Ukuqinisekisa iimpawu zokusetyenziswa kwezibonakaliso zokudluliselwa kwe-optical ezikude nezilahleka kancinci, umgca wentambo ye-fiber optic kufuneka uhlangabezane neemeko ezithile zokusingqongileyo. Nakuphi na ukugoba okuncinci okanye ukungcola kweentambo ze-optical kunokubangela ukuncitshiswa kwezibonakaliso ze-optical kwaye kuphazamise nonxibelelwano.
1. Ubude bomgca wokuhambisa intambo ye-fiber optic
Ngenxa yeempawu ezibonakalayo zeentambo ze-optical kunye nokungalingani kwenkqubo yokuvelisa, imiqondiso ye-optical esasazwa kuzo ihlala isasazeka kwaye ifunxwa. Xa ikhonkco lentambo ye-fiber optic lide kakhulu, liya kubangela ukuba ukuncitshiswa kwesignali ye-optical yekhonkco lonke kudlule iimfuno zocwangciso lwenethiwekhi. Ukuba ukuncitshiswa kwesignali ye-optical kukhulu kakhulu, kuya kunciphisa isiphumo sonxibelelwano.
2. I-engile yokugoba yokubekwa kwentambo ye-optical inkulu kakhulu
Ukugoba kunye nokuncitshiswa kokucinezelwa kweentambo ze-optical ngokuyintloko kubangelwa kukuguquka kweentambo ze-optical, okukhokelela ekungakwazini ukwanelisa ukubonakaliswa okupheleleyo ngexesha lenkqubo yokudluliselwa kwe-optical. Iintambo ze-fibre optic zinomlinganiselo othile wokugoba, kodwa xa intambo ye-fiber optic igobile kwi-engile ethile, iya kubangela utshintsho kwicala lokusasazeka kwesignali ye-optical kwintambo, nto leyo ebangela ukugoba okuncinci. Oku kufuna ingqalelo ekhethekileyo ekushiyeni ii-engile ezaneleyo zokufakelwa kwentambo ngexesha lokwakhiwa.
3. Intambo ye-fiber optic icinezelwe okanye yaphukile
Le yeyona mpazamo ixhaphakileyo xa intambo ye-optical ingasebenzi. Ngenxa yamandla angaphandle okanye iintlekele zemvelo, iintambo ze-optical zinokuba nokugoba okuncinci okanye ukwaphuka. Xa ukwaphuka kwenzeka ngaphakathi kwebhokisi ye-splice okanye intambo ye-optical, akunakubonwa ngaphandle. Nangona kunjalo, kwindawo yokuqhekeka kwentambo ye-optical, kuya kubakho utshintsho kwi-refractive index, kunye nokulahleka kokubonakalisa, okuya kunciphisa umgangatho wesignali edluliselweyo yentambo. Kule ndawo, sebenzisa i-OTDR optical cable tester ukuze ufumane incochoyi yokubonakalisa kwaye ufumane indawo yokuthomalalisa ukugoba kwangaphakathi okanye indawo yokuqhekeka kwentambo ye-optical.
4. Ukusilela kokuhlanganiswa kwe-fiber optic joint construction
Kwinkqubo yokubeka iintambo ze-optical, ii-fiber fusion splicers zihlala zisetyenziselwa ukudibanisa amacandelo amabini eentambo ze-optical zibe linye. Ngenxa yokudibanisa i-fiber yeglasi kumaleko ophambili wentambo ye-optical, kuyimfuneko ukusebenzisa i-fusion splicer ngokuchanekileyo ngokohlobo lwentambo ye-optical ngexesha lenkqubo yokudibanisa indawo yokwakha. Ngenxa yokuba umsebenzi awuhambelani nemigaqo yokwakha kunye notshintsho kwindawo yokwakha, kulula ukuba i-optical fiber ingcoliswe bukungcola, nto leyo ebangela ukungcola okuxutywe ngexesha lenkqubo yokudibanisa i-fusion kwaye ibangele ukwehla komgangatho wonxibelelwano lwekhonkco lonke.
5. Ububanzi bentambo ye-fiber core buyahluka
Ukufakwa kwentambo ye-fiber optic kudla ngokusebenzisa iindlela ezahlukeneyo zokunxibelelana ezisebenzayo, ezifana noqhagamshelo lwe-flange, ezisetyenziswa kakhulu kuqhagamshelo lwenethiwekhi yekhompyutha kwizakhiwo. Uqhagamshelo olusebenzayo luhlala lunelahleko eziphantsi, kodwa ukuba ubuso bokugqibela be-optical fiber okanye i-flange abucocekanga ngexesha loqhagamshelo olusebenzayo, ububanzi be-core optical fiber buhlukile, kwaye ijoyinti ayiqinanga, iya kwandisa kakhulu ukulahleka kwejoyinti. Ngokusebenzisa i-OTDR okanye uvavanyo lwamandla e-dual end, iimpazamo zokungafani kobubanzi be-core zinokufunyanwa. Kufuneka kuqatshelwe ukuba i-single-mode fiber kunye ne-multi-mode fiber zineendlela ezahlukeneyo zokudlulisela, ubude bamaza, kunye neendlela zokunciphisa ngaphandle kobubanzi be-core fiber, ngoko ke azinakuxutywa.
6. Ungcoliseko lwe-fiber optic connector
Ungcoliseko lwamalungu efayibha yomsila kunye nokufuma kwefayibha zezona zinto ziphambili ezibangela ukungasebenzi kakuhle kwekhebula le-optical. Ingakumbi kwiinethiwekhi zangaphakathi, kukho iifayibha ezininzi ezimfutshane kunye nezixhobo ezahlukeneyo zokutshintsha inethiwekhi, kwaye ukufakwa nokususwa kwezihlanganisi zefayibha optic, ukutshintshwa kweflange, kunye nokutshintsha kwenzeka rhoqo. Ngexesha lokusebenza, uthuli oluninzi, ukulahleka kokufakwa kunye nokukhupha, kunye nokuchukumisa ngeminwe kunokwenza i-fiber optic connector ibe mdaka ngokulula, okubangela ukungakwazi ukulungisa indlela ye-optical okanye ukuncitshiswa kokukhanya okugqithisileyo. Iiswabhu zotywala kufuneka zisetyenziswe ekucoceni.
7. Ukupholisha kakubi amalungu
Ukupholishwa kakubi kwamalungu kukwayenye yezona mpazamo ziphambili kwiikhonkco ze-fiber optic. I-fiber optic cross-section efanelekileyo ayikho kwindawo yokwenyani, kwaye kukho ezinye ii-undulations okanye ii-slopes. Xa ukukhanya kwikhonkco le-optical cable kudibana ne-cross-section enjalo, umphezulu odibeneyo ongaqhelekanga ubangela ukusasazeka kwe-diffuse kunye nokubonakaliswa kokukhanya, okwandisa kakhulu ukuncitshiswa kokukhanya. Kwigophe lomvavanyi we-OTDR, indawo yokuncitshiswa kwecandelo elipholishwe kakubi inkulu kakhulu kuneyobuso obuqhelekileyo bokuphela.
Iziphene ezinxulumene ne-fibre optic zezona ziphene zibonakalayo nezixhaphakileyo ngexesha lokulungisa okanye lokulungisa. Ke ngoko, kufuneka isixhobo ukujonga ukuba ukukhutshwa kokukhanya kwe-fiber optic kuyinto eqhelekileyo na. Oku kufuna ukusetyenziswa kwezixhobo zokuxilonga iimpazamo ze-fiber optic, ezifana neemitha zamandla okukhanya kunye neepeni zokukhanya ezibomvu. Iimitha zamandla okukhanya zisetyenziselwa ukuvavanya ukulahleka kokudluliselwa kwe-fiber optic kwaye kulula kakhulu ukuyisebenzisa, kulula, kwaye kulula ukuzisebenzisa, nto leyo eyenza zibe lolona khetho lufanelekileyo lokusombulula iingxaki ze-fiber optic. Ipeni yokukhanya ebomvu isetyenziselwa ukufumana ukuba yeyiphi idiski ye-fiber optic ekwi-fiber optic. Ezi zixhobo zimbini zibalulekileyo zokusombulula iingxaki ze-fiber optic, kodwa ngoku imitha yamandla okukhanya kunye nepeni yokukhanya ebomvu zidityaniswe zibe sisixhobo esinye, esilula ngakumbi.
