Chingwe cha sitima yapamadzi

Zingwe za fiber optic za pansi pa nyanja ndi njira yothandiza yolumikizirana ndikutumiza chidziwitso padziko lonse lapansi. Zingwe za fiber optic zapadziko lonse lapansi zimagwira ntchito yofunika kwambiri pakulankhulana kwapadziko lonse lapansi. Chifukwa cha kukula mwachangu kwa mafakitale monga cloud computing, big data, ndi Internet of Things, kugawana deta padziko lonse lapansi ndi kulumikizana kuli pafupi. Kufunika kwa kulumikizana padziko lonse lapansi komanso kulumikizana kwa kulumikizana ndi maukonde kukuyendetsa kufunikira kwa zingwe za fiber optic zapadziko lonse lapansi. Zingwe za fiber optic za pansi pa nyanja zakhala njira yayikulu ya zingwe za fiber optic zapadziko lonse lapansi chifukwa cha khalidwe lawo lapamwamba, kutanthauzira kwawo kwakukulu, mphamvu yayikulu, magwiridwe antchito olimba achitetezo, komanso mtengo wotsika. Malinga ndi TeleGeography, zopitilira 95% za kutumiza deta padziko lonse lapansi zikuchitika kudzera mu zingwe za pansi pa nyanja. Zingwe za fiber optic za pansi pa nyanja ndi njira yaukadaulo yomwe imaposa kulumikizana kwa satelayiti pakugwiritsa ntchito mphamvu yotumizira komanso kugwiritsa ntchito ndalama moyenera, zomwe zimapangitsa kuti zikhale ukadaulo wofunikira kwambiri wolumikizirana kudutsa dziko lonse lapansi masiku ano.

Pakati pa chingwe cha pansi pamadzi chimapangidwa ndi ulusi wowala wonyezimira kwambiri, womwe umatsogolera kuwala panjira ya ulusi kudzera mu kuwala kwamkati. Pakupanga zingwe za pansi pamadzi, ulusi wowala choyamba umayikidwa mu gelatinous compound yomwe imateteza chingwecho kuti chisawonongeke, ngakhale chikakhudzana ndi madzi a m'nyanja. Kenako chingwe cha ulusi wowala chimayikidwa mu chubu chachitsulo kuti chisasweke chifukwa cha kuthamanga kwa madzi. Kenako, chimakulungidwa mu waya wachitsulo wolimba kwambiri, chimayikidwa mu chubu chamkuwa, ndipo pamapeto pake chimakutidwa ndi polyethylene yoteteza.
