An OTDR must always be used with a launch cable that matches the fibers being tested. Along the length of the fiber, the test pulse limits the resolution of the OTDR for finding and measuring closely spaced events, such as patchcords or broken fibers in splice closures. For best resolution, the OTDR test pulse should be set as narrowly as possible.

OTDR. The OTDR An Optical Time Domain Reflectometer — “OTDR” for short — is an electronic-optical instrument that is used to characterize optical fibers. It locates defects and faults, and determines the amount of signal loss at any point in an optical fiber. The OTDR only needs to have access to one end of a fiber to make its measurements.

All meanings which belong to OTDR abbreviation are take part only within Telecom terminology and other meanings are not found. OTDR users generally used the two-wavelengths provide the best balance of functionality and value. OTDR testing at 1310 nm and 1550 nm is normally sufficient to certify point-to-point or FTTx PON fibers and allows the detection of macro bends. Very easy for the detection of macro bends at the OTDR wavelength 1310 nm and 1550 nm. The reflection is caused by Fresnel Reflections.

As the OTDR is working, time is converted into distance, therefore, more reflections lead to more time for the detector to recover, thus resulting a longer dead zone. Dead zone limits the operation of OTDR to a large extent, making it unable to locate and resolve faults. The following picture shows the dead zone of the OTDR.

OTDR 1 1 Introducing the OTDR The OTDR allows you to characterize a fiber-optic span, usually optical fiber sections joined by splices and connectors. The optical time domain reflectometer (OTDR) provides an inside view of the fiber, and can calculate fiber length, attenuation, breaks, total return loss as well as splice, connector and total Se hela listan på lightwaveonline.com An OTDR must always be used with a launch cable that matches the fibers being tested.

Very easy for the detection of macro bends at the OTDR wavelength 1310 nm and 1550 nm. The reflection is caused by Fresnel Reflections. If you look out of your window at night, you will see your image on the window as well as what is outside. This is a Fresnel Reflection. And just as with your window, you can have too much Fresnel Reflection to the point you can hardly see anything beyond the window.
