Rau siv hauv ib hom fiber ntau _ yog siv zoo dua. Nqe lus piav qhia: Semiconductor optical amplifiers muaj lub zog siv tsawg. Muaj ib hom qauv ua rau lawv tsim nyog thiab haum rau siv nyob rau hauv ib hom fiber ntau.
Dab tsi yog daim ntawv thov ntawm optical amplifier?
Cov kev siv ntawm optical amplifiers yog: Ib lub amplifier tuaj yeem txhawb nqa lub zog (nruab nrab) ntawm lub laser tso zis mus rau qib siab dua (→ tus tswv oscillator fais fab amplifier=MOPA). Nws tuaj yeem tsim lub zog siab tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv ultrashort pulses, yog tias lub zog khaws cia tau muab rho tawm hauv lub sijhawm luv luv.
Muaj pes tsawg hom optical amplifier technologies muaj?
Muaj 2 hom ntawm cov khoom siv kho qhov muag; OFA (Optical Fiber Amplifier) thiab SOA (Semiconductor Optical Amplifier). Muaj 2 hom OFAs ntxiv; EDFA (Erbium-Doped Fiber Amplifier) thiab FRA (Fiber Raman Amplifier).
Muaj pes tsawg hom kev nthuav tawm muaj nyob hauv ib hom Fibre?
Kev piav qhia: Muaj ob hom kev nthuav tawm hauv ib hom fibers. Ob hom no zoo sib xws tab sis lawv cov dav hlau polarization yog orthogonal. Hauv cov fibers tiag tiag, muaj qhov tsis zoo xws li kev hloov pauv hauv qhov ntsuas qhov ntsuas tsis pom.
Qhov twg optical amplifier muaj qhov zoo dua?
Kev piav qhia: Raws li piv rau txhua qhov kev nthuav dav, Raman amplification yog qhov zoo dua. Nws muaj nws tus kheej-theem kev sib piv ntawm lub twj tso kua mis ntawm lub teeb liab ua ke nrog dav nce bandwidth piv rau lwm cov txheej txheem nonlinear.

Dab tsi yog qhov ceev dua cable lossis fiber ntau optics?
Fiber-optic internet kev pabcuam yog nrawm dua piv rau cable network nrog qhov nrawm tsis tsawg dua 250-1,000 Mbps hauv ob qho kev qhia . Puas yog fiber ntau lossis cable Internet zoo dua? Cable thiab fiber ntau yog ob qho tib si kev sib txuas hauv internet uas txhim khu kev qha thiab tuaj yeem ncav cuag gigabit ceev (1,000 Mbps), tab sis fiber ntau yog qhov zoo dua rau kev xa cov nrawm tshaj plaws, tshwj xeeb tshaj yog rau kev xa tawm bandwidth.
Dab tsi yog qhov kev piav qhia zoo tshaj plaws ntawm kev ua tswv cuab hauv ntau ntau?
Yuav muaj ntau caum (aka tenancy in sever alty) yog thaum vaj tse yog tswv los ntawm ib tug neeg los yog ib tug raws li txoj cai, muab tus tswv nrog tag nrho cov tswj av Tus Lub npe yog muab los ntawm qhov tseeb tias tus tswv yog "severed"
Ntau npaum li cas fiber ntau splicers ua?
Cov nyiaj hli nruab nrab ntawm fiber ntau hauv Tebchaws Meskas yog $ 55, 575 ib xyoos lossis $ 28.50 toj ib teev. Cov haujlwm nkag qib pib ntawm $ 45, 318 toj ib xyoo thaum cov neeg ua haujlwm paub txog feem ntau tau txog $ 195, 000 toj xyoo .
Siv ntau hom fiber ntau nyob qhov twg?
Multimode Fiber Optic Cable Daim ntawv thov no feem ntau yog siv rau ncua deb, cov ntaub ntawv thiab daim ntawv thov audio / video hauv LANs RF broadband signals, xws li cov tuam txhab cable uas nquag siv, tsis tuaj yeem ua. kis tau los ntawm multimode fiber ntau.
Kuv puas xav tau ntau hom fiber ntau?
Dav dav, daim ntawv thov ntau tshaj plaws rau Multi-Mode fiber ntau cable yog los tsim lub nraub qaum rau lub tuam txhab network. Yog tias koj tab tom saib ntawm 802.11ac lossis tshiab dua Wi-nkaus nkag cov ntsiab lus, Multi-Mode fiber nraub qaum yog qhov yuav tsum tau ua kom tau txais kev nrawm tshaj plaws ntawm koj cov ntsiab lus nkag .
