SFP Kho Qhov Kho Kho Kho Mob

SFP chaw nres nkoj yog ib qho interface uas paub txog kev hloov pauv hluav taws xob thiab hluav taws xob hloov dua siab tshiab. Nws lub luag haujlwm tseem ceeb yog rau kev hloov dua siab tshiab thiab cov ntaub ntawv kis. Nws cov chaw nres nkoj tau ua tiav nrog IEEE 802.3Yog tus qauv (xws li 1000 MBPS tus nqi yuav ncav cuag 1/00} t), thiab nws tseem hu ua Gigamp Fiber chaw nres nkoj. SFP kho kho qhov muag yog ib qho kev hloov pauv uas hloov cov cim hluav taws xob rau hauv kev ntsuas hluav taws xob. Nws yog kev lag luam {{10} Txheem me me pluggable gigit optical Transcealical Module. Ob qho tag nrho ntawm SFP kho qhov muag transce, uas yog tsuas yog muab ntsaws rau hauv cov cuab yeej hluav taws xob los hloov cov cim hluav taws xob rau kev xa khoom; Lwm qhov kawg yog LC interface lossis RJ45 interface, uas yog feem ntau yog siv los txuas kho qhov muag fiber ntau lossis network cable kis.

SFP chaw nres nkoj yog kub - swappable i / o interface=(hais txog lub tswv yim / tso zis interface). Nws muaj qhov muaj zog hloov kho thiab yog tsim rau ntau yam kev siv network, thiab lwm yam} dua} dua, thiab lwm yam.} Ib qho ntxiv, SFP chaw nres nkoj rov qab tau tshaj thiab txhawb 10/100 / 1000mbps. Hauv ntej, SFP cov chaw nres nkoj muaj 4 qhov loj loj:

● Txhawb cov kub swapping kub, uas tuaj yeem txo kev teeb tsa, txij nkawm thiab lub sijhawm tswj;

Chaw ua hauj lwm yooj yim;

Rugged tsim kho kom muaj kev ntseeg tau;

● Tau tshaj 10/100 / 1000mbps.

Q: Dab tsi yog qhov txawv ntawm SFP chaw nres nkoj thiab RJ45 chaw nres nkoj?

Txawm hais tias qhov kev sib kis tau ntau tshaj plaws ntawm SFP chaw nres nkoj thiab RJ45 chaw nres nkoj yog ob qho tib si 1000mbps, muaj qee qhov sib txawv ntawm ob.

1. Cov ntawv thov sib txawv

Piv txwv li, SFP chaw nres nkoj ntawm tus hloov yuav tsum tau nruab qhov kev xav tau nruab nrog SFP Optical module thiab siv kho cov roj tsom iav kho kom zoo nkauj kom ua tiav cov ntaub ntawv kis; Thaum lub RJ45 chaw nres nkoj ntawm qhov hloov yuav ncaj qha ua tiav cov ntaub ntawv kis tau los ntawm network cable.

2. Txawv sib txawv

Lub RJ45 chaw nres nkoj tsuas yog xa cov ntaub ntawv los ntawm lub network cable, thiab nws qhov kev sib kis tau tshaj plaws yog qhov kis tau siab tshaj plaws ntawm lub network cable, uas yog 100 meters; Thaum lub chaw nres nkoj SFP yuav tsum muaj SFP Optical Transceer kom muaj kev sib kis tau rau kev sib kis tau zoo tshaj plaws yog qhov kev sib kis tau tshaj plaws ntawm SFP kho qhov muag. Qhov kev ncua deb yog 160 meters.

Q: Qhov sib txawv ntawm SFP, SFP +, SFP28, QSFP + thiab QSFP28

1. SFP

SFP yog cov tsiaj ntawv luv ntawm daim ntawv me me Pluggable. Nws tuaj yeem tsuas nkag siab raws li kev hloov kho tshiab ntawm GBIC. Nws ntim tsuas yog 1/2 ntawm GBIC module. Cov qauv tsim tau zoo tshaj qhov chaw nres nkoj ntom ntawm cov cuab yeej siv network. Qhov kis tau tus nqi ntawm SFP encapsulated optical modules suav nrog 155m, 1.25g, ntxiv rau hauv sonet / 100000

2. SFP +

SFP + muaj qhov zoo ib yam li SFP. Tus kis tus nqi ntawm SFP + Packaged Optical modules Muaj xws li 6G, 8G, thiab lwm yam khoom siv hluav taws xob, 10G DAC siab dua thiab 10G AOC nquag kho qhov muag. SFP + series cov khoom lag luam yog siv nyob rau hauv 10g (10GBase - sr)} SR)} SR) ethernet txuas hauv cov chaw teev.

3. SFP28

SFP28 yog ib qho kev txhim kho ntawm SFP + thiab muaj tib lub loj li SFP +, tab sis nws tuaj yeem pab txhawb ib qho {}} channel 25GB / s tus nqi. SFP28 muab kev daws teeb meem zoo rau 10g-}}}}} 1g-100g network hloov zuj zus los ua kom tau kev nce qib txuas ntxiv ntawm cov ntaub ntawv txuas ntxiv tom ntej.

4. QSFP +

QSFP + ntim khoom tuaj yeem txhawb nqa 4-channel sib kis tau tib lub sijhawm, nrog cov ntaub ntawv tus nqi ntawm 10Gbit / s rau txhua lub channel thiab 40gbps kis tus nqi ntawm 4 raws. Piv nrog SFP +, tus mob kis ntawm QSFP + ModiCal modules tuaj yeem muaj txog plaub zaug ntawm SFP + Kho qhov muag. QSFP + Modecical Modules tuaj yeem siv ncaj qha thaum mus rau 40g tes hauj lwm, yog li cov nqi txuag tau zoo thaum nce chaw nres nkoj ntom ntom.

5. QSFP28

Tus QSFP28 ntim hom yog tsim los ua kom tau raws li qhov xav tau ntawm 100g daim ntawv thov. Nws tuaj yeem pab txhawb 4-channel sib kis tau tib lub sijhawm, nrog cov ntaub ntawv ntawm 25Gbit / s rau txhua lub channel, thiab 100GBps kis tus nqi ntawm 4 teev. Nws tuaj yeem ua tau raws daim ntawv thov yuav tsum muaj ntawm 100g ethernet (4 × 25Gbps) thiab EDR Infiniband.
