Yog tias koj tau tsaws ntawm no, tej zaum koj yuav tob rau hauv qhov chaw tsim kho cov ntaub ntawv lossis hloov kho dua tshiab thiab pom tau tias - tej zaum yuav lig me ntsis - tias kev xa khoom MPO thaj cords yog messier dua li qhov koj xav. Ncaj ncees txaus. Qhov no tsis zoo li tuavLCconnectors tawm ntawm txee ntawm koj lub zos distributor.
Cov lus teb luv luv (Rau Cov Neeg Hauv Ib Nrab)
Mus nrog cov npe tsim. Corning, CommScope, AFL, Panduit. Lawv raug nqi ntau dua. Lawv ua haujlwm.
Tab sis tsis yog vim li cas koj tseem nyeem, puas yog?
Yog vim li cas qhov no tau yooj yim ceev
MPO connectors tsis yog cables xwb. Lawv yog 8, 12, lossis 24 fibers crammed rau hauv ib yam dab tsi loj ntawm koj tus ntiv tes xoo. Cov pins sib dhos yuav tsum ntaus hauv microns. Lub polarity yuav tsum phim koj cov infrastructure tag nrho. Ib qho yuam kev thiab koj tau txais $ 400 daim ntawv hnyav.
Kuv tau pom cov pab pawg xaj hom B cables thaum lawv cov cassettes xav tau Hom A. Saib xyuas tus kws tshaj lij siv sijhawm peb teev daws teeb meem 40G txuas ua ntej ib tus neeg pom tias cov khoom txuas yog poj niam- poj niam tsis yog txiv neej- poj niam. Cov no tsis yog hypotheticals - qhov no yog hnub Tuesday yav tav su ntawm txhua qhov chaw khaws ntaub ntawv tsim nyog.
Yog li qhov twg koj yuav teeb meem tsawg duaua li caskoj yuav.
Qib 1: Cov Npe Loj
CommScopeua rau InstaPATCH thiab MPOptimate kab. Cov khoom lag luam, lub sijhawm ua haujlwm zoo yog tias koj xaj cov qauv teeb tsa. Lawv SYSTIMAX ULL cov khoom yog qhov zoo tshaj plaws rau kev poob- cov ntawv thov nkag siab. Koj yuav them rau nws.
AFL(lawv muaj lub npe Hyperscale) tsim txhua yam hauv -tsev - fiber ntau, connectors, khoom siv kuaj. Lawv cov hwm MPOs ntaus 0.35 dB qhov poob tsis tu ncua. Cov neeg sib cuag hauv cheeb tsam yeej paub tias lawv tab tom tham txog dab tsi, uas suab yooj yim txog thaum koj tau hais nrog tus neeg muag khoom uas tsis ua.
Corningtsis tshua xav tau kev taw qhia. Lawv EDGE system pib txhais cov ntaub ntawv niaj hnub chaw fiber ntau architecture. Tus nqi qhia txog keeb kwm ntawd.
Panduityog khov. Tsis flashy. Lawv MPO muab kev koom ua ke zoo nrog lawv txoj kev tswj xyuas kab ke dav dav, uas tseem ceeb yog tias koj twb tau siv lawv cov racks thiab tais.
Ntawm no yog qhov hais txog Tier 1 cov neeg xa khoom: koj tsis yog yuav cov cable xwb. Koj tab tom yuav cov ntawv xeem, kev taug qab, thiab ib tus neeg hu thaum yam mus rau sab. Rau kev xa tawm hyperscale, tus nqi ntawd yuav luag ib txwm tsim nyog.
Tuam Tshoj Manufacturers
Kuv yuav ua siab ncaj rau ntawm no vim tsis muaj leej twg xav tau.
Cov tuam txhab xws li UnitekFiber, HOLIGHT, Bonelinks, thiab kaum ob ntawm lwm tus ntawm Alibaba tsim khoom siv tau zoo MPO thaj qaum. Qee tus ntawm lawv tau muab cov khoom dawb - cov ntawv cim npe uas xaus nrog Asmeskas cov npe ntawm nws. Cov chaw ua haujlwm tau txais ISO- ntawv pov thawj. Cov fiber ntau yog Corning iav lawm.
Tus ntes? Kev tswj xyuas zoo sib txawv. Ua yeeb yam.
Kuv tau sim batch los ntawm tib lub Hoobkas uas ib qho khoom xa tuaj ntsuas 0.25 dB poob thiab tom ntej no tuaj ntawm 0.6 dB nrog pom muaj paug ntawm cov ferrules. Tib tus lej, tib daim ntawv xaj, peb lub lis piam sib nrug.
Yog tias koj tab tom yuav Suav ncaj qha:
Xav tau cov ntawv xeem rau txhua lub rooj sib txoos. Tsis yog batch qauv. Txhua. Ib leeg. Ib.

Lub markup yog tiag tab sis tsis outrageous. Qhov tseem ceeb tshaj, tus xa khoom zoo ua haujlwm rov qab los thiab ua cov kev kuaj xyuas zoo uas txuag koj mob taub hau.
FS.com tshwj xeeb tau txais kev txhoj puab heev ntawm tus nqi. Lawv lub tsev- hom MPOs yog tsim nyob rau hauv Suav teb tab sis raug kuaj ua ntej lawv xa los ntawm lawv lub tsev khaws khoom hauv Teb Chaws Asmeskas. Kev lees paub zoo ntawm tus nqi txhoj puab heev - uas yog lawv lub suab tag nrho, thiab rau ntau qhov kev siv nws ua haujlwm.
Dab tsi tiag tiag tseem ceeb thaum xaj
Polarity
Koj yuav tsum paub koj txoj kev polarity ua ntej koj xaj dab tsi. Hom A, Hom B, Hom C - cov no tsis hloov pauv. Tus qauv TIA-568 txhais tag nrho peb, thiab sib xyaw ua ke tsim kev sib txuas uas ua haujlwm hluav taws xob tab sis ua tsis tiav ntawm daim ntawv thov txheej.
Hom B yog qhov feem ntau 40G / 100G parallel optics xav tau. Yog tias koj tab tom ua MPO ncaj qha- rau-MPO kev sib txuas ntawm cov transceivers, qhov ntawd yog qhov koj xav tau. Hom A xav tau cov hlua sib txawv ntawm txhua qhov kawg. Hom C siv khub -flipped trunk cables.
Cov ntaub ntawv koj muaj ua ntej xaj ntau ntxiv. Kuv mob hnyav. Taug kev koj cov racks, tshawb xyuas koj cov cassettes, thiab tsim ib daim ntawv qhia polarity. Ces xaj.
Poj niam los txiv neej
Txiv neej connectors muaj alignment pins. Poj niam connectors tsis. Lawv tsis interchangeable. Feem ntau cov adapters thiab transceivers xav tau ib tug txiv neej connector, uas txhais tau tias koj lub cev cables feem ntau yog poj niam -poj niam nrog pinned adapters nyob rau hauv lub panels.
Tau qhov no tsis yog lawm thiab koj yuav tsis tuaj yeem txuas tau txhua, lossis koj yuav rhuav tshem cov pins sim yuam cov poj niam txiv neej tsis sib haum ua ke. Pom nws tshwm sim.
Fiber suav thiab hom
8- fiber ntau rau QSFP + (40G) thiab qee qhov 100G daim ntawv thov. 12- fiber ntau rau kev siv MPO ib txwm siv. 24- fiber ntau rau ntau dua 100G thiab 400G.
Tib -mode (OS2, G.657.A1) rau ntev ncav cuag thiab yoj- faib multiplexing. Multimode OM3 rau legacy 10G / 40G. OM4 rau kev xa tawm niaj hnub mus txog 150 meters ntawm 100G. OM5 yog tias koj tab tom npaj SWDM lossis tsuas yog xav tau yav tom ntej - pov thawj.
Cov neeg yuav khoom feem ntau ua rau OM4 rau hauv - kev txuas hauv tsev thiab ib qho - hom rau tsev kawm ntawv lossis DCI daim ntawv thov. Qhov ntawd feem ntau yog lawm.
Cov Lus Nug Loss Insertion
Zoo MPO sib dhos lub hom phiaj 0.35 dB ib khub niam txiv. Cov pheej yig yuav spec 0.5 dB lossis siab dua. Hauv peb qhov kev sib txuas ntawm -, qhov sib txawv ntawd.
Koj cov nyiaj tau los ntawm cov transceiver raug kho. Hlawv nws ntawm cov khoom sib txuas tsis zoo thiab koj tau ua kom koj qhov siab tshaj plaws ncav cuag lossis tua koj cov npoo tag nrho . 40G SR4 muab rau koj txog 1.5 dB tag nrho - txhua feem kaum ntawm qhov teeb meem dB.
Hwm -qib connectors los ntawm US Conec (MTP Elite) ntaus 0.15 dB ib txwm. Lawv kim. Rau lub hom phiaj- lub cev tseem ceeb, lawv tsim nyog xav txog.
Qhov chaw kuv yuav tau xaj los ntawm
Rau kev xa tawm ntau lawm hauv kev lag luam lossis hyperscale:
AFL ncaj qha (tshwj xeeb yog tias koj xav tau kev cai ntev lossis ntim siab)
CommScope los ntawm koj li kev sib txuas lus VAR
Corning yog tias koj twb nyob hauv lawv cov ecosystem
Rau kev sim, kev ua haujlwm, lossis tus nqi -sensitive ntau lawm:

Alibaba cov chaw muag khoom nrog kev kuaj xyuas muaj peev xwm
Ua-hauv-Tuam Tshoj cov tuam txhab pov thawj
Tau cov qauv ua ntej. Kuaj lawv tus kheej.
Qhov Kev Xeem
Tsis muaj leej twg xav tham txog qhov no, tab sis koj xav tau cov cuab yeej kuaj ua ntej koj xav tau cables. Lub ntsuas hluav taws xob kho qhov muag thiab lub teeb pom kev tsawg kawg nkaus. Lub microscope ntsuas rau MPO tshuaj xyuas - 200x lossis 400x units nrog MPO- cov lus qhia tshwj xeeb.
80% ntawm MPO teeb meem yog kis kab mob. Pom pom av, tsis pom zaj duab xis, khawb los ntawm cov matings yav dhau los. Yog tias koj tsis tuaj yeem tshawb xyuas koj cov khoom sib txuas, koj ya dig muag.
Cov tuam txhab xws li Fluke Networks ua rau MultiFiber Pro tshwj xeeb rau kev sim MPO. VIAVI muaj SmartClass MPOLx kab. Cov no tsis pheej yig, tab sis lawv tig "lub network qeeb thiab kuv tsis paub yog vim li cas" rau hauv "fiber txoj hauj lwm 7 muaj 0.9 dB insertion poob vim muaj kab mob."
Ntxuav ua ntej txhua mating. Tshawb xyuas tom qab txhua qhov huv. Qhov ntawd tsis yog paranoia - yog li cov kws tshaj lij ua haujlwm.
Kuv Cov Lus Pom Zoo
Pib nrog ib qho kev txiav txim me me los ntawm ob tus neeg muag khoom sib txawv. Tib specs, tib fiber ntau suav. Ntsuam xyuas lawv ib leeg. Ntsuas qhov poob qis, xyuas cov polish zoo, xyuas qhov polarity.
Tom qab ntawd ntsuas nrog leej twg ua tau zoo dua.
Kev lag luam hauv cov ntaub ntawv yog littered nrog cov kws tshaj lij uas pom qhov chaw pheej yig, xaj 500 cables, thiab pom tias 30% ntawm lawv ua tsis tiav kev tshuaj xyuas. Tsis txhob ua li ntawd.
Cov neeg muag khoom hwm yog hwm rau qhov laj thawj. Cov neeg siv nyiaj txiag tuaj yeem ua haujlwm, tab sis tsuas yog tias koj txheeb xyuas. Tsis muaj noj su dawb ntawm no.
Tsuas yog tsis txhob xaj hnub ua ntej koj xa mus rau qhov xav tau txuj ci tseem ceeb. Lub sijhawm txhuas yog tiag tiag, thiab cov khoom zoo siv sijhawm los tsim khoom.
Qhov no tsis yog cov ntsiab lus txhawb nqa. Kuv tsis muaj kev sib raug zoo nrog ib qho ntawm cov tuam txhab hais. Cov no yog cov kev soj ntsuam los ntawm kev xa tawm tiag tiag, uas yog vim li cas lawv ntxhov thiab tsis tuaj nrog cov lus pom zoo huv si thaum kawg.
