ʻO ka mea mua, ʻaʻole makaʻu ka fiber optical i ka wai no ka mea ua pale ʻia. Ke milo ʻia ka fiber optical i loko o ke kaula, aia ʻelua mau koi palekana no ka fiber optical: ʻo kekahi, ʻo ia ka emi ʻana o ke kaumaha o ka fiber optical; ʻo kekahi, pono e pale wai ka fiber optical. ʻO ka papa waho loa o ke kaula fiber optical he ʻūpā plastik, ʻo ka papa o loko he ʻūpā metala, a ʻo ka papa o loko he uhi pale wai e pehu ana i ka wā e hōʻike ʻia ai i ka wai. Hoʻopaʻa ʻia ke kikowaena o ke kaula me kahi sila a me nā fiber optical.
ʻEhā puka pale wai o ke kaula ʻōpae, ʻo ia hoʻi: ka uhi palaki, ka uhi metala, ka papa pale wai, a me ka ʻaila poni.
No laila, ʻo ka nīnau, makaʻu anei ka ʻiwi fiber i ka wai? ʻAʻole anei he aniani wale nō, he aha ka mea nui e pili ana i ka wai?
ʻO kaʻoiaʻiʻo, makaʻu ʻo ia i ka wai.
E noʻonoʻo paha ʻoe no ke aha i makaʻu ʻole ai ke aniani i loko o nā pahu iʻa a me nā puka makani i kou home i ka wai akā he pale wai, a no ke aha i hana ʻia ai lākou a pau i ke aniani.
No ke aha i makaʻu ai ka ʻiwi fiber i ka wai?
Manaʻo nui ʻia ʻaʻole i hoʻopilikia ʻia ka ʻiʻo o ka fiber e ka wai no ka mea he kūpaʻa wai maikaʻi loa ke aniani. Eia nō naʻe, he mea hōʻino loa ka wai i nā kaula optical. Inā komo ka wai i loko o ke kaula optical, e hōʻino ia i ka fiber i kona wā e paʻa ai a hoʻonui i ka wai anuanu. No laila, pono e uhi ʻia nā kaula optical me kahi sila e pale ai i ke komo ʻana o ka makū.
Ua hōʻike ʻia nā hoʻokolohua e hoʻonui ka komo ʻana o ka makū i loko o ke kaula optic i ka nalowale o ka fiber optical, ʻoiai ma ka nalu o 1.55 pm.
ʻO ke kumu e makaʻu ai ka fiber optical i ka wai, ʻo ia ka mea i hana ʻia ka fiber optical me ka silicon-oxygen (SiO4) glass tetrahedra i hoʻopili ʻia, e like me ka mea i hōʻike ʻia ma ke Kiʻi 1. Ma kahi pūnaewele Si-O-Si, aia nā ʻātoma oxygen ma ke ʻano o nā alahaka oxygen.
Eia nō naʻe, i loko o kahi ʻano me ka wai, ma hope o ka hoʻopili ʻana o ka ʻili aniani i ka mahu wai, hana ʻia kahi hopena hydrolysis lohi, e hopena ana i ka haki ʻana o ka pilina silicon-oxygen i loko o ka pūnaewele mua —Si—O—Si—, a lilo ke alahaka oxygen i oxygen i hoʻopili ʻole ʻia e like me ka mea i hōʻike ʻia ma ke Kiʻi 2, e hopena ana i nā māwae i ke aniani, a hoʻomau ka ulu ʻana o nā māwae.
Inā paha he aniani o ka pahu iʻa, he aniani puka makani, a he aniani fiber optic paha, ua maʻalahi lākou a pau i ka hōʻino ʻia e ka wai. ʻO ka ʻokoʻa, he mānoanoa loa ke aniani o ka pahu iʻa a me ke aniani puka makani, me nā mānoanoa he 3 mm, 5 mm, a me 10 mm. ʻOiai he māwae 0.05 mm, ʻaʻole ia e hoʻopilikia i ka ikaika o ke aniani. ʻAʻohe loli i ʻike ʻia.
He ʻokoʻa ke olonā ʻōpika. ʻO ke anawaena o ke aniani i loko o ke olonā ʻōpika he 0.125 mm wale nō, ʻo ia hoʻi ka mānoanoa e like me ka lauoho kanaka. Inā he māwae 0.05 mm, ʻo ke anawaena o ke olonā ʻōpika he 0.075 mm, e maʻalahi ai ka haki ʻana o ke olonā. Eia kekahi, ʻo ke ʻano o nā aʻa OH e hoʻonui pū i ka hiki omo mālamalama o ke olonā ʻōpika. ʻO ia ke kumu ʻaʻole i hoʻopilikia ʻia ke aniani o ka pahu iʻa a me ke aniani puka makani e ka wai, ʻoiai he maʻalahi ke aniani olonā ʻōpika i ka hōʻino ʻia e ka wai.
I kēia hihia, inā ua hōʻino ʻia ke kaula optical, ʻaʻole maikaʻi ka sila pahu splice a ua hōʻike ʻia ka fiber ʻōlohelohe, e pōkole ke ola o ka fiber optical a e haki maoli ka fiber ma muli o ka wai.
No laila, inā hoʻokomo ʻia ke kaula fiber optic i loko o nā ʻauwai, pono e hoʻopaʻa pono ʻia nā mea hoʻohui, a inā ua hōʻino ʻia ke kaula fiber optic ponoʻī, pono e hoʻoponopono ʻia. Mai ʻae i ka wai e hoʻopili i loko o ke kaula fiber optic.
