Optical time-domain reflectometer.
An optical time-domain reflectometer is an optoelectronic instrument used to characterize an optical fiber. An OTDR is the optical equivalent of an electronic time domain reflectometer.
What is the OTDR used for?
An Optical Time Domain Reflectometer (OTDR) is an important instrument used by organizations to certify the performance of new fiber optics links and detect problems with existing fiber links.
What is OTDR and how does it work?
An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. ... 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.
How does OTDR test fiber?
1. Turn on OTDR and allow time to warm-up.
2. Clean all connectors and mating adapters.
3. Attach launch cable to OTDR. Attach receive cable (if used) to far end of cable.
4. Set up test parameters on OTDR.
5. Attach cable to test to end of launch cable. Attach receive cable (if used) to far end of cable.
6. Acquire trace.
How does OTDR work?
The laser emits a pulse of light at a specific wavelength, this pulse of light travels along the fiber being tested, as the pulse moves down the fiber portions of the transmitted light are reflected/refracted or scattered back down the fiber to the photo detector in the OTDR.
How long does OTDR testing take?
Therefore, reflectometer testing may not be economically justifiable. It typically takes at least 3 minutes for a skilled OTDR technician with high-quality equipment to obtain one trace. Printing out the trace adds another 2 to 3 minutes per fiber.
How do you analyze OTDR results?
First place one of the markers or cursors (usually called 1 or A on your OTDR) just before the reflectance peak. Next, place the second marker (referred to as 2 or B on your OTDR) just after the reflectance peak. The OTDR will calculate the loss between the two markers.
An Optical Time-Domain Reflectometer (OTDR) is an optical test instrument used to detect light loss in a single fiber.
