Iintambo zamehlo zangaphantsi kwamanzi zikwazi njani ukukhukuliswa ngamanzi olwandle?

Iiintambo zamehloIinkwili zisesichengeni ngokugqithisileyo kukuhlwa kwamanzi olwandle ngenxa yokuntywiliselwa ixesha elide kumanzi olwandle axinaniswe kakhulu. Ukongeza, iimolekyuli ze-hydrogen ziya kusasazeka kwizinto zeglasi zefiber, eziya kubangela ukuba ukulahleka kwefiber kube kukhulu. Ke ngoko, intambo yokukhanya ekwi-submarine mayingathinteli kuphela i-hydrogen ekuvelisweni ngaphakathi, kodwa ikwathintele i-hydrogen ukuba ingangeni kwintambo yokukhanya ngaphandle. Okwangoku, ulwakhiwo lwentambo ye-submarine optical yi-helically ukusonga i-fiber optical emva kokugquma enye okanye ezimbini embindini, kunye nento yokuqinisa (eyenziwe ngocingo lwentsimbi) ijikelezwe kuyo.

Beka imephu ebonakalayo yolwandle, enengqiqo ngakumbi:

Intambo ye-submarine optical cable ifana nombhobho we-oyile, enyanisweni, umahluko omkhulu phakathi kwentambo ye-submarine optical cable kunye ne-terrestrial optical cable "yokukhusela izixhobo". Isizathu sokuba kutheni kufuneka iileya ezininzi kangaka zokhuseleko kungenxa yokuba imeko ephantsi kwamanzi apho iintambo zamehlo ezikwi-submarine optical cable zintsokothile kakhulu kwaye zingqwabalala. Eyokuqala kukugxwala kwamanzi olwandle Umaleko wepolymer wangaphandle wentambo yokubona inkwili kukuthintela ukusabela kwamanzi olwandle kunye nentambo yentsimbi eyomeleziweyo ukuvelisa ihydrogen. Nokuba umaleko wangaphandle udliwe ngokwenene, i-tubing yobhedu yangaphakathi, iparafini kunye ne-carbonic acid resin iya kuthintela i-hydrogen ekonakaliseni i-fiber optical. Ukungeniswa kwee-athomu ze-hydrogen kuya kukhokelela ekwandeni kokuthotywa kwe-fiber optic transmission. Ukongeza kwi-corrosion yamanzi olwandle, iintambo ze-optical zangaphantsi kwamanzi nazo ziphantsi koxinzelelo lwangaphantsi kwamanzi, iintlekele zendalo (iinyikima, iitsunami, njl.) kunye nezinto zabantu (imisebenzi yokuhlangula abalobi). Ngaphandle kokhuseleko oluphuculweyo lwezixhobo, iintambo zamehlo ezikwi-submarine azinakusebenza ngokuzinzileyo ixesha elide.
Nangona kunjalo, nangona ukhuseleko olungqongqo olunjalo, intambo ye-submarine optical ayinakusetyenziswa ngokusisigxina kwaye ubomi bayo benkonzo ngokuqhelekileyo buyiminyaka engama-25 kuphela.
