Ekubeni i-OM1 kunye ne-OM2 iifayili azikwazi ukuxhasa ukuhanjiswa kwedatha ye-25Gbps kunye ne-40Gbps, i-OM3 kunye ne-OM4 yizona zikhetho eziphambili ze-multimode fibers ezixhasa i-25G, i-40G kunye ne-100G Ethernet.Nangona kunjalo, njengoko iimfuno ze-bandwidth zisanda, ixabiso leentambo ze-fiber optic ukuxhasa isizukulwana esilandelayo sokufuduka kwesantya se-Ethernet sinyuka kwaye siphezulu.Kulo mongo, i-OM5 ifayibha yazalwa ukwandisa inzuzo ye-multimode fiber kwiziko ledatha.
Imodeli yentambo yefiber optic yeMultimode:
I-OM3 yi-50um core diameter multimode fiber eyenziwe nge-laser ye-850nm.Kwi-10Gb / s Ethernet usebenzisa i-850nm VCSEL, umgama wokuhanjiswa kwefiber ungafikelela kwi-300m;I-OM4 yinguqu ephuculweyo ye-OM3, i-OM4 i-multimode fiber ilungiselela i-OM3 i-multimode fiber Ngenxa yokulibaziseka kwemodi yokwahlukana (i-DMD) eyenziwa ngexesha lokudluliselwa kwesantya esiphezulu, umgama wokuhanjiswa uphuculwe kakhulu, kwaye umgama wokuhanjiswa kwe-fiber optical ungafikelela kwi-550m.
Umahluko ophambili phakathi kwabo kukuba phantsi kwe-4700MHz-km, i-EMB ye-OM4 fiber ichazwe kuphela njenge-850 nm, ngelixa ixabiso le-OM5 EMB lichazwe njenge-850 nm kunye ne-953 nm, kwaye ixabiso kwi-850 nm likhulu kune-OM4.Ke ngoko, i-OM5 ifayibha ibonelela abasebenzisi ngemigama emide kunye neenketho ezininzi zefiber.Ukongeza, i-TIA ichonge i-lime eluhlaza njengombala webhatyi yentambo esemthethweni ye-OM5, ngelixa i-OM4 iyibhatyi yamanzi.I-OM4 yenzelwe i-10Gb / s, i-40Gb / s kunye ne-100Gb / s yokudluliselwa, kodwa i-OM5 yenzelwe i-40Gb / s kunye ne-100Gb / s yokudluliselwa, enokunciphisa inani leefayili ze-optical zokudluliselwa kwesantya esiphezulu.
Ukongezelela, i-OM5 inokuxhasa iziteshi ezine ze-SWDM, nganye yazo ithwala idatha ye-25G, kwaye isebenzisa i-multimode fibers optical fibers ukubonelela nge-100G Ethernet.Ukongeza, ihambelana ngokupheleleyo ne-OM3 kunye ne-OM4 fibers.I-OM5 ingasetyenziselwa ukufakwa kwiindawo ezahlukeneyo zenkampani emhlabeni jikelele, ukusuka kwiikhampasi ukuya kwizakhiwo ukuya kumaziko edatha.Ngamafutshane, i-OM5 fiber ingcono kune-OM4 ngokubhekiselele kumgama wothumelo, isantya kunye neendleko.
Inkcazo yemodeli yentambo yefiber optic ngokubanzi: Thatha imowudi engundoqo emine njengomzekelo, (4A1b yi62.5/125µm, 4A1 yi50/125µm).
