DEAD ZONES DEFINED In regards to OTDR testing, a dead zone can be loosely defined as a portion of optical fiber beyond an event – usually a reflective event – where subsequent events cannot be

4 Attenuation Dead Zone The attenuation dead zone (ADZ) is the minimum distance after a reflective event where a non-reflective event (splice) can be measured (usually 0.5 dB).
