Kunezinhlobo ezahlukene zekhebula le-fiber optic.Ezinye izinhlobo ziyimodi eyodwa, kanti ezinye ziyi-multimode.Imicu ye-Multimode ichazwa ngamadayamitha awo ayisisekelo kanye ne-cladding.Ngokuvamile ububanzi befayibha ye-multimode kungaba ngu-50/125 µm noma u-62.5/125 µm.Njengamanje, kunezinhlobo ezine zemicu yamamodi amaningi: OM1, OM2, OM3, OM4 kanye ne-OM5.Izinhlamvu “OM” zimelela i-optical multimode.Uhlobo ngalunye lwazo lunezici ezihlukile.
Okujwayelekile
I-"OM" ngayinye inesidingo esincane se-Modal Bandwidth (MBW).I-OM1, i-OM2, ne-OM3 fiber inqunywa izinga le-ISO 11801, elisekelwe kumkhawulokudonsa we-modal we-multimode fiber.Ngo-Agasti ka-2009, i-TIA/EIA yagunyaza futhi yakhulula i-492AAAD, echaza indlela yokusebenza ye-OM4.Ngenkathi bethuthukisa amagama okuqala e-“OM”, i-IEC ayikakhiphi izinga elilinganayo eligunyaziwe elizogcina libhalwe njengohlobo lwefayibha A1a.3 ku-IEC 60793-2-10.
Imininingwane
● Ikhebuli ye-OM1 ngokuvamile ifika nejazi eliwolintshi futhi inosayizi omaphakathi ongu-62.5 micrometers (µm).Ingakwazi ukusekela i-10 Gigabit Ethernet ngobude obufika kumamitha angama-33.Isetshenziswa kakhulu ezinhlelweni ze-100 Megabit Ethernet.
● I-OM2 iphinde ibe nombala wejakhethi ophakanyisiwe owolintshi.Usayizi wayo oyinhloko ngu-50µm esikhundleni sika-62.5µm.Isekela i-10 Gigabit Ethernet ngobude obufika kumamitha angu-82 kodwa ivame ukusetshenziselwa izinhlelo zokusebenza ze-1 Gigabit Ethernet.
● I-OM3 fiber inombala wejakhethi ophakanyisiwe we-aqua.Njenge-OM2, usayizi wayo oyinhloko ngu-50µm.Isekela i-10 Gigabit Ethernet ngobude obufika kumamitha angama-300.Ngaphandle kwe-OM3 iyakwazi ukusekela i-40 Gigabit kanye ne-100 Gigabit Ethernet kufika kumamitha ayi-100.I-10 Gigabit Ethernet ukusetshenziswa kwayo okuvame kakhulu.
● I-OM4 iphinde ibe nombala wejakhethi ophakanyisiwe we-aqua.Kungukuthuthuka okwengeziwe ku-OM3.Iphinde isebenzisa i-50µm core kodwa isekela i-10 Gigabit Ethernet ngobude obufika kumamitha angu-550 futhi isekela i-100 Gigabit Ethernet ngobude obufika kumamitha angu-150.
● I-OM5 fiber, eyaziwa nangokuthi i-WBMMF (i-wideband multimode fiber), iwuhlobo olusha kakhulu lwefayibha ye-multimode, futhi ibuyela emuva iyahambisana ne-OM4.Inosayizi ofanayo oyisisekelo njengo-OM2, OM3, no-OM4.Umbala wejakhethi yefayibha ye-OM5 ukhethwe njengoluhlaza okotshani.Iklanyelwe futhi icaciswe ukusekela okungenani iziteshi ezine ze-WDM ngesivinini esincane esingu-28Gbps ngesiteshi ngasinye ngefasitela elingu-850-953 nm.Imininingwane eyengeziwe ingatholakala ku-: Three Critical Focuses on OM5 Fiber Optic Cable
Ububanzi: Ububanzi obuyingqikithi be-OM1 bungu-62.5 µm, nokho, ububanzi obuyisisekelo be-OM2, OM3 kanye ne-OM4 bungu-50 µm.
