10G SFP Transceivers yog tsim rau Datacent
Nov 21, 2025| 
Yog tias koj tau ua haujlwm hauv Datacenter lossis txawm tias tsuas yog nrhiav tau cov khoom siv network ntawm 2 teev sawv ntxov (peb txhua tus tau muaj), koj paub tias10G SFP transceivermodules yog qhov txhia chaw. Thiab kuv txhais tau tias txhua txhia qhov chaw. Lawv zoo li USB cables ntawm kev lag luam hauv ntiaj teb kev lag luam, tshwj tsis yog kim dua thiab koj yuav tsum paub tias koj yuav tau yuav dab tsi.
Sr variant tsis muaj leej twg tham txog txaus
Yog li ntawm no yog yam txog10gbase{{0- sr modules - Kuv siv 850nm vcitters. VCELS sawv ntsug rau ntsug {{4} kab noj hniav saum toj {}}}}}}}}}}}}}}}}}}} attense txoj kev mus tua lub teeb los ntawm multimode fiber ntau. Lub vev xaib 850nm wavelength nyob hauv qhov chaw qab zib uas muaj fiber ntau tsis ua kom puas koj lub teeb liab ntau dua.
Cov transceivers tuaj yeem thawb mus rau 300 metres ntawm 50/125 teev MMF (multimode fiber ntau, rau cov uas tsis poob dej hauv cov pob nrov tsis tau). Tam sim no, 300 metres yuav tsis zoo li ntau yog tias koj xav txog ntev- haul telecommunications, tab sis nyob rau hauv ib tug datorging? Uas yog cia li mus ib txhis. Feem ntau cov datacenter racks tsis txawm tias 50 meters sib nrug. Koj tuaj yeem tuaj yeem sib txuas tawm ntawm qhov xaus ntawm daim teb football thiab tseem muaj chaw cia.
Cov ntaub ntawv ua haujlwm ntaus nqi 10.3GPPS, txawm tias yog kev nkag mus tiag tiag koj yuav pom nyob ntawm ... Zoo, txhua yam. Koj cov fiber ntau, muaj pes tsawg lub cable tau khoov ntawm cov ceg tawv uas tsis quav ntsej, puas yog cov khoom siv lc constors kom zoo (spoiler: lawv yuav tsis thawj zaug).
Kub ntsaws vim tias tsis muaj leej twg muaj sijhawm
Ib qho tshwj xeeb uas tsis tau txais nuj nqi txaus - kub hloov tau. Koj tuaj yeem tsuas yog Yank cov khoom no tawm thiab sib pauv lawv thaum lub kaw lus khiav. Qhov no yog loj heev. Kuv tau pom lub network engineers cia hnia cov qauv no vim tias lawv tsis tas yuav teem sijhawm thaum 3 teev sawv ntxov txog hnub Sunday los hloov cov kev ua txhaum kev hloov pauv.
Lub duplex lc txuas interface yog cov khoom zoo nkauj. Ob tug fibers, ib qho rau xa thiab ib qho kom tau txais. Cov kev ua physics yooj yim, tiag- lub teeb mus ib txoj kev, lub teeb rov qab rau lwm txoj kev. Tab sis kev siv cov teeb meem ntau dua li koj xav. Qhov zoo tshaj ntawm cov txuas txuas no tuaj yeem ua lossis tsoo koj cov nyiaj txiag tag nrho.
Kub npaum li cas uas yog teeb meem
Kev Ua Haujlwm Cov Ntaub Ntawv Kub los ntawm 0 Qib rau 70 Qib yog cov qauv, thiab ua siab ncaj? Uas feem ntau txaus. Tshwj tsis yog koj txhim kho cov cuab yeej sib xyaw ua ke hauv kev taug kev- hauv chav txias lossis lub chaw ua haujlwm rau ACE (uas, tshwm sim ntau dua li cov thawj tswj hwm xav lees paub). Cov khoom siv hluav taws xob nkaus xwb 3.3V hluav taws xob ua kom yooj yim - Tsis muaj weird voltage uas yuav ua rau koj lub peev nyiaj txiag zoo li muaj kev puas tsuaj.
Ntawm no yog qhov twg nws tau txais nthuav - qhov ntau- prococol tshaj plaws
Qhov no yog dab tsi feem ntau cov ntawv qhia tau zoo nkauj tab sis nws yog qhov ua tau zoo nkauj txias. Cov 10g SFP Transceiver modules tsis yog cia li ua 10GBase - sr ntawm 10.31Gbps. Lawv yuav ua 10GBase {{- sw ntawm 9.95gbps, uas yog qhov zoo ib yam tab sis rau sonet / sdh tes hauj lwm. Tom qab ntawd koj tau txais tag nrho cov channel fiber channel nce nyob rau ntawd.
8x fc ntawm 8.5GBPs . 4 x fc ntawm 4.25gbps {}}} x fc ntawm 2.125gbps. Txawm tias 1x FC ntawm 1.0625Gbps. Thiab, me ntsis randomly, 1000base - sr Ethernet tau pov rau hauv kev sib xyaw ib yam nkaus. Nws zoo li tus transceiver yog hais tias "Yeah, Kuv tuaj yeem ua qhov ntawd thiab, vim li cas tsis?"
Qhov no rov qab sib xyaw ua ke yog qhov muaj txiaj ntsig ntau dua li cov neeg paub. Koj tau txais qee qhov kev cia ntawm legacacacacacacacy uas tseem siv 4g fiber channel? Txias, tib transceiver ua haujlwm. Xav tau los muab 10 G Ethernet txuas? Tib lub module. Nws tsis heev universal, tab sis nws ze txaus uas koj tuaj yeem ua qauv rau koj cov khoom lag luam spars tsis muaj kev tswj hwm tus skus sib txawv.
Qhov tho txawv tab sis tseem ceeb ua raws cov khoom
MSA SFP + SPECICATION SFF {5 5}} 8431 ua raws. IEEE 802.3ae 10GBase-SR / SW ua tsis tiav. Txhua tus qauv FC los ntawm 1G txog li 10G. Qhov no tsis yog txaus siab nyeem, tab sis nws txhais tau tias tus qauv yuav ua tau haujlwm tiag tiag nrog cov khoom siv los ntawm cov khoom muag sib txawv, uas yog ... tsis yog ib txwm muab hauv kev sib txuas. Kuv tau pom cov qauv uas ua tau raws li cov specs tab sis tseem tsis kam txuas nrog qee yam hloov pauv vim qee qhov txawv txav ntawm kev siv.
Peb lub {-} lub xyoo tsim kev tiv thaiv yog qhov zoo. Tsis amazing, tab sis decent. Feem ntau ntawm cov khoom no yog swb thawj zaug lossis lub xeem kawg, yog li lub sijhawm lav yog yuav luag kawm.
Dab tsi lawv tsis qhia koj hauv cov khoom lag luam
Kev txwv qhov deb yog qhov tiag thiab lawv tsis yog theoretical. Tias 300 {{{5 5}} meter 1.0 fiber, kom muaj zog, huv si. Lub ntiaj teb kev xa tawm tiag? Koj yuav xav taw rau 250 meters max yog tias koj xav pw tsaug zog zoo thaum hmo ntuj. Fiber tsis yog kev zam txim li tooj liab thaum nws los txog "eh, ze txaus" kev teeb tsa.
Lub vev xaib 850nm nthwv cua kuj txhais tau tias koj txwv rau ntau cov fiber ntau. Tsis muaj singlemode nrog SR Transceivers-} Yog qhov sib txawv sib txawv (LR lossis er lossis er nnmm lossis 1550nm). Multimode yog pheej yig dua thiab fiber nws tus kheej yog qhov yooj yim dua ua haujlwm nrog, tab sis nws tau txais qhov kev ncua deb hauv. Physics tsis sib tham.
Kev noj fais fab tsis muaj npe nyob rau hauv daim ntawv ntawd cov ntawv ntawd tab sis nws feem ntau nyob ib puag ncig 1 watt, tej zaum tsawg dua. Tsis tau zoo li ntau kom txog thaum koj muab nws tso rau ntawm 48 lossis 96 chaw nres nkoj hauv lub hloov thiab mam li ploj zuj zus. Qhov no yog vim li cas datacenter hloov lub suab zoo li dav hlau engins - Lawv tsis yog li txias cov asics.
Ua tau cov khoom no
Lub TTL Logic interface tsuas txhais tau hais tias tus module tham nrog tus tswv tsev system siv cov qib kev cav txheem. Tsis muaj dab tsi tshwj xeeb muaj, tab sis nws tsim nyog teev vim tias qee cov qauv kev hloov pauv me me siv cov phiajcim sib txawv uas tuaj yeem ua rau sib txawv mob taub hau.
Thawb nws mus rau SFP + tawb kom txog thaum nws nyem. Txuas koj cov fiber rau lub LC connectors. Xiav yog feem ntau tau kis, tab sis kev ncaj ncees, koj tau pom cov neeg muag khoom sib txawv vim tias lawv tau hloov pauv TX thiab RX. Tus qauv yuav tsum tau tso tseg cia thiab yog tias koj muaj hmoo, koj link teeb los txog thiab koj tau 10 gigs ntawm kev sib sau npaj mus.
Yog tias nws tsis ua haujlwm tam sim ntawd (uas tshwm sim), koj pib cov txheej txheem kev lom zem ntawm kev daws teeb meem. Yog fiber ntau huv? Koj puas tau tshem cov hmoov av kaus mom? Puas yog tus module tau zaum zoo? Puas yog qhov chaw nres nkoj tau teeb tsa yog qhov hloov kho? Puas muaj ib tus neeg teeb tsa qhov tsis ncaj ncees lawm nrawm / duplex nqis? Puas yog cov Fiber ntau thaj Cable ua qhov tseeb tiag tiag Om3 / Om4 thiab tsis yog qee leej Om1 uas qee tus neeg mislabeled?
Kev lag luam tsis muaj leej twg tham
Ntawm no yog ib yam dab tsi nthuav - Cov qauv no siv tau tus nqi li $ 500 {400} 800 txhua xyoo caum dhau los. Tam sim no koj tuaj yeem nrhiav lawv rau $ 30-50 los ntawm cov neeg muag khoom thib peb, tej zaum $ 150-200 los ntawm OEM. Tus nqi luv yog thoob plaws qhov chaw thiab qhov ncaj ncees, ntau ntawm nws yog hom. Qhov tseeb transceiver sab hauv yog tej zaum tau ua los ntawm tej zaum nyob rau hauv lub ntiaj teb, tom qab ntawd cov tuam txhab sib txawv ua rau nws thiab them ib yam dab tsi uas lawv xav tias lawv tuaj yeem tau ploj mus.
Dev ib sab yuav no txhua yam. Zoo li, pallet ntau. Thaum koj tsim tawm ib lub plhaub taum tshiab nrog 2000 chaw nres nkoj ntawm 10g sib txuas, tus nqi transceiver ntxiv rau ntawm $ 50 tus nqi. Qhov ntawd yog $ 100K tsuas yog hauv kev hloov pauv ua ntej koj txawm xav txog qhov hloov pauv, cables, lossis kev ua haujlwm nruab siab.
Vim li cas cov datacacing tshwj xeeb?
Cov npe hais txog Datacacent thiab muaj qhov laj thawj rau qhov ntawd. Cov 10 G SFP Transceiver modules yog lub hom phiaj tseem ceeb - ua rau datosserer kev ncua thiab datacenter kev lag luam thiab datacenter. Koj xav tau 10G ceev, koj tau txais luv (nyob rau hauv 300m yeej ib txwm), koj xav tau cov khoom siv kub ua haujlwm rau kev ua haujlwm nrog ntau tiam kev sib txawv ntawm cov cuab yeej.
Tsev kawm ntawv cov tes hauj lwm siv lawv ib yam nkaus, paub tseeb. Cov tuam tsev lag luam. Qee cov ntawv thov tshwj xeeb. Tab sis cov ntim nyob hauv cov chaw nkaum. Cov phooj ywg zoo li AWS, Google, Microsoft {4 4}} Lawv siv ntau lab ntawm cov no. Txhua tus neeg rau zaub mov txuas rau saum - ntawm {{rack hloov, txhua txoj hlua khi ntawm kev sib cav sib ceg, sib txawv ntawm cov cheeb tsam sib txawv.
Qhov kev nyiam fiber ntau hauv Datacent yog tus nqi ib nrab (MMF yog qhov pheej yig dua SMF) thiab ib nrab} ntawm Dataremode Expended Expended, yog li vim li cas them nyiaj ntxiv rau nws? Qhov 850nm wavelength yog paub tab Technology, cov vcels lasers yog kev ntseeg tau thiab pheej yig rau chaw ntawm nplai. Nws txhua tus ntxiv rau qhov chaw qab zib rau daim ntawv thov tshwj xeeb no.
Random cov ntsiab lus uas muaj teeb meem qee zaus
Lub duplex LC txuas daim ntawv tsis yog kev ua si ntxiv rau MBO / MTP cov ntawv thov ntau dua hauv 40G} Tab sis rau 10G, LC tseem yog hom. Daim ntawv me me, muaj zog heev, thiab muaj kaum tawm ntawm kev teeb tsa kev teeb tsa hauv lub teb.
Cov qauv kev ua raws cai tau hais ua ntej tsis yog khij cov khoom. Thaum koj tau cuam tshuam nrog multi - vendor ib puag ncig (uas yog yeej txhua qhov chaw), cov qauv kev ua raws li qhov twg los tiv thaiv tag nrho cov kev puas tsuaj. MSA (multi -} Cov lus pom zoo) tshwj xeeb muaj los xyuas kom paub tseeb kev hloov chaw ua haujlwm los ntawm cov sib txawv ua ke.
Kev soj ntsuam kub yog tsim mus rau hauv cov qauv ntawm cov kev kuaj mob digital (ddi), txawm tias nws tsis tau hais meej meej hu ua cov ntsiab lus yooj yim. Koj tuaj yeem nug cov qauv thiab tau txais tiag- sov nyeem, xa cov hluav taws xob, muab hluav taws xob, kev tsis ncaj ncees tam sim no. Qhov no yog pab tau zoo heev rau kev twv xyuas kev twv xyuas {}} Yog tias tus qauv pib khiav kub lossis lub zog kho qhov muag tau pib ua ntej nws ua tsis tiav.
Cov tshooj uas muaj kev muaj tiag intrudes
Tsis muaj dab tsi zoo tag nrho. Cov qauv no tsis ua tiav. Qee zaum lawv tsuas yog tso tseg ua haujlwm. Qee lub sij hawm lawv tau txais txawv qhov lawv yuav txuas mus rau tab sis koj tau txais pob ntawv Randet. Qee lub sij hawm lub zog kho qhov muag qis dua rau hauv qab no thiab koj qhov txuas tau ua rau muaj teeb meem tsis zoo vim tias muaj kev npau suav phem rau kev daws teeb meem.
Hmoov av tua cov transceivers. Mob siab, khaws cov hmoov av kaus mom thaum lub sij hawm tsis tau nruab. Ib qho speck ntawm hmoov av ntawm cov fiber ntau lub ntsej muag tuaj yeem tshawb xyuas lub teeb pom kev los tua koj cov nyiaj siv. Kev siv hluav taws xob sib txuas yog nws daim duab kos duab thiab txhua tus muaj lawv txoj kev nyiam (cov ntaub so dej caw, cov tshuaj ntxuav ultrasonic, txhua yam).
Lub 300-metre exchar spectrade yog tias koj siv OM1 lossis OM2 fiber hloov ntawm Om3 / OM4. Tab sis hav, tsawg kawg nws yog hom kev ua haujlwm, tsis zoo li sim mus thawb singlemode cia li tsuas yog tsis ua haujlwm tshaj li qee zaum ob peb metres.
Yog li ntawd, 10g SFP transce rau Datacacent. Lawv tsis yog muaj kev zoo nkauj, tsis muaj leej twg sau ntawv xav txog tej daim hais txog lawv, tab sis lawv yog qhov tseem ceeb kiag li infrastructure. Txhua daim vis dis aus, txhua API hu rau hauv lub datacent niaj hnub yuav muaj tsawg kawg ntawm cov qauv me me no. Lawv tsuas yog zaum muaj, blinking lawv cov xwm txheej coj, txav cov khoom ntawm 10 gigabits ib ob, ntsiag to ua Is Taws Nem ua haujlwm.
Thiab thaum lawv swb? Zoo, yog thaum txhua tus dheev nco lawv muaj nyob.
