Kuv tau nyob hauv data center cabling rau yuav luag kaum ib xyoos tam sim no thiab cov lus nug no los tas li. Txhua tus neeg saib xyuas kev yuav khoom, txhua tus thawj coj IT xav paub: peb puas yuav tsum ua raws li peb cov txheej txheem LC uas twb muaj lawm lossis mus rau tag nrho - hauv MPO? Thiab tshwj xeeb tshaj yog- yuav ua li cas thaum koj xav tau txuas ob lub ntiaj teb?Cov lus teb luv luv yog yog. Tab sis qhov ntawd tsis muaj txiaj ntsig tiag tiag, puas yog.
Qhov xwm txheej tiag neeg feem coob ntsib
Nov yog qhov kuv pom ntau dhau. Ib lub tuam txhab tsim lawv cov ntaub ntawv chaw tsib, tej zaum yim xyoo dhau los. Txhua yam khiav ntawm LC duplex. Ua haujlwm zoo. Tom qab ntawd lawv pib xa 40G lossis 100G hloov pauv, tej zaum qee qhov chaw cia khoom tshiab, thiab tam sim ntawd lawv tab tom ntsia ntawm QSFP cov chaw nres nkoj uas xav tau MPO-12 txuas.
Yog li koj ua dab tsi?
Rip txhua yam tawm thiab pib dua? Tsis muaj leej twg muaj peev nyiaj rau qhov ntawd. Kev thauj mus los ib leeg yuav khiav mus rau ntau pua txhiab tus nyob ntawm koj qhov hneev taw, thiab qhov ntawd yog ua ntej koj suav nrog cov nqi poob qis uas -ua siab ncaj- feem ntau lub tuam txhab nyiaj txiag tseem tsis suav nrog. Kuv tau pom kev tsiv teb tsaws chaw hais txog $ 400K uas tau xaus rau sab qaum teb ntawm $ 1.2 lab thaum koj suav nrog cov khoom lag luam poob thiab ua haujlwm dhau sijhawm.
MPO rau LC hloov dua siab tshiab cables nyob precisely rau qhov teeb meem no.
Tej yam no ua tiag tiag
IbMPO to LWDbreakout cable (qee zaus hu ua lub sam xauv nees lossis fanout cable) siv ib qho MPO-12 lossis MPO-24 txuas ntawm ib kawg thiab faib nws mus rau ib tus neeg LC duplex khub ntawm lwm tus. 12-fiber version muab rau koj 4 duplex channels. 24-fiber version muab rau koj 12.
Qhov ntawd yog nws. Qhov ntawd yog tag nrho cov khoom.
Tab sis tus nqi cuam tshuam khiav tob dua li ntawm kab nws tus kheej.
Qhov Txiaj Ntsig Los Ntawm
Koj Cov LC Patch Panels uas twb muaj lawm nyob
Qhov no loj heev. Cov LC thaj vaj huam sib luag koj yuav? Lawv tseem ua haujlwm. Koj cov kab ke sib txuas ntawm cov racks? Tseem ua haujlwm. Tag nrho cov fiber ntau uas koj tau khiav hauv pem teb lossis cov tais nyiaj siv ua haujlwm? Kwv yees dab tsi - tseem ua haujlwm.
Kuv tau ua haujlwm nrog lub tuam txhab kev noj qab haus huv xyoo tas los - nruab nrab - lub tsev kho mob loj, plaub qhov chaw- thiab lawv tau suav tias lawv yuav tau siv kwv yees li $ 180,000 tsuas yog rau kev hloov LC vaj huam sib luag yog tias lawv mus puv MPO. Los ntawm kev siv breakout cables ntawm cov cuab yeej kawg nkaus xwb, lawv khaws lawv cov vaj huam sib luag thiab tsuas yog siv ib ncig ntawm $ 12,000 ntawm kev hloov pauv cables lawv tus kheej.
Qhov ntom ntom qhov twg koj xav tau tiag tiag
Nov yog qee yam ntawm cov ntawv muag muag tsis tas yuav piav qhia zoo.
Koj xav tau MPO qhov ntom ntom ntawm cov khoom siv kawg. Qhov ntawd yog qhov chaw nres nkoj kim thiab qhov chaw nruj. Hauv patching txheej? LC zoo. LC yog qhov yooj yim ua haujlwm nrog rau feem ntau cov thev naus laus zis. Lub polarity yog yooj yim dua. Cov connectors muaj kev zam txim ntau dua. Thiab thaum ib yam dab tsi tawg -vim ib yam dab tsi ib txwm tawg- koj tab tom hloov $ 15 LC thaj qaum es tsis yog $80 MPO sib dhos.
Kev cob qhia nqi tsis muaj leej twg hais txog
Txhua zaus kuv nqa cov nqi cob qhia hauv lub rooj sib tham, tib neeg saib kuv zoo li kuv tab tom ua khoom. Tab sis MPO connectors yuav tsum tau ceev faj ntxiv. Lub ntsej muag kawg muaj 12 lossis 24 cov lus qhia fiber ntau uas yuav tsum tau ua kom huv. Kev kis kab mob yog tus thib ib ua rau muaj teeb meem kho qhov muag thiab MPO endfaces yog 12 zaug nyuaj dua los ntxuav dua LC.
Koj cov kws tshaj lij uas tau ua LC tau kaum xyoo xav tau kev cob qhia. Lawv xav tau cov cuab yeej tshuaj xyuas tshiab. Lawv xav tau cov khoom siv tu sib txawv. Ib qho kev soj ntsuam MPO tsim nyog yog $3,000-5,000. Tej zaum koj twb muaj LC scopes dag ib ncig.
Lo nrog LC ntawm txheej txheej thiab koj zam feem ntau ntawm qhov no.
Qhov Lej Uas Tseem Ceeb
Okay cia kuv ua haujlwm dhau ntawm qhov xwm txheej. Hais tias koj muaj kab ntawm cov txee, 10 racks, txhua tus nrog ToR hloov khiav 4 x 40G uplinks. Qhov ntawd yog 40 MPO kev sib txuas ntawm sab hloov
Tag Nrho MPO Txoj Kev:
40 x MPO-12 lub cev cables @ $120 txhua=$4,800
MPO thaj vaj huam sib luag (xav tias koj tsis muaj lawv)=$6,000-8,000
Kev cob qhia/ cuab yeej=$5,000 ish
Kev hloov tsis tu ncua raug nqi siab dua
Tag nrho thawj zaug: kwv yees li $16,000+
MPO-rau-LC Breakout Approach:
40 x breakout cables @ $75 txhua=$3,000
Siv LC panels uas twb muaj lawm=$0
Kev cob qhia=tsawg heev
Tag nrho pib: nyob ib ncig ntawm $3,000
Cov lej hloov pauv nyob ntawm qhov ntev ntawm cable, tus nqi muag khoom, txo ntim ntim. Tab sis qhov ratio nyob twj ywm zoo ib yam. Breakout cables raug nqi tsawg dua thiab ua haujlwm tsawg dua.
Thaum qhov no tsis ua haujlwm
Kuv yuav tsum ncaj ncees ntawm no.
Yog tias koj tab tom tsim greenfield-brand tshiab facility, khoob hauv pem teb- ces tus lej hloov. Mus rau MPO haiv neeg thoob plaws yuav ua rau muaj kev nkag siab zoo. Koj tau txais kev ceev zoo dua hauv koj lub cev, kev xa mus sai dua thaum koj tau kawm pab pawg, thiab koj tau teeb tsa rau yav tom ntej nrawm.
Tsis tas li ntawd yog tias koj tab tom khiav cov ntawv thov kev sib txuas ua ke uas koj xav tau tiag tiag 12 fibers nqa tsheb ib txhij, cov kab hluav taws xob tawg tsis yog cov lus teb. Koj yuav xav tau MPO kom raug-rau-MPO ntawm qhov ntawd.
Thiab yog lawm, qee lub tuam txhab tau pib saib 400G thiab dhau qhov uas MPO-16 nkag mus rau hauv daim duab. Tsi txawv tsiaj kiag li.
Tab sis feem coob ntawm cov neeg nug cov lus nug no? Lawv tsis nyob hauv cov xwm txheej ntawd. Lawv tab tom khiav kev sib xyaw ntawm 10G thiab 40G nrog qee qhov 100G nkag mus rau hauv, lawv muaj cov txheej txheem uas twb muaj lawm lawv tsis tuaj yeem pov tseg, thiab lawv xav tau txoj hauv kev ua tau zoo rau pem hauv ntej.
Qhov Polarity
Kuv tsis tau mus rau hauv qhov no tab sis kuv paub tias ib tug neeg yuav nug.
MPO connectors tuaj nyob rau hauv txawv polarity configurations -Hom A, hom B, hom C-thiab yog hais tias koj tsis phim koj breakout cables rau koj lub cev cables, koj yuav tau hla khub. Teeb tuaj tab sis tsis muaj dab tsi ua haujlwm. Txaus siab heev los daws teeb meem yog tias koj tsis paub dab tsi koj tab tom nrhiav.
Thaum txiav txim breakout cables, paub meej tias cov polarity phim koj ib puag ncig. Los yog yog tias koj tsis paub meej, Hom B yog hom ntawm lub neej ntawd rau feem ntau 40G / 100G xa tawm siv cov khoom sib txuas. Tab sis ncaj ncees tsuas yog nug koj tus neeg muag khoom. Lawv daws qhov no txhua hnub.
Kev txiav txim siab zoo
Tsis yog tag nrho cov breakout cables yog tsim sib npaug. Cov pheej yig ntawm Amazon? Kuv twb sim lawv. Txog 30% muaj qhov poob qis tshaj qhov tshwj xeeb tawm ntawm lub hnab. Rov qab los yog npau suav phem. Kev them nyiaj yug tsis muaj nyob.
Rau qhov chaw tsim khoom, yuav los ntawm cov neeg muag khoom tsim fiber ntau. FS, Corning, CommScope, Panduit- lawv txhua tus ua lawv. Tus nqi sib txawv yog tej zaum 20-30% ntau dua li cov kev xaiv sketch thiab koj tau txais kev tswj xyuas zoo thiab kev txhawb nqa tiag tiag thaum muaj tej yam tsis raug.
Qhov no tseem ceeb tshaj qhov koj xav. Qhov tsis zoo ntawm cov kab hluav taws xob uas siv 40G txuas tuaj yeem raug nqi ntau dua hauv lub sijhawm daws teeb meem tshaj li qhov koj khaws cia pheej yig hauv thawj qhov chaw.
Ib qho ntxiv
Kuv pheej pom cov kab lus uas kho qhov no tsuas yog kev sib tham txog nqi xwb. Thiab yog, qhov ntawd yog qhov lus cog tseg. Tab sis muaj ib tug kev ntseeg siab ib yam nkaus thiab.
Txhua qhov kev sib txuas yog ib qho kev ua tsis tiav. Txhua MPO mating yog 12 txoj hauv kev rau kev sib kis tsis yog 1. Thaum koj siv cov kab hluav taws xob tawg thiab tuav LC ntawm koj cov txheej txheej, koj yuav txo tau MPO matings hauv txoj kev teeb liab. Koj lub cev mus MPO-rau-MPO ntawm qib txuas mus tas li (tso nws thiab tsis nco qab), tab sis koj thaj ua rau thaj- tej yam uas tau kov tas li- nyob LC.
Tsawg kov ntawm MPO=teeb meem tsawg dua.
Kab hauv qab
Rau feem ntau ntawm kev lag luam ib puag ncig nrog LC infrastructure uas twb muaj lawm, MPO rau LC breakout cables muab cov nqi txo qis piv rau kev lag luam wholesale mus rau MPO. Cov kev txuag nyiaj thaum koj ua kom tsis txhob muaj kev hloov pauv vaj huam sib luag, txo cov kev xav tau ntawm kev cob qhia, kev ua haujlwm yooj yim dua, thiab cov nqi hloov pauv qis dua lub sijhawm.
Lub tshuab ua haujlwm. Kev lag luam ua haujlwm. Tsuas yog yuav cov kab hluav taws xob zoo thiab them nyiaj rau polarity.
Qhov ntawd yog txhua yam muaj rau nws.
