Jamaica OTDR incident blind spot 1m
The event deadzone is specified as 1 meter. The fiber network has a 1 meter patch cord in the middle of two longer lengths. This limitation is caused by the instrument's inability to distinguish between backscattered light from the fiber and the reflection from the fiber end. In this article, we will discuss the concept of the OTDR's blind spot. When an optical time domain reflectometer (OTDR) detects an optical fiber link, due to the influence of reflection, it cannot detect or accurately locate event points and fault points in the optical fiber link within a certain distance (or time).
