1.optical fiber core structure 1) Core: high refractive index, yomwe imagwiritsidwa ntchito potumiza kuwala;2) Kuyika: cholozera chocheperako, kupanga mawonekedwe owoneka bwino ndi pachimake;3) Wosanjikiza woteteza: amateteza kuwala kwa fiber.2.Single-mode ndi multi-mode Njira imodzi yokha ya kuwala ingathe kufalitsidwa ....

Optical fiber ndi chinthu chofunikira kwambiri pazaka zamasiku ano zama network, koma kodi mumamvetsetsadi fiber fiber?Kodi njira zolumikizirana ndi fiber ndi ziti?Kodi pali kusiyana kotani pakati pa optical cable ndi optical fiber?Kodi ndizotheka kuti fiber isinthe zingwe zamkuwa kuchokera kunja?

Mapulojekiti apano ofooka akakumana ndi kufalikira kwa mtunda wautali, ma fiber optics amagwiritsidwa ntchito nthawi zambiri.Chifukwa kufala mtunda wa CHIKWANGWANI kuwala ndi yaitali kwambiri, ambiri, kufala mtunda wa single-mode CHIKWANGWANI ndi oposa 10 makilomita, ndi kufala mtunda wa Mipikisano mode CHIKWANGWANI c ...

Ndi kukhazikitsa kwa "Broadband China" ndi "Kufulumizitsa ndi kuchepetsa malipiro" njira, China a fixed burodibandi maukonde luso mosalekeza bwino;burodibandi ogwiritsa ntchito asintha kuchoka ku 10M ndi pansi kupita ku 50M / 100M / 200M, ndipo asintha kupita ku Gigabit;...

Kukula kwa ma modules opanda waya optical communication: 5G networks, 25G / 100G optical modules ndizomwe zikuchitika Kumayambiriro kwa 2000, 2G ndi 2.5G maukonde anali akumangidwa, ndipo kugwirizana kwa siteshoni yoyambira kunayamba kudula kuchokera ku zingwe zamkuwa kupita ku zingwe za kuwala.Poyamba, 1.25G SFP Optical modul ...

Masiku ano, intaneti ndi gawo lofunikira pa moyo wathu watsiku ndi tsiku.Kunena zowona, pali njira ziwiri zazikulu zomwe timagwiritsira ntchito intaneti: imodzi ndi kudzera pa data ya foni yam'manja;ina, nthawi zambiri, ndi kudzera pa Broadband kunyumba kapena kuntchito.Malinga ndi akatswiri, kupeza opanda zingwe ndi mawaya ac...
