Okokuqala, i-optical fiber ayoyiki amanzi kuba ikhuselekile. Xa i-optical fiber ijikeleziswa kwintambo, kukho iimfuno ezimbini zokukhusela i-optical fiber: enye kukuba i-optical fiber iphantsi koxinzelelo oluncinci; enye kukuba i-optical fiber kufuneka ingangeni manzi. Umaleko ongaphandle wentambo ye-optical fiber yiplastiki, umaleko ongaphakathi yintsimbi, kwaye umaleko ongaphakathi yingubo ethintela amanzi evuvukalayo xa ibekwe emanzini. Umbindi wentambo ubotshelelwe nge-adhesive kunye ne-optical fibers.
Intambo ye-optical ineengcango ezine ezingangeni manzi, ezizezi: isiciko seplastiki, isiciko sesinyithi, umaleko ovimba amanzi, kunye namafutha okugcoba.
Umbuzo ke ngulo, ingaba i-fiber core iyoyika amanzi? Ayisiyoglasi nje, yintoni ingxaki ngamanzi?
Enyanisweni, uyoyika amanzi.
Usenokuzibuza ukuba kutheni iglasi ekwiitanki zeentlanzi nakwiifestile ekhayeni lakho ingoyiki amanzi kodwa ingangeni manzi, kwaye kutheni zonke zenziwe ngeglasi.
Kutheni i-fiber core isaba amanzi?
Ngokwesiqhelo kukholelwa ukuba i-fiber core ayichaphazeleki ngamanzi kuba iglasi inokumelana kakuhle namanzi. Nangona kunjalo, amanzi ayonakalisa kakhulu iintambo ze-optical. Ukuba amanzi angena kwintambo ye-optical, aya konakalisa intambo njengoko ibanda kwaye ikhula emanzini abandayo. Ke ngoko, iintambo ze-optical kufuneka zigqunywe nge-sealant ukuthintela ukungena komswakama.
Uvavanyo lubonisa ukuba ukungena komswakama ixesha elide kwintambo ye-optical kuya kwandisa ukulahleka kwefayibha ye-optical, ingakumbi kubude bobude be-1.55 pm.
Isizathu sokuba i-optical fiber yoyike amanzi kukuba i-optical fiber yenziwe yi-silicon-oxygen (SiO4) glass tetrahedra edibene kunye, njengoko kubonisiwe kuMfanekiso 1. Kwinethiwekhi ye-Si-O-Si, ii-athomu ze-oksijini zikhona ngendlela yeebhulorho ze-oksijini.
Nangona kunjalo, kwindawo enamanzi, emva kokuba umphezulu weglasi ufunxe umphunga wamanzi, kwenzeka i-hydrolysis reaction ecothayo, nto leyo ebangela ukuba i-silicon-oxygen bond iqhawuke kwinethiwekhi yokuqala—Si—O—Si—, kwaye i-oxygen bridge iba yi-oxygen engadibaniyo njengoko kubonisiwe kuMfanekiso 2, nto leyo ebangela ukuba kubekho imifantu kwiglasi, kwaye imifantu iyaqhubeka nokukhula.
Nokuba yiglasi yetanki yentlanzi, iglasi yefestile, okanye iglasi yefayibha optic, zonke zinokonakala emanzini. Umahluko kukuba iglasi yetanki yentlanzi kunye neglasi yefestile zityebile kakhulu, zinobukhulu obuyi-3 mm, 5 mm, kunye ne-10 mm. Nokuba ngumngxuma we-0.05 mm awuyi kuchaphazela amandla eglasi. Akukho tshintsho lubonakalayo.
I-optical fiber yahlukile. Ububanzi beglasi kwi-optical fiber yi-0.125 mm kuphela, ubukhulu bayo bulingana noboya bomntu. Ukuba kukho i-crack ye-0.05 mm, ububanzi be-optical fiber buya kuba yi-0.075 mm, nto leyo eyenza kube lula kakhulu ukuphula i-fiber. Ngaphezu koko, ukubonakala kweengcambu ze-OH kuya kwandisa amandla okufunxa ukukhanya kwe-optical fiber. Yingakho iglasi yetanki yentlanzi kunye neglasi yefestile zingachaphazeleki ngamanzi, ngelixa iglasi ye-optical fiber isengozini yokonakala ngamanzi.
Kwimeko enjalo, ukuba intambo ye-optical yonakele, isitywino sebhokisi ye-splice asilunganga kwaye i-fiber engenanto iyabonakala, ixesha lokuphila kwe-fiber ye-optical liya kufinyezwa kwaye i-fiber iya kuqhekeka ngokwemvelo ngenxa yamanzi.
Ngoko ke, ukuba intambo ye-fiber optic ifakwe kwimijelo yamanzi amdaka, ii-slices kufuneka ziqiniswe ngokufanelekileyo, kwaye ukuba intambo ye-fiber optic ngokwayo yonakele, kufuneka ilungiswe. Musa ukuvumela ingaphakathi lentambo ye-fiber optic lidibane namanzi.
