IbMPO (Ntau -fiber Push On) adapterua haujlwm raws li kev sib txuas lus sib txuas ntawm ob MPO- txiav cov fiber ntau txuas, ua kom siab - qhov sib txuas ntawm qhov sib txuas ntawm qhov sib txuas hauv cov txheej txheem cabling. Hauv cov ntaub ntawv chaw ib puag ncig ua haujlwm ntawm 40G, 100G, thiab nce 400G Ethernet nrawm, cov khoom siv no muab lub cev sib dhos rau 8, 12, lossis 24-fiber ribbons thaum tswj kev poob qis feem ntau qis dua 0.35 dB ib khub mated. Lub adapter txoj haujlwm zoo li dag tau yooj yim - tuav ob lub ferrules hauv cov khoom siv kho kom raug zoo -tsis tau qhov tshwm sim ntawm kev xaiv tsis zoo los ntawm kev sib txuas pob nyiaj siv, cov phiaj xwm polarity, thiab kev ntseeg tau ntev hauv txoj hauv kev uas tsis pom tseeb kom txog thaum muaj qee yam tawg.
Qhov 12-Fiber yuam kev uas raug nqi peb Racks
Rov qab rau xyoo 2019, kuv tau teev tag nrho Base -12 cov txheej txheem rau kev xa tawm 400-rack. Ua zoo meej rau ntawm daim ntawv. Lub 40G QSFP + transceivers peb tau siv thaum lub sij hawm khiav parallel optics hla 12 fibers-plaub kis, plaub tau txais, plaub tsaus nti. huv. Elegant. Tus neeg muag khoom cabling nyiam nws vim tias 12-fiber trunk cables yog lawv lub khob cij thiab butter.
Kaum yim lub hlis tom qab, peb pib tsiv mus rau 100G. QSFP28 modules peb xaiv? Lawv tsuas siv 8 fibers xwb. Dheev txhua qhov txuas muaj plaub lub fibers uas tsis tau siv zaum ntawd, thuam peb. Kev hloov kho 400G peb tab tom npaj tam sim no siv 8 fibers ib yam nkaus. Peb tau txais 12-fiber infrastructure nqa 8-fiber tsheb thauj mus los, thiab hloov pauv hloov pauv txhua qhov chaw.
Kuv tsis tau hais tias Base-8 yog qhov tseeb tiag. Tab sis yog hais tias ib tug neeg tau zaum kuv hauv 2019 thiab hais tias "xav txog qhov twg transceiver technology mus, tsis yog qhov twg," Kuv yuav txuag tau kwv yees li $ 180,000 hauv cov ntawv hloov dua siab tshiab thiab mob taub hau tsis tu ncua ntawm kev tswj ob qhov sib txawv fiber ntau hauv tib lub chaw.
Qhov kev txiav txim siab adapter ntws los ntawm qhov no. Koj yuav tsum paub- paub tiag tiag- fiber ntau suav koj tau ua li cas ua ntej koj pib tsim cov vaj huam sib luag.
Polarity yuav rhuav koj lub lim tiam
Muaj qhov tshwj xeeb ntawm kev ntxhov siab tshwj xeeb rau kev daws teeb meem polarity yuam kev ntawm 2 AM thaum qhov txuas tseem ceeb yuav tsis tuaj. Lub cev txheej zoo li zoo. Optics qhia lub teeb. Hloov xwb... tsis pom kev sib txuas.
Peb txoj kev polarity muaj nyob, thiab kev lag luam tsis tuaj yeem pom zoo rau qhov twg yog qhov zoo tshaj:
Txoj Kev Asiv tus yuam sij - mus txog qhov tseem ceeb -down adapter nrog ncaj- los ntawm kab. Fiber 1 maps rau fiber 1 ntawm qhov kawg. Yooj yim hauv lub tswv yim, tab sis koj yuav tsum tig lub connector orientation ntawm ib kawg, uas txhais tau hais tias txawm lub adapter los yog cable ua ib yam dab tsi tsis yog - pom tseeb.
Txoj kev Btig cov haujlwm fiber ntau hauv lub cable nws tus kheej. Fiber 1 ntawm ib kawg txuas rau fiber 12 ntawm lwm qhov. Cov adapters yog qhov tseem ceeb - mus txog qhov tseem ceeb -up. Cov neeg ntxub qhov no vim qhov crossover tsis pom -koj tsis tuaj yeem qhia los ntawm kev saib Txoj Kev B cable tias nws hla.
Txoj kev Csiv khub- ntse flipping. Nyob ib sab ntawm fiber ntau sib pauv txoj haujlwm. Nws yog kev sim ntawm kev sib haum xeeb thiab sib cav tias qhov phem tshaj plaws ntawm ob lub ntiaj teb.
Nov yog qhov tshwm sim tiag tiag hauv thaj teb: ib tus neeg xaj Method A cables, lwm tus xaj Method B adapters vim tias lawv pheej yig dua lub lim tiam, tus neeg thib peb muab lawv ua ke, thiab tsis muaj dab tsi ua haujlwm. Kuv tau pom cov kws kho mob "kho" qhov no los ntawm kev sib pauv ib tus neeg fibers ntawm LC breakout modules kom txog rau thaum qhov kev sib txuas tuaj, tsim cov txheej txheem polarity uas tsis muaj nyob hauv ib qho qauv thiab yuav ua rau txhua tus neeg kov nws tom qab.
Kuv txoj hauv kev tam sim no: xaiv ib txoj hauv kev, sau nws obsessively, sau txhua yam, thiab tsis kam hloov. Kuv siv txoj kev A. Kuv tsis xav tias nws yog technically superior. Kuv xav tias qhov sib xws tseem ceeb tshaj qhov kev ua kom zoo.
Insertion Poob: Cov lus dag peb qhia peb tus kheej
Cov ntaub ntawv hais tias 0.35 dB qhov siab tshaj qhov nkag poob. Zoo heev. Koj tsim koj cov peev nyiaj txuas ib ncig ntawm qhov ntawd. Koj tau txais tej zaum 2 dB ntawm cov npoo rau 100-meter OM4 khiav ntawm 100G.
Dab tsi cov ntaub ntawv tsis hais txog:
Qhov 0.35 dB tau ntsuas nrog lub Hoobkas- cov khoom txuas tshiab, chav kuaj- qib tu, thiab thov Vajtswv rau txhua tus vajtswv saib xyuas photonics. Hauv qhov chaw cov ntaub ntawv tiag tiag nrog cov neeg cog lus uas tej zaum yuav lossis tsis tau ntxuav qhov kawg - ntsej muag, nrog cov plua plav thiab cov huab cua thiab qhov dav dav ntawm qhov chaw tsim khoom, koj tab tom saib ntawm 0.5 dB yog tias koj muaj hmoo. Kuv tau ntsuas 0.8 dB ntawm adapters uas tau "tsuas yog ntsia."
Tus neeg ua txhaum yog yuav luag ib txwm muaj kab mob. Ib qho 1-micron plua plav particle ntawm cov tub ntxhais fiber ntau uas yog 50 microns thoob plaws tsis zoo li ntau. Nws yog txaus los ntsuas qhov poob thiab muaj feem cuam tshuam rau lub ferrule nto thaum mated nyob rau hauv lub caij nplooj ntoos hlav siab.
Thaum kawg peb tau txiav txim xyuas qhov ntsuas ntawm txhua qhov xwm txheej. Tsis yog -negotiable. Yog tias thev naus laus zis tsis tuaj yeem qhia kuv qhov kawg huv si - duab ntsej muag, lub connector tsis tau ntsaws rau hauv. Qhov no txo peb cov teeb meem "tsis muaj teeb" los ntawm qee yam xws li 60%.
Hom Adapter Tsis muaj leej twg ceeb toom kuv txog
Qhov ncaj -los ntawm adapter yog pom tseeb. Ob qhov chaw nres nkoj, ib qho ntawm txhua sab, ua raws ferrules, ua tiav.
Tab sis tseem muaj:
Txo -flange adaptersrau siab - panels. Cov no txuag tej zaum 2 hli dav, uas suab tsis tseem ceeb kom txog rau thaum koj tab tom sim kom haum 72 chaw nres nkoj hauv 1U. Kev lag luam tawm -tawm yog lawv nyuaj rau rho tawm - thaj tsam tsawg dua los tuav- thiab kuv cov kws tshaj lij ntxub lawv.
Angled adaptersrau APC kev sib txuas hauv ib qho - hom kev xa tawm. Lub 8-degree lub kaum sab xis polish uas txo cov kev xav rov qab kuj txhais tau tias koj tsis tuaj yeem koom nrog APC txuas rau UPC adapter. Koj yuav ua puas rau ob leeg. Nug kuv seb kuv paub li cas.
Hybrid adaptersuas coj MPO ntawm ib sab thiab ib hom txuas sib txawv ntawm lwm qhov. Kuv tau pom MPO-rau-MTP (yog, lawv yog cov cuab yeej sib xws tab sis cov khoom lag luam tseem ceeb rau lub hom phiaj lav), MPO-rau-CS rau 400G daim ntawv thov, txawm tias oddball proprietary ua ke.
Tseem muaj covpoj niam txiv neej lo lus nugtsis muaj leej twg piav qhia meej txog thaum koj xaj yuam kev. MPO connectors tuaj nyob rau hauv txiv neej (nrog coj tus pins) thiab poj niam (nrog rau tus pin qhov). Lub adapter yuav tsum sib phim. Tus qauv "Hom A" adapter xav tau txiv neej ntawm ib sab, poj niam ntawm lwm tus. Hais kom tus poj niam-rau- poj niam adapter thiab tom qab ntawd sim ntsaws ob tus txiv neej-pinned connectors? Cov pins tsis muaj qhov twg mus. Kuv twb pom tib neeg sim yuam nws. Tsis txhob.
Lub Siab -Density Arms haiv neeg
1U thaj vaj huam sib luag siv los tuav 24 LC duplex ports. Ces 48. Ces 72. Ib tug thaum kawg tswj 144.
Rau MPO, qhov kev nce qib mus los ntawm 6 adapters ib 1U (24 fibers ntawm 4-fiber-per-adapter) mus rau 12 adapters (48 fibers) rau panels thov 24 lossis ntau dua MPO ports hauv 1U.
Qee lub sij hawm, qhov ceev yuav ua rau pathological. Kuv tau saib tech siv 40 feeb sim tshem tawm ib lub cable los ntawm 144-chaw nres nkoj LC vaj huam sib luag vim tias nws cov ntiv tes tsis tuaj yeem ncav cuag cov cables nyob ib puag ncig. Lub cable nws tau sim rho tawm yog thib peb los ntawm hauv qab hauv ib pawg tsib tob. Nws thiaj li tso tseg thiab rub peb lub cables uas nyob ib sab los tsim qhov chaw ua haujlwm.
Ultra-siab- MPO panels muaj qhov teeb meem zoo ib yam, phem dua. Lub cev txuas yog dav dua. Cov cables yog nruj dua -ribbon fiber ntau tsis khoov zoo li duplex. Thiab txhua tus ntawm cov connectors sawv cev rau 12 lossis 24 fibers uas yuav xav tau kev daws teeb meem kev nkag mus thaum kawg.
Kuv txoj cai ntawm tus ntiv tes xoo: spec rau txog 70% ntawm qhov siab tshaj plaws tshaj tawm. Tawm hauv chav mus ua haujlwm.
APC vs. UPC: Ib qho -Cov lus nug hom
Ntau- hom ntawv thov yuav luag thoob plaws ntiaj teb siv UPC (Ultra Physical Contact) polish. Lub tiaj tus ferrule endface ua haujlwm zoo thaum koj thawb 850nm lub teeb hla 100 meters.
Tib - hom yog txawv. Qhov ntev dua, cov peev nyiaj siv hluav taws xob ntau dua, thiab cov yam ntxwv wavelength ua rau rov qab - xav txog qhov kev txhawj xeeb tiag tiag. APC (Angled Physical Contact) polish xa cov teeb pom kev tawm ntawm lub kaum sab xis es tsis ncaj nraim rov qab rau hauv laser, uas tseem ceeb rau qee hom transceiver ntau dua li lwm tus.
Ntawm no yog qhov: ib qho - hom hauv chaw ua haujlwm cov ntaub ntawv tseem tsis tshua muaj. Feem ntau lub tsev kawm ntawv thiab intra- tsev khiav haujlwm yog OM4 multi- hom vim nws pheej yig dua, cov transceivers pheej yig dua, thiab 100-meter deb tsis xav tau ib hom kev muaj peev xwm.
Tab sis 400G tab tom hloov qhov no. 400G-FR4 thiab DR4 optics khiav ntawm ib qho - hom fiber ntau. Hyperscalers tau ua ib hom - rau xyoo; cov tuam txhab tam sim no ua raws. Yog tias koj tab tom tsim kev tsim kho tshiab thiab cia siab tias yuav mus dhau 100G, tsawg kawg xav txog seb ib qho - hom ua rau muaj kev nkag siab zoo li cas.
Rau cov adapters, qhov no txhais tau tias stocking UPC (feem ntau xiav vaj) thiab APC (tsev ntsuab). Tsis txhob sib tov. Kuv sau lub txee, sau lub vaj huam sib luag, thiab tseem pom UPC txuas txuas rau hauv APC adapters ib zaug lossis ob zaug hauv ib xyoos.
Dab tsi cov neeg muag khoom tsis tso rau ntawm nplooj ntawv Ib
Kev ntsuas lub neej muaj nyob, faus rau hauv cov ntawv zoo. MPO adapter tsim nyog yuav tsum tswj 500-1000 mating cycles ua ntej qhov kev sib tw precision degrades mus rau qhov cuam tshuam rau kev poob. Nyob rau hauv ib qho kev sib txuas uas tau rov ua dua tas li, qhov tseem ceeb. Hauv kev sib txuas ntawm lub cev ruaj khov uas tau kov ob zaug hauv kaum xyoo, nws tsis yog.
Kev khiav hauj lwm qhov kub thiab txias. Feem ntau cov adapters tau ntsuas -40℃rau +75℃. Tshwj tsis yog tias koj lub chaw khaws ntaub ntawv muaj qhov txias txias tsis ua haujlwm lossis koj tab tom xa mus rau qhov chaw txawv txawv, koj yuav tsis raug txwv cov kev txwv no. Kuv yeej tsis tau muaj ib lub adapter poob vim qhov kub thiab txias.
Flammability ntsuas. UL94-V0 yog tus qauv. Yog tias koj lub chaw muaj cov cai tshwj xeeb, xyuas qhov no. Kuv tsuas yog ntsib nws raws li qhov teeb meem ib zaug, nyob rau hauv ib qho chaw uas muaj kev tuav pov hwm txawv txawv.
Cov khoom tseem ceeb me ntsis. Zirconia ceramic tes tsho yog tus qauv rau kev sib tw precision. Qee qhov pheej yig adapters siv bronze alloy tes tsho. Cov bronze ua haujlwm zoo rau cov ntawv thov xws li hnav, tab sis hnav sai dua thiab tiv taus cov kab mob tsis zoo. Tus nqi sib txawv yog tsawg. Txais cov ceramic.
Qhov xwm txheej txee
Tam sim no, hauv peb qhov chaw tseem ceeb, kuv khaws MPO adapters hauv qab no hauv Tshuag:
12-fiber Hom A, qhov tseem ceeb-up/key-down, UPC, lub tes tsho ceramic (tus neeg ua haujlwm)
8-fiber Hom A rau Base-8 khiav (tsawg dua qhov kuv xav tau)
12-fiber APC rau thaj tsam ib leeg peb tau maj mam tsim tawm
Reduced-flange 12-fiber for two specific high-density panels that some previous architect specified
Cov neeg muag khoom kuv tau muaj kev paub zoo nrog: US Conec (tus thawj MTP tus tsim qauv- tus nqi zoo tshaj, tsis muaj kev sib cav txog qhov zoo), Senko (zoo sib npaug ntawm tus nqi thiab kev ua tau zoo), thiab ob peb daim ntawv cog lus cov tuam txhab hauv Shenzhen uas ua rau cov khoom lag luam tsim nyog yog tias koj qhia kom zoo thiab tshawb xyuas cov khoom xa tuaj.
Cov neeg muag khoom kuv tau muaj kev tsis zoo nrog: Kuv tsis tau sau qhov ntawd. Cia peb hais tias qhov kev xaiv pheej yig tshaj plaws ntawm Alibaba yog pheej yig vim li cas, thiab kuv muaj ib lub tub rau khoom uas muaj cov khoom siv nrog cov tes tsho tsis pom zoo uas tsis tau ua rau hauv kev tsim khoom.
Kev Xeem: Peb Ua Tau Li Cas
Txhua lub cev cable tau kawg -lub ntsej muag tshuaj xyuas ua ntej kev teeb tsa. Tsis yog -negotiable.
Peb sim ntsuas qhov poob ntawm kev khiav haujlwm tshiab siv lub teeb pom kev zoo thiab lub ntsuas hluav taws xob -tsis yog OTDR. OTDRs yog qhov zoo rau kev nrhiav qhov yuam kev ntawm kev khiav mus ntev tab sis tsis muaj kev daws teeb meem kom raug tus yam ntxwv ntawm 30-meter txheej cabling ntu nrog ntau lub ntsiab lus sib txuas. Cov xwm txheej tso tawm tseem ceeb tshaj li tib neeg paub, yog li peb siv mandrel-wrapped reference cables los tsim cov hauv paus.
Kev txheeb xyuas polarity tshwm sim los ntawm kev pom qhov pom. Tech ntawm ib kawg illuminates fiber 1 nrog ib tug VFL (pom qhov yuam kev locator), tech ntawm qhov kawg paub meej tias qhov chaw nres nkoj teeb. Nthuav, zoo, nyuaj rau mess.
Peb tsis kuaj txhua tus adapter ib tus zuj zus ua ntej kev teeb tsa. Peb tau sim txoj kev ntawd; tus nqi zog tshaj tus nqi adapter los ntawm ib qho ntawm tsib. Hloov chaw, peb siv cov khoom lag luam muaj npe nrov, tshuaj xyuas cov khoom xa tuaj, thiab hloov tsis ua haujlwm. Kev poob qis tau qis dua 0.5% tshaj rau xyoo.
Dab tsi ua rau kuv nyob hmo ntuj
400G thiab 800G transceivers tau thawb mus rau qhov sib txawv ntawm cov ntawv sib txawv. MPO-16 muaj nyob tab sis tsis tau ua tiav kev saws me nyuam loj. Cov CS thiab SN connectors muaj qhov ntom ntom dua rau kev siv tib hom kev sib txuas. Muaj qhov ua tau tiag tiag uas ib xyoo caum txij li tam sim no, MPO infrastructure txhua tus txhim kho niaj hnub no yuav yog cov cuab yeej cuab tam, kev txhawb nqa tab sis tsis zoo.
Kuv tsis muaj kev daws teeb meem rau qhov no. Tsis yog lwm tus ua. Qhov zoo tshaj plaws uas kuv tuaj yeem ua tau yog tsim rau kev txhim kho yooj yim dua - qhov chaw lub cev txaus nyob rau hauv txoj hauv kev, thaj vaj huam sib luag uas tuaj yeem hloov pauv yam tsis siv lub pob tw rov ua dua tshiab, cov ntawv hloov pauv tsis yog ncaj qha - cov vaj huam sib luag uas siv nyiaj tso cai.
Thiab ntxuav cov connectors. Ib txwm ntxuav cov connectors.
Qhov ntawd yog qhov kuv tau kawm txog MPO adapters tshaj li xya xyoo ntawm cov ntaub ntawv chaw ua haujlwm. Nws tsis yog lus. Kuv tsis tau kov ribbon splicing, los yog cov nuances ntawm khoov-insensitive fiber ntau ntawm nruj routing, los yog tag nrho cov mess ntawm sab nraum zoov OSP- ntsuas adapters rau tsev kawm ntawv interconnects. Muaj cov neeg paub cov ncauj lus zoo dua li kuv ua.
Qhov kuv paub yog tias lub adapter -qhov no $4 daim yas thiab ceramic uas tsis muaj leej twg xav txog txog thaum qee yam tawg - zaum hauv txoj kev tseem ceeb ntawm txhua qhov txuas fiber ntau hauv lub tsev. hwm nws raws li.
