Peb tau nug cov lus nug no ntau heev:"Peb puas yuav lo nrog LC connectors lossis hloov mus rau MTP / MPO rau peb cov ntaub ntawv nthuav dav?"Thiab ncaj ncees, cov lus teb yuav luag tsis yog ib qho yooj yim - lossis - - lwm txoj kev xaiv.

Nov yog qhov - feem ntau ntawm qhov tsis meej pem yog los ntawm cov ntaub ntawv tsis tiav. Tej zaum koj yuav nyeem tau tias MTP/MPO muab "12x qhov ceev" thiab xav tias, zoo heev, cia peb mus tag nrho - ntawm qhov ntawd. Tab sis tom qab ntawd koj paub tias koj cov keyboards uas twb muaj lawm siv LC interfaces, koj cov kws tshaj lij tau kawm ntawm LC txiav tawm, thiab mam li nco dheev koj tab tom saib kev teeb tsa hybrid uas tsis muaj leej twg ceeb toom koj txog.

Los yog tej zaum koj tau ua lej ntawm cov nqi tivthaiv thiab LC cables saib pheej yig dua ib fiber ntau. Muaj tseeb. Tab sis koj puas ua tau rau 6 teev ntawm kev teeb tsa ua haujlwm rau txhua 48 LC kev sib txuas piv rau 20 feeb rau qhov sib npaug ntawm MTP lub cev? Qhov ntawd yog qhov uas tus nqi tiag tiag duab tau nthuav.

Phau ntawv qhia no taug kev los ntawm cov ntsiab lus txiav txim siab tiag tiag-tsis yog qhov theoretical "no yog dab tsi txhua tus txuas yog" yam uas koj tuaj yeem pom hauv Wikipedia. Peb tab tom xav tias koj twb paub cov hauv paus. Yam koj xav tau yog clarity rauthaum txhua lub tshuab ua rau muaj kev nkag siab txog nyiaj txiag, qhov twg cov nqi zais tau tshwm sim, thiab yuav ua li cas kom tsis txhob ua yuam kev peb tau pom lwm pab pawg ua.

Tus nqi sib npaug tsis muaj leej twg hais txog

Cia peb pib nrog cov lej, vim qhov no yog qhov uas feem ntau cov kev npaj sib tham tau daig lossis mus rau sab.

Tus nqi ntawm cov khoom siv qhia ib zaj dab neeg tsis tseeb. Yog lawm, ib qho ua ntej - txiav tawm 12-fiber MTP lub cev cable raug nqi ntau dua rau LC duplex LC thaj qaum uas suav nrog tib lub fiber ntau. Qee zaum 2-3x ntxiv. Yog tias koj nres qhov ntawd, LC zoo li tus yeej pom tseeb.

Tab sis cov nqi tivthaiv yog feem ntau tsuas yog 15-25% ntawm tag nrho cov nqi cable. Tus so? Kev ua haujlwm, qhov chaw khib nyiab, kev tswj hwm cable, thiab kev saib xyuas tsis tu ncua. Qhov ntawd yog qhov kev sib piv flips.

Ib sab -los ntawm- sab rau 1,000-fiber kev xa tawm:(Cov nuj nqis no yog raws li cov nqi lag luam hauv Teb Chaws Asmeskas thiab lub sijhawm teeb tsa peb tau taug qab hla ntau qhov haujlwm. Koj cov lej yuav txawv, tab sis qhov sib piv yuav tuav.)

Cov ntaub ntawv cov ntaub ntawv: Cov nqi ua haujlwm raws li BICSI installer soj ntsuam 2023-2024; khib qhov chaw nqi los ntawm Uptime Institute colocation benchmarks; tus nqi ntawm cov khoom sib xyaw ua ke los ntawm tus neeg muag khoom quotes.

Lub takeaway tsis yog "MTP/MPO ib txwm yeej." Nws yog qhov ntawdcrossover point tshwm sim nyob ib ncig ntawm 400-500 fibers. Hauv qab no, LC tus nqi qis dua tuaj yeem cuam tshuam qhov sib txawv ntawm kev ua haujlwm. Saum toj no, MTP / MPO's installation efficiency thiab ceev zoo sib xyaw ua ke sai.

Peb muab:Peb tau pom cov pab pawg tau kub hnyiab los ntawm kev tsom mus rau qhov nqaim dhau ntawm cov lus qhia thawj zaug. Ib tus neeg siv khoom txuag $ 15,000 ntawm cov khoom los ntawm kev mus tag nrho -LC, tom qab ntawd siv $ 40,000 ntxiv rau kev teeb tsa thiab khiav tawm ntawm qhov chaw khib rau rau lub hlis tom qab. Qhov kev xaiv "khoom pheej yig dua" raug nqi rau lawv lub txee ntxiv thiab ib lub lis piam ntawm kev rov ua haujlwm kub ntxhov. Npaj rau qhov chaw koj yuav nyob hauv 3 xyoos, tsis yog koj nyob qhov twg niaj hnub no.

Qhov "High Density" tiag tiag zoo li

Cov lej zoo li "12x kev txhim kho kom zoo" tau cuam tshuam ntau heev. Nov yog qhov uas txhais tau tias hauv kev xyaum.

Siv tus qauv 1U thaj vaj huam sib luag. Nrog LC duplex adapters, koj tuaj yeem haum 48 chaw nres nkoj, uas muab rau koj 96 fiber ntau txuas. Zoo nkauj heev los ntawm cov qauv kev cai. Tam sim no sib pauv cov LC adapters rau MTP-24 interfaces. Tib qhov chaw 1U, tab sis tam sim no txhua qhov chaw nres nkoj tuav 24 fibers es tsis txhob 2. Qhov ntawd yog 1,152 fiber ntau sib txuas hauv tib lub khib nyiab.

Daim duab 1: Tib 1U khib qhov chaw xa tawm ntau qhov sib txawv fiber ntau. MTP-24 teeb tsa ua tiav 12 × qhov sib txuas ceev ntawm LC duplex.

Qhov no tseem ceeb tshaj plaws nyob rau hauv ib puag ncig uas qhov chaw khib nyiab yog txwv lossis kim. Colocation chaw them $800-1,500 rau ib lub khib nyiab txhua hli ua kom ceev tus nqi ncaj qha. Cov chaw lag luam cov ntaub ntawv nrog cov hneev taw ruaj khov ntsib tib lub siab los ntawm lub kaum sab xis sib txawv-txhua chav tsev khib nyiab uas siv los ntawm cabling yog ib qho uas koj siv tsis tau rau kev suav.

Tab sis kev ceev coj nws tus kheej cov nyom. Thaum qhov kev sib txuas MTP-24 tsis ua haujlwm, 24 fibers poob mus ib txhij tsis yog 2. Kev daws teeb meem yuav tsum muaj cov cuab yeej sib txawv thiab kev txawj ntse. Kev tu lub ntsej muag 24-fiber kawg yog kev koom tes ntau dua li kev ntxuav ib qho LC ferrule. Cov no tsis yog laj thawj kom zamsiab -qhov ceev fiber ntau cable-lawv yog laj thawj los npaj rau nws kom raug.

Vim li cas Feem ntau Cov Chaw Cov Ntaub Ntawv xaus siv ob qho tib si

Nov yog qee yam khoom lag luam tsis hais txog: feem ntau ntawm cov chaw zov me nyuam niaj hnub tsis xaiv ntawm LC thiab MTP / MPO. Lawv siv cov txheej txheem cabling architecture uas ua rau txhua lub thev naus laus zis uas nws nkag siab.

Daim duab 2: Peb- txheej txheej hybrid architecture - MTP/MPO ceev rau qaum, cassettes rau kev hloov, LC nkag tau rau patching.

Lub pob txha txheejsiv MTP/MPO trunk cables-feem ntau yog 12, 24, los yog 144-fiber assemblies- khiav ntawm lub ntsiab faib thav duab thiab sab saum toj- ntawm- qhov chaw khib. Ib qho 144-fiber MTP pob tw hloov qhov uas yuav txwv tsis pub 72 tus neeg ob lub cables. Txoj kev txuag hluav taws xob ib leeg yog qhov tseem ceeb, thiab kev teeb tsa ua ib qho teeb meem ntawm kev sib txuas ua ntej txiav tawm cov rooj sib txoos es tsis rub thiab txiav tawm kaum ob tus neeg cables.

Hloov txheej txheejyog qhov MTP ntsib LC. Cassette modules-cov ntaub ntawv me me nrog MTP cov chaw nres nkoj nyob tom qab thiab LC chaw nres nkoj nyob rau pem hauv ntej- zaum hauv fiber ntau thaj vaj huam sib luag. MTP lub cev ntsaws rau hauv qab; cov kws tshaj lij ua haujlwm nrog cov qauv LC sib txuas rau pem hauv ntej. Qhov no yog tus choj uas ua rau hybrid mus kom ze.

Patch txheejyog tag nrho LC. Server NICs, cia HBAs, thiab feem ntau hloov chaw nres nkoj siv LC-interfaced transceivers. Cov neeg ua haujlwm hnub-rau-hnub txav, ntxiv, thiab hloov pauv ua haujlwm nrog LC thaj qaum uas paub. Lawv tsis tas yuav paub lossis saib xyuas tias lub nraub qaum tom qab lub cassette yog MTP/MPO-lawv tsuas pom LC cov chaw nres nkoj.

Peb muab:Lub cassette yog unsung hero ntawm niaj hnub fiber infrastructure. Nws tso cai rau koj ntes MTP / MPO qhov ntom ntom thiab cov txiaj ntsig kev teeb tsa rau lub sijhawm ntev thaum khaws cia LC txoj kev nkag tau rau cov kev sib txuas uas hloov nquag. Yog tias koj tab tom tsim cov txheej txheem tshiab, pib koj txoj kev npaj los ntawm cov kab ntawv sab nraud - koj xav tau fiber ntau npaum li cas ntawm txhua qhov khib nyiab? Uas tsav koj lub cev specifications thiab koj LC chaw nres nkoj yuav tsum.

Polarity: Qhov yuam kev uas raug nqi hnub so

Yog tias muaj ib lub ntsiab lus uas peb tau pom cov teeb meem uas tsis tuaj yeem zam tau tshaj plaws, nws yog kev tswj hwm polarity hauv MTP / MPO systems.

Nrog LC kev sib txuas, polarity yog ncaj nraim -koj phim Tx rau Rx. Ntxoov nws, thiab koj pauv ob lub fibers. Siv 30 vib nas this. Nrog 12 lossis 24 fibers hauv ib qho kev sib txuas, kev ua lej tau nyuaj. TIA-568 tus qauv txhais tau peb txoj hauv kev, thiab kev sib xyaw ua ke tsis yog ua rau ib qho kev sib txuas ua tsis tiav-nws tuaj yeem sib tsoo ntau lub fiber ntau hauv txoj hauv kev uas mob siab rau kev kuaj mob.

Daim duab 4: MTP/MPO polarity method - position 1 mapping txiav Tx/Rx alignment. Hom B (rov qab) feem ntau yog rau cov khoom sib txuas.

Kev kho tsis nyuaj - nws tsuas yog xav taunpaj ua ntej xaj. Sau koj cov txheej txheem polarity. Xyuas kom koj cov cassettes, pob tw, thiab cov hlua khi tag nrho ua raws li tib txoj kev. Sau txhua yam. Thiab sim nrog MPO- muaj peev xwm tester ua ntej yuav nyob, tsis yog tom qab ib tus neeg tshaj tawm qhov txuas tsis ua haujlwm.

TIA-568.3-D qhia meej tias cov kev xeem coj yuav tsum txheeb xyuas ntawm 0.3 dB lossis poob zoo dua. Yog tias koj pom cov lej siab dua lossis cov txiaj ntsig tsis sib xws thoob plaws cov haujlwm fiber ntau, polarity yog thawj qhov uas yuav tsum tau kuaj xyuas. ^[1]

Yav tom ntej- Pov thawj: Dab tsi 400G thiab 800G txhais tau li cas rau koj cov cabling

Yog tias koj tab tom tsim cov vaj tse niaj hnub no uas xav tau 5-7 xyoo, 400G thiab 800G txoj kev teeb tsa tseem ceeb.

Nov yog txoj hauv kev: 100G parallel optics (SR4) siv 8 fibers nrog MTP-12 connectors. 400G DR4 siv tib 8-fiber mus kom ze. Tab sis 400G SR8 thiab 800G xa tawm mus rau 16-fiber MTP txuas rau ntau txoj kab ntau dua.

Daim duab 3: Network ceev evolution thiab coj connector xav tau. MTP-12 infrastructure txhawb kev hloov kho dua tshiab los ntawm 400G DR4; MTP-16 enables 400G SR8 thiab 800G.

Qhov cuam tshuam zoo: MTP / MPO lub cev pob zeb koj nruab hnub no rau 100G tuaj yeem ua haujlwm 400G DR4 nrog kev hloov pauv hloov pauv nkaus xwb- tsis tas yuav rov ua dua. Qhov ntawd yog qhov txiaj ntsig tseem ceeb tshaj LC-tsuas yog architectures, uas yuav xav tau ntxiv cov suav fiber ntau los txhawb qhov sib npaug ntawm qhov sib txuas ntawm qhov nrawm no.

Rau AI thiab ML pawg, qhov no twb muaj feem cuam tshuam. GPU-rau-GPU interconnects yog tsav 400G saws tam sim no, nrog 800G nyob ze qab ntug. Yog tias koj daim ntawv qhia kev muaj xws li kev suav loj,siab -qhov ceev fiber ntau cablenrog MTP/MPO tsis yog xaiv tau- nws yog lub rooj sib tw.

Kev Xeem: Tsis txhob hla ntu no

Kev kuaj MTP/MPO txuas tsis zoo ib yam li kev sim LC txuas, thiab qhov sib txawv tsis yog kev kawm xwb.

Kojua taukuaj MTP txuas nrog breakout cables thiab tus qauv duplex tester. Txuas qhov kev tawm mus rau MTP kawg, sim txhua tus khub fiber ntau ib leeg nrog koj OLTS, rov ua dua rau txhua txoj haujlwm. Rau 12-fiber connector, uas yog 6 lub voj voog ib kawg. Sib faib los ntawm txhua qhov kev sib txuas hauv koj qhov kev teeb tsa, ntxiv lub sijhawm teeb tsa rau kev siv cables, thiab koj tab tom saib cov txheej txheem kev sim uas yuav siv sijhawm 5-10x ntev dua li nws xav tau.

Niaj hnub no MPO- cov neeg ntsuas tshwj xeeb (xws li Fluke MultiFiber Pro) scan txhua txoj haujlwm fiber ntau ib txhij. IEC TR 61282-15 daim ntawv qhia kev xeem tam sim no pom zoo rau cov neeg sim nrog MPO interfaces raws nraim vim li no-lub sij hawm txuag tau zoo heev, thiab koj tshem tawm cov kauj ruam yuam kev ntawm kev tswj ntau qhov kev sib txuas. ^[2]

Kuaj txhua yam tom qab kev teeb tsa, ua ntej koj muab cov kev sib txuas rau hauv ntau lawm. Kev kis kab mob thiab polarity yuam kev yooj yim dua los kho thaum lub racks tsis nyob thiab pab pawg ua haujlwm tsis ua pa hauv koj lub caj dab.

Tau txais cov Cheebtsam txoj cai

Tsis yog txhua tus MTP / MPO connectors raug tsim sib npaug. Tus qauv MPO connector (ib IEC 61754-7) tau nyob ib puag ncig txij li xyoo 1990. MTP-US Conec's trademarked version-ntxiv ntau yam kev txhim kho uas tseem ceeb rau niaj hnubsiab -qhov ceev fiber ntau cable:

Floating ferrule tsimtxhim kho kev sib cuag ntawm lub cev, tshwj xeeb tshaj yog tseem ceeb thaum koj ntxiv fiber ntau

Hlau pin clamps(vs. yas ntawm generic MPO) txo tus pin breakage thaum rov mating cycles

Tighter manufacturing tolerancesxa cov kev poob qis dua thiab zoo sib xws -cov specs raug yog 0.15-0.35 dB rau qhov poob qis MTP vs. 0.25-0.50 dB rau tus qauv MPO

MTP thiab MPO yog lub cev sib xws -koj tuaj yeem ua khub MTP txuas rau MPO generic yam tsis muaj teeb meem. Tab sis rau cov txheej txheem tseem ceeb, qhov kev ua tau zoo sib txawv ua rau tus nqi them.

Thaum muab khoomfiber ntau optic connectorsthiab cov rooj sib txoos, nrhiav cov chaw muag khoom uas muab cov ntaub ntawv ntsuam xyuas tus kheej rau txhua lub cable. Generic "ua tau raws li spec" thov tsis tshua muaj txiaj ntsig tshaj qhov ntsuas qhov tseeb. Koj xav pom cov ntaub ntawv poob uas qhia tias cov fibers tshwj xeeb ntaus tus lej twg - yog li koj ntes teeb meem ua ntej lawv mus txog koj qhov chaw teeb tsa.

Installation xyaum uas tiv thaiv callbacks

Ob peb cov ntsiab lus installation tseem ceeb tsis sib xws:

Kev huv huv yog txhua yam.A 1-micron plua plav particle ntawm ib leeg-fiber LC ferrule cuam tshuam rau ib qho kev sib txuas. Tib yam ntawm MTP-24 ferrule tuaj yeem degrade ntau fiber ntau cores ib txhij. Ib txwm tshuaj xyuas lub ntsej muag kawg nrog lub ntsej muag fiber ntau (200x qhov kev nthuav dav tsawg kawg nkaus) thiab ntxuav nrog cov cuab yeej tsim nyog ua ntej txhua tus mating. Ob peb feeb ntxiv rau ib qho kev sib txuas txuag cov sij hawm ntawm kev daws teeb meem tom qab.

hwm bend radius.Txoj cai 10x- sab nraud- txoj kab uas hla yog siv rau ob qho tib si LC thiab MTP / MPO cables. Tighter khoov ua rau nce qhov poob thiab tuaj yeem ua rau microfractures uas tshwm sim raws li kev ua tsis tiav lub hlis tom qab kev teeb tsa. Siv cov kev tswj cov kab hluav taws xob tsim nyog- cov thawj tswj hwm ntsug, kab rov tav cov lus qhia- uas tuav lub vojvoog thoob plaws hauv txoj kev.

Sib phim poj niam txiv neej kom raug.MTP / MPO connectors tuaj nyob rau hauv txiv neej (nrog cov lus qhia pins) thiab poj niam (nrog pinholes) configuration. Cov khoom siv chaw nres nkoj yeej ib txwm yog txiv neej, yog li cov cables txuas rau cov khoom siv xav tau poj niam kawg. Lub cev-rau- kev sib txuas ntawm lub cev feem ntau siv txiv neej- mus rau- txiv neej nrog poj niam- mus rau - poj niam adapter. Kev quab yuam poj niam txiv neej tsis sib haum ua rau kev puas tsuaj rau phau ntawv qhia tus pins-thiab hloov cov khoom sib txuas uas puas ntawm lub rooj sib txoos ua ntej- txiav tawm yog kim.

Kaw txhua yam.Cov kaus mom plua plav muaj nyob rau qhov laj thawj. Txhua connector tsis nquag siv yuav tsum tau capped. Nws yog ib tus cwj pwm yooj yim uas tiv thaiv qhov feem ntau ntawm cov teeb meem kev sib txuas.

Yog li Koj Yuav Ua Li Cas Tiag?

Tsis yog muab qhov "nws nyob ntawm" cov lus xaus, ntawm no yog lub hauv paus kev txiav txim siab ua tau raws li cov kev txwv uas tau tsav qhov kev xaiv.

Daim duab 5: Kev txiav txim siab lub moj khaum - phim koj qhov project parameters mus rau txoj cai cabling.

Lub flowchart captures lub ntsiab lus txiav txim, tab sis ntawm no yog lub logic qab nws: kev sib txuas suav teev cov hauv paus ntsiab lus (TCO crossover tshwm sim nyob ib ncig ntawm 400-500 fibers), ceev yuav tsum tau override lub hauv paus (40G + parallel optics xav tau MTP / MPO tsis hais txog qhov teev), thiab hom phiaj xwm cuam tshuam rau kev siv lub tswv yim (tshiab tsim tuaj yeem ua kom zoo dua los ntawm kev kos;

Cov lus teb yog nyob ntawm koj tus lej tshwj xeeb- suav nrog kev sib txuas, kev xav tau ceev, khib qhov chaw txwv, nqi zog. Khiav koj tus kheej TCO tsom xam nrog cov nqe lus tiag. Rau kev taw qhia ntawm cov khoom specifications thiab kev cai sib dhos,hu rau EVOLUX tus kws tshaj lij pab neegpab kom phim cov khoom lag luam rau koj qhov kev xa tawm tshwj xeeb.

Kev xav zaum kawg:Cable infrastructure feem ntau muaj 10-15 xyoo lifespan. Cov kev txiav txim siab thev naus laus zis uas koj ua niaj hnub no yuav txhawb nqa cov khoom siv uas tseem tsis tau muaj. Tsim kom muaj peev xwm ntau dua li qhov koj xav tias koj xav tau-tus nqi ntxiv ntawm cov fiber ntau ntau dua tam sim no qis dua tus nqi rov qab tom qab.
