Menene OM1, OM2, OM3 da OM4 Fiber?

Daidaitawa

Kowane "OM" yana da mafi ƙarancin buƙatun Modal Bandwidth (MBW).OM1, OM2, da OM3 fiber an ƙaddara su ta hanyar ma'aunin ISO 11801, wanda ya dogara da yanayin bandwidth na fiber multimode.A cikin Agusta na 2009, TIA/EIA ta amince kuma ta fitar da 492AAAD, wanda ke bayyana ma'auni na aikin OM4.Yayin da suka ƙirƙira ainihin sunayen "OM", IEC ba ta riga ta fitar da ƙa'idar da aka yarda da ita ba wanda za a rubuta shi azaman nau'in fiber A1a.3 a cikin IEC 60793-2-10.

Ƙayyadaddun bayanai

● Kebul na OM1 yawanci yana zuwa tare da jaket na orange kuma yana da ainihin girman 62.5 micrometers (µm).Yana iya tallafawa 10 Gigabit Ethernet a tsayin mita 33.An fi amfani dashi don aikace-aikacen 100 Megabit Ethernet.

● OM2 kuma yana da shawarar launin jaket na lemu.Girman ainihin sa shine 50µm maimakon 62.5µm.Yana goyan bayan Gigabit Ethernet 10 a tsayi har zuwa mita 82 amma an fi amfani dashi don aikace-aikacen 1 Gigabit Ethernet.

● Fiber OM3 yana da launin jaket da aka ba da shawarar na ruwa.Kamar OM2, girman girman sa shine 50µm.Yana goyan bayan 10 Gigabit Ethernet a tsayi har zuwa mita 300.Bayan OM3 yana iya tallafawa 40 Gigabit da 100 Gigabit Ethernet har zuwa mita 100.10 Gigabit Ethernet shine mafi yawan amfani dashi.

● OM4 kuma yana da shawarar launin jaket na ruwa.Yana da ƙarin haɓakawa zuwa OM3.Hakanan yana amfani da core 50µm amma yana goyan bayan 10 Gigabit Ethernet a tsayin mita 550 kuma yana goyan bayan 100 Gigabit Ethernet a tsayi har zuwa mita 150.

● Fiber OM5, wanda kuma aka sani da WBMMF (fiber multimode fiber), shine sabon nau'in fiber multimode, kuma baya dacewa da OM4.Yana da girman asali iri ɗaya da OM2, OM3, da OM4.An zaɓi launi na jaket ɗin fiber OM5 azaman kore mai lemun tsami.An tsara shi kuma an ƙayyade shi don tallafawa aƙalla tashoshi na WDM guda huɗu a mafi ƙarancin saurin 28Gbps a kowace tashoshi ta taga 850-953 nm.Ana iya samun ƙarin cikakkun bayanai a: Hanyoyi masu mahimmanci guda uku akan OM5 Fiber Optic Cable

Diamita: Babban diamita na OM1 shine 62.5 µm, duk da haka, ainihin diamita na OM2, OM3 da OM4 shine 50 µm.
