Amakhadi e-OTDR asetyenziselwa i-DCI Box
I-OTDR optical time domain reflector, enokulinganisa ubude befayibha, ukuncitshiswa kokudluliselwa kwefayibha ye-optical, ukuncitshiswa kwe-splice kunye nendawo yempazamo, njl. Ingasetyenziswa ekujongeni ikhebula lefayibha ye-optical, ukwakhiwa kwekhebula le-fiber optic kunye nokugcinwa
Ngexesha lovavanyo lwe-OTDR, i-pulse eveliswa yi-pulse generator iqhuba i-LD ukuze ivelise ii-pulse zokukhanya, ezifakwa kwi-optical fiber ukuze zivavanywe nge-directional coupler. I-light pulse ingena kwi-optical fiber, ngenxa yokungcola ngaphakathi kwi-fiber, amaqamza kunye nokunye ukusasazeka kwenzeka, ezinye zazo zisasazeke ngasemva ezaziwa ngokuba yi-backward scattered light (BACK SCATTERINGLIGHT), kunye nokukhanya okubonisiweyo kwe-FRESENL okuveliswa bubuso be-fiber engalinganiyo, kunye nokukhanya okubuyela kwi-coupler, kwi-photodiode, kwi-electrical pulse. Olu kukhanya okubonisiweyo lubuthathaka kakhulu, ngoko ke ludluliselwa ngokuphindaphindiweyo, luqokelelwe, luphindaphindwe, lukhuliswe, lulinganiswe ngokwe-avareji kwaye lucutshungulwe, kwaye emva koko lubonelele ngedatha kwiqonga lolawulo lwenethiwekhi. Luphawulwa luluhlu oluphezulu oluguquguqukayo kunye nenqanaba eliphezulu lesisombululo.
Ishiti yedatha OI-TDR Umsebenzi Inkxaso yomgama wekhonkco le-fiber, ukuncitshiswa, ukulahleka okupheleleyo kunye nezinye iiparameter zovavanyo Islothiinombolo 1isithuba Amazibuko Ibonelela ngeendawo zovavanyo ezisi-8 (ezikhethwe yi-optical switch), ezinokudityaniswa novavanyo lwe-8-core optical fiber link. Ubude bomda obusebenzayo 1625 nm Uluhlu olutshintshayo ≥30 dB Uluhlu lobubanzi bepulse 0.02 ~ 20 us Uluhlu oluphezulu lokubhaqwa ≥80 km Ukuchaneka kovavanyo lokulahlekelwa ± 0.5 dB Ukuchaneka komlinganiselo wobubanzi <20 m Isiganeko esingaboniyo <10 m Indawo engasebenziyo yokunciphisa uxinzelelo <20 m
Isicelo: Ifanelekile ekuxilongweni ngokukhawuleza kunye nolawulo oluphakathi lweziphene zefayibha ye-optical. Isetyenziselwa i-DCI Box.
