Pehea e pale aku ai nā uaea fiber optic ma lalo o ka wai i ka pala mai ka wai kai?

ʻO ka nā kaula ʻōpae He palupalu loa nā moku moana i ka pala o ka wai kai ma muli o ka hoʻoluʻu lōʻihi ʻana i loko o ka wai kai kiʻekiʻe. Eia kekahi, e pālahalaha nā molekole hydrogen i loko o ka mea aniani o ka fiber, e hoʻonui ana i ka nalowale o ka fiber. No laila, ʻaʻole pono nā kaula fiber optic submarine e pale wale i ka hydrogen mai ka hoʻokumu ʻana i loko akā mai ke komo ʻana i loko o ke kaula mai waho. I kēia manawa, ʻo ke ʻano o kahi kaula fiber optic submarine he wahī helically i ka fiber optical ma hope o hoʻokahi a ʻelua paha mau uhi ma ke kikowaena, me kahi mea hoʻoikaika (i hana ʻia me ke kaula kila) i wahī ʻia a puni.

E kau i kahi palapala ʻāina kino o ka moena kai, ʻoi aku ka maʻalahi o ka ʻike:

Ua like iki ke kaula fiber optic ma lalo o ka wai me ka paipu ʻaila; ʻo ka ʻoiaʻiʻo, ʻo ka ʻokoʻa nui ma waena o ke kaula fiber optic ma lalo o ka wai a me ke kaula fiber optic ma ka honua, ʻo ia kona "pale pale kaua." ʻO ke kumu e pono ai nā papa he nui o ka pale ʻana, no ka mea, he paʻakikī loa a ʻino ke kaiapuni ma lalo o ka wai o nā kaula fiber optic ma lalo o ka wai. ʻO ka hoʻoweliweli mua, ʻo ia ka pala o ka wai kai. Ua hoʻolālā ʻia ka papa polymer o waho o ke kaula fiber optic ma lalo o ka wai e pale i ka hopena ma waena o ka wai kai a me ke kaula kila i hoʻoikaika ʻia e hana i ka hydrogen. ʻOiai inā pala ka papa o waho, e pale aku ka paipu keleawe o loko, ka paraffin, a me ka resin carbonic acid i ka hydrogen mai ka hōʻino ʻana i ka fiber optical. ʻO ka komo ʻana o nā molekala hydrogen e alakaʻi i ka hoʻonui ʻia ʻana o ka hoʻoili fiber optic. Ma waho aʻe o ka pala o ka wai kai, ua pilikia pū nā kaula fiber optic ma lalo o ka wai i ke kaomi ma lalo o ka wai, nā pōʻino kūlohelohe (nā ʻōlaʻi, nā tsunami, a me nā mea ʻē aʻe), a me nā kumu kanaka (nā hana hoʻopakele lawaiʻa). Me ka ʻole o ka pale kaua i hoʻonui ʻia, ʻaʻole hiki i nā kaula fiber optic ma lalo o ka wai ke hana pono no nā wā lōʻihi.
Eia nō naʻe, me ia ʻano palekana koʻikoʻi, ʻaʻole hiki ke hoʻohana mau ʻia ke kaula fiber optic submarine a ʻo kona ola maʻamau he 25 mau makahiki wale nō.
