Kev Ntsuas Kho Lus Fiber Fiber Fiber Reactification thiab Kev Rho Tawm

Nws paub txog kev sib txuas lus fiber ntau yog ua raws li txoj ntsiab cai ntawm kev xav tau tag nrho ntawm lub teeb.
Thaum lub teeb sib hais rau hauv nruab nrab ntawm lub cev muaj zog ntawm lub cev, cov tub ntxhais ua kom muaj zog dua li ntawm cov cladding, yog li ntawd lub teeb yuav yauv ua kom tiav rau hauv cov tub ntxhais. Vim tias muaj kev vam meej tag nrho reflections, lub teeb tuaj yeem kis tau los ntawm ib qho kawg mus rau lwm qhov.

Hais kom faib los ntawm kev sib kis hom: Ib hom-hom thiab ntau hom.
Ib hom-hom muaj cov taub tseem ceeb me me thiab tsuas tuaj yeem hloov lub teeb ntawm lub teeb ntawm ib hom.
Ntau hom kev siv kho qhov muag muaj cov txheej txheem loj loj thiab tuaj yeem hloov lub teeb pom kev hauv ntau hom.
Peb kuj tuaj yeem paub qhov txawv ntawm ib-hom optical fiber ntau los ntawm ntau-hom optical fiber los ntawm cov xim ntawm cov tsos.

Feem ntau-hom optical fibers muaj lub tsho daj thiab xiav lub txuas, thiab cov cable tseem ceeb yog 9.0 μm. Muaj ob lub hauv paus wavelengths ntawm ib-hom fiber ntau: 1310 nm thiab 1550 nm. 1310 NM feem ntau yog siv rau luv luv-deb, nruab nrab-nrug lossis ntev-kev sib kis, thiab 1550 nm yog siv rau kev sib nrug ntev thiab ultra-ntev-ntev. Cov kev sib kis mus deb yog nyob ntawm tus kis lub zog ntawm lub tshuab kho qhov muag. Tus kis nrug ntawm 1310 nm ib-hom chaw nres nkoj yog 1050 nm, thiab lwm yam chaw nres nkoj yog 40 km, 70 km, 100 km, thiab lwm yam, 100 km, thiab lwm yam.

Ntau hom optical fibers yog feem ntau txiv kab ntxwv / grey tsho nrog dub / be beiger sib txuas, 50.0 μm cores. Qhov chaw wavelength ntawm ntau hom fiber ntau yog feem ntau 850 nm. Tus kis nrug ntawm ntau hom fiber ntau yog luv luv, feem ntau tsis pub dhau 500 m.
