Dead Zone


Dead Zone at a Glance

A peak or blind spot on an OTDR trace where no measurement can be made. This is caused by a Fresnel reflection and the subsequent recovery time of the OTDR detector. Dead zones are always prominent at the very beginning of a trace or at any other high reflectance event.
