Umhlahlandlela Oyisisekelo Wokukhetha Ikhebula le-Fiber Optics

Nakuba Ikhebula le-Fiber OpticAma-s asetshenziswa kabanzi kwezobunjiniyela bezokuxhumana, abantu abaningi abanalo ulwazi olujulile ngokukhetha kwabo. Sivame ukuthola imibuzo evela kumakhasimende ku-inthanethi noma ngocingo mayelana nendlela yokukhetha okulungile. Ikhebula le-Fiber OpticNamuhla, sizochaza ukuthi ungakhetha kanjani Ikhebula le-Fiber Optic imikhiqizo ngokwemibono yesakhiwo, izinto zokwakha, kanye nezinqubo zokukhiqiza.

I. Ukukhetha Ikhebula le-Fiber Optics Ngokusekelwe Ezintweni Ezisetshenziswayo: Izinto ezisetshenziswayo kanye nezinqubo zokukhiqiza Ikhebula le-Fiber OpticAma-s abalulekile empilweni yawo. Inqubo yokukhiqiza iyisici esibalulekile esithinta ikhwalithi yekhebula. Imikhiqizo enezinqubo ezizinzile kanye nekhwalithi enhle kakhulu ngokuvamile inokulahlekelwa okuncane kwefayibha kuyo yonke inqubo yokukhiqiza; ≤0.01dB/km iyisibonakaliso esiyisisekelo somkhiqizi. Ikhebula le-Fiber Optic izinga lokukhiqiza. Izinto eziyinhloko ezisetshenziswa ezintanjeni ze-fiber optical zifaka: ama-fiber cores, i-fiber optic grease, izinto zokubopha, kanye ne-PBT (polybutylene terephthalate). Ngayinye inezidingo zekhwalithi ezahlukene. Ama-fiber cores adinga amandla aphezulu okuphatha, isilinganiso esiphezulu sesignali kuya kumsindo, izinga eliphansi lamaphutha e-bit, isikhala eside se-amplifier, kanye nomthamo ophezulu wokuthwala ulwazi. I-fiber optic grease ibhekisela kumafutha agcwalisa i-fiber optic tube; umsebenzi wayo ukabili: okokuqala, ukuvimbela umswakama emoyeni ukuthi ungonakalisi i-fiber; kanti okwesibili, ukusebenza njengomcamelo, ukuvimba i-fiber ekudlidlizeni noma ekushayweni.

II. Ukukhetha Amakhebula E-Optical Fiber Ngokusekelwe Ekubalweni Okuyinhloko: Amakhebula e-optical amamodeli ahlukene angahlukaniswa ngenani eliyinhloko ngezinhlobo eziningana, kufaka phakathi ithubhu elikhululekile eliphakathi, i-stranded, i-skeleton, kanye neribhoni. Izinhlelo zokusebenza ezahlukene zidinga izakhiwo ezahlukene, futhi abasebenzisi bangacacisa izidingo zabo ngokusekelwe ezimweni zomugqa. Ngokuvamile, amakhebula anama-cores angu-12 noma ngaphansi asebenzisa uhlobo lwethubhu elikhululekile eliphakathi. Uhlobo lwethubhu elikhululekile eliphakathi lulula ukulwenza futhi lubiza kancane, okwenza luncintisane ekufakweni okuphezulu noma kumanethiwekhi e-trunk ngokuvikelwa okuhle kwe-duct. Amakhebula e-optical astranded asebenzisa imicu yensimbi ebekwe phakathi noma izintambo zensimbi eyodwa ukuze kuqiniswe, kusetshenziswa i-SZ splicing ukwakha ikhebula, futhi angaba nama-cores afinyelela ku-144. Izinzuzo zalo zifaka phakathi ukuvimbela amanzi, ukumelana namandla aqinile okunamathela, kanye nokucindezela okuqinile kwe-lateral. Ingagqitshwa ngqo ngaphansi komhlaba. Kulula futhi ukuwahlukanisa; okungukuthi, lapho imicu ngayinye kukhebula idinga ukusetshenziswa ngokwehlukana, akudingekile ukusika ikhebula lonke, kodwa imicu ezohlukaniswa kuphela enganqunywa. Lokhu kuwusizo kumanethiwekhi okuxhumana kwedatha kanye nokwengeza ama-optical node endleleni yamanethiwekhi ethelevishini yekhebula. Amakhebula eribhoni angaba nezinkulungwane zama-core. Zenziwa ngokuhlela imicu ye-optical engu-4-12 emigqeni ukuze yakheke I-Ribbon Fiber amayunithi, bese sihlela amayunithi amaningi eribhoni ngendlela ethile ukuze sakhe ikhebula. Kumakhebula e-optical asezingeni lenethiwekhi, ngokuvamile sikhetha uhlobo lweshubhu elihlanganisiwe noma uhlobo olunezingqimba.

III. Ukukhetha Ikhebula le-Fiber OpticNgokusho Kwesicelo: Izintambo ze-optical zingahlukaniswa ngokwesicelo sazo, njengezintambo zasemoyeni, izintambo ezingcwatshwe ngqo, izintambo ze-duct, izintambo zasemanzini, kanye nezintambo ezingezona ezensimbi. Izintambo ze-optical zasemoyeni zidinga amandla aphezulu kanye ne-coefficient ephansi yokushisa; izintambo ze-optical ezingcwatshwe zidinga ukumelana okuhle nokungcwatshwa, ingcindezi, umswakama, kanye nomswakama, kanye nokumelana nokugqwala kwamakhemikhali; izintambo ze-optical zasemanzini kanye nezintambo zasemanzini zidinga ukumelana okuhle nokucindezelwa kwamanzi, amandla okuthamba, kanye nokuvimbela amanzi; izintambo ze-optical ezingezona ezensimbi zingabekwa eceleni kwemigqa ye-voltage ephezulu, zidinga ukufudumala okuhle futhi, yize zingenayo i-core yokuqinisa insimbi, zisadinga amandla athile okuthamba. Ngakho-ke, lapho bethenga izintambo ze-optical, abasebenzisi kufanele bakhethe ngokwesicelo esihlosiwe futhi benze izidingo kumenzi ukuqinisekisa ukusebenza okuzinzile nokuthembekile.

Ekuphetheni, ukukhethwa kwezintambo ezibonakalayo akukwazi ukususelwa nje entengoni ngayinye. Kunalokho, kufanele kusekelwe ekucabangeni okubanzi kwesakhiwo sekhebula, izinto zokusetshenziswa, inqubo yokukhiqiza, kanye nemininingwane yobuchwepheshe. Akufanele sikhethe umkhiqizo oshibhile nje kuphela. Kunezinto eziningi okudingeka zicatshangelwe, hhayi nje kuphela isikhathi saso senkonzo kodwa futhi nezindinganiso zokusebenza zephrojekthi iyonke—ukukubeka ngokungathi sína, ukuzinza nokuphepha kwenethiwekhi yokuxhumana kazwelonke.
