Khoom Description
Khoov Insensitive Ib hom Optical Fiber (G.657.A1)
Daim ntawv thov ntawm Ib Hom G657A1 Optical Fiber
Tag nrho cov kev siv cable, 1260-1626nm puv band kis tau tus mob, FTTH kev kub ceev kho qhov muag routing, kho qhov muag cable nyob rau hauv me me khoov vojvoog, me me-loj optical fiber cable thiab ntaus ntawv, L-band.
Muaj feem xyuam rau ntau yam qauv ntawm optical cables, FTTH high-speed optical routing, kho qhov muag cables nrog me me dabtsi yog khoov vojvoog yuav tsum, optical fiber li, thiab lwm yam.
G.657.A1 vs G.652.D
Qhov sib txawv tseem ceeb ntawm G.657.A1 thiab G.652.D yog qhov tsawg kawg nkaus khoov lub vojvoog ib lub cable tuaj yeem khoov yam tsis muaj cable ua rau lub network tsis ua haujlwm.
G.657.A1 muaj lub vojvoog khoov ntawm 10mm yam tsis muaj kev cuam tshuam kev ua haujlwm. Whereas G.652.D muaj qhov loj dua qhov qis qis qis ntawm 30mm.
Nco ntsoov cov kab hluav taws xob khoov no yog rau ib qho singlemode cables nyob rau hauv thawj daim ntawv tsim nrog tsuas yog lawv cov thawj buffered txheej thiab ua ntej lawv muab cov txheej txheem los yog muab tso rau hauv multicore kev tsim kho raws li cov kev hloov pauv rau cable kuj tseem cuam tshuam rau qhov tsawg kawg nkaus khoov vojvoog.
Raws li xws li, cov kab tuab tuab lossis loj dua cov kab hluav taws xob sib txuas ntau dua feem ntau tsis siv G657.A1 lossis A2 cores vim qhov kev txwv ntawm qhov khoov lub vojvoog yog qhov kev txwv lub cev ntawm kev tsim kho cable thiab tsis yog lub iav cores.
G.657.A1 raws li fibers yogtau sib xws nrog cov tes hauj lwm uas tau teeb tsa thiab muab cov khoom kho kom zoo dua qub. Nrog qis qis qis qis, zoo meej fiber ntau geometry thiab nruj fiber ntau txoj kab uas hla tolerances, lawv zoo kawg nkaus haum rau qhov system xav tau hauv LAN tes hauj lwm.
Raws li lub hauv paus ntsiab lus ntawm kev sib raug zoo nrog G.652 fiber, G.657 fiber ntau muab faib ua A thiab B fiber. Nyob rau tib lub sij hawm, raws li lub hauv paus ntsiab lus ntawm qhov tsawg kawg nkaus khoov vojvoog, qib khoov tau muab faib ua ob qib, 1 thiab 2.
G.657.A1 fiber ntau dabtsi yog khoov kuj yam ntxwv
Piv nrog rau lwm hom fibers ib leeg, qhov tseem ceeb tshaj plaws ntawm G.657 fiber ntau yog tias nws tsis rhiab rau dabtsi yog khoov. Qhov no txhais tau hais tias qhov khoov poob ntawm G.657 fiber ntau yog me me. G.657 fiber ntau kho qhov muag muaj qhov zoo bending kuj, ua rau nws haum rau optical fiber nkag network, nrog rau ntau yam thaiv nyob rau hauv lub tsev qhov twg lub optical fiber nkag network davhlau ya nyob twg nyob.
G.657.A1 muaj qhov tsawg kawg nkaus khoov vojvoog ntawm 10mm thiab yog siab tshaj G.652 Ib hom Optical Fiber.
Yam ntxwv ntawm Ib Hom G657A1 Optical Fiber
Txaus siab thiab superior rau cov kev xav tau ntawm ITU-T G.652.D/G.657.A1;
Kev ua tau zoo ntawm Bending Resistance;
Tau tshaj G.652 ib hom fiber ntau, tag nrho-band kis tau tus mob los ntawm 1260nm mus rau 1626nm;
Tsawg PMD ua tau raws li qhov xav tau ntawm kev kub ceev thiab kev sib kis mus ntev;
Siab tiv thaiv kev qaug zog ua kom lub neej ntev nyob rau hauv me me dabtsi yog khoov vojvoog;
