Konjiniyela benethiwekhi, cishe akuyona into engaziwa kuboI-SFPechwebeni, sivame kushintsha, imojuli ye-optical,umzila, imishini yenethiwekhi yokuguqula imidiya yabona ukuba khona kwayo, kodwa kusenabasebenzisi abathile abangayiqondi kahleI-SFPport, futhi ubeke phambili uchungechunge lwezinkinga, njengokuthi, yini ukusetshenziswaI-SFPitheku,
Ingabe iI-SFPport an optical fibre port, canI-SFPport turn RJ 45, njll. Leli phepha lizogxila ekuphenduleni imibuzo embalwa ekhathazwa kakhulu abasebenzisi.
Yini iI-SFPitheku? Ingabe i-fiber outlet? Uyini umsebenzi?
I-SFPichweba liwukuxhumana ukuze kuzuzwe ukuguqulwa kwesignali ye-gigabit photoelectric, umsebenzi wayo oyinhloko owokuguqula isignali nokudluliswa kwedatha, izimbobo zayo zihlangabezana nezindinganiso ze-IEEE 802.3ab (ezifana ne-1000 BASE-T), izinga eliphezulu lokudlulisela elifika ku-1000 Mbps (ezinyeshintshaI-SFPamachweba asekela i-100 / 1000Mbps eguquguqukayo), ngakho-ke ibizwa nangokuthi i-gigabit fiber port.
Yiziphi izinzuzo ze-I-SFPamachweba?Iziphi izisetshenziswa zenethiwekhi ezivame ukusetshenziswa?
I-SFPichweba lingelesixhumi esibonakalayo se-hot-plug I / O (isho isikhombimsebenzisi sokufaka / sokuphumayo), esinokuguquguquka okuqinile, esilungele amadivaysi enethiwekhi ahlukahlukene, njengeI-SFPi-optical module, i-Gigabitshintsha, njll., ingashintshwa nge-1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX noma 1000 BASE-BX 10-D / U port. Ngaphezu kwalokho, i-I-SFPichweba liyahambisana phansi futhi lisekela i-10/100/1000Mbps. Ngamafuphi, i-I-SFPitheku linezinzuzo ezine ezinkulu:
● Isekela ipulaki eshisayo, inganciphisa isikhathi sokuphatha ukufakwa nokulungiswa;
● Ichweba liyavumelana nezimo;
● Idizayini eqinile ithuthukisa ukwethembeka;
● Ihambisana ne-10 / 100 / 1000Mbps.
1. II-SFPichweba leI-SFPi-optical module
I-SFPi-optical module iyisisetshenziswa esibonakalayo esiguqula amasiginali kagesi wegigabit abe amasignali optical. Kuyimojula edidiyelwe ye-gigabit optical transceiver edidiyelwe esezingeni lemboni. Iziphetho ezimbili zeI-SFPimojula ye-optical: isiphetho esisodwaI-SFPport, efakwe kakhulu phakathishintsha, umzila, isiguquli semidiya nezinye izisetshenziswa zenethiwekhi zokuguqula amasignali kagesi abe amasignali okukhanya ukuze adluliselwe; omunye umkhawulo uyisixhumi esibonakalayo se-LC noma isixhumi esibonakalayo se-RJ 45, esisetshenziswa kakhulu ukuxhuma i-fiber optical noma intambo yenethiwekhi ukuze kudluliselwe idatha.
2. II-SFPichweba le-gigabitshintsha
I-GigabitshintshaI-SFPichweba lingaxhunywa ezinhlotsheni ezahlukene zefiber (njengemodi eyodwa kanye ne-multimode fibre) kanye ne-jumper yenethiwekhi (efana ne-Cat5e ne-Cat6) ukuze kwandiswe umsebenzi wokushintsha wenethiwekhi yonke, kodwa i-gigabitshintshaI-SFPimbobo ngaphambi kokusetshenziswa kumele iqale ifakweI-SFPoptical module, bese usebenzisa i-fiber jumper kanye ne-network jumper yokudlulisa idatha. Wonke amaswishi ebhizinisi emakethe namuhla anamabili okungenaniI-SFPamachweba angakha ama-topology enethiwekhi ye-annular noma yenkanyezi phakathi kwezakhiwo ezahlukene, izitezi noma izindawo ngokusebenzisa izintambo ezifana namafiber optical kanye nama-jumper enethiwekhi.
Uyini umehluko phakathiI-SFPichweba kanye nechweba le-RJ 45?
Nakuba i-I-SFPport kanye nechweba le-RJ 45 zonke zinezinga eliphezulu lokudlulisa elingu-1000Mbps, kukhona umehluko phakathi kwazo.
1. Izinhlelo zokusebenza ezahlukene
Ngokwesibonelo, iI-SFPechwebenishintshaidinga ukuhambisanaI-SFPimojula ye-optical nokusebenzisa i-fiber jumper ukubona ukudluliswa kwedatha; kanye nechweba le-RJ 45 ku-shintshaingabona ukudluliswa kwedatha ngokuqondile ngekhebula lenethiwekhi.
2. Ibanga lokudlulisela lihlukile
Imbobo ye-RJ 45 ikakhulukazi yenza ukudluliswa kwedatha ngekhebula lenethiwekhi, ibanga eliphezulu lokudlulisela lekhebula lenethiwekhi liyi-100 m, kuyilaphoI-SFPport idinga ukusebenzisa i-I-SFPi-optical module yokuxhuma ku-optical fiber jumper ukuze idluliselwe, futhi ibanga layo eliphezulu lokudlulisela liyibanga eliphezulu lokudluliselaI-SFPoptical module, okungukuthi, 160 amamitha.
I-SFPizimbobo zingafakwa kuzoOLTfuthishintshaimishini. I-Shenzhen HDV Phoelectron Technology Co., Ltd. ingumkhiqizi wemishini yenethiwekhi eneOLTuchungechunge kanyeshintshauchungechunge. Ngasikhathi sinye, ineqembu eliqinile lehadiwe nesoftware kanye nethimba langaphambi kokuthengisa kanye nelemva kokuthengisa, elinganikeza isevisi engcono kakhulu kumakhasimende.
