Rau network engineers, xav tias tsis muaj neeg txawvSFPchaw nres nkoj, peb feem ntau nyob rau hauv lubhloov, optical module,router, media converter network cov cuab yeej pom lub hav zoov ntawm nws, tab sis tseem muaj qee cov neeg siv tsis tshua to taubSFPchaw nres nkoj, thiab muab tso rau ib tug series ntawm cov teeb meem, xws li, dab tsi yog sivSFPchaw nres nkoj,
Yog tusSFPchaw nres nkoj qhov chaw nres nkoj fiber ntau optical, tuaj yeemSFPchaw nres nkoj tig RJ 45, thiab lwm yam. Daim ntawv no yuav tsom rau kev teb ntau cov lus nug uas muaj kev txhawj xeeb tshaj plaws los ntawm cov neeg siv.
Dab tsi yog qhovSFPchaw nres nkoj? Puas yog lub qhov hluav taws xob fiber ntau? Lub luag haujlwm yog dab tsi?
SFPchaw nres nkoj yog ib qho kev sib txuas kom ua tiav gigabit photoelectric teeb liab hloov dua siab tshiab, nws lub luag haujlwm tseem ceeb yog rau kev hloov pauv cov teeb liab thiab cov ntaub ntawv xa mus, nws cov chaw nres nkoj tau raws li IEEE 802.3ab cov qauv (xws li 1000 BASE-T), qhov siab tshaj plaws kis tau tus mob mus txog 1000 Mbps (qeehloovSFPports txhawb 100 / 1000Mbps adaptive), yog li nws tseem hu ua gigabit fiber chaw nres nkoj.
Dab tsi yog qhov zoo ntawm covSFPports?Cov khoom siv network twg uas nquag siv?
SFPchaw nres nkoj belongs rau kub-plug I / O interface (hais txog cov tswv yim / tso zis interface), muaj zog yooj, haum rau ntau yam khoom siv hauv network, xws liSFPOptical module, Gigabithloov, thiab lwm yam, tuaj yeem hloov pauv nrog 1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX lossis 1000 BASE-BX 10-D / U chaw nres nkoj. Ntxiv rau, covSFPchaw nres nkoj yog downward tshaj thiab txhawb 10 / 100 / 1000Mbps. Hauv luv, lubSFPchaw nres nkoj muaj plaub qhov zoo:
● Txhawb nqa kub ntsaws, tuaj yeem txo qhov kev teeb tsa thiab kev tswj xyuas lub sijhawm;
● Qhov chaw nres nkoj yog hloov tau;
● Cov qauv tsim muaj zog txhawb kev ntseeg tau;
● Tau tshaj 10 / 100 / 1000Mbps.
1. CovSFPchaw nres nkojSFPkho qhov muag module
SFPoptical module yog ib qho khoom siv interface uas hloov gigabit hluav taws xob teeb liab rau hauv cov teeb liab optical. Nws yog kev lag luam tus qauv me me thiab pluggable gigabit optical transceiver integrated module. Ob kawg ntawmSFPoptical module: ib kawg yogSFPchaw nres nkoj, feem ntau tso rau hauvhloov, router, media converter thiab lwm yam khoom siv hauv network los hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag rau kev sib kis; Lwm qhov kawg yog LC interface lossis RJ 45 interface, uas yog siv los txuas cov fiber ntau optical lossis network cable rau cov ntaub ntawv xa mus.
2. CovSFPchaw nres nkoj ntawm gigabithloov
GigabithloovSFPchaw nres nkoj tuaj yeem txuas rau ntau hom fiber ntau (xws li ib hom thiab multimode fiber ntau) thiab network jumper (xws li Cat5e thiab Cat6) kom nthuav dav kev hloov pauv ntawm tag nrho cov network, tab sis gigabit.hloovSFPchaw nres nkoj ua ntej siv yuav tsum xub tsoSFPoptical module, thiab tom qab ntawd siv fiber ntau jumper thiab network jumper rau cov ntaub ntawv xa mus. Txhua lub lag luam hloov pauv ntawm kev ua lag luam niaj hnub no muaj tsawg kawg yog obSFPcov chaw nres nkoj uas tuaj yeem tsim cov annular lossis hnub qub network topologies ntawm cov tsev sib txawv, pem teb lossis thaj chaw los ntawm cov cables xws li optical fibers thiab network jumpers.
Dab tsi yog qhov txawv ntawmSFPchaw nres nkoj thiab RJ 45 chaw nres nkoj?
Txawm tias covSFPchaw nres nkoj thiab RJ 45 chaw nres nkoj txhua tus muaj qhov siab tshaj plaws ntawm 1000Mbps, muaj qee qhov sib txawv ntawm lawv.
1. Cov ntawv thov sib txawv
Piv txwv li, lubSFPport rauhloovyuav tsum tau muab piv nrogSFPoptical module thiab siv fiber ntau jumper kom paub cov ntaub ntawv xa mus; thiab RJ45 chaw nres nkoj ntawm lubhloovtuaj yeem paub cov ntaub ntawv xa ncaj qha los ntawm lub network cable.
2. Kev sib kis nrug sib txawv
RJ 45 chaw nres nkoj tsuas yog ua cov ntaub ntawv xa mus los ntawm kev sib txuas hauv network, qhov siab tshaj plaws kis tau tus mob ntawm lub network cable yog 100 m,SFPchaw nres nkoj yuav tsum tau siv lubSFPoptical module txuas mus rau optical fiber jumper rau kis tau tus mob, thiab nws qhov siab tshaj plaws kis tau tus mob deb yog qhov siab tshaj plaws kis tau tus mob nyob debSFPoptical module, uas yog, 160 meters.
SFPports tuaj yeem siv rauOLTthiabhloovkhoom siv. Shenzhen HDV Phoelectron Technology Co., LtdOLTseries thiabhloovseries. Nyob rau tib lub sijhawm, nws muaj pab pawg kho vajtse thiab software muaj zog thiab pab pawg muag khoom ua ntej thiab tom qab muag, uas tuaj yeem muab kev pabcuam zoo tshaj plaws rau cov neeg siv khoom.
