Fiber Optic Otdr Tester

Fiber optic testers include tools and equipment to perform basic inspection and cleaning basic troubleshooting and verification testers certification testers and advanced otdr testers for troubleshooting and analysis of existing fiber optic cabling.

Fiber optic otdr tester.

This light signal is reflected back from the sides of the fiber. Extended or tier 2 fiber certification supplements tier 1 testing with the addition of an optical time domain reflectometer otdr from end to end. An optical time domain reflectometer otdr is an optoelectronic instrument used to characterize an optical fiber an otdr is the optical equivalent of an electronic time domain reflectometer it injects a series of optical pulses into the fiber under test and extracts from the same end of the fiber light that is scattered rayleigh backscatter or reflected back from points along the fiber. 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.

The optical time domain reflectometer otdr is useful for testing the integrity of fiber optic cables. With the rapid advancements in fiber optic technology otdr testing methods have become indispensable to building certifying maintaining and troubleshooting fiber optic systems. When to use an otdr. 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.

An otdr trace is done by sending an optical pulse down the fiber optic cable. Later comparisons can be made between the original trace and a second trace. 00 get it as soon as fri oct 2. 00 free shipping by amazon.

The otdr is the single piece of test equipment needed to provide the most accurate and complete end to end link validation. An otdr trace is a graphical representation of power and distance of all elements of the optical fiber. Otdr optical time domain reflectometer equipment is designed to characterize optical fiber. Otdr tester 1310 1550nm 22 20db 60km multi function fiber optic tester tool with otdr vfl opm and ols functions with sc fc st lc adaptors 484 00 484.

It can verify splice loss measure length and find faults. Once saved otdr results can be used to reference the link for future testing. 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. Otdr test pulse width wavelength.
