Uvavanyo lwe-fiber optic luphawu olubalulekileyo lokuqinisekisa ukuthembeka, ukusebenza, kunye nomgangatho weenkqubo zonxibelelwano lwe-fiber optic. Olu vavanyo lwenziwa ukuqinisekisa ukuba iintambo ze-fiber optic ezifakiweyo, izihlanganisi, ii-splices, kunye nezinye izinto ziyahlangabezana nemigangatho kunye neenkcukacha ezifunekayo. Nantsi ingcaciso ebanzi yemiba ephambili yovavanyo lwe-fiber optic:

Uvavanyo lwangaphambi kokufakwa:

Ngaphambi kokufaka iintambo ze-fiber optic, kubalulekile ukwenza uvavanyo lwangaphambi kokufakela ukuze kuvavanywe ukuthembeka kweentambo kwaye kuchongwe naziphi na iingxaki ezinokubakho. Oku kungabandakanya ukuhlolwa okubonakalayo, ukujonga ubude beentambo, kunye nokuqinisekisa iinkcukacha zeentambo.

Uvavanyo Lokulahlekelwa Kokufakwa:

Uvavanyo lokulahleka kokufakwa lulinganisa ukulahleka kwamandla esignali njengoko ukukhanya kuhamba ngentambo ye-fiber optic. Olu vavanyo ludla ngokwenziwa kusetyenziswa umthombo wokukhanya kunye nemitha yamandla ukulinganisa ukulahleka kwamandla okubangelwa zizihlanganisi, ii-splices, kunye nokugoba kwifayibha.

Uvavanyo lokulahleka kokubuya:

Uvavanyo lokulahleka kokubuya luvavanya ubungakanani bokukhanya okubonakaliswa ngasemva kumthombo ngenxa yokungafezeki kwizixhobo ze-fiber optic. Ukulahleka kokubuya okuphezulu kunokubonisa ukupheliswa kwesixhumi okanye ezinye iingxaki ezinokonakalisa umgangatho wesiginali.

I-Optical Time Domain Reflectometry (OTDR):

I-OTDR sisixhobo esinamandla sokuxilonga esisetyenziselwa ukuchaza iprofayili yokulahleka kunye nokuncitshiswa kweentambo ze-fiber optic. Ithumela iipulses ezimfutshane zokukhanya kwi-fiber kwaye ihlalutye ukukhanya okungasemva ukuze yenze iprofayili yobude be-fiber kunye neempawu zokuncitshiswa kwayo. I-OTDR iluncedo ngokukodwa ekuchongeni ukuqhekeka kwe-fiber, ukugoba, kunye nokulahleka kwe-splice.

Uvavanyo lwePolarization Mode Dispersion (PMD):

Uvavanyo lwe-PMD luvavanya imiphumo yokusasazwa kwemo ye-polarization, enokubangela ukuphazamiseka kwesignali kwaye inciphise umgama wokudluliselwa kunye ne-bandwidth yeenkqubo ze-fiber optic. Uvavanyo lwe-PMD lunceda ukuqinisekisa ukuba iinethiwekhi ze-fiber optic zinokuxhasa ukuhanjiswa kwedatha ngesantya esiphezulu ngaphandle kokonakala kwesignali.

Uvavanyo lokuSasazwa kweChromatic:

Uvavanyo lwe-Chromatic dispersion lulinganisa ukwanda kwee-optical pulses njengoko zihamba kwi-fiber ngenxa yee-wavelengths ezahlukeneyo ezihamba ngesantya esahlukileyo. Olu vavanyo lubalulekile ekumiseleni amazinga aphezulu edatha anokufikelelwa kunye nemigama yokudluliselwa kweenkqubo ze-fiber optic.

Uvavanyo lweNdalo:

Iintambo ze-fiber optic zihlala ziphantsi kweemeko ezahlukeneyo zendalo ngexesha lokufakwa nokusebenza, ezinje ngokutshintsha kobushushu, ukufuma, kunye noxinzelelo loomatshini. Uvavanyo lwendalo luvavanya ukusebenza kwezixhobo ze-fiber optic phantsi kweemeko ezahlukeneyo zendalo ukuqinisekisa ukuthembeka nokuqina.

Isiqinisekiso kunye namaxwebhu:

Nje ukuba uvavanyo lugqityiwe, iingxelo zesatifikethi kunye namaxwebhu aveliswa ukuqinisekisa ukuba ukufakwa kwe-fiber optic kuyahlangabezana nemigangatho kunye neenkcukacha ezifunekayo. Olu xwebhu lubalulekile ekuthobeleni imigaqo yoshishino kunye nokuqinisekisa umgangatho kunye nokusebenza kwenethiwekhi ye-fiber optic.

Ngokubanzi, uvavanyo lwe-fiber optic ludlala indima ebalulekileyo ekuqinisekiseni ukuthembeka, ukusebenza, kunye nomgangatho weenkqubo zonxibelelwano lwe-fiber optic, ukusuka ekufakweni kokuqala ukuya kulondolozo oluqhubekayo kunye nokusombulula iingxaki. Ngokwenza uvavanyo olupheleleyo, abaqhubi benethiwekhi banokuchonga kwaye basombulule imiba ngendlela ekhawulezileyo, baqinisekise ukusebenza kakuhle kwaye banciphise ixesha lokungasebenzi.
