Kodi fiber single-mode ndi multimode fiber ndi chiyani?

Singlemode fiber(Ulusi wamtundu umodzi), kuwala kumalowa muzitsulo pamtunda wina wa zochitika, ndipo kutulutsa kwathunthu kumachitika pakati pa ulusi ndi kuphimba Pamene m'mimba mwake ndi yaying'ono, kuwala kokha kumaloledwa kudutsa njira imodzi, yomwe Ndi imodzi - mode fiber; singlemode fiber; Ulusi wa Modal uli ndi pakatikati pa galasi lopyapyala, nthawi zambiri 8.5 kapena 9.5mm m'mimba mwake, ndipo imagwira ntchito pamafunde a 1310 ndi 1550 nm.

Multimode fiber ndifiberzomwe zimalola kutumiza njira zingapo zowongolera. Chigawo chapakati cha fiber multimode nthawi zambiri chimakhala 50mm / 62,5mm. Chifukwa cha kukula kwakukulu kwapakati pa fiber multimode, kuwala kumatha kufalitsidwa m'njira zosiyanasiyana mu fiber imodzi. Mafunde amtundu wa multimode ndi 850nm ndi 1300nm, motsatana. Palinso mulingo watsopano wa fiber multimode wotchedwa WBMMF (wideband multimode fiber), womwe umagwiritsa ntchito mafunde apakati pa 850nm ndi 953nm.

Ulusi wamtundu umodzi ndi ulusi wa multimode, zonse zokhala ndi mainchesi 125mm.
