What Is OTDR Blind Area?-
If the blind area is too long, some connectors may be missed, and technicians can''t identify them, which makes the work of locating potential problems even more difficult. The short attenuation blind area
What Is OTDR Blind Area?-
The OTDR produces a blind area because the OTDR''s detector is temporarily blinded by the high intensity Fresnel reflection light (mainly caused by the air gap between the OTDR connections).
