Fiber Optic Cable Tester Otdr

It can verify splice loss measure length and find faults.

Fiber optic cable tester otdr.

An otdr optical time domain reflectometer test is a variation on the insertion loss test that assesses the individual filaments inside of a fiber optic cable. An otdr trace is done by sending an optical pulse down the fiber optic cable. Normally it s 850 nm on multimode fiber optic cable and 1 310 nm on single mode the shorter wavelength has more back scatter so the trace will be less noisy. Optical time domain reflectometer otdr is an instrument used to create a virtual picture of a fiber optic cable route.

Later comparisons can be made between the original trace and a second trace. An otdr trace is a graphical signature of a fiber s attenuation along its length which provides insight into the performance of the link components cable connectors and splices and the quality of. It is generally less reliable than a standard insertion loss jumper test in terms of assessing the efficiency of a cable and should only be performed as a cross check. Otdr optical time domain reflectometer equipment is designed to characterize optical fiber.

Corning cable systems optical time domain reflectometer otdr provides testing flexibility by combining a rugged platform with multimode single mode or advanced testing modules. Speedwolf 1310 1550nm 37 36db otdr 7 touch screen 150km 93mi fiber optic cable tester with vfl optical power meter optical light source 1 299 00 1 299. The optical time domain reflectometer otdr is useful for testing the integrity of fiber optic cables. The otdr is also commonly used to create a picture of fiber optic cable when it is newly installed.

Extended or tier 2 fiber certification supplements tier 1 testing with the addition of an optical time domain reflectometer otdr from end to end. Exfo otdr line exfo otdrs are designed for the field. After initial tests you can make measurements at the longer wavelengths 1 300 nm on multimode and 1 550 nm on single mode and compare traces at. Resistant to shock water dust and common chemicals.

The analyzed data can provide insight into the integrity of the fibers as well as any passive optical component such as the connectors splices splitters and multiplexers along the cable path.
