Yog tias koj tau nyob rau hauv cov ntaub ntawv chaw ua si ntev txaus, tej zaum koj yuav tau ntsia ntawm lub tais cable uas ntws nrog ib tus neeg ua haujlwm fiber ntau thiab xav tias- yuav tsum muaj txoj hauv kev zoo dua. Muaj.MPO kab. Tab sis ntawm no yog qhov tsis muaj leej twg qhia koj ua ntej: lawv tsis yog ib txwm hu txoj cai.
Cov lus teb luv (Ua ntej peb dhia hauv)
Siv MPO thaum koj tab tom cuam tshuam nrog cov teeb meem ceev, hloov kho kom nrawm, lossis koj tsuas yog mob ntawm kev tswj tus kheej cov hlua txuas ib los ntawm ib qho. Tsis txhob siv nws rau qhov chaw ua haujlwm me me lossis thaum koj cov peev nyiaj qw rau koj txhua zaus koj saib cov nqe lus.
Qhov ntawd yog oversimplified, obviously. Cia kuv rhuav tshem.
High-Density Ib puag ncig-Qhov no yog qhov chaw MPO ci
Cov chaw zov me nyuam. Hyperscale chaw. Cov chav tsev neeg rau zaub mov uas qhov chaw khib nqi ntau dua ib square feet dua li Manhattan vaj tsev. Cov no yog MPO thaj chaw.
Thaum koj tab tom cramming 40G, 100G, lossis 400G kev sib txuas rau saum- ntawm -Rack keyboards, khiav kaum ob cais LC duplex cables pib saib tsis zoo. MPO lub cev cable ua li cas kaum ob lub cables ua-ib qho txuas, ib rub, ua tiav. Qhov chaw txuag ib leeg ua rau qhov hloov pauv rau feem ntau ntawm kev ua haujlwm siab tshaj qhov ntsuas.
Kuv tau pom cov chaw txiav lawv cov cable ntim ntau dua 60% tom qab tsiv mus rau MPO-raws li cov cabling. Airflow txhim kho. Cov nqi cua txias poob. Cov kws kho mob tau tso tseg lawv lub siab thaum lub sijhawm txav chaw - ntxiv - hloov pauv.
Tab sis -thiab qhov no tseem ceeb- yog tias koj ib puag ncig muaj tsawg dua, hais, 48 qhov chaw nres nkoj rau ib lub khib? Tej zaum tsuas yog lo nrog tsoos patching. Cov nyiaj siv ua haujlwm ntawm MPO cassettes thiab kev kawm nkhaus rau koj pab neeg yuav tsis them.
Kev hloov kho ceev: 40G / 100G / 400G thiab Tshaj
Ntawm no yog qhov uas nws tau nthuav.
40GBASE-SR4 siv plaub fibers kis, plaub tau txais. 100GBASE-SR4 ua tib yam ntawm qhov nrawm dua. 400GBASE-SR16 thawb kaum rau txoj kab sib luag. Koj pom tus qauv? Parallel optics xav tau ntau-fiber connectors. Qhov ntawd yog qhov uas MPO tau tsim los rau.
Yog tias koj tseem tab tom khiav 10G txhua qhov chaw thiab tsis muaj kev npaj yuav hloov kho, MPO yog overkill. Lub sijhawm. LC duplex tuav 10G zoo xwb.
Tab sis lub sijhawm koj daim ntawv qhia kev muaj xws li 40G keyboards, QSFP + transceivers, lossis ib yam dab tsi nrog "parallel" hauv daim ntawv spec- pib xav MPO. Retrofitting tom qab raug nqi ntau dua li ua nws yog thawj zaug. Cia siab rau kuv ntawm qhov no.
Daim ntawv ceev ceev ntawm Transceivers
Tsis yog txhua tus transceivers ua si zoo nrog txhua MPO configurations. 8-fiber vs 12-fiber kev sib cav? Nws yog tiag tiag, thiab nws tseem ceeb . 40G QSFP + SR4 siv 8 fibers (4Tx/4Rx). Tab sis 100G CFP SR10 xav tau 20 fibers. Kev suav cov fiber ntau tsis sib xws txhais tau hais tias cov khoom siv hloov pauv, hloov pauv hloov, lossis cov cores khib nyiab zaum tsaus hauv koj lub cev.
Xyuas koj cov transceiver specs ua ntej xaj cables. Zoo li pom tseeb, tab sis koj yuav xav tsis thoob ntau npaum li cas qhov no tau raug saib xyuas.
Rapid Deployment Projects
Tau txais cov ntaub ntawv tshiab los hauv online hauv rau lub lis piam? Kev txiav tawm ntau pua ntawm fiber ntau xaus tsis tshwm sim. Tsis huv, txawm li cas los xij.
Ua ntej-MPO cov rooj sib tham txiav tawm daws qhov no. Factory-ua, Hoobkas- kuaj, xa tuaj rau ntsaws. Koj pab neeg txhim kho rub cov kab hauv lub cev, snaps cassettes rau hauv vaj huam sib luag, thiab txav mus. Yam dab tsi siv rau hnub yuav siv sij hawm teev.
Kev lag luam - tawm? Tsawg zog. Ua ntej- ncua ntev txhais tau tias koj tab tom cog lus rau qee qhov kev ncua deb. Txiav txim tsis ncaj ncees lawm thiab koj nyob nraum coiling tshaj cable tom qab khib los yog tuaj luv luv. Ntsuas ob zaug, xaj ib zaug.
Thaum tsis siv MPO
Qhov no feem ntau tau glossed nyob rau hauv cov ntaub ntawv tsim khoom (shocking, txoj cai?). Tab sis muaj cov xwm txheej raug cai uas MPO yog qhov kev xaiv tsis raug.
Cov me me -scale deployments: Hauv qab 24 chaw nres nkoj? Txheem LC / SC patching ua haujlwm zoo. Tus nqi hwm ntawm MPO kho vajtse yuav tsis xa cov ntsiab lus ROI.
Kev khiav ntev heev: MPO kev sib txuas qhia txog kev poob qis- feem ntau nyob ib ncig ntawm 0.35dB ib khub rau cov khoom zoo, qee zaum siab dua rau cov pheej yig. Ntawm qhov ntev - cov kab txuas txuas uas txhua feem kaum ntawm dB suav, cov ntsiab lus txuas ntxiv cuam tshuam rau koj. Direct fusion splices los yog tsawg dua connectors tej zaum yuav ntse dua.
Cov peev nyiaj- txwv cov haujlwm: Cia peb ua siab ncaj. MPO trunk cables, cassettes, adapters-lawv raug nqi ntau dua li cov kab txuas ib txwm muaj. Yog tias cov txiaj ntsig ceev thiab ceev tsis siv rau koj qhov xwm txheej, koj tau them tus nqi hwm rau cov peev txheej uas koj yuav tsis siv.
Cov cuab yeej cuab tam qub: Khiav iav uas tsuas lees txais LC/SC? Koj yuav xav tau breakout cables lossis cassettes los hloov. Cov khoom siv ntxiv, kev poob ntxiv, tus nqi ntxiv. Qee lub sij hawm ua kom tag nrho cov khoom yooj yim ntaus chasing marginal optimization.
Multi-Mode vs Single-Mode: Yog, Nws Hloov Yam
MPO ua haujlwm nrog ob qho tib si, tab sis cov kev siv sib txawv.
Multi-mode (OM3/OM4/OM5) dominates nyob rau hauv -building thiab data center applications. Shorter nrug, txo tus nqi transceiver, yooj yim sib dhos tolerances. Feem ntau 40G/100G parallel optics deployments siv ntau-mode OM4 MPO.
Tib - hom MPO muaj nyob rau qhov ntev dua thiab siab dua qhov yuav tsum tau muaj bandwidth. 400G-ZR, coherent optics, lub hauv paus tsev kawm ntawv rov qab ua haujlwm-ib zaug- hom thaj chaw. Tab sis ntawm no yog qhov ntes: ib zaug - hom MPO xav kom nruj dua. Cov connectors raug nqi ntau dua. Kev ntxuav tseem ceeb ntau dua (ntau ntxiv tom qab). random insertion poob teeb meem uas yuav tsis faze ib tug multi-mode link tuaj yeem tua ib zaug -mode ib.
Yog tias koj daim ntawv thov yog intra-rack lossis intra- kab txuas hauv qab 100 meters, ntau- hom MPO tej zaum yuav ua rau muaj kev nkag siab zoo. Hla -lub tsev lossis ib yam dab tsi mus txog qhov kev txwv deb? Ntsuas ib qho - hom kom zoo.
Cov lus nug Polarity
Tsis muaj leej twg xav tham txog polarity txog thaum ib yam dab tsi tsis ua haujlwm. Tom qab ntawd txhua leej txhua tus dheev tus kws tshaj lij.
MPO cables tuaj nyob rau hauv peb hom polarity: A, B, thiab C. Tag nrho cov kab ke- pob tw, patch cords, adapters -yuav tsum tswj kom muaj kev sib kis zoo- mus rau - tau txais kev sib tw kawg- mus rau - kawg. Ntxo qhov no thiab koj qhov txuas tsis ua haujlwm lossis ua haujlwm tsis tu ncua (tsawg dua, ncaj ncees).
Hom A cables ncaj nraim -los ntawm ib tus yuam sij - nce thiab ib tus yuam sij - down connector. Hom B cables muaj ob lub connectors taw qhia tib txoj kev, thim rov qab txoj haujlwm fiber ntau. Hom C flips nyob ib sab khub.
Feem ntau cov ntaub ntawv chaw teeb tsa cabling specs tswj cov txheej txheem polarity. TIA-568 txhais peb txoj kev sib txuas (tsis meej pem kuj hu ua A, B, thiab C) uas siv cov kev sib txawv ntawm cov cables. Tau txais qhov tsis ncaj ncees lawm txhais tau tias kev daws teeb meem cov sij hawm noj mov.
Kuv lub tswv yim? Xaiv ib txoj kev polarity, sau nws obsessively, thiab lo rau nws thoob plaws koj cov infrastructure. Kev sib xyaw ua ke hauv tib qhov chaw caw chaos.
Tswvyim Deployment Scenarios
Cia kuv muab qee qhov piv txwv ntawm -world.
Scenario 1: Tshiab 400G Kab laug sab-Nplooj ntaub
Koj tab tom tsim tus txha nraub qaum- nplooj architecture nrog 400G- muaj peev xwm hloov pauv. Txhua tus txha nraub qaum txuas mus rau txhua nplooj. Dense port counts, short cable runs, parallel optics transceivers.
Siv: 8-fiber lossis 16- fiber ntau MPO lub cev cables ntawm qaum thiab nplooj kab. Pre-terminated assemblies matched rau koj rack layout. Cov khoom sib txuas zoo nrog IL hauv qab 0.35dB.
Scenario 2: Enterprise Campus Backbone
Main faib ncej txuas peb lub tsev. Kev ncua deb ntawm 80 mus rau 300 meters. Sib tov ntawm 10G thiab 40G uplinks.
Siv: Hybrid txoj kev. Tib - hom MPO rau 40G txoj kev; txheem LC duplex rau 10G. Thaum lub sij hawm, raws li 10G cov cuab yeej muaj hnub nyoog, tsiv cov kev mus rau MPO. Tsis txhob yuam txhua yam ib zaug.
Scenario 3: Colocation Txee
Koj xauj ib lub txee rau hauv ib lub colo. Yim lub servers, ob lub keyboards, hla - txuas mus rau qhov sib ntsib -kuv chav.
Tsis txhob siv MPO: Overkill. LC patch cords ua haujlwm zoo. Txuag koj cov nyiaj rau ib yam dab tsi tseem ceeb.
Kev ntxuav thiab tshuaj xyuas: Tsis yog -Ngotiable
Ntu no yuav tsis ntev, tab sis nws tseem ceeb heev.
MPO connectors muaj 8, 12, 16, lossis 24 fiber ntau lub ntsej muag ntim rau hauv ib lub ferrule. Txhua lub ntsej muag yog qhov muaj peev xwm ua tsis tiav. Plua plav, roj, khawb- tej yam kab mob uas yuav cuam tshuam rau ib leeg xwb - fiber ntau LC connector tau txais kev nthuav dav thaum koj tau txais ob lub kaum ntse ntse los txhawj txog.
Tshawb xyuas ua ntej mating. Txhua lub sijhawm. Siv cov khoom siv fiber ntau nrog MPO adapter. Yog tias qias neeg, ntxuav siv lub cassette-style cleaner (nyiam dua ntxuav). Re- tshuaj xyuas. Yog tias tseem qias neeg, sim ua kom ntub dej tom qab ziab.
Hla cov kauj ruam no ntawm koj qhov xwm txheej. Kuv tau pom tag nrho cov kab hluav taws xob tsis lees paub ntawm kev lees paub vim tias ib tus neeg kov lub ferrule thaum lub sijhawm teeb tsa. Ib tug ntiv tes tuaj yeem rhuav tshem kaum ob fibers.
Tus nqi txiav txim siab-Ua tiag tiag
Ua ntej, MPO systems raug nqi ntau dua qhov sib npaug LC-raws li infrastructure. Cov connectors yog precision Cheebtsam. Lub Hoobkas txiav tsis pheej yig. Cassettes, adapter vaj huam sib luag, siab -cov ntaub ntawv ntom ntom- nws ntxiv.
Tab sis tag nrho cov nqi ntawm cov tswv cuab qhia ib zaj dab neeg sib txawv rau kev xa tawm loj. Kev txhim kho sai dua txhais tau tias tus nqi zog qis dua. Qhov ceev dua txhais tau tias tsawg dua racks thiab tsawg dua qhov chaw hauv pem teb. Kev ua haujlwm MAC yooj yim dua txhais tau tias txo cov nuj nqis ua haujlwm tsis tu ncua.
Lub breakeven point txawv ntawm qhov chaw. Rau cov chaw khaws ntaub ntawv khiav 100+ siab- cov chaw nres nkoj ceev, MPO feem ntau yeej dhau 3-5 xyoo qab ntug. Rau me me deployments, tej zaum yeej tsis.
Khiav tus lej rau koj qhov xwm txheej tshwj xeeb. Tsis txhob ntseeg kev lag luam xwb.
Kev xav zaum kawg
Yog li thaum twg koj yuav tsum siv MPO fiber optic cable?
Thaum koj scaling. Thaum koj xav tau ceev. Thaum uas tig mus optics dominate koj hardware roadmap. Thaum installation ceev tseem ceeb tshaj li cov nqi ntawm cov khoom. Thaum tswj tus kheej fiber ntau khiav tau ua haujlwm tsis ruaj khov.
Thaum twg koj yuav tsum tsis txhob? Ib puag ncig me me. Kev txwv nyiaj txiag heev. Legacy-dominated infrastructure uas tsis muaj kev txhim kho. Ntev - qhov deb txuas qhov twg txhua decibel suav.
Nws yog ib qho cuab yeej. Ib tug zoo. Tab sis zoo li txhua yam cuab yeej, nws ua haujlwm zoo tshaj plaws thaum sib phim rau txoj haujlwm zoo.
