Otdr launch cables are designed to be used in conjunction with an otdr to measure complete link loss of a fiber.
Otdr launch cable.
This help to avoid variations in loss and distance measurements when testing.
Otdr requires some time for recovery which causes otdr dead zone.
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.
They are also known as pulse suppressor cables launch cords launch leads receive cables or fiber rings.
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.
Ftb ltc psb spsb launch test cable pulse suppressor box.
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.
Fiber ring otdr launch cable connects the otdr to the link under test and relays insertion loss and reflectance of the near end connection.
What is a launch cable used for.
Both a launch and receive cable are needed to measure complete link loss of a fiber with an otdr.
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.
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.
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.
An otdr launch cable which connects the otdr to the link under test discloses the insertion loss and reflectance of the near.
Using a shorter fiber launch cable may hide the first event within the fiber quickmap s dead zone.
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.
Otdr testing with launch cable.
System emulation of loss length time delay and reflectance.
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.
In general there are two types of dead zones event dead zone edz and.
Fiber launch packs are designed to aid in the testing of fiber optic cable when using an otdr.
