Amanye amakhasimende awakwazi ukwenza isiqiniseko sokuthi yiluphi uhlobo lwefayibha ye-multimode okudingeka alukhethe.Ngezansi kunemininingwane yezinhlobo ezahlukene zesithenjwa sakho.
Kunezigaba ezihlukene zekhebula lefayibha yengilazi enenkomba enenkomba, okuhlanganisa izintambo ezingu-OM1, OM2, OM3 kanye ne-OM4 (i-OM imele i-optical multi-mode).
I-OM1 icacisa ikhebuli engu-62.5-micron futhi i-OM2 icacisa ikhebuli engu-50-micron.Lezi zivame ukusetshenziswa ezindaweni zokusebenza zokufinyelela okufushane amanethiwekhi we-1Gb/s.Kodwa ikhebula le-OM1 ne-OM2 awafanele amanethiwekhi anamuhla anesivinini esiphezulu.
I-OM3 ne-OM4 yomibili i-laser-optimized multimode fiber (LOMMF) futhi yathuthukiswa ukuze ikwazi ukuthwala inethiwekhi ye-fiber optic esheshayo njenge-10, 40, kanye ne-100 Gbps.Zombili zenzelwe ukusetshenziswa nama-850-nm VCSELS (ama-laser aphuma phezulu embobeni amile) futhi anezishebo ze-aqua.
I-OM3 icacisa ikhebuli engu-850-nm laser-optimized 50-micron enomkhawulokudonsa osebenzayo we-modal (EMB) ongu-2000 MHz/km.Ingakwazi ukusekela amabanga okuxhumanisa angu-10-Gbps kufika kumamitha angu-300.I-OM4 icacisa ikhebula yomkhawulokudonsa ophezulu engu-850-nm laser-optimized 50-micron bandwidth yomkhawulokudonsa osebenzayo we-modal ongu-4700 MHz/km.Ingakwazi ukusekela amabanga okuxhumanisa angu-10-Gbps amamitha angu-550.Amabanga angu-100 Gbps angamamitha angu-100 namamitha angu-150, ngokulandelana.
