Ukuqinisekisa izici zokusetshenziswa kwezibonakaliso zokudlulisa ukukhanya ezikude neziphansi, umugqa wekhebula le-fiber optic kumele uhlangabezane nezimo ezithile zemvelo. Noma yikuphi ukugoba okuncane noma ukungcola kwezintambo ze-optical kungabangela ukuncishiswa kwezibonakaliso zokukhanya futhi kuphazamise nokuxhumana.
1. Ubude bomugqa womzila wekhebula le-fiber optic
Ngenxa yezici zomzimba zezintambo ze-optical kanye nokungalingani enqubweni yokukhiqiza, izimpawu ze-optical ezisakazwa kuzo zihlala zisakazeka futhi zimuncwa. Uma isixhumanisi sekhebula le-fiber optic side kakhulu, kuzokwenza ukuthi ukuncishiswa okuphelele kwesignali ye-optical yesixhumanisi sonke kudlule izidingo zokuhlela inethiwekhi. Uma ukuncishiswa kwesignali ye-optical kukhulu kakhulu, kuzonciphisa umphumela wokuxhumana.
2. I-engeli yokugoba yokubekwa kwekhebula le-optical inkulu kakhulu
Ukugoba kanye nokuncishiswa kokucindezelwa kwezintambo ze-optical empeleni kubangelwa ukuguquguquka kwezintambo ze-optical, okuholela ekungakwazini ukwanelisa ukubonakaliswa okuphelele ngesikhathi senqubo yokudlulisa i-optical. Izintambo ze-fibre optic zinezinga elithile lokugoba, kodwa lapho ikhebula le-fiber optic ligobile nge-engeli ethile, lizobangela ushintsho endleleni yokusabalala kwesignali ye-optical kukhebula, okuholela ekuncishisweni kokugoba. Lokhu kudinga ukunakwa okukhethekile ekushiyeni ama-engeli anele okuxhuma izintambo ngesikhathi sokwakhiwa.
3. Ikhebula le-fiber optic liyacindezelwa noma liphukile
Leli yiphutha elivame kakhulu ekuhlulekeni kwekhebula le-optical. Ngenxa yamandla angaphandle noma izinhlekelele zemvelo, imicu ye-optical ingase ibhekane nokugoba okuncane okungajwayelekile noma ngisho nokuphuka. Lapho ukuphuka kwenzeka ngaphakathi kwebhokisi le-splice noma ikhebula le-optical, akunakutholakala ngaphandle. Kodwa-ke, endaweni yokuphuka kwefayibha, kuzoba noshintsho ku-refractive index, kanye nokulahlekelwa ukubonakaliswa, okuzolimaza ikhwalithi yesignali edlulisiwe yefayibha. Kuleli qophelo, sebenzisa umhloli wekhebula le-optical le-OTDR ukuthola ukuphakama kokubonakaliswa nokuthola iphuzu lokugoba kwangaphakathi noma iphuzu lokuphuka kwefayibha ye-optical.
4. Ukwehluleka kokuhlanganiswa kwe-fiber optic joint construction
Enkambisweni yokubeka izintambo ze-optical, izixhumi ze-fiber fusion zivame ukusetshenziswa ukuhlanganisa izingxenye ezimbili zezintambo ze-optical zibe yinye. Ngenxa yokuhlanganiswa kwe-fiber yengilazi engxenyeni eyinhloko yekhebula le-optical, kuyadingeka ukusebenzisa i-fusion splicer ngendlela efanele ngokohlobo lwekhebula le-optical ngesikhathi senqubo yokuhlanganiswa kwe-fusion endaweni yokwakha. Ngenxa yokusebenza okungahambisani nemininingwane yokwakha kanye nezinguquko endaweni yokwakha, kulula ukuthi i-optical fiber ingcoliswe ukungcola, okuholela ekungcoleni okuxubene ngesikhathi senqubo yokuhlanganiswa kwe-fusion futhi kubangele ukwehla kwekhwalithi yokuxhumana yesixhumanisi sonke.
5. Ububanzi bentambo ye-fiber core buyahlukahluka
Ukufakwa kwekhebula le-fibre optic kuvame ukusebenzisa izindlela ezahlukahlukene zokuxhuma ezisebenzayo, njengokuxhumeka kwe-flange, okuvame ukusetshenziswa ekufakweni kwenethiwekhi yekhompyutha ezakhiweni. Ukuxhumeka okusebenzayo ngokuvamile kunokulahlekelwa okuphansi, kodwa uma ubuso bokugcina be-fiber optical noma i-flange bungahlanzekile ngesikhathi sokuxhumeka okusebenzayo, ububanzi be-fiber optical core buhlukile, futhi ijoyinti lingaqinile, kuzokwandisa kakhulu ukulahlekelwa kwamalunga. Ngokusebenzisa i-OTDR noma ukuhlolwa kwamandla okuphela okubili, amaphutha okungafani kobubanzi be-core angatholakala. Kufanele kuqashelwe ukuthi i-fiber yemodi eyodwa kanye ne-fiber yemodi eminingi inezindlela zokudlulisela ezihlukile ngokuphelele, ubude bamaza, kanye nezindlela zokunciphisa ngaphandle kobubanzi be-fiber eyinhloko, ngakho-ke azikwazi ukuhlanganiswa.
6. Ukungcola kwesixhumi se-fiber optic
Ukungcola kwamalunga e-tail fiber kanye nomswakama we-fiber skipping yizona zimbangela eziyinhloko zokwehluleka kwekhebula le-optical. Ikakhulukazi kumanethiwekhi angaphakathi, kunezintambo eziningi ezimfushane kanye namadivayisi ahlukahlukene okushintsha inethiwekhi, futhi ukufakwa nokususwa kwezixhumi ze-fiber optic, ukushintshwa kwe-flange, kanye nokushintsha kuvame kakhulu. Ngesikhathi senqubo yokusebenza, uthuli oluningi, ukulahlekelwa kokufakwa nokukhishwa, kanye nokuthinta ngomunwe kungenza kalula isixhumi se-fiber optic singcole, okuholela ekungakwazini ukulungisa indlela ye-optical noma ukuncishiswa kokukhanya ngokweqile. Ama-swab otshwala kufanele asetshenziswe ekuhlanzeni.
7. Ukupholisha kabi esibayeni
Ukupholisha kabi amalunga nakho kungenye yamaphutha amakhulu ezixhumanisini ze-fiber optic. I-cross-section ye-fiber optic efanele ayikho endaweni yangempela, futhi kukhona ama-undulations noma ama-slopes. Lapho ukukhanya ku-optical cable link kuhlangana ne-cross-section enjalo, ubuso obungajwayelekile bamalunga bubangela ukusabalala okusabalele kanye nokubonakaliswa kokukhanya, okwandisa kakhulu ukuncishiswa kokukhanya. Ekhoneni lomhloli we-OTDR, indawo yokuncishiswa kwengxenye epholishwe kabi inkulu kakhulu kuneyobuso obujwayelekile bokuphela.
Amaphutha ahlobene ne-fibre optic yiwona amaphutha abonakala kakhulu futhi avame kakhulu ngesikhathi sokulungisa iphutha noma ukulungiswa. Ngakho-ke, kudingeka ithuluzi ukuhlola ukuthi ukukhishwa kokukhanya kwe-fiber optic kuyinto evamile yini. Lokhu kudinga ukusetshenziswa kwamathuluzi okuxilonga amaphutha e-fiber optic, njengemitha yamandla optical kanye namapeni okukhanya abomvu. Amamitha wamandla optical asetshenziselwa ukuhlola ukulahlekelwa kokudluliselwa kwe-fiber optic futhi kulula kakhulu ukuwasebenzisa, kulula, futhi kulula ukuwasebenzisa, okwenza abe yisinqumo esingcono kakhulu sokuxazulula amaphutha e-fiber optic. Ipeni lokukhanya elibomvu lisetshenziselwa ukuthola ukuthi iyiphi idiski ye-fiber optic i-fiber optic ekuyo. Lawa mathuluzi amabili abalulekile okuxazulula amaphutha e-fiber optic, kodwa manje imitha yamandla optical kanye nepeni lokukhanya elibomvu kuhlanganiswe kube ithuluzi elilodwa, okuyinto elula kakhulu.
