Mtunda wotumizira wa fiber single-mode: 64-channel transmission ya 40G Ethernet ikhoza kukhala yaitali ma 2,840 mailosi pa chingwe chamtundu umodzi.Chingwe cha single mode chimapangidwa makamaka ndi pachimake, chotchingira ndi nsanjika zokutira. Pachimake chimapangidwa ndi zinthu zowonekera kwambiri. Chophimbacho chimakhala ndi index yocheperako pang'ono kuposa pachimake, zomwe zimapangitsa kuti pakhale mawonekedwe owoneka bwino omwe amalola ambiri. wa magetsi amagetsi kuti atsekedwe mu core.The ❖ kuyanika amachita kuteteza CHIKWANGWANI chimatetezedwa ku chinyezi ndi makina abrasion, pamene kuwonjezera kusinthasintha kwa CHIKWANGWANI.Kunja kwa chophimba chophimba, jekete lapulasitiki nthawi zambiri limawonjezeredwa.
Kodi pali kusiyana kotani pakati pa single mode fiber ndi multimode fiber?
Kusiyana kwa refractive index: Ulusi wamtundu umodzi umagwiritsa ntchito mbiri ya sitepe.Chifukwa chake, ulusi wa quartz utha kugwiritsanso ntchito ulusi wa multimode step index, multimode graded index fibers, ndi single mode step index ulusi.Mitundu itatu.
Kusiyanitsa kwa njira yopatsirana: fiber yamtundu umodzi imangotumiza njira imodzi yokhayokha pamlingo wopatsidwa ntchito, ndipo fiber multimode imatha kutumiza njira zingapo. Kuwonetseredwa kwathunthu pamawonekedwe a sing'anga, mafunde amagetsi amatsekeka pakati, omwe amatchedwa mafunde owongolera kapena motsogozedwa.Pamafunde operekedwa motsogozedwa ndi kutalika kwa magwiridwe antchito, pali zochitika zosiyanasiyana zomwe zimakwaniritsa mawonekedwe athunthu, zomwe zimatchedwa mitundu yosiyanasiyana ya mafunde owongolera.Amagawidwa mu multimode CHIKWANGWANI ndi single mode CHIKWANGWANI mumalowedwe kufala.
Kusiyana kwa mtunda wopatsirana: mtunda wotumizira ndi bandwidth yotumizira ya fiber single-mode mwachiwonekere chifukwa cha multimode fiber.Ngati mtunda wopatsirana ndi waukulu kuposa 5 km, chizindikiro chachikulu cha gulu lalikulu chimaperekedwa kwa nthawi yayitali kuti musankhe fiber imodzi yokha. transmitter/receiver imafuna kuwala kwa laser kuposa njira imodzi.Ndizotsika mtengo kwambiri.
Kusiyanitsa kwa kutalika kwa mawonekedwe a fiber transmission: single-mode fiber imakhala ndi mainchesi ang'onoang'ono ndipo imatha kufalitsidwa munjira imodzi yokha pamlingo woperekedwa, wokhala ndi bandwidth yotumizira komanso mphamvu yayikulu yotumizira.Multimode CHIKWANGWANI ndi kuwala CHIKWANGWANI chomwe chimatha kufalikira nthawi imodzi m'njira zingapo pamlingo womwe wapatsidwa.Multimode CHIKWANGWANI chili ndi ntchito yoyipa yopatsirana kuposa ulusi umodzi wamtundu umodzi.
