G.652.D Tib-hom Tsawg Dej Peak Fiber
Hauv kev sib txuas lus fiber optic, ib qho singlemode optical fiber (SMF) yog fiber ntau optical tsim los nqa tsuas yog ib hom ntawm lub teeb - lub transverse hom. Cov qauv yog cov kev daws teeb meem ntawm Helmholtz kab zauv rau nthwv dej, uas yog tau los ntawm kev sib txuas Maxwell qhov sib npaug thiab cov ciam teb. Cov qauv no txhais tau tias txoj kev nthwv dej mus los ntawm qhov chaw, piv txwv li yuav ua li cas cov nthwv dej faib rau hauv qhov chaw. Waves tuaj yeem muaj tib hom tab sis muaj ntau zaus. Qhov no yog qhov xwm txheej ntawm ib hom fibers, qhov twg peb tuaj yeem muaj nthwv dej nrog ntau zaus, tab sis ntawm tib hom, uas txhais tau hais tias lawv tau faib rau hauv qhov chaw tib yam, thiab qhov ntawd muab rau peb ib leeg ntawm lub teeb. Txawm hais tias txoj kab hluav taws xob mus rau qhov sib npaug mus rau qhov ntev ntawm cov fiber ntau, nws feem ntau hu ua transverse hom vim nws cov electromagnetic oscillations tshwm sim perpendicular (transverse) mus rau qhov ntev ntawm cov fiber. Cov qauv G.652 thiab G.657 txhais cov ntaub ntawv siv ntau tshaj plaws ntawm ib hom kev kho qhov muag fiber ntau.
Tshwj tsis yog hais tshwj xeeb, nws feem ntau lees txais ntawm cov kws tshaj lij kev sib tham uas thaum thov singlemode fiber cables lawv yuav ua raws li ITU-T G652.D. Cov qauv no siv tau rau ob qho tib si singlemode OS1 thiab OS2 cables thiab piav qhia txog geometrical, mechanical and transmission attributes of cable and ensure that the cable can be used in the operating wavelengths around 1310nm and 1550nm.
Nco ntsoov tias G.652.D, G.657.A1 thiab G.657.A2 txhua tus muaj tib lub cev loj nrog cov tub ntxhais sab hauv thiab sab nraud ntawm 9μm thiab 125μm, feem. Qhov no txhais tau hais tias cov cables uas tau teev tseg raws li tag nrho peb cov qauv yog sib haum nrog ib leeg.
G.657.A1 vs G.657.A2
G.657.A2 kuj tau ua raws li G.652.D thaum muaj qhov nruj me ntsis khoov lub vojvoog ntawm 7.5mm, piv rau 10mm rau G.657.A1.
Vim tias nws txoj kab nkhaus nruj dua thiab ua raws li G.652.D, G.657.A2 yog qhov nrov siv rau hauv qhov chaw nruj dua nyob rau hauv qhov siab ceev patching teb hauv cov ntaub ntawv chaw. Ntau ntawm peb cov neeg siv khoom los ntawm cov tuam txhab kev sib txuas lus loj kuj tau thov G.657.A2 rau tib lub laj thawj.
