Amakarita ya OTDR akoreshwa kuri DCI Box
Akamenyetso k'igihe cy'amashanyarazi ka OTDR, gashobora gupima uburebure bwa fibre, kugabanya uburyo bwo kohereza fibre, kugabanya uburyo bwo gukwirakwiza splice n'aho ikibazo giherereye, n'ibindi. Gashobora gukoreshwa mu kugenzura insinga za fibre, kubaka no kubungabunga insinga za fibre optique.
Mu gihe cy'igerageza rya OTDR, umuvuduko w'amashanyarazi ukorwa na mashini ikora impumuro (pulse generator) uyobora LD kugira ngo ikore imivuduko y'urumuri, ishyirwa muri fibre optique kugira ngo igeragezwe binyuze mu gikoresho gihuza icyerekezo. Umuvuduko w'urumuri ujya muri fibre optique, bitewe n'imyanda iri muri fibre, uduce duto n'ibindi bikwirakwira, bimwe muri byo bigatatana inyuma bizwi nka backward scattered light (BACK SCATTERINGLIGHT), hamwe n'urumuri rwa FRESENL rugaragara rukomoka ku gice cy'inyuma cy'umuvuduko utangana, hamwe n'urumuri rugaruka kuri coupler, muri photodiode, mu muvuduko w'amashanyarazi. Uru rumuri rwagaragaye ni ruke cyane, bityo rwoherezwa kenshi, rugakusanywa, rusubirwamo, rwongerwa, rushyirwa mu byiciro kandi rugatunganywa, hanyuma rugatanga amakuru kuri platforme yo gucunga umuyoboro. Rurangwa n'uburyo bwo hejuru bwo guhindura imiterere y'urumuri n'urwego rwo hejuru rwo gusubiza ibintu mu buryo.
Urupapuro rw'amakuru OTDR Imikorere Inkunga ku ntera y'urusobe rw'imiyoboro, kugabanuka k'umuvuduko, igihombo cyose n'ibindi bipimo by'ikizamini Agace k'imbugaumubare 1umwanya Ibyambu Itanga uburyo 8 bwo gupima (bwatoranyijwe na switch y'urumuri), bushobora guhuzwa n'uburyo 8 bwo gupima fibre y'urumuri Uburebure bw'uburebure bw'imikorere 1625 nm Uruhererekane ruhinduka ≥30 dB Ubugari bw'ingufu 0.02 ~ 20 us Intera ntarengwa yo gupima ≥80 km Uburyo ikizamini cyo gutakaza gihagaze neza ± 0.5 dB Ubuziranenge bwo gupima uburebure <20 m Gutabona ibirori <10 m Agace kadakomeye ko kugabanya igihe cyo ... <20 m
Porogaramu: Irakwiriye mu gusuzuma vuba no gucunga neza amakosa ya fibre optique. Ikoreshwa kuri DCI Box.
