How do fiber optic cables work？

Lithapo tsa fiber optic li sebetsa joang? Bona ke bothata boo batho ba bangata ba ka kopanang le bona ha ba sebelisa Marang-rang le litheknoloji tse ling tse itšetlehileng ka marang-rang a fiber optic. Lithapo tsa fiber optic ke karolo ea bohlokoa ea mekhoa ea sejoale-joale ea puisano le data. Lithapo tsena li entsoe ka likhalase tse tšesaane kapa lithapo tsa polasetiki tse sebelisang khanya ho fetisa data ka lebelo le holimo haholo.

Lithapo tsa inthanete tsa fiber optic ke e 'ngoe ea lisebelisoa tse atileng haholo tsa likhoele tsa fiber optic. Lithapo tsena li etselitsoe ho tsamaisa data ea inthanete ka lebelo le leholo ho feta likhoele tsa khale tsa koporo. Sena se finyelloa ka ho sebelisa maqhubu a khanya a tsamaeang ka likhoele tsa fiber optic, e leng se lumellang hore ho be le litekanyetso tse phahameng tsa ho fetisa lintlha. Likopano tsa li-fiber optic cable tse felisitsoeng le tsona li ntse li tsebahala haholo hobane li fana ka mokhoa o bonolo le o sebetsang oa ho kenya mohala oa fiber optic libakeng tse fapaneng. Lithapo tsena tsa pele tsa fiber optic li fumaneha ka mefuta e fapaneng joalo kaka harelelikhoele tsa ka ntle'me li loketse ho sebelisoa ka ntle ho lebokose.

Joale, hantle-ntle lithapo tsa fiber optic li sebetsa joang? Ts'ebetso e qala ka ho fetisetsa data ka mokhoa oa li-pulses tsa leseli. Li-pulse tsena tse khanyang li hlahisoa ke lisebelisoa tse bitsoang laser diode, tse khonang ho ntša khanya ea bolelele bo itseng ba maqhubu. Leqhubu le khanyang le feta bohareng ba thapo, e pota-potiloeng ke ntho e nang le index e tlase ea refractive e bitsoang cladding. Tlhophiso ena e lumella li-pulse tse khanyang ho bonahatsa marako a mokokotlo oa cable, ka mokhoa o hlakileng "ho bonahatsa" leseli ho khutlela thapong. Ts'ebetso ena, e bitsoang total internal reflection, e lumella maqhubu a leseli ho tsamaea sebaka se selelele ntle le ho lahleheloa ke matla.

Ha ho tluoa tabeng ea ho kopanya likhoele tsa fiber optic, mokhoa ona o bonolo haholo. Ho kopanya ho kenyelletsa ho kopanya likhoele tse peli tsa fiber optic hammoho ho etsa mohala o tsoelang pele oa phetiso. Sena se ka etsoa ho sebelisoa mekhoa e fapaneng, ho kenyelletsa le ho kopanya mechine. Fusion e akarelletsa ho sebelisa mochine ho hokahanya lipheletsong tsa likhoele tse peli ebe ho sebelisoa arc ea motlakase ho li kopanya. Mechanical splicing, ka lehlakoreng le leng, e sebelisa likhokahano tse khethehileng ho kopanya likhoele hammoho ntle le tlhoko ea ho kopanya.

Qetellong, likhoele tsa fiber optic ke karolo ea bohlokoa mekhoeng ea sejoale-joale ea puisano le phetiso ea data. Ho oyi, re motlotlo ho fana ka mefuta e mengata ea lithapo tsa fiber optic, ho kenyeletsoa lithapo tsa fiber optic tse entsoeng esale pele, tse etselitsoeng ho fihlela litlhoko tse fapaneng tsa bareki ba rona. Lithapo tsa rona tsa fiber optic ha li potlake feela ebile lia tšepahala, hape li tšoarella nako e telele le ho boloka chelete e ngata. Ka mekhoa e tsoetseng pele ea tlhahiso, re khona ho hlahisa likhoele tsa fiber optic tse ka pele ho theknoloji, ho netefatsa hore bareki ba rona ba fumana lihlahisoa tse ntle ka ho fetisisa.
