Kodi Kusiyana Ndi Chiyani: Single Mode vs Multimode Fiber?

Ulusi wowoneka bwino ndi ulusi wosinthika, wowoneka bwino wopangidwa ndi galasi lotuluka kapena pulasitiki, wokhuthala pang'ono kuposa tsitsi la munthu.Ulusi wa kuwala umagwiritsidwa ntchito nthawi zambiri ngati njira yotumizira kuwala pakati pa malekezero awiri a ulusi ndikupeza kugwiritsidwa ntchito mokulira mu mauthenga a fiber-optic, komwe amalola kufalikira kwa mtunda wautali komanso ma bandwidth apamwamba kuposa zingwe zamawaya.Ulusi wowoneka bwino nthawi zambiri umakhala ndi phata lowoneka bwino lozunguliridwa ndi chinthu chotchinga chowoneka bwino chokhala ndi index yotsika ya refraction.Kuwala kumasungidwa pachimake ndi chodabwitsa cha kuwunikira kwathunthu kwamkati komwe kumapangitsa kuti ulusiwo ukhale ngati waveguide.Mwambiri, pali mitundu iwiri ya ulusi wowoneka bwino: ulusi womwe umathandizira njira zambiri zofalitsira kapena njira zopingasa zimatchedwa multimode fibers (MMF), pomwe zomwe zimathandizira mawonekedwe amodzi zimatchedwa single mode fibers (SMF).Single mode vs multimode fiber: pali kusiyana kotani pakati pawo?Kuwerenga lembali kukuthandizani kupeza yankho.

Single Mode vs Multimode Fiber: Kodi single mode Optical fiber ndi chiyani?

Mukulankhulana kwa fiber-optic, single mode optical fiber (SM) ndi fiber optical fiber yomwe imapangidwira kunyamula kuwala molunjika pansi pa fiber - njira yodutsa.Pa single mode kuwala CHIKWANGWANI, ziribe kanthu kuti imagwira ntchito pa 100 Mbit/s kapena 1 Gbit/s tsiku mitengo, kufala mtunda akhoza kufika osachepera 5 Km.Nthawi zambiri, imagwiritsidwa ntchito potumiza chizindikiro chakutali.

Single Mode vs Multimode Fiber: Multimode Optical fiber ndi chiyani?

Multimode optical fiber (MM) ndi mtundu wa fiber optical fiber yomwe imagwiritsidwa ntchito kwambiri polankhulana pamtunda waufupi, monga mkati mwa nyumba kapena pasukulu.Liwiro lodziwika bwino komanso malire a mtunda ndi 100 Mbit/s pa mtunda wofikira 2 km (100BASE-FX), 1 Gbit/s mpaka 1000m, ndi 10 Gbit/s mpaka 550 m.Pali mitundu iwiri ya ma index a multimode: index index ndi graded index.

Kodi pali kusiyana kotani pakati pa single mode optical fiber ndi multimode?

Kuchepetsa: Kutsika kwa ulusi wa multimode ndikokwera kuposa ulusi wa SM chifukwa cha mainchesi ake okulirapo.Chingwe cha fiber cha single mode ndi chopapatiza kwambiri, kotero kuwala komwe kumadutsa mu zingwe za fiber Optical sikumawonekera nthawi zambiri, zomwe zimapangitsa kuti kuchepeko kuchepe.

Core diameter:Kusiyana kwakukulu pakati pa multimode ndi single mode fiber ndikuti choyambirira chimakhala ndi mainchesi okulirapo, nthawi zambiri chimakhala ndi mainchesi apakati a 50 kapena 62.5 µm ndi m'mimba mwake wa 125 µm.Ngakhale ulusi wamtundu umodzi uli ndi mainchesi pakati pa 8 ndi 10 µm ndi m'mimba mwake wa 125 µm.
