Njengoba i-OM1 ne-OM2 fibers ayikwazi ukusekela isivinini sokudlulisa idatha ye-25Gbps ne-40Gbps, i-OM3 ne-OM4 yizinqumo eziyinhloko zezintambo ze-multimode ezisekela i-25G, i-40G ne-100G Ethernet.Kodwa-ke, njengoba izidingo zomkhawulokudonsa zikhula, izindleko zezintambo ze-fiber optic zokusekela ukufuduka kwesivinini se-Ethernet yesizukulwane esilandelayo nazo ziya ngokuya zikhuphuka.Kulo mongo, i-OM5 fiber yazalelwa ukuze kwandiswe izinzuzo ze-multimode fiber esikhungweni sedatha.
Imodeli yekhebula ye-Multimode fibre optic:
I-OM3 iyi-50um core diameter multimode fiber eyenziwe nge-laser engu-850nm.Ku-10Gb / s Ethernet usebenzisa i-850nm VCSEL, ibanga lokudlulisa i-fiber lingafinyelela ku-300m;I-OM4 inguqulo ethuthukisiwe ye-OM3, i-OM4 i-multimode fiber ithuthukisa i-OM3 ye-multimode fiber Ngenxa yokubambezeleka kwemodi yokuhlukanisa (i-DMD) ekhiqizwa ngesikhathi sokudlulisa ngesivinini esikhulu, ibanga lokudlulisela liye lathuthukiswa kakhulu, futhi ibanga lokudlulisa i-fiber optical lingafinyelela ku-550m.
Umehluko oyinhloko phakathi kwazo ukuthi ngaphansi kuka-4700MHz-km, i-EMB ye-OM4 fiber icaciswa kuphela njenge-850 nm, kuyilapho inani le-OM5 EMB licaciswa njengo-850 nm no-953 nm, futhi inani eliku-850 nm likhulu kune-OM4.Ngakho-ke, i-OM5 fiber inikeza abasebenzisi amabanga amade kanye nezinketho zefayibha ezengeziwe.Ngaphezu kwalokho, i-TIA ikhethe umbala oluhlaza okotshani njengombala osemthethweni webhantshi lekhebula le-OM5, kuyilapho i-OM4 iyijakhethi yamanzi.I-OM4 yenzelwe ukudluliswa kwe-10Gb/s, 40Gb/s kanye ne-100Gb/s, kodwa i-OM5 yenzelwe ukudluliselwa kwe-40Gb/s kanye ne-100Gb/s, enganciphisa inani lemicu ye-optical yokudlulisela ngesivinini esikhulu.
Ngaphezu kwalokho, i-OM5 ingasekela iziteshi ezine ze-SWDM, ngayinye ephethe idatha ye-25G, futhi isebenzisa i-multimode optical fibers ukunikeza i-100G Ethernet.Ngaphezu kwalokho, ihambisana ngokugcwele ne-OM3 ne-OM4 fibers.I-OM5 ingasetshenziselwa ukufakwa ezindaweni ezihlukahlukene zezinkampani emhlabeni jikelele, kusukela emakhempasi kuya kumabhilidi kuya ezikhungweni zedatha.Ngamafuphi, i-OM5 fiber ingcono kune-OM4 ngokwebanga lokudlulisela, isivinini kanye nezindleko.
Incazelo evamile yemodeli yekhebula ye-fiber optic yemodi eminingi: Thatha isibonelo semodi eminingi yamamodi amaningi, (4A1b ingu-62.5/125µm, i-4A1 ingu-50/125µm).
