Ukuhlolwa kwe-Fiber optic core reflection test kwenziwa nge-Optical Time Domain Reflectometer (OTDR). Okuyidivayisi esetshenziselwa ukuthola ngokunembile amaphutha kusixhumanisi se-fiber optical yamanethiwekhi okuxhumana. I-OTDR ikhiqiza ukushaya kwenhliziyo ngaphakathi kwefayibha ukuze ihlolwe amaphutha noma ukukhubazeka. Imicimbi ehlukene ngaphakathi kwefayibha idala i-Rayleigh back scatter. Ama-pulses abuyiselwa ku-OTDR futhi amandla awo abe eselinganiswa futhi abalwe njengomsebenzi wesikhathi futhi ahlelwe njengomsebenzi we-fiber stretch. Amandla nesignali ebuyisiwe ichaza ngendawo kanye nokuqina kwephutha elikhona. Akukhona nje ukulungisa kuphela, kodwa futhi nezinsiza zokufakwa kwelayini yokubona zisebenzisa ama-OTDR.

I-OTDR iwusizo ekuhloleni ubuqotho bezintambo ze-fiber optic. Ingaqinisekisa ukulahleka kwe-splice, ilinganise ubude futhi ithole amaphutha. I-OTDR iphinde isetshenziselwe ukwenza "isithombe" sentambo ye-fiber optic uma isanda kufakwa. Kamuva, kungenziwa ukuqhathanisa phakathi komkhondo wokuqala kanye nesesibili esithathwe uma kuphakama izinkinga. Ukuhlaziya ukulandelelwa kwe-OTDR kuhlala kwenziwa kube lula ngokuba nemibhalo evela kumkhondo wangempela owadalwa ngenkathi kufakwa ikhebula. I-OTDR ikubonisa lapho izintambo zinqanyulwa khona futhi iqinisekisa ikhwalithi yamafayibha, uxhumo kanye neziqephu. Ukulandelelwa kwe-OTDR kuphinde kusetshenziselwe ukuxazulula inkinga, njengoba kungabonisa lapho ukuphuka kuyifayibha lapho ukulandelelwa kuqhathaniswa nemibhalo yokufaka.

I-Jera iqhubeke nokuhlola izintambo ze-FTTH zokuwisa kumaza wamaza (1310,1550 kanye no-1625 nm). Sisebenzisa i-EXFO FTB-1 kulokhu kuhlolwa kwekhwalithi. Ukuhlola ikhwalithi yezintambo zethu ukuqinisekisa ukuthi ikhasimende lethu lingathola imikhiqizo ehlangabezana nezidingo zekhwalithi.

Senza lokhu kuhlola kuwo wonke amakhebuli esiwakhiqizayo.
Ilabhorethri yethu yangaphakathi iyakwazi ukuqhubeka nochungechunge olunjalo lokuhlola okujwayelekile okuhlobene.
Siyakwamukela ukuxhumana nathi ukuze uthole ulwazi olwengeziwe.
