Fiber optics, also spelled fiber optics, kaʻepekemaoka hooili anaʻikepili, leo, a me nā kiʻi ma o ka hele ʻana o ka mālamalama ma o nā kaula lahilahi a aniani.Inkelepona, ua pani ʻia ka ʻenehana fiber optickeleaweuwea i lokomamao loa keleponalaina, a hoʻohana ʻia e hoʻopilikamepiulai lokopūnaewele puni honua.ʻO ka fiberopticsʻo ia ke kumu o nā fiberscopes i hoʻohana ʻia i ka nānā ʻana i nā ʻāpana o loko o ke kino (endoscopy) a i ʻole ke nānā ʻana i loko o nā huahana i hana ʻia.

ʻO ke kumu maʻamau o ka fiber optics he fiber lahilahi lauoho i hana ʻia i kekahi manawapalakiaka o ka pinepine oaniani.He 125 micrometres (μm) ke anawaena aniani aniani maʻamau, a i ʻole 0.125 mm (0.005 iniha).ʻO kēia maoli ke anawaena o ka pale, a i ʻole ka papa hoʻohālike o waho.ʻO ke kumu, a i ʻole ka cylinder hoʻouna i loko, hiki ke loaʻa ke anawaena e like me 10μm.Ma o ke kaʻina hana i ʻike ʻia hehuina noonoo o loko,māmānā kukuna i hoʻopaʻa ʻia i loko o ka fiber canhoolahai loko o ke kumu no kahi mamao loa me ka liʻiliʻi o ka attenuation, a i ʻole ka emi ʻana o ka ikaika.'Oko'a ke degere o ka attenuation ma luna o ka mamao e like me ka nalu o ka malamalama a me kahaku meleo ka pulupulu.

I ka wā i hoʻokomo ʻia ai nā fiber aniani o ka hoʻolālā kumu/ʻaʻahu i nā makahiki 1950, ʻo ka loaʻa ʻana o nā haumia i kaupalena ʻia kā lākou hana i nā lōʻihi pōkole i lawa no ka endoscopy.I ka makahiki 1966, nā ʻenekini uilaCharles Kaoa ʻo George Hockham, e hana ana ma ʻEnelani, ua manaʻo e hoʻohana i nā fibers nokelepona, a i loko o ʻelua mau makahikisilikaua hana ʻia nā pulu aniani me ka maʻemaʻe kūponoinfraredHiki i nā hōʻailona māmā ke hele ma waena o lākou no 100 km (60 mau mile) a ʻoi aʻe me ka hoʻoikaika ʻole ʻia e nā mea hana hou.I ka makahiki 2009 ua loaʻa iā Kao kaMakai Nobeli ka Physics no kāna hana.ʻO nā pulupulu i hana ʻia me ka polymethylmethacrylate,polystyrene, a i ʻolepolycarbonate, ʻoi aku ka liʻiliʻi o ka hana ʻana a ʻoi aku ka maʻalahi ma mua o nā fibers aniani, akā ʻoi aku ka nui o ka attenuation o ka mālamalama i kaohi i ko lākou hoʻohana ʻana i nā loulou pōkole loa i loko o nā hale a i ʻole.nā kaʻa kaʻa.

Hoʻohana pinepine ʻia ke kelepona Optical meinfraredkukui i loko o nā kaha nalu o 0.8–0.9 μm a i ʻole 1.3–1.6 μm—nā nalu i hana maikaʻi ʻia enā diodes māmāa i ʻolesemiconductor nā lasersa me ka emi loa o ka attenuation i loko o nā pulu aniani.Hana ʻia ka nānā ʻana o Fiberscope i ka endoscopy a i ʻole ka ʻoihana i nā nalu i ʻike ʻia, hoʻokahi pūʻulu o nā fibers e hoʻohana ʻia e.hoʻomālamalamaka wahi i nānā ʻia me ka māmā a me kekahi pūʻolo e lawelawe ana ma ke ʻano he elongatedlekiōno ka lawe ana i ke kii i kamaka kanakaa i ʻole he pahupaʻiwikiō.

Hoʻololi nā mea hoʻokipa fiber optic i nā hōʻailona māmā i nā hōʻailona uila no ka hoʻohana ʻana e nā mea hana e like me nā pūnaewele kamepiula.Aia kēia mau mea electro-optical me ka mea ʻike maka, ka mea hoʻonui haʻahaʻa haʻahaʻa, a me ka circuit condition conditioning.Ma hope o ka hoʻololi ʻana o ka mea ʻike maka i ka hōʻailona ʻōpika e hiki mai ana i hōʻailona uila, hoʻonui ka mea hoʻonui iā ia i kahi pae kūpono no ka hana hōʻailona hou.ʻO ke ʻano modulation a me nā koi hoʻopuka uila e hoʻoholo i ka mea e pono ai ka circuitry ʻē aʻe.

Hoʻohana nā mea hoʻokipa fiber optic i nā junction maikaʻi-ʻole (PN), photodiodes positive-intrinsic negative (PIN), a i ʻole avalanche photodiodes (APD) ma ke ʻano he mea ʻike maka.Hoʻouna ʻia ka hōʻailona kukui e hiki mai ana e ka fiber optic transmitter (a i ʻole transceiver) a hele ma ke ʻano hoʻokahi a i ʻole multi-mode cable optical, e pili ana i ka hiki o ka mea hana.Hoʻololi ka demodulator data i ka hōʻailona kukui i kona ʻano uila mua.I loko o nā ʻōnaehana fiber optic paʻakikī, hoʻohana pū ʻia nā ʻāpana ʻāpana hawewe (WDM).

Nā Semiconductor a me Photodiodes

Hiki i ka ʻikepili ʻo Engineering360 SpecSearch ke koho i nā huahana ma ke ʻano semiconductor a me ke ʻano photodiode.Hoʻohana ʻia nā ʻano semiconductor ʻelua i nā mea hoʻokipa fiber optic.

Hoʻohana ʻia nā semiconductor silikon i nā mea hoʻokipa pōkole pōkole me ka laulā o 400 nm a 1100 nm.

Hoʻohana ʻia nā semiconductors indium gallium arsenide i nā mea hoʻokipa lōʻihi me ka laulā o 900 nm a 1700 nm.

E like me ka mea i hōʻike ʻia ma luna, hoʻohana nā mea hoʻokipa fiber optic i ʻekolu ʻano like ʻole o nā photodiodes.

Hoʻokumu ʻia nā hui PN ma ka palena o kahi semiconductor P-type a me N-type, maʻamau i loko o kahi aniani hoʻokahi ma o ka doping.

Loaʻa i nā kiʻi kiʻi PIN kahi ʻāpana intrinsic neutrally-doped ma waena o nā wahi semiconducting P-doped a me N-doped.

ʻO nā APD nā kiʻi kiʻi kiʻi PIN kūikawā e hana ana me nā volt reverse bias kiʻekiʻe.

Nā mea hoʻonui a me nā mea hoʻohui

Hoʻohana nā mea hoʻokipa fiber optic i nā mea hoʻonui haʻahaʻa haʻahaʻa a i ʻole transimpedance amplifier.

Me nā hāmeʻa haʻahaʻa haʻahaʻa, hoʻemi ka bandwidth a me ka leo hoʻokipa me ke kūʻē.

Me nā mea trans-impedance, pili ka bandwidth o ka mea hoʻokipa e ka loaʻa o ka amplifier.

ʻO ka mea maʻamau, loaʻa nā mea hoʻokipa fiber optic i kahi mea hoʻopili hiki ke hoʻoneʻe ʻia no nā pili i nā mea hana ʻē aʻe.Aia nā koho i D4, MTP, MT-RJ, MU, a me SC

Hana ka mea loaa

Ke hoʻohana nei ʻo Engineering360 i nā huahana, pono nā mea kūʻai aku e kuhikuhi i kēia mau ʻāpana no ka hana ʻana o ka fiber optic receiver.

ʻO ka helu ʻikepili ka helu o nā bits i hoʻouna ʻia i kēlā me kēia kekona, a he hōʻike ia o ka wikiwiki.

ʻO ka manawa piʻi o ka mea hoʻokipa he hōʻike ia o ka wikiwiki, akā e hōʻike ana i ka manawa i koi ʻia no ka hoʻololi ʻana o kahi hōʻailona mai kahi 10% a 90% mana.

Hōʻike ka Sensitivity i ka hōʻailona optical nāwaliwali loa i hiki ke loaʻa i ka mea hana.

Pili ka laulima dynamic i ka sensitivity, akā hōʻike i ka laulā mana ma luna o ka mea hana.

ʻO ka pane ka lākiō o ka ikehu ʻālohilohi ma watts (W) i ka hopena kiʻi kiʻi i nā amperes (A).
