Fiber Optic Cable Tester Otdr

Later comparisons can be made between the original trace and a second trace.

Fiber optic cable tester otdr.

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. It can verify splice loss measure length and find faults. 00 25 37 oz get it as soon as wed sep 23.

This light signal is reflected back from the sides of the fiber. An otdr trace is done by sending an optical pulse down the fiber optic cable. Optical time domain reflectometer otdr is an instrument used to create a virtual picture of a fiber optic cable route. 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.

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. Resistant to shock water dust and common chemicals. The otdr is also commonly used to create a picture of fiber optic cable when it is newly installed. Corning cable systems optical time domain reflectometer otdr provides testing flexibility by combining a rugged platform with multimode single mode or advanced testing modules.

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. The optical time domain reflectometer otdr is useful for testing the integrity of fiber optic cables. 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. 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.
