Kukweza zinthu kumafuna kuwunika momwe zinthu zilili panopa komanso zolinga zamtsogolo. Pofuna kuchepetsa kusokonezeka pang'ono momwe zingathere, kukhazikitsa pang'onopang'ono ndikofunikira.

Mwachitsanzo, kusinthana ulusi wa multimode ndi ulusi wa single-mode m'malo osungira deta ndi njira yanzeru yowonjezerera magwiridwe antchito komanso kutsimikizira mtsogolo kuti zikhale patsogolo pa zomwe zikufunidwa.

Kusinthana ndi Ukadaulo Watsopano

Kudziwa zatsopano za ulusi kumawonjezera magwiridwe antchito ndi mphamvu. Maphunziro opitilira amathandiza maukonde kugwiritsa ntchito ukadaulo wamakono kuphatikiza kuchulukitsa kwa mafunde kuti akwaniritse kukula kwakukulu.

Mapeto

Mukadziwa kusiyana pakati pa single-mode ndi multimode fiber, mudzakhala okonzeka bwino kupanga zisankho zanzeru pa zomwe netiweki yanu ikufuna. Single-mode fiber ndi yothandiza kwambiri polumikizana pa mtunda wautali komanso maulalo othamanga kwambiri, pomwe multimode fiber ndi yoyenera kwambiri pa mtunda waufupi komanso malo osamala bajeti. Mtundu uliwonse uli ndi zabwino zake. Sankhani mtundu womwe ungakwaniritse bwino zosowa zapadera za polojekiti yanu - kuyambira bajeti, kukula, mpaka zolinga zogwirira ntchito.

Kusankha kulikonse kumapereka mayankho odalirika komanso okonzeka mtsogolo ku ma network amakono. Kusankha yoyenera kumakupatsani mwayi wowonjezera magwiridwe antchito ndikuchepetsa kufunikira kwa zosintha zokwera mtengo mtsogolo. Kuyendetsa malo osungira deta amakampani, kusintha netiweki ya masukulu abizinesi kapena kukhazikitsa zomangamanga kuti zigwirizane ndi mwayi watsopano wamabizinesi? Zomangamanga zabwino Ulusi woyenera ungakhudze kwambiri zochitika zonsezi—m'njira yabwino! Kuti mupeze zotsatira zabwino, sankhani mogwirizana ndi zomwe mukufuna kukwaniritsa komanso kukula kwa netiweki yanu.

 

Mafunso Ofunsidwa Kawirikawiri

Kodi kusiyana kwakukulu pakati pa single-mode ndi multimode fiber ndi kotani?

Kusiyana kwakukulu ndi kukula kwa pakati. Ulusi wa single-mode uli ndi pakati kakang'ono (pafupifupi ma microns 8-10), komwe kumalola mawonekedwe amodzi owala, pomwe ulusi wa multimode uli ndi pakati lalikulu (ma microns 50-62.5) pamawonekedwe angapo owala. Izi zimakhudza kwambiri mtunda wawo ndi mphamvu zawo za bandwidth.

Ndi mtundu uti wa ulusi womwe uli bwino kwambiri potumiza uthenga patali?

Ulusi wa single-mode ndi wothandiza kwambiri potumiza uthenga patali. Ukadaulo uwu sunataye chizindikiro chilichonse ndipo umalola kuti bandwidth ikhale yayikulu kwambiri patali kwambiri. Zonsezi ndi chifukwa chake ndi zabwino kwambiri pa malo olumikizirana mauthenga ndi deta.

Kodi ulusi wa multimode ndi wotsika mtengo kuposa ulusi wa single-mode?

Mtundu wa ulusi ndi wofunika Inde, ulusi wa multimode nthawi zambiri umakhala wotsika mtengo. Zingwe ndi zida zogwirizana nazo, kuphatikizapo ma transceivers, ndizotsika mtengo poyerekeza ndi makina amtundu umodzi. Izi zimapangitsa kuti zikhale njira yotsika mtengo kwambiri yogwiritsira ntchito nthawi yochepa.

Kodi ndi zinthu ziti zomwe zimagwiritsidwa ntchito nthawi zambiri pa ulusi wa single-mode?

Ulusi wa single-mode ukupitilizabe kukhala ukadaulo wofunikira kwambiri pakulankhulana kwakutali komanso ma network a metro area. Umaonekera bwino kwambiri m'mapulogalamu apamwamba monga ma backbone a pa intaneti ndi malo osungira deta akuluakulu.

Kodi ulusi wa multimode ungathandizire kuthamanga kwa 10Gbps?

Inde, ulusi wa multimode ukhoza kuthandizira liwiro la 10Gbps, koma pa mtunda waufupi, nthawi zambiri mpaka mamita 1,000 ndi zingwe za OM3 kapena OM4 multimode.

Kodi ndingasankhe bwanji pakati pa single-mode ndi multimode fiber pa netiweki yanga?

Ganizirani za mtunda ndi zofunikira pa bandwidth ya netiweki yanu. Kawirikawiri, single-mode ndi yoyenera pa mtunda wautali kapena bandwidth yayikulu pomwe multimode imagwira ntchito pa kulumikizana kwaufupi komanso kotsika mtengo monga mkati mwa nyumba kapena sukulu.

Kodi ulusi wa single-mode ndi wabwino kwambiri kuti ukhale wokulirapo?

Inde, ulusi wa single-mode ndi wabwino kwambiri pakukula. Kutha kwawo kuthana ndi bandwidth yayikulu komanso mtunda wautali kumawapangitsa kukhala abwino kwambiri pakukonzanso ma netiweki mtsogolo komanso kufunikira kwatsopano kwa ma transmission othamanga kwambiri.
