| Term (EN) | optical time domain reflectometry, OTDR (abbreviation), backscattering technique |
|---|
| Definition (EN) | A technique for characterizing an optical fibre whereby an optical pulse is transmitted through the optical fibre and the optical power of the resulting light scattered and reflected back to the input is measured as a function of time.
Note. — Useful in estimating attenuation coefficient for uniform fibres, and identifying and localising defects and localised losses. |

|---|
| Definition (SR) | Tehnika za karakterizaciju optičkog vlakna pri čemu se optički impuls prenosi kroz optičko vlakno i optička snaga dobijene rasprešene svjetlosti i reflektovane nazad na ulaz, se mjeri kao funkcija vremena.
Napomena — Korisno u procjeni koeficijenta slabljenja za homogena vlakana, i prepoznavanje i lokalizovanje nedostatka i lokalizovanih gubitaka. |
