Cov fiber ntau rau hauv tsev (FTH) kev siv roj hluav taws xob ultra {0} high {1} {nyias khob lossis cov ntaub ntawv xa cov ntaub ntawv raws li lub teeb pom kev. Hauv 2024, cov fiber ntau cov ntaub ntawv sau tau mus txog cov ntaub ntawv tshiab ntawm 10.3 lab peb dhau los, nrog fiber ntau cov tsev neeg dhau los, nrog rau cov tsev neeg Asmeskas (source Tsis zoo li cov xov tooj liab uas muaj cov hluav taws xob tsis muaj hluav taws xob tuaj yeem hloov cov ntaub ntawv ntawm kev nce 100 npaug thaum tswj cov teeb liab zoo dua li ncua sijhawm ntev dua.

Cov cuab yeej hloov kho no ua haujlwm vim tias peb cov tub neej lub neej xav tau ntau bandwidth. Nruab nrab ntawm cov chaw taws teeb ua haujlwm, 4k streaming ntawm ntau pab kiag li lawm cov tsev, thiab ntse dua cov tsev neeg tam sim no yuav tsum tau muab cov xov tooj ntawm cov neeg tooj liab tsis tuaj yeem xa. Lub ntiaj teb fiber ntau rau hauv tsev kev ua lag luam tau muaj nuj nqis ntawm $ 56.03 thiab yog npaj rau 12,4% txhua xyoo (Tau los: Grandviewresearch.com, 2024).

Yuav ua li cas thev naus laus zis tiag tiag ua haujlwm

Ntawm nws cov tub ntxhais, FTHT Technology Relies ntawm lub ntsiab cai los ntawm Physics: kev cuam tshuam tag nrho hauv kev xav. Txhua lub fiber ntau cable muaj cov ntxig ntawm iav lossis yas}} ntau npaum li tib neeg cov plaub hau- nrog tus qauv sab hauv tshwj xeeb. Thaum lub teeb nkag ib qho kawg ntawm cov fiber ntau, nws bounces tawm ntawm cov phab ntsa ntawm cov qauv hauv ib lub zigzag, taug kev tag nrho ntev yam tsis tau khiav tawm.

Lub kaw lus siv peb lub wavelengths ntawm lub teeb ib txhij dhau los ntawm lub thev naus laus zis hu ua wavelength divisen multiplexing (WDM). Cov ntaub ntawv nqes dej (los ntawm Is Taws Nem rau koj lub tsev) feem ntau siv 1490 nanometer wavelength teeb, thaum pem hauv koj lub tsev mus rau Is Taws Nem) siv 1310 nm. Ib feem peb wavelength ntawm 1550 nm tuaj yeem nqa cov kev pabcuam ntxiv xws li video. Ntau lub {{6} wavelengthwhing txoj kev tso cai rau ib tug ib co fiber ntau strand los lis cov nqi bidirectional tsis muaj kev cuam tshuam.

Kev nrawm thiab latency: Vim li cas fiber ntau outperforms txhua yam

Qhov kev ua tau zoo sib kis ntawm cov fiber ntau thiab lwm cov thev naus laus zis tsis yog marginal - nws yog exponential. Cov muaj txiaj ntsig Fiber nyob nruab nrab ntawm Latency piv rau 100 milliseconds nrog cable Internet (chaw: Vij siv.com, 2024). Txog cov ntsiab lus teb, uas muaj 83-millisecond qhov sib txawv yog lub sijhawm ntawm kev sib tham dawb thiab ib qho uas muaj kev chim siab qeeb.
