Kwiminyaka embalwa edlulileyo, i-fiber optic cable iye yafikeleleka ngakumbi.Ngoku isetyenziswa kwizicelo ezininzi ezifuna ukunganyangeki ngokupheleleyo kuphazamiseko lombane.I-Fiber ifanelekile kwiinkqubo eziphezulu zedatha ezifana ne-FDDI, i-multimedia, i-ATM, okanye nayiphi na enye inethiwekhi efuna ukuhanjiswa kweefayile ezinkulu, ezichitha ixesha.
Olunye uncedo lwefiber optic cable phezu kobhedu lubandakanya:
• Umgama omkhudlwana-Ungabaleka ifayibha ukuya kuthi ga kwiikhilomitha eziliqela.• Ukuthomalalisa okuphantsi-Imiqondiso yokukhanya ihlangabezana nokuxhathisa okuncinci, ngoko idatha inokuhamba kude.
• Ukhuseleko-Iimpompo kwintambo yefiber optic kulula ukuyibona.Ukuba itephulwe, intambo ivuza ukukhanya, ibangela ukuba inkqubo yonke ingaphumeleli.
• I-bandwidth enkulu-iFiber inokuthwala idatha eninzi kunobhedu.• I-Immunity-Fiber optics ikhuselekile ekuphazamisekeni.
Imowudi enye okanye imowudi eninzi?
I-fiber yemowudi enye ikunika izinga eliphezulu losulelo kunye nokuya kuthi ga kwi-50 umgama omde ngaphezu kwe-multimode, kodwa ikwaxabisa ngaphezulu.I-fiber yemowudi enye inombindi omncinci kakhulu kune-multimode fiber-ngokuqhelekileyo i-5 ukuya kwi-10 microns.Ligatya lokukhanya elinye kuphela elinokuhanjiswa ngexesha elithile.Undoqo omncinci kunye ne-lightwave enye ngokuqinisekileyo isusa nayiphi na impazamo enokuthi ibangele iipulse zokukhanya ezidlulayo, ukubonelela ngokunciphisa umqondiso omncinci kunye nezantya eziphezulu zothumelo lwalo naluphi na uhlobo lwentambo yefiber.
I-Multimode fiber ikunika i-bandwidth ephezulu kwizantya eziphezulu kwimigama emide.Amaza okukhanya asasazwa kwiindlela ezininzi, okanye iindlela, njengoko ehamba kumbindi wentambo.I-multimode fiber core diameters yi-50, 62.5, kunye ne-100 micrometers.Nangona kunjalo, kwiintambo ezide zekhebula (ezingaphezulu kweenyawo ze-3000 [914.4 ml), iindlela ezininzi zokukhanya zingabangela ukuphazamiseka kwesignali ekupheleni kokufumana, okubangelwa ukuhanjiswa kwedatha okungacacanga kunye nokungaphelelanga.
Uvavanyo kunye nokuqinisekisa intambo yefiber optic.
Ukuba uqhele ukungqina intambo yodidi lwesi-5, uya kumangaliswa ngendlela ekulula ngayo ukuqinisekisa intambo yefiber optic kuba awukhuselekanga kuphazamiseko lombane.Kufuneka ujonge imilinganiselo embalwa kuphela:
• I-Attenuation (okanye ilahleko ye-decibel) -Ilinganiswe nge-dB/km, oku kukuncipha kwamandla omqondiso njengoko ihamba ngentambo ye-fiber optic.• Ilahleko yokubuyisela-Ubungakanani bokukhanya obubonakalisiweyo ukusuka ekupheleni kude kwentambo ukuya kumthombo.Okukhona lisezantsi inani, kokukhona lingcono.Umzekelo, ufundo lwe -60 dB lungcono kuno -20 dB.
• I-graded refractive index-Ilinganisa ukuba kungakanani ukukhanya okuthunyelwa kwifiber.Oku kudla ngokulinganiswa kubude bobude obuyi-850 kunye ne-1300 yeenanometers.Xa kuthelekiswa namanye amaza okusebenza, ezi zintlu zimbini zivelisa eyona lahleko isezantsi yamandla engaphakathi.(QAPHELA Oku kuvumelekile kwifiber yemultimode kuphela.)
• Ukulibaziseka kosasazo-Eli lixesha elithatha umqondiso ukuhamba ukusuka kwindawo ukuya kwenye kwijelo lothumelo.
• I-time-domain reflectometry (TDR)-Ihambisa iipulses ze-high-frequency kwintambo ukuze ukwazi ukujonga ukubonakaliswa ecaleni kwentambo kwaye ukwahlula iimpazamo.
Baninzi abavavanyi befayibha optic kwimarike namhlanje.Abavavanyi be-fiber optic abasisiseko basebenza ngokukhanyisa isibane phantsi kwelinye icala lentambo.Kwelinye icala, kukho umamkeli olinganiswe kumandla omthombo wokukhanya.Ngolu vavanyo, unokulinganisa ukuba kungakanani ukukhanya okuya kwelinye icala lentambo.Ngokubanzi, aba bavavanyi bakunika iziphumo kwii-decibels (dB) ezilahlekileyo, onokuthi uzithelekise kuhlahlo lwabiwo-mali lwelahleko.Ukuba ilahleko elinganisiweyo ingaphantsi kwenani elibalwe ngebhajethi yakho yokulahlekelwa, ukufakela kwakho kulungile.
Abavavanyi abatsha befiber optic banoluhlu olubanzi lwezakhono.Banokuvavanya zombini iimpawu ze-850 kunye ne-1300-nm ngexesha elifanayo kwaye banokujonga i-Gable yakho ukuthobela imigangatho ethile.
Unokukhetha nini i-fiber optic.
Nangona intambo yefiber optic isabiza kakhulu kunezinye iindidi zentambo, iyathandwa kunxibelelwano lwedatha olukhawulezayo lwanamhlanje kuba iphelisa iingxaki zentambo ezijijekileyo, ezifana ne-close-end crosstalk (NEXT), interference electromagnetic (EIVII), kunye nokuphulwa kokhuseleko.Ukuba ufuna intambo yefayibha ungandwendwelawww.mireko-cable.com.
