SFP + Transceiver txhim kho kev ceev

 

Kuv twb tau teeb tsa tes hauj lwm rau cov chaw teev cov ntaub ntawv txij li xyoo 2014, thiab ib qho uas tsis xav tsis thoob kuv yog tias muaj pes tsawg tus thawj tswj hwm tseem tsis tau txais qhov tsim nyogSFP + Transceivertuaj yeem ua rau lawv cov cuab yeej siv hluav taws xob. Lub lim tiam dhau los, Kuv muaj ib tus neeg tau yws yws txog bottlenecks hauv lawv chav server. Muab lawv khiav tawm txhua yam ntawm cov qub gigabence sib txuas. Ua siab ncaj? Uas yog li sim ua kom lub pas dej da nrog lub vaj teb.

 

Vim li cas koj lub network yeej xav tau kev txhim kho

 

Nov yog qhov tsis muaj leej twg qhia koj ntawm kev lag luam qhia: kev nrawm tsis yog hais txog bandwidth. Nws yog hais txog dab tsi tshwm sim thaum peb caug tus neeg sim nkag mus rau tib lub database ib txhij ntawm 9 teev sawv ntxov. Koj 1G kev txuas yuav zoo rau daim ntawv, tab sis tiag- ntiaj teb siv? Uas yog qhov twg a10G SFP + TransceiverUa rau qhov sib txawv ntawm "lub kaw lus qeeb hnub no" thiab ua tau tiag tiag ua haujlwm.

Kuv nco ntsoov mus xyuas ib nrab -} qhov chaw nyob loj hauv Austin peb lub xyoos rov qab. Lawv tus txiv neej tus txiv neej tau cog lus txhua yam tau khiav zoo. Tom qab ntawd peb txheeb xyuas qhov tseeb ntawm lub sijhawm thaum lub sij hawm Peak- Next} NW nyuam qhuav tsoo 40% ntawm qhov lawv yuav tsum tau txais. Swapped nyob rau hauv qee qhov tsim nyog 10g modules thiab cov kev tsis txaus siab nres. Ib yam li ntawd.

 

 

Cov flavors txawv rau cov xwm txheej sib txawv

 

Tsis yog txhua tusSFP + transceiversyog tsim sib npaug, thiab qhov ntawd yog qhov chaw tib neeg mess lawv yuav. Koj tau txais koj cov kev xaiv fiber ntau, koj cov kev xaiv tooj liab, thiab tom qab ntawd koj tau txais kev txiav txim siab deb uas tsis muaj leej twg piav qhia zoo.

Thaum tooj liab ua rau muaj kev nkag siab

Yog tias koj sib txuas cov khoom siv nyob rau hauv tib lub khib lossis tej zaum yog ib qho ntxiv mus, a10g tooj liab SFP transceiveryog tej zaum koj thawj koom ruam zoo tshaj plaws. Lawv kub {{- swappable, lawv tsis xav tau nyiaj fiber ntau, thiab kev coj ncaj ncees lawv ua rau tawg dua li kev xaiv fiber ntau dua li cov kev xaiv fiber ntau dua. Kuv tau pom cov thev naus laus zis ua cov khoom no thaum lub cev nyob (tsis txhob ua li ntawd, los ntawm txoj kev) thiab lawv tsuas yog ua haujlwm.

Kev ntes? Deb. Koj nyob nraum saib ntawm tej zaum 30 metres qhov siab tshaj plaws, qee zaum tsis tshua muaj nyob ntawm cov khoom zoo. Qhov twg yog qhov zoo rau feem ntau --}}}} hloov cov chav sib txuas, koj yuav tsum xav txawv.

Mus deb nrog fiber ntau

Uas yog qhov chaw koj xaiv tau muaj fiber ntau los hauv. A10GBase LR SFP transceiver{{0- Yog lub ntev- muaj cov ntaub ntawv sib txawv hla 10 km {} hom fiber ntau. Kaum tus kmileters! Kuv muaj ib tus neeg siv khoom nrog cov tuam tsev ntawm qhov xaus ntawm cov chaw lag luam. Peb siv cov no los txuas lawv cov ntaub ntawv cov ntaub ntawv tsis tas yuav cuam tshuam nrog nruab nrab hloov lossis rov ua dua.

Lub sijhawm luv -} ntau cov khoom, dab tsi uas lawv hu ua sr modules {}}}}-}}} kev sib txuas hauv tsev. Multi - hom fiber ntau txog li 300 meters. Feem ntau cov tuam txhab cov chaw ib puag ncig haum uas cov ntaub ntawv tshwj xeeb.

 

Dab tsi tiag tiag thaum koj yuav

 

Tus nqi nqe rau ntawm cov khoom txawv, thiab tsis yog ib txwm rau cov laj thawj zoo. Kuv tau sim cov modules generic uas ua tau ib yam nkaus li lub npe - Hom Tshuaj siv tau them peb npaug. Tab sis - Thiab qhov no yog qhov tseem ceeb - sib xyaw ua ke ntau dua li daim ntawv lo.

Kuaj koj lub tshuab ua lag luam xa cov npe tau sib raug zoo. Tiag, ua qhov no ua ntej xaj ib yam dab tsi. Kuv tau saib cov neeg yuav zoo txig zoo10GB SFP + TransceiverModules uas lawv cov chaw hloov tsis kam lees paub vim qee qhov firmware quirk. SuperMICRO, Cisco, dell - Lawv txhua tus muaj lawv nyiam.

Qhov tseeb - NTIAJ TEB TES TES

Xav paub yog tias koj cov teeb tam sim no xav tau kev hloov kho tshiab? Ntawm no yog qhov kuv ua: khiav IPERF kev sim thaum lub sijhawm ua haujlwm. Tsis yog thaum 2 teev sawv ntxov thaum tsis muaj leej twg siv lub network - thaum lub sij hawm tiag tiag kev siv. Yog tias koj pom pob ntawv ua tiav saud 0.1% lossis yog tias koj cov spikes trikes tau tsoo ob tus lej tsis tu ncua, koj tau txais teeb meem.

Qhov kub thiab txias nyeem ib yam nkaus thiab, tab sis tsis muaj leej twg pom lawv. Cov mekev hloov siabModules tau kub thaum lawv ua haujlwm nyuaj. Feem ntau yog nyob rau 70 degree, tab sis yog tias koj pom kub ua ntu zus dhau 60℃hauv kev ua haujlwm ib txwm, koj yuav tsum muaj kev ua haujlwm li qub, tsuas yog koj txoj kev ua haujlwm xav tau kev ua haujlwm lossis tus qauv sib tw.

 

 

Kev teeb tsa tsis nyuaj (tab sis tib neeg ua nws txoj kev ntawd)

 

Kuv tsis suav pes tsawg zaus uas kuv tau raug hu rau hauv "transceiver daws teeb meem" qhov twg yog ib tug neeg yuam kev lossis tsis zaum nws kom zoo. Tej yam no muaj cov kev taw qhia tshwj xeeb thiab lawv nyem thaum lawv tau raug.

Tsis tas li - Thiab qhov no zoo li pom tseeb tab sis thaj tsis yog- Saib puas paub meej tias koj tshem cov hmoov av kaus mom ua ntej sim txuas cov xaim hluav taws xob. Kuv tau pom qhov yuam kev ntawd ntau dua li kuv xav lees.

 

Dab tsi cov specs tsis qhia koj

 

Ntawm no yog ib yam dab tsi nthuav: kub siab rau txawv ntawm cov tuam ntxhab txawm tias cov specs zoo ib yam. Kuv khaws ib txhais tes ntawm cov xim sib txawv hauv kuv cov cuab yeej tshwj xeeb vim tias qee qhov siab siab {1} -} qhov chaw ib puag ncig zoo dua lwm tus. Lub chaw neeg rau zaub mov uas muaj qhov ua kom txias dua tshiab? Cov Modules Superules khaws cia ua haujlwm thaum lub hom phiaj uas tau pib cuam.

Kev noj fais fab yog lwm qhov zais hloov. Ntau tshaj plaws10G SFP transceiverModules rub nruab nrab ntawm 1 thiab 1.5 watts, tab sis kuv tau ntsuas qee qhov khob ntawm 2 watts. Tsis tau zoo li ntau kom txog thaum koj tau txais 48 Ports siab populated thiab koj lub pob nyem tau rub tawm ib qho ntxiv watts tsuas yog pub mis.

 

Txoj kev txhim kho tsis muaj leej twg tham txog

 

Koj lub zog hloov tau muaj 10eb ports - Lawv tsuas yog yuav tsis tau txais kev tsis lees paub lossis xiam oob qhab. Txheeb xyuas koj lub peev xwm hloov lub peev xwm ua ntej piv txwv tias koj xav tau txhua yam khoom tshiab. Kuv tau khaws cov neeg siv nyiaj kaum tawm txhiab los ntawm tsuas yog ua rau cov chaw nres nkoj uas twb muaj lawm thiab ntxiv cov qauv tsim nyog.

Thiab yog tias koj npaj ua ntej - uas koj yuav tsum tau - Saib xyuas kom paub tseeb dual {2} Taug kev lag luam. Ib tug zoo10G SFP + TransceiverYuav pib - sib cog lus rau 1g yog tias xav tau. Muab koj cov khoom siv tau thaum koj tab tom khiav sib xyaw - ceev cov chaw.

 

Qhov yuam kev uas kuv pom ntau zaus

 

Kev sib xyaw cov hom fiber ntau yog kuv qhov kev ntxhov siab. Ib qho -} hom transceivers nrog ntau- hom fiber, lossis lwm yam. Lawv tsis tau hloov tau yooj yim, thiab sim ua kom lawv ua haujlwm tsuas yog muab kev sib txuas lus rau koj sib txuas thiab lub taub hau {{{4 4} thawb cov kev sib ntsib daws teeb meem.

Cable bend radius yog lwm qhov. Fiber ntau cov kab ke tsis muaj kev cuam tshuam. Khoov lawv yooj yim heev thiab koj tua koj lub teeb liab zoo txawm tias qhov txuas nyob qis qis. Kuv tau pom tag nrho kev teeb tsa qhov twg ib tug neeg cable {{Khi} Khis} Khis telishing thiab xav tias vim li cas lawv qhov yuam kev tau dhau lub ru tsev.

 

 

Yav tom ntej - ua pov thawj (lossis tsawg kawg sim ua)

 

Saib, 10G zoo li sai tau tam sim no, tab sis tsib xyoos dhau los cov neeg tau hais tib yam txog tus cwj pwm. Qhov xwm zoo yog tias SFP + cov cuab yeej siv hluav taws xob tuaj yeem tswj cov tuaj tom ntej yog koj npaj txawj ntse. Koj cov nroj tsuag cable tshaj plaws -}} yog tias koj txhim kho fiber ntau tam sim no, ua kom nws zoo fiber ntau. OM3 tsawg kawg, om4 yog tias koj tuaj yeem viav pob nyiaj siv.

Cov modules lawv tus kheej yuav zaum sib pauv tawm. Tshuab txav nrawm nrawm, tus nqi poob qis dua. Tab sis lub tsev kho vaj tse uas koj tau khiav lawv los ntawm? Uas yog kim los hloov, yog li ua nws txoj cai thawj zaug.

 

Hauv qab kab

 

Tsim nyogSFP + transceiversTeeb tsis yog hais txog kev muaj kev kho vajtse ceev tshaj plaws. Nws yog hais txog txuam koj cov kev xav tau tiag tiag nrog thev naus laus zis thiab tsis dhau-}}}}} engineမ်ineering yam rau cov teeb meem koj tsis muaj. Feem ntau me me rau nruab nrab cov lag luam tsis xav tau 100g mus rau lub desktop. Lawv xav tau kev txhim khu kev qha, kom zoo -} Siv 10g qhov chaw nws teeb meem.

Pib nrog koj cov tub ntxhais ua haujlwm. Tau txais koj cov neeg rau zaub mov sib txuas txoj cai, nco ntsoov tias koj cov ntaub ntawv cia tsis tau ntim, thiab ua haujlwm sab nraud. Koj yuav xav tsis thoob li cas SEAP POV THAWJ cov kev hloov tuaj yeem coj koj tsis hloov txhua yam ib zaug.

Thiab rau txoj kev hlub ntawm txhua yam kev paub, sau cov ntaub ntawv koj nruab. Tus qauv naj npawb, cov sijhawm teeb tsa, chaw nres nkoj mus qhov twg. Yav tom ntej koj (lossis lwm tus neeg ntxiv) yuav ua tsaug rau koj thaum muaj qee yam xav tau kev daws teeb meem ntawm 3 teev sawv ntxov.
