Okokuqala, intambo ye-optical ayiwoyiki amanzi ngenxa yokuba ikhuselwe. Xa intambo ye-optical iguqulwa ibe yintambo, kukho iimfuno ezimbini zokukhusela i-fiber optical: enye kukuba i-fiber optical ayigxininisi; enye kukuba i-fiber optical kufuneka ingangeni manzi. Uluhlu olungaphandle lwentambo ye-optical sheath yeplastiki, ingaphakathi liyintsimbi yesinyithi, kwaye ingaphakathi liyi-block blocking layer yamanzi evuvukala ngamanzi, kwaye ingundoqo yekhebula ifakwe kwi-ointment kunye ne-optical fibers.
Intambo yamehlo ineengcango ezine ezingangeni manzi, ezizezi: isigqubuthelo seplastiki, isigqubuthelo sesinyithi, umaleko othintela amanzi kunye ne-ointment.
Ke umbuzo ngulo, ingaba i-fiber core yoyika amanzi? Ayiyo glass nje, woyika ntoni amanzi?
Phofu uyawoyika amanzi.
Unokucinga ukuba kutheni iglasi yetanki yeentlanzi kunye neglasi yefestile ekhaya ingesabi amanzi kodwa ingenamanzi, kwaye kutheni zonke ziyiglasi?
Kutheni i-fiber core yoyika amanzi?
Ngokuqhelekileyo kukholelwa ukuba i-fiber core ayiwoyiki amanzi, kuba iglasi inokunamathela kakuhle kwamanzi. Kodwa eneneni, amanzi ayingozi kakhulu kwiintambo zamehlo. Ukuba amanzi angena kwintambo ye-optical, iya kulimaza i-fiber optical xa iqhwala kwaye iyanda emanzini abandayo, ngoko ke ikhebula le-optical kufuneka lizaliswe nge-ointment ukukhusela umswakama ukuba ungangeni.
Iimvavanyo zibonisa ukuba ukungena komswakama ixesha elide kwikhebula le-optical kuya kwandisa ilahleko yefiber optical, ngakumbi kwi-1.55 pm wavelength.
Isizathu sokuba i-fiber optical isaba amanzi kukuba i-fiber optical yenziwe ngeglasi (SiO4) i-silicon-oxygen tetrahedra edibeneyo, njengoko kuboniswe kuMzobo 1. Kwinethiwekhi ye-Si-O-Si, ii-athomu ze-oksijini zikhona ngendlela ye-oxygen. iibhulorho.
Nangona kunjalo, kwindawo yamanzi, emva kokuba i-glass surface ibhengeze umphunga wamanzi, ukusabela okucothayo kwe-hydrolysis kwenzeka, okubangelwa ukuphulwa kwebhondi ye-silicon-oxygen kwi-original-Si-O-network Ewe-, kunye ne-oksijini edibeneyo iyancipha ioksijini njengoko kuboniswe kuMfanekiso 2, okubangela ukuqhekeka kweglasi, kwaye iintanda ziyaqhubeka zikhula.
Nokuba yiglasi yetanki yentlanzi, iglasi yefestile okanye iglasi yefiber optic, wonke umntu uyawoyika amanzi. Umahluko kukuba iglasi yetanki yeentlanzi kunye neglasi yefestile zinzima kakhulu, ezinobunzima be-3mm, 5mm kunye ne-10mm. Nokuba kukho ukuqhekeka kwe-0.05mm, akuyi kuchaphazela amandla eglasi Akukho tshintsho kwiliso lenyama.
I-glass ye-fiber optical yahlukile i-diameter ye-fiber optical kuphela i-0.125mm, ebunzima njengeenwele ukuba kukho ukuqhekeka kwe-0.05mm, ububanzi be-fiber optical iya kuba yi-0.075mm, ngoko i-fiber yi-fiber. Kulula kakhulu ukuphuka, ukongeza, ukubonakala kweengcambu ze-OH kuya kwandisa ukulahleka kokukhanya kwe-fiber optical. Yiyo loo nto iglasi yetanki yeentlanzi kunye neglasi yefestile ayiwoyiki amanzi, ngelixa iglasi yefiber optic isoyika amanzi.
Kule meko, ukuba intambo ye-optical yonakalisiwe, ukutywinwa kwebhokisi le-junction akulungile kwaye i-fiber engenanto ibonakaliswe, ubomi benkonzo ye-fiber optical buya kufinyezwa kwaye i-fiber iya kuphuka ngokwemvelo ngenxa yamanzi.
Ngoko ke, ukuba i-fiber optical yakhiwe kwi-sewers, amajoyina kufuneka aphathwe kakuhle, kwaye ukuba i-fiber optical ngokwayo yonakaliswe, kufuneka ilungiswe. Musa ukuvumela umphakathi wefiber optical udibane namanzi.
