Injineerada shabakadaha, malaha kuma cusbaSFPDekedda, waxaan inta badan ku jira beddelka, module indhaha, router, qalabka shabakada beddelka warbaahinta arkay jiritaanka, laakiin weli waxaa jira qaar ka mid ah dadka isticmaala ma si dhab ah u fahmaanSFPdekedda, oo ay soo bandhigaan dhibaatooyin taxane ah, sida, maxaa faa'iido lehSFPdekedda,
waa kaSFPdekedda dekedda fiber optic ah, kartaanSFPport turn RJ 45, iwm. Warqadani waxay diiradda saari doontaa ka jawaabida su'aalo dhowr ah oo ay aadka uga walaacsan yihiin isticmaalayaashu.
Waa maxaySFPdekedda?Ma fiber-ka-soo-baxa?Waa maxay shaqadu?
SFPdekeddu waa is-dhexgal si loo gaadho beddelka signalka sawir-qaadista ee gigabit, shaqadeeda ugu weyni waa beddelka calaamadaha iyo gudbinta xogta, dekedeedu waxay la kulmaan heerarka IEEE 802.3ab (sida 1000 BASE-T), heerka ugu sarreeya ee gudbinta ilaa 1000 MbpsSFPdekedaha waxay taageeraan 100/1000Mbps laqabsiga), sidaa darteed waxa kale oo loo yaqaan deked fiber gigabit ah.
Waa maxay faa'iidooyinka ku jiraSFPWaa kuwee aaladaha shabakadeed ee inta badan la isticmaalo?
SFPdekeddu waxay iska leedahay is-dhexgalka kulul ee I / O (waxaa loola jeedaa interface-gelinta wax-soo-saarka), oo leh dabacsanaan xooggan, oo ku habboon aaladaha shabakadda ee kala duwan, sidaSFPmodule indhaha, Gigabit beddelka, iwm, waxaa lagu beddeli karaa 1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX ama 1000 BASE-BX 10-D / U dekedda.Intaa waxaa dheer,SFPdekeddu hoos bay u soconaysaa waxayna taageertaa 10/100/1000Mbps.Marka la soo koobo, theSFPdekeddu waxay leedahay afar faa'iidooyin oo waaweyn:
● Taageerada kululeeyaha kulul, waxay yarayn kartaa rakibidda iyo maareynta waqtiga;
● Dekeddu waa dabacsan tahay;
● Naqshadaynta adag waxay kor u qaadaysaa isku halaynta;
● La jaan qaada 10/100/1000Mbps.
1. TheSFPdekedda eeSFPmodule indhaha
SFPmodule indhaha waa qalab interface ah oo u beddela calaamadaha korantada gigabit ee calaamadaha indhaha.Waa halbeegga warshadaha yar iyo pluggable gigabit transceiver module isku dhafan.Laba daraf ooSFPmodule indhaha: hal dhamaadka waaSFPdekedda, inta badan la geliyo beddelka, router, beddelaha warbaahinta iyo aaladaha shabakadaha kale si loogu beddelo calaamadaha korantada calaamadaha indhaha ee gudbinta;dhamaadka kale waa LC interface ama RJ 45 interface, kaas oo inta badan loo isticmaalo in lagu xiro fiber indhaha ama cable network gudbinta xogta.
2. TheSFPdekedda Gigabit beddelka
Gigabit beddelkaSFPdekedda waxaa lagu xidhi karaa noocyo kala duwan oo fiber ah (sida hal hab iyo multimode fiber) iyo jumper network (sida Cat5e iyo Cat6) si loo ballaariyo shaqada beddelka ee shabakadda oo dhan, laakiin gigabit beddelo.SFPdekedda ka hor inta aan la isticmaalin waa in marka hore la geliyoSFPmodule indhaha, ka dibna isticmaal jumper fiber iyo jumper network gudbinta xogta.Dhammaan shirkadaha ganacsiga ee suuqa maanta waxay leeyihiin ugu yaraan labaSFPdekado dhisi kara shabakad sannadle ah ama xiddigle ah oo u dhexeeya dhismayaal kala duwan, sagxadaha ama meelaha iyada oo loo marayo fiilooyinka sida fiilooyinka indhaha iyo boodayaasha shabakadda.
Waa maxay farqiga u dhexeeyaSFPdekedda iyo dekedda RJ 45?
Inkastoo aySFPdekedda iyo dekedda RJ 45 dhamaantood waxay leeyihiin xadiga gudbinta ugu badan ee 1000Mbps, waxaa jira farqi u dhexeeya iyaga.
1. Codsiyo kala duwan
Tusaale ahaan, theSFPDekadda daaradda shisheeyaha waxa ay u baahan tahay in la is waafajiyoSFPmodule indhaha iyo isticmaalka jumper fiber si loo xaqiijiyo gudbinta xogta;iyo dekedda RJ 45 ee daaran waxay xaqiiqsan kartaa gudbinta xogta si toos ah iyada oo loo marayo fiilada shabakadda.
2. Fogaanta gudbintu way ka duwan tahay
Dekedda RJ 45 waxay inta badan ku shaqeysaa gudbinta xogta iyada oo loo marayo fiilada shabakadda, masaafada ugu badan ee gudbinta fiilada shabakadu waa 100 m, halkaSFPdekeddu waxay u baahan tahay inay isticmaashoSFPmodule indhaha si ay ugu xidhmaan jumper fiber indhaha ee gudbinta, iyo fogaanta gudbinta ugu badan waa fogaanta gudbinta ugu badan ee ahSFPmodule indhaha, taas oo ah, 160 mitir.
SFPdekedaha waxaa lagu dabaqi karaaOLToo beddelo qalabka.Shenzhen HDV Phoelectron Technology Co., Ltd. waa soo saaraha qalabka shabakada lehOLTtaxane iyo beddelo taxane.Isla mar ahaantaana, waxay leedahay koox adag oo hardware iyo software iyo iibka ka hor iyo kooxda iibka ka dib, kuwaas oo siin kara adeegga ugu fiican ee macaamiisha.
