Otdr Launch Cable

Attenuation and event deadzones explained make sure that the otdr launch fiber used is of the same core diameter and connector type as the fiber link under test.

Otdr launch cable.

Noyes fiber rings from afl are a necessity when testing with an otdr. System emulation of loss length time delay and reflectance. Fluke networks otdr port saver test reference cords are short 0 3 meter 1 foot fiber optic cables that protect the port on optifiber pro otdrs when placed between the otdr port and a launch cable. Using a shorter fiber launch cable may hide the first event within the fiber quickmap s dead zone.

An otdr launch cable which connects the otdr to the link under test discloses the insertion loss and reflectance of the near. Because very long test cables are impractical to transport and use noyes designed coiled lengths of 50 µm multimode 62 5 µm multimode or single mode fiber conveniently packaged in compact rings. Fiber launch packs are designed to aid in the testing of fiber optic cable when using an otdr. Otdr launch cables are designed to be used in conjunction with an otdr to measure complete link loss of a fiber.

What is a launch cable used for. The komshine 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. Otdr launch cable leadequipment calibration. Used in conjunction with an otdr the ftb ltc psb spsb covers the otdr s dead zone enabling loss measurement on the first and last connections of a fiber under test.

Technicians use this product with optical time domain reflectometers otdr s to help minimize the effects of the otdr s launch pulse on measurement add to cart. Use them to test 50 µm and 62 5 µm multimode and 9 µm single mode sc sc or lc lc terminated fibers. Both a launch and receive cable are needed to measure complete link loss of a fiber with an otdr. They are also known as pulse suppressor cables launch cords launch leads receive cables or fiber rings.

In general there are two types of dead zones event dead zone edz and. Otdr testing with launch cable. The high power test pulse of the otdr overloads the instrument s receiver at this point no measurements can be made making the otdr blind for that period of time. Multi mode om1 fcupc fcupc otdr launch cable 150 meters 170 00.

Fiber ring otdr launch cable connects the otdr to the link under test and relays insertion loss and reflectance of the near end connection. This help to avoid variations in loss and distance measurements when testing. Otdr requires some time for recovery which causes otdr dead zone.
