Ib hom fiber ntau optic cablethiabntau hom fiber ntau optic cableua hauj lwm txawv lub hom phiaj, ua rau lawv incompatible rau interchangeable siv. Qhov sib txawv xws li cov tub ntxhais loj, lub teeb ci, thiab kev sib kis ntau yam cuam tshuam rau lawv qhov kev ua tau zoo. Piv txwv li, ntau hom fiber ntau optic cable siv LEDs lossis lasers, thaum ib hom fiber ntau optic cable siv cov lasers nkaus xwb, kom ntseeg tau tias cov teeb liab xa mus ntev ntev hauv kev siv xws lifiber optic cable rau telecomthiabFiber optic cable rau FTTH. Kev siv tsis raug tuaj yeem ua rau lub teeb liab degradation, network instability, thiab cov nqi siab dua. Rau kev ua tau zoo nyob rau hauv ib puag ncig zoo lifiber optic cable rau cov ntaub ntawv chawkev siv, xaiv qhov tseeb fiber ntau cable yog qhov tseem ceeb.
Ntsiab Cai
- Tib hom thiab ntau hom cables yog siv raucov hauj lwm txawv. Koj tsis tuaj yeem pauv lawv. Xaiv qhov tsim nyog rau koj cov kev xav tau.
- Tib hom cables ua haujlwm zoo raunyob debthiab cov ntaub ntawv siab ceev. Lawv zoo heev rau telecom thiab cov chaw zov me nyuam.
- Multi-mode cables raug nqi tsawg dua thaum xub thawj tab sis tuaj yeem raug nqi ntau dua tom qab. Qhov no yog vim lawv ua haujlwm rau luv luv thiab muaj cov ntaub ntawv qis dua.
Technical sib txawv ntawm Multi-Mode thiab Single-Mode Cables
Core Diameter thiab Lub Teeb Qhov Chaw
Qhov tseem ceeb txoj kab uas hla yog ib qho tseem ceeb sib txawv ntawmmulti-mode thiab single-mode cables. Multi-mode cables feem ntau muaj cov tub ntxhais loj dua, xws li 50µm txog 62.5µm, nyob ntawm hom (xws li OM1, OM2, OM3, lossis OM4). Nyob rau hauv sib piv, ib hom fiber ntau optic cable nta ib tug me me txoj kab uas hla ntawm kwv yees li 9µm. Qhov sib txawv no ncaj qha cuam tshuam rau hom teeb pom kev zoo siv. Multi-mode cables cia siab rau LEDs lossis laser diodes, thaum ib leeg-hom cables tshwj xeeb tshaj yog siv lasers kom meej thiab tsom teeb kis tau tus mob.
