Isidingo esikhulu sokukhuphuka komkhawulokudonsa sigqugquzele ukukhishwa kwezinga le-802.3z (IEEE) le-Gigabit Ethernet phezu kwe-fiber optical.Njengoba sonke sazi, amamojula we-1000BASE-LX transceiver angasebenza kuphela kumafayibha emodi eyodwa.Nokho, lokhu kungase kubangele inkinga uma inethiwekhi yefayibha ekhona isebenzisa imicu ye-multimode.Uma ifayibha yemodi eyodwa yethulwa ku-multimode fibre, kuzovela into eyaziwa ngokuthi Differential Mode Delay (DMD).Lo mphumela ungabangela ukuthi amasignali amaningi enziwe angase adide umamukeli futhi akhiqize amaphutha.Ukuze uxazulule le nkinga, intambo yesichibi semodi yokumisa iyadingeka.Kulesi sihloko, ulwazi oluthile lweizintambo zezichibi zokulungisa isimoizokwethulwa.
Iyini I-Mode Conditioning Patch Cord?
Intambo yokuchibiyela yemodi iyintambo ye-multimode eyi-duplex enobude obuncane befayibha yemodi eyodwa ekuqaleni kobude bokudlulisela.Umgomo oyisisekelo ngemuva kwentambo ukuthi uvula i-laser yakho engxenyeni encane ye-fiber yemodi eyodwa, bese omunye umkhawulo wefayibha yemodi eyodwa uhlanganiswe nengxenye ye-multimode yekhebula ne-core offset ephakathi nendawo ye-multimode. i-fiber.
Njengoba kuboniswe esithombeni
Leli phuzu le-offset lidala ukwethulwa okufana nokwethulwa okujwayelekile kwe-multimode ye-LED.Ngokusebenzisa i-offset phakathi kwe-fiber yemodi eyodwa kanye ne-multimode fibre, izintambo zezichibi zemodi yemodi ziqeda i-DMD kanye namasiginali amaningi avumela ukusetshenziswa kwe-1000BASE-LX phezu kwezinhlelo zekhebula ze-multimode fiber.Ngakho-ke, lezi zintambo ze-patch conditioning yemodi zivumela amakhasimende ukuthi athuthukise ubuchwepheshe babo behadiwe ngaphandle kokuthuthukiswa okumba eqolo kwesitshalo sabo sefayibha.
Amanye Amathiphu Lapho Usebenzisa I-Mode Conditioning Patch Cord
Ngemva kokufunda mayelana nolwazi oluthile lwezintambo zezichibi zokulungisa imodi, kodwa ingabe uyazi ukuthi zisetshenziswa kanjani?Khona-ke amanye amathiphu lapho usebenzisa izintambo zokumisa imodi azokwethulwa.
Izintambo zezichibi zemodi yemodi ngokuvamile zisetshenziswa ngababili.Okusho ukuthi uzodinga intambo yesichibi esilungisa isimo ekugcineni ngakunye ukuze uxhume okokusebenza embonini yekhebula.Ngakho-ke lezi zintambo zokubopha ngokuvamile zi-odwa ngezinombolo.Ungase ubone umuntu oda intambo yesichibi eyodwa kuphela, khona-ke ngokuvamile kungenxa yokuthi uyigcina njengesipele.
Uma imojula yakho ye-transceiver engu-1000BASE-LX ifakwe izixhumi ze-SC noma ze-LC, sicela uqiniseke ukuthi uxhuma umlenze ophuzi (imodi eyodwa) wekhebula ohlangothini lokudlulisa, nomlenze osawolintshi (i-multimode) ohlangothini lokwamukela lwamathuluzi. .Ukushintshaniswa kokudlulisa nokwamukela kungenziwa kuphela ohlangothini lwesikhungo sekhebula.
Izintambo zokuchibiyela zemodi zingaguqula imodi eyodwa kuphela ibe yimodi eningi.Uma ufuna ukuguqula i-multimode ibe yimodi eyodwa, kuzodingeka isiguquli semidiya.
Ngaphandle kwalokho, izintambo zezichibi zemodi yemodi zisetshenziswa ku-1300nm noma i-1310nm optical wavelength window, futhi akufanele isetshenziselwe iwindi le-wavelength elifushane elingu-850nm njenge-1000Base-SX.
Isiphetho
Kusuka embhalweni, siyazi ukuthi izintambo zokuvala izimo zemodi zithuthukisa kakhulu ikhwalithi yesiginali yedatha futhi zikhuphule ibanga lokudlulisela.Kodwa lapho uyisebenzisa, kukhona futhi amanye amathiphu okufanele agcinwe engqondweni.I-RAISEFIBER inikezela ngezintambo zokuchibiyela zemodi kuzo zonke izinhlobo nezinhlanganisela ze-SC, ST, MT-RJ kanye nezixhumi ze-LC fibre optic.Zonke izintambo zokuchibiyela imodi ye-RAISEFIBER zikukhwalithi ephezulu futhi ngentengo ephansi.
