Kev sib txuas lus fiber ntau yog txheej txheem ntawm cov ntaub ntawv xa xov rau hauv uas cov xov tooj hluav taws xob siv hluav taws xob tau siv los ua cov kab ke, thiab hluav taws xob hluav taws xob hauv cov hluav taws xob kho qhov muag tau ua lub luag haujlwm ntawm lub teeb liab thauj. Ntawm txhua qhov kev sib txuas lus uas twb muaj lawm, kab xa hluav taws xob fiber ntau muaj cov kab ntau tshaj plaws, uas tuaj yeem ntsuas hauv terabits ib ob.

Khoom siv fiber ntau

Ib qho hluav taws xob fiber ntau muaj iav fiber tam ua lub nruab nrab ntawm tus neeg sawv cev ntawm lub teeb, ib puag ncig los ntawm lub khob hnab iav uas muaj qhov ntsuas qis dua qis dua qhov nruab nrab tus neeg xyuas pib. Lub teeb ntom nti, tsim los ntawm diode lossis semiconductor laser, nthuav tawm raws tus neeg coj ntawm chaw nruab nrab, tsis tau tawm nws vim lub hnab ntawv iav.

Thaum Lub Plaub Hlis 22, 1977, hauv Long Beach, California, General Xov Tooj thiab Electronics thawj cov siv hluav taws xob los nqa xov tooj ntawm 6 Mbps.

Keeb kwm ntawm kev tsim

Lub tshuab thev naus laus zis ntau ntawm cov ntaub ntawv siv cov khoom siv hluav taws xob tsis yog qhov tshwj xeeb tshaj yog tham thiab tau tsim rau lub sijhawm ntev. Rov qab rau xyoo 1840, cov kws tshawb fawb Jacques Babinette thiab Daniel Colladon tau ua qhov kev sim nrog kev hloov ntawm cov kev taw qhia ntawm lub teeb flux los ntawm kev tsis kam. Xyoo 1870, John Tyndall luam tawm ib txoj haujlwm ntawm qhov kaj, hauv qhov nws xa mus rau kev sim ua los ntawm Babinette thiab Colladon. Thawj qhov kev siv tswv yim tshiab ntawm kev siv thev naus laus zis yog 20s ntawm xyoo pua XX. Tom qab ntawd ob tus neeg sim John Bird thiab Clarence Hasnell tau qhia rau pej xeem txog kev xa cov duab los ntawm cov leeg ntsia hlau. Lub sijhawm no tau siv los ntawm Dr. Heinrich Lamm los tshuaj xyuas cov neeg mob.

Cov thawj cov roj carbon fiber ntau tau tsim thiab tsim cov khoom tiav los ntawm kev sim hauv xyoo 1952 los ntawm tus kws kho mob Narinder Singh Kapani. Nws tsim txoj hlua ntawm cov iav filaments, nrog cov tub ntxhais tseem ceeb thiab cov ntawv luam, uas muaj qhov sib txawv ntawm qhov ntsuas pom. Cov cladding nyob rau hauv Kapani cable tau txais kev pab raws li daim iav rau cov tub ntxhais pob tshab ntau dua, uas daws cov teeb meem ntawm kev tawg nrawm ntawm lub teeb ntas. Vim tias qhov no, lub teeb hluav taws xob tau pib mus txog qhov kawg ntawm qhov kho qhov muag, uas ua rau nws siv tau cov qauv no ntawm cov ntaub ntawv xa mus los ntawm kev ncua ntev.

Xyoo 1960, nrog kev tsim tsim thiab txhim kho ntawm cov khoom hluav taws xob kom txaus ntawm cov khoom hluav taws xob GaAs lasers, qhov teeb meem nrog lub teeb pom kev tau daws tau. Xyoo 1970, cov kws tshaj lij ntawm Corning Incorporated tau tsim cov khoom lag luam zoo ntawm cov kab hluav taws xob fiber ntau uas tsis siv rov ua dua nyob hauv nws txoj haujlwm. Qhov rov tshwm sim ntawm cov kev tsim tshiab tau muab lub zog txhawb rau kev tsim kho hom tshiab ntawm kev sib txuas xov hlau.

Tus nqi ntawm kev siv fiber ntau thev naus laus zis yog qhov txo qis, uas ua rau qhov kev pabcuam no sib tw nrog cov kev pabcuam ib txwm muaj.

Niaj hnub no, kab xev fais fab xov tooj yog txoj kev ceev tshaj plaws ntawm kev xa cov ntaub ntawv; nws yog siv los tsim kom muaj kev kub ceev hauv Is Taws Nem, hauv tshuaj thiab ntau thaj chaw. Fiber ntau tau nteg nyob thoob plaws cov teb chaws thiab thoob plaws ntug dej hiav txwv rau ntau kaum lab ntawm mais, tab sis txawm tias qhov no tsis cuam tshuam rau cov ntaub ntawv xa mus ntau. Yog li no, txawm hais tias tus nqi tsim nyog ntawm cov khoom siv thiab cov cuab yeej siv, muaj fiber ntau thev naus laus zis txuas ntxiv txuas ntxiv txhim kho thiab yog txoj kev nyiam tshaj plaws los hloov cov ntaub ntawv sai.
