Hello friend!

According to the OTDR principle, there are dead zones (event dead zone and attenuation dead zone) on the near-end fiber (between the test instrument and the fiber connector). After the dead zone fiber is added, the event point and fault point on the fiber link can be more accurate. It is known that the length is 150 m.
