种情况，第一：仪器端口弄脏了；第二：光纤在1米（3英尺）处损坏。

Port and or connector is dirty
It goes without saying that both the launch cord and Fiber QuickMap port need to be clean. If you are using anything other than > 98% IPA, there is a chance of a thin film being left behind that will create additional reflectance. A far better solution than IPA is something called a?Hybrid Cleaner. These cleaners are more agressive than IPA, evaporate quicker and provide a level of antistatic properties on the end faces of fibers and fiber ports.

The fiber is broken in the first?3 ft or 1?m
The minimum distance to the first reflective open is 3 ft or 1 m. It therefore makes sense to use a test cord than is greater than 1 m or 3 ft. You should ideally be using a 30 m launch fiber if you intend to evaluate the loss at the first event.
