With the use of a Dead Zone Eliminator Launch Cable, the initial section of fiber under test can be measured. The blind area (dead zone event) is placed in the launch cable allowing you to measure through the event and display the insertion loss and reflectance of the connection at the beginning of the fiber under test.

OTDR Launch Cable Box/OTDR Dead Zone Eliminator/Pulse Suppressor
The  OTDR Launch Cable is designed to aid in the testing of fiber optic cable when using an OTDR to help minimize the effects of the OTDR's launch pulse on measurement uncertainty. Using a DZE launch cable at the beginning of the fiber under test and a DZE receive cable at the end of the fiber under test allows the ability to perform loss measurments on entire length of the fiber.

The light weight unit measures only 6.25” in diameter and 1.25” high and includes a carabiner clip allowing the unit to be easily attached to belts, equipment straps and rack mounts. Units are available in any length up to 1000 meters with a choice of a variety of connectors in order to connect to virtually all OTDR and patch panel ports.
