As an example, a -55 dB reflection for singlemode fiber supplies additional optimistic specifications of the shorter lifeless zone than utilizing -forty five dB, just because -fifty five dB is usually a lessen reflection plus the detector recovers more rapidly. Also, utilizing various techniques to compute the distance could also return a shorter dead zone than what it truly is.
