Okokuqala, i-optical fiber ayiwesabi amanzi ngoba ivikelwe. Uma i-optical fiber iphothwa ibe yikhebula, kunezidingo ezimbili zokuvikela i-optical fiber: eyodwa ukuthi i-optical fiber ingaphansi kokucindezeleka okuncane; enye ukuthi i-optical fiber kumele ingangeni manzi. Ingqimba engaphandle yekhebula le-optical fiber iyisigxobo sepulasitiki, ungqimba olungaphakathi luyisigxobo sensimbi, kanti ungqimba olungaphakathi luyisimbozo esivimba amanzi esivuvukalayo uma sichayeka emanzini. Ingaphakathi lekhebula liboshwe nge-sealant kanye nemicu ye-optical.
Ikhebula le-optical lineminyango emine engangeni manzi, okuyi: isembozo sepulasitiki, isembozo sensimbi, isendlalelo esivimba amanzi, kanye namafutha okugcoba.
Ngakho-ke umbuzo uwukuthi, ingabe i-fiber core iyawesaba amanzi? Akuyona nje ingilazi, yini inkinga enkulu ngamanzi?
Eqinisweni, uyawesaba amanzi.
Ungase uzibuze ukuthi kungani ingilazi esematangini ezinhlanzi nasemafasiteleni ekhaya lakho ingawesabi amanzi kodwa ingangeni manzi, nokuthi kungani yonke yenziwe ngengilazi.
Kungani i-fiber core yesaba amanzi?
Ngokuvamile kukholelwa ukuthi i-fiber core ayithinteki ngamanzi ngoba ingilazi inokumelana okuhle kakhulu namanzi. Kodwa-ke, amanzi empeleni alimaza kakhulu izintambo ze-optical. Uma amanzi engena ngaphakathi kwentambo ye-optical, izolimaza intambo njengoba iqina futhi ikhula emanzini abandayo. Ngakho-ke, izintambo ze-optical kufanele zimbozwe nge-sealant ukuvimbela umswakama ukungena.
Ukuhlolwa kubonisa ukuthi ukungena komswakama isikhathi eside kukhebula le-optical kuzokwandisa ukulahleka kwe-optical fiber, ikakhulukazi ku-wavelength engu-1.55 ntambama.
Isizathu sokuthi i-optical fiber yesabe amanzi ukuthi i-optical fiber yakhiwe yi-silicon-oxygen (SiO4) glass tetrahedra exhunywe ndawonye, njengoba kuboniswe kuMfanekiso 1. Kunethiwekhi ye-Si-O-Si, ama-athomu e-oxygen akhona ngesimo samabhuloho e-oxygen.
Kodwa-ke, endaweni enamanzi, ngemva kokuba ubuso bengilazi bumunce umhwamuko wamanzi, kwenzeka ukusabela kwe-hydrolysis okuhamba kancane, okuholela ekuphukeni kwesibopho se-silicon-oxygen kunethiwekhi yokuqala — i-Si—O— i-Si—, futhi ibhuloho le-oxygen liba yi-oxygen engaxhumani njengoba kuboniswe kuMfanekiso 2, okuholela ekuqhekekeni engilazini, futhi imifantu iyaqhubeka nokukhula.
Kungakhathaliseki ukuthi ingilazi yethangi lenhlanzi, ingilazi yefasitela, noma ingilazi ye-fiber optic, konke lokhu kungalimaza amanzi. Umehluko ukuthi ingilazi yethangi lenhlanzi kanye nengilazi yefasitela kukhulu kakhulu, kunobukhulu obungu-3 mm, 5 mm, kanye no-10 mm. Ngisho nokuqhekeka okungu-0.05 mm ngeke kuthinte amandla engilazi. Azikho izinguquko ezibonakalayo.
I-optical fiber ihlukile. Ububanzi bengilazi ku-optical fiber bungu-0.125 mm kuphela, obuwugqinsi njengoboya bomuntu. Uma kukhona ukuqhekeka okungu-0.05 mm, ububanzi be-optical fiber buzoba ngu-0.075 mm, okwenza kube lula kakhulu ukuphuka kwe-fiber. Ngaphezu kwalokho, ukubonakala kwezimpande ze-OH kuzokwandisa amandla okumunca ukukhanya kwe-optical fiber. Yingakho ingilazi yethangi lezinhlanzi kanye nengilazi yefasitela kungathinteki ngamanzi, kuyilapho ingilazi ye-optical fiber isengozini yokulimala kwamanzi.
Kulesi simo, uma ikhebula le-optical lonakele, uphawu lwebhokisi le-splice alulungile futhi i-fiber engenalutho iveziwe, isikhathi sokuphila se-fiber ye-optical sizofinyezwa futhi i-fiber izophuka ngokwemvelo ngenxa yamanzi.
Ngakho-ke, uma ikhebula le-fiber optic lifakwe ezindaweni zokulahla indle, ama-slices kumele aqiniswe kahle, futhi uma ikhebula le-fiber optic ngokwalo lonakele, kumele lilungiswe. Ungavumeli ingaphakathi lekhebula le-fiber optic lithintane namanzi.
