Pali mitundu yosiyanasiyana ya chingwe cha fiber optic.Mitundu ina imakhala ya single-mode, ndipo ina ndi multimode.Multimode ulusi amafotokozedwa ndi pachimake ndi cladding diameters.Nthawi zambiri makulidwe a fiber multimode ndi 50/125 µm kapena 62.5/125 µm.Pakali pano, pali mitundu inayi ya ulusi wamitundumitundu: OM1, OM2, OM3, OM4 ndi OM5.Zilembo "OM" zimayimira optical multimode.Mtundu uliwonse wa iwo uli ndi makhalidwe osiyanasiyana.
Standard
"OM" iliyonse ili ndi zofunikira zochepa za Modal Bandwidth (MBW).OM1, OM2, ndi OM3 CHIKWANGWANI zimatsimikiziridwa ndi muyezo wa ISO 11801, womwe umachokera ku bandwidth ya modal ya fiber multimode.Mu Ogasiti 2009, TIA/EIA idavomereza ndikutulutsa 492AAAD, yomwe imatanthawuza machitidwe a OM4.Ngakhale adapanga zilembo zoyambirira za "OM", IEC sinatulutsebe muyezo wovomerezeka womwe pamapeto pake udzalembedwa ngati mtundu wa fiber A1a.3 mu IEC 60793-2-10.
Zofotokozera
● Chingwe cha OM1 nthawi zambiri chimabwera ndi jekete ya lalanje ndipo chimakhala ndi mainchesi 62.5 (µm).Imatha kuthandizira 10 Gigabit Ethernet kutalika kwa 33 metres.Imagwiritsidwa ntchito kwambiri pamapulogalamu a 100 Megabit Ethernet.
● OM2 ilinso ndi jekete la mtundu walanje.Kukula kwake kwakukulu ndi 50µm m'malo mwa 62.5µm.Imathandizira 10 Gigabit Ethernet kutalika mpaka 82 metres koma imagwiritsidwa ntchito kwambiri pamapulogalamu a 1 Gigabit Ethernet.
● Fibre ya OM3 ili ndi jekete la mtundu wa aqua.Monga OM2, kukula kwake kwakukulu ndi 50µm.Imathandizira 10 Gigabit Ethernet kutalika mpaka 300 metres.Kupatulapo OM3 imatha kuthandizira 40 Gigabit ndi 100 Gigabit Ethernet mpaka 100 metres.10 Gigabit Ethernet ndiyomwe imagwiritsidwa ntchito kwambiri.
● OM4 ilinso ndi jekete la mtundu wa aqua.Ndikusintha kwina kwa OM3.Imagwiritsanso ntchito 50µm core koma imathandizira 10 Gigabit Ethernet kutalika kwa 550 metres ndipo imathandizira 100 Gigabit Ethernet kutalika mpaka 150 metres.
● OM5 fiber, yomwe imadziwikanso kuti WBMMF (wideband multimode fiber), ndi mtundu watsopano wa fiber multimode, ndipo imagwirizana kumbuyo ndi OM4.Ili ndi kukula kofanana ndi OM2, OM3, ndi OM4.Mtundu wa jekete ya OM5 fiber idasankhidwa ngati laimu wobiriwira.Zapangidwa ndikufotokozedwa kuti zithandizire njira zosachepera zinayi za WDM pa liwiro lochepera la 28Gbps panjira kudzera pawindo la 850-953 nm.Zambiri zitha kupezeka pa: Zinthu Zitatu Zovuta Kwambiri pa OM5 Fiber Optic Cable
Diameter: Dera lapakati la OM1 ndi 62.5 µm, komabe, pakati pa OM2, OM3 ndi OM4 ndi 50 µm.

Momwe mungasankhire Multimode Fiber?
Ulusi wa Multimode umatha kutumiza mtunda wosiyanasiyana pamlingo wosiyanasiyana wa data.Mukhoza kusankha yoyenerera kwambiri malinga ndi ntchito yanu yeniyeni.Kuyerekeza kwapamtunda kwautali wa multimode fiber pamlingo wosiyana wa data kumafotokozedwa pansipa.
