MTP vs MPO Cable: Dab tsi yog qhov txawv thiab xaiv qhov twg?

Kuv tau ua kev muag khoom ntawm FOCC tau tsib xyoos tam sim no, thiab kuv cuam tshuam nrog MTP / MPO tsis meej pem tej zaum peb lossis plaub zaug hauv ib lub lis piam. Kev ua lag luam tau ua rau muaj kev ntxhov siab ntawm ob nqe lus no. Qee cov neeg siv khoom hais txog "MTP tiag" tab sis lawv cov peev nyiaj tsis tuaj yeem kov US Conec tus nqi. Lwm tus mus pheej yig ntawm tsis muaj -npe MPO, ces lawv qhov txuas 400G yuav tsis tuaj, thiab lawv hloov peb lub transceivers ua ntej pom cov connector IL drifted rau 0.8dB.

Yog li kuv xav kom tshem tawm qhov no. Tsis yog phau ntawv sib piv, tab sis qhov peb tau kawm los ntawm kev muag cov khoom no thiab pab cov neeg siv khoom daws teeb meem. Tej zaum kuv muaj qee qhov kev tsis ncaj ncees vim peb yog tus neeg muag khoom ib yam nkaus, tab sis kuv yuav sim ua ncaj ncees nrog koj.

MTP Vs MPO Cable: What's The Difference And Which To Choose?

Lus Teb luv luv

Yog tias koj maj nrawm:

MPO yog tus qauv qhib (IEC 61754-7). Leej twg tuaj yeem ua tau. MTP yog US Conec lub npe lag luam. Kev ua tau zoo tiag tiag zoo dua, tab sis tus nqi yog siab dua.

Lawv lub cev sib xws, lawv yuav ua phooj ywg ua ke. Tab sis qhov sib txawv ntawm kev ua tau zoo yuav tom koj hauv 400G + daim ntawv thov. Rau 10G / 40G, ncaj ncees qhov txawv yog tsawg. Yog tias koj cov peev nyiaj nruj, yuav MPO hauv tsev zoo los ntawm qhov chaw muaj koob npe thiab tsis txhob cia qee tus neeg muag khoom muag koj ntawm MTP koj tsis xav tau.

OK, cov ntsiab lus hauv qab no.

Koj Yuav Tsum Tau Paub Txog US Conec

Tsis tuaj yeem tham txog MTP yam tsis tau tham txog US Conec, tab sis ntau tus neeg yuav khoom tsis paub lub tuam txhab txoj haujlwm no hauv kev lag luam.

US Conec yog tus tuav lub ntsiab ntawm MT ferrule technology. Lawv tau sau npe MTP cov cim lag luam hauv xyoo 1996. Lwm cov tuam txhab lag luam uas xav ua kom siab -Kev ua tau zoo MPO connectors yuav tsum tau ua haujlwm nyob ib puag ncig lawv cov patents (nyuaj) lossis tau txais daim ntawv tso cai (kim). Tias yog vim li cas koj pom cov khoom sau npe "MTP- sib xws" lossis "MTP sib npaug" lossis tsuas yog "High Performance MPO." Lawv tag nrho cov seev cev nyob ib ncig ntawm txoj cai.

Feem ntau ntawm lawv txoj kev tiv thaiv patent yuav tas sijhawm ntawm 2024-2026. Hauv kev xav, kev lag luam qhib tom qab ntawd. Tab sis kev paub txog kev tsim khoom tsis tau them tag nrho los ntawm patents. US Conec cov txheej txheem kev txawj ntse yog tiag tiag.

MPO Push-pull Boot Connector

Vim li cas qhov no tseem ceeb? Vim hais tias thaum koj nyob nraum speccing connectors, koj yuav tsum to taub tias "MTP" tsis yog ib tug ua tau zoo tier. Nws yog ibhom kev lag luam monopoly. Kev qhia MTP txhais tau hais tias US Conec (lossis puv ntawm cov tuam txhab uas lawv tau tso cai). Yog tias koj qhov spec nruj dhau lawm, koj tsuas tuaj yeem tau txais ib lossis ob tus neeg sib tw, thiab tom qab ntawd kev sib tham tus nqi tawm ntawm lub qhov rais.

Peb ua dab tsi ntawm FOCC: yog tias tus neeg siv khoom daim ntawv thov tiag tiag xav tau Elite- theem kev ua tau zoo (0.15dB ib txwm IL thaj chaw), peb pom zoo rau US Conec thawj lossis Senko tus nqi hwm kab. Yog tias nws yog 100G lossis qis dua, tsis yog super poob-sensitive, peb muaj peb tus kheej siab - kawg MPO cov khoom kab. Kev ua tau zoo specs mus txog MTP tus qauv tab sis tus nqi qis dua 40%. Txoj kev twg mus yog nyob ntawm seb koj cov peev nyiaj txuas puas ua haujlwm.

Technical Differences: Dab tsi tiag tiag vs Kev Lag Luam

Yim tawm ntawm kaum MTP vs MPO kev sib piv hauv online tsuas yog luam ib leeg xwb. Cia kuv qhia koj qhov peb tau sim tiag tiag:

Floating Ferrule

Qhov no yog qhov tseeb. US Conec tus tsim cia lub ferrule txav me ntsis nyob rau hauv lub vaj tse, tus kheej -aligning thaum mating. Tsis tu ncua MPO ferrules yog tsau. Yog hais tias muaj ib qho micro-misalignment ntawm ob fiber ntau arrays, qhov ruaj khov tsim quab yuam nws, thiab poob mus.

Peb tau ua qhov kev sib piv. Tib fiber ntau batch, tib txheej txheem txiav. Floating ferrule random mating poob khiav txog 0.1-0.15dB qis dua qhov ruaj khov. Tsis zoo li ntau, tab sis pawg plaub lossis tsib cov ntsiab lus txuas thiab nws ntxiv.

Qhia Pin Khoom thiab Zoo

US Conec siv stainless hlau pins nrog cov lus qhia elliptical. Hnav tsis kam yog qhov zoo tiag tiag. Peb tau sib cais MTP connectors tom qab peb xyoos ntawm kev siv, tej zaum 500+ mating cycles, pins qhia yuav luag tsis pom hnav. Ib lub tsev MPO los ntawm tib lub sijhawm, cov lus qhia tus pin yog pom tau tias flattened.

Tab sis ncaj ncees, qhov sib txawv no feem ntau tseem ceeb rausiab -frequency mating scenarios. Yog hais tias nws yog lub pob tw cable uas tau nruab thiab tsis txav mus rau peb xyoos, tus pin hnav tsis muaj teeb meem ntau.

Insertion Loss Testing

Qhov no yog qhov teeb meem tseem ceeb. US Conec official spec (2024-Q3 catalog, Table 3):

MTP Cov Neeg Tseem Ceeb: Tsawg dua lossis sib npaug rau 0.25dB max (97% kev ntseeg siab), feem ntau 0.10-0.15dB
MTP Txuj: Tsawg dua lossis sib npaug rau 0.50dB max, raug 0.25-0.35dB

Hauv tsev siab- kawg MPO peb tau sim (yuav tsis muaj npe), batch-rau-batch variation loj dua:

Zoo batch: 0.25-0.40dB
Tsis zoo batch: 0.45-0.65dB
Qee zaus outliers tshaj 0.7dB

Qhov ntawd yog qhov teeb meem. Nws tsis yog tias MPO hauv tsev yog txhua yam phem. Nws yog tussib xws. Cov batch no yuav zoo, tom ntej batch muaj teeb meem. Yog tias koj yog ib tus neeg siv khoom loj heev yuav ntau txhiab cables ib zaug, qhov sib txawv ntawd yuav ua rau koj pab pawg neeg vwm.

Tus nqi sib txawv yog dab tsi

Ntawm no yog peb cov ntaub ntawv sau tseg tsis ntev los no. FOB Shenzhen, 500+ txiav tawm, 30-hnub nqe lus:

Ua ntej- txiav lub cev cable (OM4, 15m, 24F MTP-rau-MTP)

Qhov chaw	Chav tsev Nqe	Sau ntawv
Hauv MPO (peb kab)	$78-95	2 lub lis piam ua ntej, IL daim ntawv qhia suav nrog
Hauv tsev "Elite-qib" MPO	$125-150	Yuav tsum tau cherry - xaiv batch, 3-4 lub lis piam
US Conec MTP Txuj	$165-190	Los ntawm kev faib khoom, 4-6 lub lis piam
US Conec MTP Cov Neeg Tseem Ceeb	$220-280	Xav tau PO ua ntej, feem ntau backordered

Tus nqi ntau yog nyob ntawm qhov ntev, suav fiber ntau, txawm tias koj xav tau cov ntaub ntawv kuaj fiber ntau. Cov lej saum toj no yog ballpark rau 15m / 24F.

Sab saud: Qee cov khoom hauv online muab cov nqi txuas txuas ntxiv ($ 1.5 vs $ 6 vs $ 15 yam khoom). Qhov ntawd yog rau xoob connectors koj yuav tsum tau txiav koj tus kheej. Tshwj tsis yog tias koj yog lub tsev cable sib dhos, tus lej ntawd tsis muaj nuj nqis rau koj. Kev yuav khoom ua ntej- cov cables uas tau txiav tawm yog txoj hauv kev ib txwm muaj. Peb cov quotes yog ib txwm ua tiav, kuaj cov rooj sib txoos.

Thaum twg Koj Tiag Xav Tau MTP Cov Neeg Tseem Ceeb

Tom qab tag nrho, qhov kev xaiv logic tsis yog qhov nyuaj. Nov yog ib qho kev sim yooj yim:

Xam koj cov peev nyiaj txuas.

Siv 400G-SR8. IEEE 802.3cm qhia meej channel tso nyiaj poob ntawm 1.9dB (100m OM4). Qhov 1.9dB yuav tsum npog:

Fiber attenuation (OM4 @ 850nm yog hais txog 3.5dB / km, yog li 15m yog 0.05dB, negligible)
Connector poob (qhov no yog qhov loj)
Tej splice poob
Aging margin

Hais tias koj muaj 4 connector mating ntsiab lus (transceiver rau thaj vaj huam sib luag, thaj vaj huam sib luag rau lub cev, lub cev rau thaj vaj huam sib luag, thaj vaj huam sib luag rau transceiver). Yog hais tias txhua qhov taw tes yog 0.5dB (generic MPO cov ntaub ntawv phem tshaj), connectors ib leeg noj 2.0dB. Tshaj nyiaj txiag.

Hloov mus rau MTP Cov Neeg Tseem Ceeb, 0.15dB raug × 4=0.6dB. Tawm 1.3dB npoo. Yooj yim.

Yog li400G thiab siab dua, lossis architectures nrog ntau lub hops, Cov Neeg tseem ceeb yog qhov yuav tsum tau ua. Tsis yog vim kuv xav muag koj cov khoom kim. Physics.

100G-SR4 pob nyiaj kuj tseem yog 1.9dB, tab sis feem ntau tsawg dua hops (ob lossis peb), yog li tus qauv MTP lossis txawm tias MPO zoo hauv tsev tuaj yeem ua haujlwm. Peb muaj cov neeg siv khoom khiav 100G ntawm tag nrho -hauv tsev-MPO, tau khiav ob xyoos yam tsis muaj teeb meem. Tab sis lawv cov architecture yog yooj yim. ToR ncaj qha mus rau qaum, tsuas yog ob lub ntsiab lus txuas ntawm.

40G thiab qis dua, nyiaj txiag poob yog kev zam txim ntau dua. Txuag nyiaj, tsis muaj teeb meem.

Cov khoom lag luam: Peb tau nqis tes ua, Dab tsi cov neeg siv khoom tau nqis los

Qhov no tej zaum yuav muaj txiaj ntsig zoo rau koj.

Npuag 1: Polarity Reversed

Cov xov xwm qub tab sis tib neeg tseem raug hlawv.

TIA-568.3-E txhais hom A/B/C polarity method. Yooj yim version: Hom B yog qhov yooj yim tshaj plaws. Lub cev muaj qhov tseem ceeb- mus txog qhov tseem ceeb ntawm ob qho kawg, siv cov hlua khi zoo ib yam ntawm ob sab, txoj haujlwm fiber ntau pib tig.

Tab sis ntawm no yog qhov:Cisco's default config thiab Arista / Juniper's txawv. Ntau Cisco iav muaj MPO ports nrog Method A pinout. Yog tias koj lub cev yog Txoj Kev B, thaj qaum yog B, txuas rau Cisco cov cuab yeej yuav xav tau polarity -flipping adapters lossis Hom A thaj qaum tshwj xeeb.

Peb tau hlawv ib zaug. Cov neeg siv khoom qaum yog Arista, ib nrab ntawm nplooj yog Cisco Nexus. Peb xa txhua yam Txoj Kev B. Cisco sab yuav tsis tuaj. Tau taug qab nws mus rau polarity. Yuav tsum tau huab cua freight ib pawg ntawm A- mus rau -B hloov pauv thaj qaum los kho nws. Noj tag nrho cov npoo ntawm qhov kev txiav txim.

Tam sim no thaum peb txiav txim peb nug txog cov khoom muag khoom sib xyaw. Ib puag ncig nyuaj, peb pom zoo MTP PRO ( teb- hloov pauv tau), lossis tsuas yog npaj ob hom kab hlua sib cais.

Npuag 2: Txiv neej/pojniam yuam kev

Kev sib txuas MPO / MTP xav tau ib qho kawg nrog cov lus qhia pins (Txiv neej) thiab ib qho tsis muaj (poj niam). Ob tug poj niam connectors mated ua ke yuav tsis ua hauj lwm. Cov pins tsis muaj qhov twg mus.

Cov qauv kev coj ua: lub cev siv cov txiv neej txuas, cov hlua khi siv poj niam. Tab sis qee yam khoom siv (xws li qee yam Mellanox / NVIDIA InfiniBand phaib) muaj poj niam transceiver tawb. Koj lub patch qaum xav tau Txiv neej kawg los ntsaws rau hauv.

Pom zoo: paub meej tias poj niam txiv neej configuration ntawm koj transceivers thiab thaj panels ua ntej xaj. Yog tias koj tsis paub meej, xa peb cov qauv khoom siv. Peb mam li saib.

Caw 3: Grey Market Khoom

US Conec cov khoom qub muaj kev tiv thaiv -cov ntawv cuav ntawm kev ntim khoom thiab laser -etched batch codes ntawm cov khoom sib txuas. Muaj qhov pom tseeb cuav ntawm kev ua lag luam, tus nqi tsis txaus ntseeg, tsis muaj kev lees paub.

Yuav qhia li cas:

"Original MTP" luv nqi 40% + hauv qab kev ua lag luam yog yuav luag tsis tseeb
Nug tus neeg muag khoom rau US Conec daim ntawv tso cai los yog daim ntawv yuav khoom
Xyuas cov ntim thiab etching thaum koj tau txais cov khoom

Peb tsis kov lub lag luam grey, tab sis peb tau pom cov neeg siv khoom yuav los ntawm lwm txoj kev, raug hlawv, tuaj rau peb pab. Qhib cov connectors, ferrule polish zoo yog kom meej meej, qhia pins tsis yog cov khoom qub. Tsis tsim nyog txuag nyiaj ntawd.

Caw 4: Fake Test Reports

Ua ntej- cov cables uas tau txiav tawm yuav tsum tuaj nrog IL/RL cov ntaub ntawv xeem. Tab sis cov ntawv ceeb toom tuaj yeem ua photoshopped.

Yam yuav tsum tau kuaj:

Daim ntawv tshaj tawm muaj tus lej xov tooj tshwj xeeb cuam tshuam rau lub cable tiag
Cov cuab yeej xeem dab tsi (cov ntawv ceeb toom raug cai Fluke/EXFO/Viavi qauv tooj)
Yog cov kev xeem tau teev tseg (wavelength, siv txoj kev)
Puas yog cov ntaub ntawv "zoo meej heev"? Txhua channel ntawm raws nraim 0.15dB, tej zaum fabricated

Peb cov ntawv ceeb toom los ntawm EXFO, txhua lub cable txhua fiber ntau muaj cov ntaub ntawv tus kheej. Cov channel zoo yuav pom 0.08dB, lwm tus 0.18dB. Qhov ntawd yog qhov kev sim tiag tiag zoo li. Txhua tus lej zoo ib yam txhais tau hais tias txoj kev xeem tsis raug lossis cov ntaub ntawv raug tsim.

Cleaning Isn't As Simple As You Think

Kev ntxuav tsis yog yooj yim li koj xav

Tej zaum koj tau hnov cov xwm txheej tias 80% ntawm kev ua tsis tiav los ntawm cov khoom siv qias neeg. NTT-AT's OPTIPOP cov ntaub ntawv cov khoom lag luam hais txog nws, Fluke luam tawm cov ntawv dawb zoo sib xws (tsis tuaj yeem nrhiav qhov tseeb tam sim no, xav tias nws nyob ib puag ncig 2018-2019).

Txawm hais tias nws yog 80% lossis 70% lossis txawm li cas los xij, kev sib kis yog tus lej ib qhov teeb meem tsis muaj teeb meem. Tshwj xeeb tshaj yog nrog MPO / MTP qhov twg ib qho ferrule muaj 8/12/24 fibers. Ib qho particle cuam tshuam rau tag nrho array.

Qee cov ntsiab lus siv tau:

1. "Saib kom huv" tsis txhais hais tias huv

1μm qhov tsis pom ntawm qhov muag tuaj yeem ua rau muaj teeb meem. Tshawb xyuas nrog lub tshuab ntsuas ntsuas ua ntej txhua qhov sib tov . 200x yam tsawg kawg nkaus, 400x zoo dua. Peb siv EXFO FIP-400B nrog MPO cov lus qhia tshwj xeeb raws li tus qauv.

2. Cov ntaub ntawv tu cev muaj lub neej ntev

Ntau tus neeg tsis paub qhov no. Daim kab xev cassette khaws cov khib nyiab los ntawm kev ntxuav yav dhau los. Siv nws ntau zaus thiab koj tab tom ntxiv kev sib kis tsis txhob tshem tawm. Feem ntau swap nws tawm tom qab 400-500 clicks.

3. Qhuav ua ntej, ntub tu thaub qab

Cov xwm txheej zoo li qub, qhuav huv yog txaus. Cov tawv nqaij tawv (xws li cov roj ntiv tes), ntub dej nrog 99% + IPA, tom qab ntawdtam sim ntawdqhuav huv, cestam sim ntawdtshuaj xyuas. IPA evaporation tsim zoo li qub uas nyiam cov khoom hauv huab cua. Yog tias koj muaj ionizer, tshuab nws ua ntej capping.

4. Tsis txhob hnov qab coj tus pin qhov

Lub ntsej muag Ferrule tej zaum yuav huv si, tus pin qhov tseem yuav muaj cov khib nyiab. Muaj ib tug tshwj xeeb pin qhov txhuam, zoo li ib tug me me xeem tube txhuam. Yog tias koj tseem muaj teeb meem kev sib raug zoo, kos rau ntawd.

5. Cov kaus mom plua plav tsis zoo tag nrho

Cov yas hauv lub kaus mom plua plav tuaj yeem tshem tawm - roj, thiab lub sijhawm ntev - capping yuav tso cov khoom paug. Tshawb xyuas hauv lub hau ua ntej txhim kho.
