Iyini ikhebula le-Outdoor Optical?
Ikhebula le-optical langaphandle liwuhlobo lwekhebula le-fiber optical elisetshenziselwa ukudlulisa ukuxhumana. Ifaka ungqimba olwengeziwe oluyisivikelo olwaziwa ngokuthi izikhali noma i-metal sheathing, ehlinzeka ngokuvikeleka ngokomzimba emiculweni yokubona, okuyenza iqine futhi ikwazi ukusebenza ezimeni ezinzima zemvelo.
I. Izingxenye Ezibalulekile
Izintambo ezibonakalayo zangaphandle ngokuvamile zinemicu engenalutho, ishubhu elixegayo, izinto ezivimba amanzi, izakhi eziqinisayo, nomgodla wangaphandle. Ziza ngezakhiwo ezihlukahlukene ezifana ne-central tube design, i-layer stranding, kanye nesakhiwo samathambo.
Imicu engenalutho ibhekisela emiculweni yasekuqaleni enobubanzi obungama-micrometer angu-250. Ngokuvamile zihlanganisa isendlalelo esiyinhloko, isendlalelo sokuvala, kanye nosendlalelo sokumboza. Izinhlobo ezihlukene zemicu engenalutho inosayizi abahlukene bongqimba obuyinhloko. Isibonelo, imicu ye-OS2 yemodi eyodwa ngokuvamile ingama-micrometer angu-9, kuyilapho imicu ye-multimode i-OM2/OM3/OM4/OM5 ingama-micrometer angu-50, kanti imicu ye-multimode OM1 ingama-micrometer angu-62.5. Imicu engenalutho ivamise ukufakwa amakhodi ngombala ukuze kuhlukaniseke phakathi kwama-multi-core fibers.
Amashubhu axegayo ngokuvamile enziwa ngobunjiniyela bepulasitiki obuqinile obuphezulu be-PBT futhi asetshenziselwa ukufaka imicu engenalutho. Zinikeza isivikelo futhi zigcwaliswa ngejeli yokuvimbela amanzi ukuvimbela ukungena kwamanzi okungalimaza imicu. Ijeli futhi isebenza njengesivimbeli ukuvikela ukulimala kwefayibha emithelela. Inqubo yokukhiqiza amashubhu axegayo ibalulekile ukuze kuqinisekiswe ubude obudlulele be-fiber.
Izinto ezivimbela amanzi zihlanganisa amafutha avimbela amanzi ekhebula, intambo yokuvimba amanzi, noma impushana evimba amanzi. Ukuze kuthuthukiswe ikhono lilonke lekhebula lokuvimbela amanzi, indlela evamile iwukusebenzisa amafutha avimba amanzi.
Izinto eziqinisayo ziza ngezinhlobo zensimbi nezingezona ezensimbi. Ezensimbi ngokuvamile zenziwe ngezintambo zensimbi ze-phosphated, amateyipu e-aluminium, noma amateyipu ensimbi. Izinto ezingezona ezensimbi ngokuyinhloko zenziwe ngezinto ze-FRP. Kungakhathalekile ukuthi iyiphi into esetshenzisiwe, lezi zakhi kumele zinikeze amandla adingekayo ukuze kuhlangatshezwane nezidingo ezijwayelekile, okuhlanganisa ukumelana nokushuba, ukugoba, umthelela, nokusonteka.
Amashethi angaphandle kufanele acabangele indawo esetshenziswayo, okuhlanganisa ukuvikela amanzi, ukumelana ne-UV, nokumelana nesimo sezulu. Ngakho-ke, izinto ezimnyama ze-PE zivame ukusetshenziswa, njengoba izakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali ziqinisekisa ukufaneleka kokufakwa kwangaphandle.
II. Izici kanye nezicelo
Ukumelana Nomlilo: Ngenxa yokuba khona kweshethi yensimbi, izintambo ezibonakalayo zangaphandle zibonisa ukumelana nomlilo okuhle kakhulu. Izinto zensimbi zingakwazi ukumelana namazinga okushisa aphezulu futhi zihlukanise ngempumelelo amalangabi, zinciphise umthelela womlilo ezinhlelweni zokuxhumana.
Ukudluliswa Kwebanga Elide: Ngokuvikeleka okuthuthukisiwe ngokomzimba kanye nokumelana nokuphazamiseka, amakhebuli okubona angaphandle angasekela ukudluliswa kwesignali yebanga elide. Lokhu kubenza basebenziseke kakhulu ezimeni ezidinga ukudluliswa kwedatha okubanzi.
Ukuvikeleka Okuphezulu: Izintambo ezibonakalayo zangaphandle zingamelana nokuhlaselwa ngokomzimba nokulimala kwangaphandle. Ngakho-ke, asetshenziswa kabanzi ezindaweni ezinezidingo zokuphepha eziphezulu zenethiwekhi, njengezisekelo zamasosha nezikhungo zikahulumeni, ukuqinisekisa ukuphepha nokuthembeka kwenethiwekhi.
III. Izinzuzo phezu Amakhebula Okukhanya Avamile
Ukuvikelwa Okuqinile Komzimba: Igobolondo lensimbi lezintambo zangaphandle livikela kahle i-fiber core ekulimaleni kwangaphandle ngokomzimba. Ivimbela ikhebuli ukuthi ingachotshozwa, yelulwe, noma isikwe, inikeze ukuqina nokuzinza okungcono.
Ukumelana Nokuphazamiseka Okuphezulu: I-sheath yensimbi iphinde isebenze njengesivikelo sika-electromagnetic, ivimbela ukuphazamiseka kwe-electromagnetic kwangaphandle ukuthi kuthikameze ukudluliswa kwesignali ye-optical kanye nokuthuthukisa ukumelana nokuphazamiseka.
Ukuzivumelanisa Nezindawo Eziqinile: Izintambo ezibonakalayo zangaphandle zingasetshenziswa ezindaweni ezihlukahlukene ezinokhahlo, okuhlanganisa amazinga okushisa aphezulu naphansi, umswakama, nokugqwala. Lokhu kubenza bafaneleke ikakhulukazi ukuxhunywa kwangaphandle, ukuxhumana ngaphansi kwamanzi, izimboni, kanye nezicelo zezempi.
Ukuvikela Okungeziwe Komshini: Igobolondo lensimbi lingamelana nokucindezela okukhulu komshini kanye nokushuba, ukuvikela imicu emandleni angaphandle kanye nokunciphisa ingozi yokulimala kwekhebula.
Kubalulekile ukuqaphela ukuthi izintambo ezibonakalayo zangaphandle zingase zibe nezindleko eziphakeme kanye nobunzima bokufaka uma kuqhathaniswa nezintambo ezivamile. Ngenxa yobukhona be-metal sheath, izintambo zangaphandle zikhulu kakhulu futhi aziguquguquki kancane, okwenza ukukhetha kohlobo lwekhebula olufanele kubaluleke kakhulu ezimeni ezithile.
Ngokuvikeleka kwayo okuqinile ngokomzimba, ukumelana nokuphazamiseka, kanye nokuvumelana nezimo eziyinselele, izintambo ezibonakalayo zangaphandle seziphenduke inketho ekhethwayo yezinhlelo zokusebenza eziningi ezibucayi, ezihlinzeka ngokusekela okubalulekile kokudluliselwa kokuxhumana okuthembekile.
