What is an OTDR dead zone?

Time: 2021-06-26 Views: 981

Dead zones originate from reflective events (fusion splices, fibre optic connectors, pressure points, etc) along the link and can affect the OTDR's ability to accurately measure attenuation on shorter links and differentiate closely spaced events. The OTDR will become temporarily blinded by the first event it picks up and will not see upcoming events close to each other and will instead pick them up as one event. Dead zones can extend hundreds of metres from the OTDR unit but can be reduced (but never eliminated) by adjusting the pulse width in accordance with the length of the fibre.
