Makadhi eOTDR anoshandiswa paDCI Box
OTDR optical time domain reflector, inogona kuyera urefu hwefiber, optical fiber transmission attenuation, splice attenuation uye fault location, nezvimwewo. Inogona kushandiswa pakutarisa optical fiber cable, kuvaka uye kugadzirisa fiber optic cable.
Munguva yekuedzwa kweOTDR, kupenya kunogadzirwa ne pulse generator kunofambisa LD kuti igadzire kupenya kwechiedza, uko kunopinzwa mu optical fiber kuti kuyedzwe kuburikidza ne directional coupler. Kupenya kwechiedza mu optical fiber, nekuda kwetsvina iri mukati me fiber, mabubbles uye kumwe kupararira kunoitika, mamwe acho anopararira kumashure anozivikanwa se backward scattered light (BACK SCATTERINGLIGHT), pamwe chete ne FRESENL reflected light inogadzirwa ne uneven fiber end face, pamwe chete ne reflection kudzokera ku coupler, mu photodiode, mu electrical pulse. Chiedza ichi chinoratidzwa chisina simba zvakanyanya, saka chinotumirwa kakawanda, chinounganidzwa, chinodzokororwa, chinowedzerwa, chinowedzerwa, chinoongororwa uye chinogadziriswa, uye chinozopa data kune network management platform. Chinoratidzwa ne high dynamic range uye high level of resolution.

Kushandiswa: Yakakodzera kuongororwa nekukurumidza uye kutarisirwa kwepakati pezvikanganiso zve optical fiber. Inoshandiswa paDCI Box.
