Otdr Launch Cable

What is a launch cable used for.

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. An otdr launch cable which connects the otdr to the link under test discloses the insertion loss and reflectance of the near. Measurement using a launch cable launch cable launch cable otdr 1m patchcord bulkhead reflective event with loss fiber under test start of fut end of fut end of launch cable these reflections will be small if the connectors are clean in good condition clean protect the launch cable connectors 1m patchcord. The launch fiber cable helps to negate blind spots or the dead zones of an otdr which occures when there is high launch power or faults near the.

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. In general there are two types of dead zones event dead zone edz and. 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 cables are designed to be used in conjunction with an otdr to measure complete link loss of a fiber.

Ftb ltc psb spsb launch test cable pulse suppressor box. Otdr testing with launch cable. This help to avoid variations in loss and distance measurements when testing. 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.

Multi mode om1 fcupc fcupc otdr launch cable 150 meters 170 00. 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. Otdr launch cable leadequipment calibration. They are also known as pulse suppressor cables launch cords launch leads receive cables or fiber rings.

Using a shorter fiber launch cable may hide the first event within the fiber quickmap s dead zone. Otdr requires some time for recovery which causes otdr dead zone. Use them to test 50 µm and 62 5 µm multimode and 9 µm single mode sc sc or lc lc terminated fibers. 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.

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. System emulation of loss length time delay and reflectance. Both a launch and receive cable are needed to measure complete link loss of a fiber with an otdr.
