Qhov sib txawv ntawm G652, G657A, G655 thiab G654
Optical fiber incudling qee hom, Kuv nyob hauv qhov tsis meej thaum kuaj xyuas tau zoo.Yuav siv sijhawm ntev los kuaj xyuas, thiab ntshai ua yuam kev. Txhawm rau ua kom cov neeg siv khoom kawm paub ntau ntxiv txog qhov kho qhov muag cable, luv luv nthuav dav qhov txawv ntawm cov khoom siv khoos phis tawm.
Cov kho qhov muag tau tsim los ua kom tau raws li qhov kho qhov muag, kev siv tshuab lossis ib puag ncig kev ua tau zoo.Nws yog kev sib txuas lus cable sib dhos uas tuaj yeem siv tau tus kheej lossis pawg. Active Optical cable yog qhov tseem ceeb xa cov cuab yeej ntawm ntau cov xov xwm network hauv cov tib neeg.
Optical cable yog muaj qhov tseem ceeb, txheej thiab tsho.
Cov tub ntxhais: Qib siab dua qhov ntsuas siab, rau qhov ua kom sib kis;
Txheej Txheej: Cov ntawv qis dhau los ua cov cim, ua rau tag nrho cov kev cuam tshuam nrog cov tub ntxhais;
Tsho: Siab zog, tuaj yeem tiv thaiv kev cuam tshuam ntau dua, tiv thaiv fiber ntau.
Hom fiber ntau kho qhov muag thiab qhov sib txawv:
G652: Txheem ib hom fiber ntau , xoom dispersion kis yog nyob rau hauv 1300nm, faib rau G652A, B, C, D.The lub ntsiab sib txawv yog PMD. Nws qhov tshwj xeeb yog tias qhov fiber kis tau yog tsawg heev thaum ua haujlwm wavelength yog 1300nm, qhov sib kis tau ntawm lub kaw lus tsuas yog txwv los ntawm poob;
G657A: Muaj rau hauv D, E, S, C thiab L5 wavebands. Nws tuaj yeem ua haujlwm rau tag nrho cov kev ua haujlwm yoj ntev ntawm 1260-1625nm. Nrog rau kev ua tau zoo kawg nkaus khoov thiab cov kev xav tau ntawm qhov loj me me tau yog;
G655: Tsis yog xoom dispersion-hloov hluav taws xob (NZ-DSF) muaj 655A, B, C; Tus yam ntxwv tseem ceeb yog tias kev tawg ntawm 1550nm yog ze rau xoom, tab sis tsis xoom. Nws yog kev txhim kho-dispersion fiber ntau los txo plaub-yoj sib xyaw;
G654: Ultra qis poob kho qhov muag qhov fiber ntau , feem ntau yog siv rau transoceanic optical cable. Cov tub ntxhais kawm sib txawv yog SiO2 ntshiab, thaum cov neeg zoo tib yam yuav tsum tau doped nrog germanium. Kev poob ze ze 1550nm yog qhov tsawg kawg nkaus, tsuas yog 0.185dB / km, qhov kev tawg yog qhov loj, sib tw 17 ～ 20 ps / (nm · km), Tab sis qhov dispersion yog xoom hauv thaj tsam 1300nm wavelength.
Peb tuaj yeem pom los ntawm saud tias lawv qhov sib txawv ntawm cov fiber ntau, dispersion thiab poob.
