I ka hoʻolālā ʻana o ke kaula fiber optical (OFC), he mea koʻikoʻi ke koho ʻana i nā mea maka kūpono. ʻO nā ʻano hana like ʻole—e like me ke anuanu loa, nā mahana kiʻekiʻe, ka makū, ke kau ʻana ma waho, ke kūlou mau ʻana, a i ʻole ka neʻe pinepine ʻana—e kau ana i nā koi like ʻole ma nā mea kaula optical. Maanei, hōʻuluʻulu mākou i kekahi mau mea koʻikoʻi i hoʻohana pinepine ʻia i ka ʻoihana, e nānā ana i kā lākou mau ʻano hana a me nā noi kūpono e kōkua i ka hoʻonui ʻana i kāu hoʻolālā kaula fiber optical a me ke koho ʻana i nā mea.
1. PBT (Polybutylene Terephthalate) - ʻO ka mea maʻamau no nā paipu wehe
PBTʻo ia ka mea i hoʻohana nui ʻia no nā paipu wehe i nā kaula fiber optical. ʻO nā plastics kaula maʻamau e lilo i mea palupalu i nā mahana haʻahaʻa a palupalu i nā mahana kiʻekiʻe. ʻO ka PBT i hoʻololi ʻia, no ka laʻana me nā ʻāpana kaulahao palupalu, hoʻomaikaʻi nui i ke kūpaʻa hopena haʻahaʻa a hiki ke hoʻokō i nā koi a hiki i -40°C. Eia kekahi, hāʻawi ʻo PBT i ka paʻakikī maikaʻi loa a me ke kūpaʻa dimensional i nā mahana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka palekana hilinaʻi no nā fibers ma lalo o ke kaumaha wela. ʻO kāna hana kaulike, ke kumukūʻai kūpono, a me ka versatility e lilo ia i koho maʻamau no nā kaula kamaʻilio waho, nā kaula lōʻihi, a me nā ʻano kaula ADSS.
2. PP (Polypropylene) — ʻOi aku ka paʻakikī o ka mahana haʻahaʻa a me ke kū'ē ʻana i ka hydrolysis
Ua loaʻa ka nānā ʻana iā PP i nā mea kaula optical ma muli o kona paʻakikī haʻahaʻa maikaʻi loa, e pale ana i ka haki ʻana i nā kūlana anuanu loa. ʻOi aku ka maikaʻi o kona kūpaʻa hydrolysis ma mua o PBT, e kūpono ai no nā wahi pulu a wai paha. Eia nō naʻe, ʻoi aku ka haʻahaʻa o ka modulus a me ka paʻakikī o PP i hoʻohālikelike ʻia me PBT, no laila pono e noʻonoʻo kona hoʻohana ʻana i ke ʻano o ke kaula kikoʻī. No ka laʻana, ʻo nā kaula māmā, nā kaula hybrid i loko a i waho, a i ʻole nā hale paipu wehe e koi ana i ka maʻalahi kiʻekiʻe e koho iā PP ma ke ʻano he koho ʻē aʻe.
3. LSZH (Low Smoke Zero Halogen) — ʻO ka Mainstream Eco-Friendly Cable Jacket Material
LSZHʻo ia ka mea ʻaʻahu kaula aloha kaiapuni i hoʻohana nui ʻia. ʻO nā ʻano LSZH kiʻekiʻe, i hoʻokō ʻia ma o nā ʻōnaehana polymer kūikawā a me nā ʻenehana hoʻopihapiha, hiki ke hoʻokō i nā koi hopena haʻahaʻa -40°C a hoʻomau i ka hoʻohana lōʻihi ma 85°C. I ka hihia o ke ahi, hoʻokuʻu ʻo LSZH i ka uahi haʻahaʻa a ʻaʻohe kinoea halogen, e hoʻonui nui ana i ka palekana no nā kaula o loko, nā kaula kikowaena ʻikepili, a me nā uwea hale lehulehu. Hāʻawi pū ia i ke kūpaʻa maikaʻi loa i ka haki ʻana o ke kaiapuni a me ka pala kemika, e lilo ia i koho versatile no nā ʻaʻahu kaula o loko a me waho.
4. TPU (Thermoplastic Polyurethane) - ʻO ke "Mōʻī" o ka maʻalahi o ka mahana haʻahaʻa a me ke kū'ē ʻana i ka abrasion
Ua kaulana ʻo TPU no kona palupalu a me ka paʻakikī ma lalo o nā mahana haʻahaʻa loa. ʻAʻole e like me ka PVC, kūpaʻa loa ʻo TPU a ʻaʻole e māwae. Loaʻa iā ia ke kūpaʻa koʻikoʻi i ka abrasion, ka ʻaila, a me ka haehae, e kūpono ai no ka hoʻoneʻe ʻana i nā kaula, me nā kaula kaulahao kauō, nā kaula kaʻa, nā kaula mining, nā kaula robotic, a me nā noi automation ʻoihana. E hoʻomaopopo he hilinaʻi ke kūpaʻa wela kiʻekiʻe a me ka hydrolysis o TPU i ka papa kikoʻī, no laila he mea koʻikoʻi ke koho ʻana i nā ʻano hana kiʻekiʻe.
5. PVC (Polyvinyl Chloride) — Koho ʻAʻahu Uea Kūpono me ke Kumukūʻai me nā Palena Haʻahaʻa Haʻahaʻa
Ke hoʻohana mau nei ʻo PVC no kekahi mau kaula optical ma muli o kona kumukūʻai haʻahaʻa a me ka maʻalahi o ke kaʻina hana. Eia nō naʻe, paʻakikī ka PVC maʻamau a hiki ke haki ma lalo o -10°C, e lilo ia i mea kūpono ʻole no nā kūlana anuanu loa. Hiki i ka PVC haʻahaʻa wela a i ʻole ke kūpaʻa anu ke hoʻohaʻahaʻa i ka mahana hoʻololi aniani ma o nā plasticizers, akā hiki i kēia ke hoʻopilikia i ka ikaika mechanical a me ke kūpaʻa ʻelemakule. No laila, ʻoi aku ka maikaʻi o ka PVC no nā papahana koʻikoʻi i ke kumukūʻai ma nā wahi paʻa, e like me nā hoʻonohonoho kūloko maʻamau a i ʻole nā hoʻonohonoho kaula manawa pōkole.
6. TPV (Thermoplastic Vulcanizate) — Hoʻohui i ka Rubber Elasticity a me ka Plastic Processability
Hoʻohui ʻo TPV i ka elasticity o ka rubber me ka hiki ke hana ʻia o ka plastic. Hāʻawi ia i ke kūpaʻa maikaʻi loa i ke kiʻekiʻe a me ka haʻahaʻa o ka mahana, a me ke kūpaʻa maikaʻi loa i ka wā a me ke kūpaʻa ozone. ʻO ka maʻalahi a me ke kūpaʻa o TPV e kūpono ia no nā kaula optical waho, nā uwea kaʻa, a me nā kaula maʻalahi. Ma ke ʻano he mea hana, hoʻohālikelike ʻo TPV i nā ʻano o TPU a me PVC, e hāʻawi ana i ka maʻalahi o ke kūkulu ʻana a me ke kūpaʻa o ke kaiapuni.
7. XLPE (Crosslinked Polyethylene) - Mea Hoʻokaʻawale Mahana Kiʻekiʻe no nā Uea Optical a me nā Uea Mana
XLPE, ma o ke crosslinking, hoʻonui i ke kūpaʻa wela a hiki ke hana mau ma luna o 90°C. Hāʻawi pū ia i ka ikaika mechanical kiʻekiʻe a me ke kūpaʻa i ke kaumaha. ʻOiai ʻoi aku ka hoʻohana ʻia ʻana o XLPE no ka insulation uwea mana (e laʻa, 1kV–35kV), hoʻohana ʻia i kekahi manawa i nā kaula optical no ka hoʻoikaika a i ʻole nā hana wela kiʻekiʻe. ʻO kona mau waiwai thermal a me mechanical e kūpono ia no nā kaula optical kūikawā i nā wahi ʻino.
Ke koho ʻana i nā mea ʻaʻahu kaula optical - He mea nui nā hiʻohiʻona noi
ʻO ke koho ʻana i nā mea kaula optical kūpono e pono ai ma mua o ka nānā ʻana i ka ʻikepili loea; pono nō hoʻi e noʻonoʻo i nā hiʻohiʻona noi maoli:
Ka Hoʻouka Paʻa (waho, duct, aerial): LSZH, TPV, XLPE
Nā noi hoʻoneʻe (kaulahao kauō, robotics, nā kaʻa, mining): TPU
Anuanu Loa (-40°C a i ʻole ma lalo): PBT, PP, TPU i hoʻololi ʻia
Kaula o loko, Hoʻohana maʻamau, Nā Papahana Koʻikoʻi-Kumukūʻai: PVC (manaʻo wale ʻia ma lalo o nā kūlana kikoʻī)
ʻAʻohe hopena "hoʻokahi-nui-kūpono-āpau" no nā mea uwea optical. Pono ke koho e kau ʻia ma luna o kahi loiloi piha o ke ʻano o ke uwea, nā kūlana hoʻonohonoho, ka waihona kālā, a me ka hilinaʻi lōʻihi.
