Kukho iintlobo ezahlukeneyo zentambo yefiber optic.Ezinye iintlobo zendlela enye, kwaye ezinye iindidi ziyi-multimode.Iifibers ze-Multimode zichazwa ngondoqo kunye ne-cladding diameters.Ngokuqhelekileyo i-diameter ye-multimode fiber ingaba yi-50/125 µm okanye yi-62.5/125 µm.Okwangoku, kukho iintlobo ezine zeentsinga ze-multi-mode: i-OM1, i-OM2, i-OM3, i-OM4 kunye ne-OM5.Oonobumba “OM” bamele i-optical multimode.Uhlobo ngalunye lwazo luneempawu ezahlukeneyo.
Umgangatho
I-"OM" nganye inomlinganiselo ophantsi we-Modal Bandwidth (MBW) efunekayo.I-OM1, i-OM2, kunye ne-OM3 ifayibha zichongwa ngumgangatho we-ISO 11801, osekelwe kwi-modal bandwidth ye-multimode fiber.Ngo-Agasti ka-2009, i-TIA/EIA yavuma yaza yakhupha i-492AAAD, echaza indlela yokusebenza ye-OM4.Ngelixa baphuhlise ukutyunjwa kwe-"OM", i-IEC ayikakhuphi umgangatho ovunyiweyo olinganayo oya kuthi ekugqibeleni ubhalwe njengohlobo lwefiber A1a.3 kwi-IEC 60793-2-10.
Iinkcukacha
● Intambo ye-OM1 idla ngokuza nebhatyi eorenji kwaye inobukhulu obungundoqo obuyi-62.5 micrometers (µm).Inokuxhasa i-10 Gigabit Ethernet ngobude ukuya kwi-33 yeemitha.Isetyenziswa kakhulu kwi-100 Megabit Ethernet izicelo.
● I-OM2 inombala webhatyi ecetyisiweyo orenji.Ubungakanani bayo obungundoqo yi-50µm endaweni ye-62.5µm.Ixhasa i-10 Gigabit Ethernet ngobude ukuya kwi-82 yeemitha kodwa isetyenziswa ngokuqhelekileyo kwizicelo ze-1 Gigabit Ethernet.
● Ifiber ye-OM3 inombala webhatyi ocetyisiweyo we-aqua.Njenge-OM2, ubungakanani bayo obuphambili yi-50µm.Ixhasa i-10 Gigabit Ethernet ubude ukuya kwi-300 yeemitha.Ngaphandle kwe-OM3 iyakwazi ukuxhasa i-40 Gigabit kunye ne-100 ye-Gigabit Ethernet ukuya kwi-100 yeemitha.I-10 Gigabit Ethernet yeyona nto isetyenziswa kakhulu.
● I-OM4 inombala webhatyi ecetyisiweyo ye-aqua.Luphuculo olongezelelweyo kwi-OM3.Ikwasebenzisa i-50µm engundoqo kodwa ixhasa i-10 Gigabit Ethernet kubude ukuya kuma-550 yeemitha kwaye ixhasa i-100 Gigabit Ethernet kubude ukuya kuthi ga kwi-150 yeemitha.
● I-OM5 fiber, eyaziwa ngokuba yi-WBMMF (i-wideband multimode fiber), luhlobo olutsha lwefayibha ye-multimode, kwaye ibuyela ngasemva iyahambelana ne-OM4.Inobukhulu obufanayo obungundoqo njenge-OM2, i-OM3, kunye ne-OM4.Umbala webhatyi yefiber ye-OM5 ukhethwe njengekalika eluhlaza.Yenzelwe kwaye ichazwe ukuxhasa ubuncinci iziteshi ezine ze-WDM kwisantya esincinci se-28Gbps ngeshaneli nganye ngefestile ye-850-953 nm.Iinkcukacha ezithe kratya zinokufumaneka apha: IiNgcaciso ezintathu eziBalulekileyo kwi-OM5 Fiber Optic Cable
Idayamitha: Idayimitha engundoqo ye-OM1 yi-62.5 µm, nangona kunjalo, idiameter engundoqo ye-OM2, i-OM3 kunye ne-OM4 yi-50 µm.
