MPO/MTP Fiber: Qhov Kev Sib Tham Tiag Koj Yuav Tsum Tau Ua Ua Ntej Koj Cov Ntaub Ntawv Ntxiv Tom Ntej Tsim

Lub Kaum Ib Hlis tas los, kuv tau txais xov tooj los ntawm ib tus neeg siv khoom hauv Phoenix. Lawv tsuas yog qhwv 100G txha nraub qaum- nplooj tsim tawm - rau lub hlis ntawm kev npaj, kev tswj hwm kab zoo nkauj, xim -coding txhua yam. Ib nrab ntawm uplinks yuav tsis sib tham.

Tig tawm ib tug neeg tuav lub thawv ntawm Hom B pob tw rau hom A tsim. Cov thawv ntsia zoo ib yam. Cov lej sib txawv ntawm ib tus lej.

Plaub teev ntawm kev daws teeb meem. A 6 AM ya davhlau rau lawv cov thawj coj engineer. Kev puas tsuaj zaum kawg: $ 14,200 hauv kev ua haujlwm kub ntxhov, ntxiv rau $ 1,847 rau qhov kawg - daim pib dav hlau feeb. Kuv tseem muaj daim ntawv them nqi screenshot nyob qhov twg.

Yog vim li cas kuv thiaj sau qhov no. MPO / MTP fiber ntau tsis yog foob pob hluav taws kev tshawb fawb, tab sis cov ntsiab lus yuav ua rau koj puas tsuaj yog tias koj tsis saib xyuas. Thiab lub txim nplua nrog koj qhov chaw nres nkoj suav - mess up ib LC thaj, koj poob ib qhov txuas. Ntxo ib lub pob MTP, koj poob kaum ob.

MPO vs MTP: Cia peb tua qhov tsis meej pem

Kuv tau txais cov lus nug no tas li. "MTP puas yog MPO kim?"

Hom ntawm. Tab sis qhov ntawd zoo li nug yog tias Lexus tsuas yog Toyota kim xwb. Technically yog, xyaum tsis muaj.

MPO yog tus qauv txuas. IEC 61754-7, TIA-604-5 - Cov ntawv sau ib txwm muaj Txhua lub Hoobkas nrog lub ferrule pwm tuaj yeem thwj tawm MPO connectors.

MTP yog US Conec lub npe. Lawv tau tsim ntau -fiber push- ntawm hom, tom qab ntawd siv sijhawm ntau xyoo los kho nws. Tib cov hneev taw, nruj dua, cov ntaub ntawv zoo dua.

Nov yog qhov feem ntau cov duab sib piv tsis nco: tsis nco qab cov yas- piv- hlau clamp debate. Qhov ntawd yog kev cuam tshuam.

Lub elliptical qhia tus pin yog tag nrho cov ballgame.

Standard MPO siv puag ncig qhia pins. Thaum koj mate ob connectors, round pins tuaj yeem wobble me ntsis hauv lub tes tsho sib dhos -tej zaum ib micron ntawm no, micron nyob ntawd. Tsis zoo li ntau. Tab sis ua li ntawd 200 zaug, thiab cov qauv hnav tsis sib xws. Sab nrauv fiber ntau pib drifting. Koj qhov kev nkag mus poob creeps.

MTP tus pins elliptical? Lawv tus kheej -center. Txhua lub sijhawm. Koj tuaj yeem hnov ​​​​qhov txawv thaum koj ntsaws rau hauv -qhov no yog qhov tseeb nias thaum lub rooj zaum tus pin, piv rau qhov tsis meej pem uas koj tau txais nrog MPO pheej yig.

Peb tau ua qhov kev sim tsim txom xyoo tas los: 437 mating cycles ntawm rau qhov sib txawv ntawm cov qauv sib txuas. Los ntawm lub voj voog 300, ob ntawm MPOs generic tau qhia 0.15 dB degradation ntawm txoj haujlwm 1 thiab 12. Cov MTPs? Txoj kab ncaj nraim mus txog lub voj voog 400.

Qhov ntawd 0.15 dB tsis suab txaus ntshai kom txog rau thaum koj tab tom tso peb cov ntsiab lus mating hauv 400G txuas nrog xoom npoo kom seem.

Dab tsi hauv Cov Khoom no

Cov lus qhia ceev ntawm lub cev, vim tias kev nkag siab lub siab pab thaum cov khoom tawg.

Lub Ferrule

Daim duab me me ceramic cib nrog 12 qhov drilled hauv txoj haujlwm raug txog li 1 micron. Tib neeg plaub hau yog 70 microns dav. Peb tab tom tham 1/70th ntawm plaub hau.

Nyob rau hauv MTP connectors, lub ferrule ntab ntawm springs. Vim li cas? Vim hais tias thaum koj jam ob connectors ua ke, lawv yeej tsis zoo tag nrho. Lub ntab tso cai rau lub ferrule micro- kho kom lub siab sib tiv tauj sib npaug es tsis txhob sib tsoo ib lub kaum rau hauv oblivion.

Lub tshuab caij nplooj ntoos hlav ntawd kuj yog vim li cas koj yuav tsum tsis txhob tuag - tuav MTP cov khoom sib txuas thaum mating lawv. Kuv twb pom techs leeg lawv ua ke zoo li lawv tab tom zawm cov txiv ntoo. Tag nrho cov ntsiab lus ntawm ntab yog cia lub connector pom nws tus kheej sib dhos. Cia li thawb kom txog thaum nws nyem. Ua tiav.

Phau Ntawv Qhia Pins

Twb ranted txog tus tsim elliptical. Cov pins lawv tus kheej yog cov hlau tawv tawv-lawv muaj sia nyob ntau txhiab qhov ntxig yam tsis muaj nceb.

Txiv neej connectors muaj tus pins. Poj niam connectors muaj lub qhov. Suab meej, tab sis kuv tau saib tib neeg sim ua phooj ywg txiv neej-rau- txiv neej thaum 2 teev sawv ntxov hauv lub txee tsaus. Tsis ua hauj lwm. Nug kuv seb kuv paub li cas.

Lub Tsev

Standard MTP vaj tse yog ib qho - thooj- polarity thiab poj niam txiv neej yog teem rau ntawm lub Hoobkas. Koj xaj yuam kev, koj tab tom xa rov qab cables lossis yuav cov vaj huam sib luag adapter.

Nov yog qee yam uas cov ntaub ntawv yuav tsis qhia rau koj: nyob rau hauv tsis yog - huab cua- tswj ntug qhov chaw lossis ib puag ncig kev lag luam, pheej yig MPO yas vaj tsev tau nkig tom qab ob peb xyoos. Hauv peb lub chaw soj ntsuam kev ntxhov siab, peb tau muab piv rau MTP cov vaj tsev tiag tiag tiv thaiv cov kev sib tw uas muaj nyob rau hauv huab cua kub. Ntau lub tuam txhab txiav cov nqi los ntawm kev sib xyaw cov khoom siv ntau dhau rau hauv lawv cov pwm hauv tsev- qhov no ua rau cov saw hlau molecular degradation uas tsis pom ntawm qhov muag liab qab. Tab sis tom qab kev ntsuam xyuas thermal cycling (-40℃rau +75} degree), latch qaug zog poob los ntawm 40%. Peb tau txais "disintegrated" connectors rov qab los ntawm cov neeg siv khoom, thiab kev tsom xam teardown tsis tu ncua qhia cov khoom siv classic embrittlement. Yog vim li cas peb hais kom siv tsuas yog high-spec virgin polyetherimide (PEI) resin. Nws raug nqi ntau dua ntawm daim ntawv, tab sis nws ua kom koj cov khoom sib txuas tseem ua phooj ywg nrog tib lub ntsej muag nyem tom qab kaum xyoo hauv cov ntaub ntawv chaw.

MTP PRO kho qhov teeb meem configurability (ntxiv rau qhov ntawd tom qab), tab sis tam sim no, tsuas yog paub: triple - xyuas koj cov specs ua ntej xaj. Cov txheej txheem RMA rau $ 400 lub cev cable siv sijhawm peb lub lis piam.

Polarity. Them mloog ntawm no.

Kuv yuav siv sij hawm ntau dhau ntawm nqe lus no vim tias qhov yuam kev polarity account rau tej zaum 60% ntawm MPO kev daws teeb meem hu kuv tau ua. Nws dhuav. Nws yog tedious. Thiab nws yuav rhuav tshem koj cov hmo Thursday yog tias koj tsis quav ntsej nws.

Duplex fiber yog yooj yim. TX to Rx, Rx to Tx. Ib tug me nyuam me tuaj yeem xav txog nws.

Kaum ob fibers nyob rau hauv ib tug connector? Txhua txoj haujlwm tseem ceeb. Thiab muaj peb -THREE- txoj kev sib txawv ntawm cov tuam txhab xaim cov kab no.

Hom A

Kuaj rau ntawm ib kawg, nyem rau ntawm lwm qhov. Lub cable sab hauv tsom iav fiber ntau array. Txoj hauj lwm 1 mus rau txoj hauj lwm 1, tab sis lub cev flip txhais tau hais tias cov khub kab mus kom raug rau duplex breakouts.

Hom B

Ob qhov xaus tseem ceeb. Cov kab sib txuas sib txuas ua ke: 1↔2, 3↔4, 5↔6, thiab lwm yam. Feem ntau rau SR4 transceivers.

Hom C

Kuv tus kheej ntxub hom C. Tus qauv suav nrog nws, tseeb. Tab sis hauv kev xyaum? Nws yog ib tug ntxiab.

Hom C ua ib khub tig rau sab saum toj ntawm Hom A flip. Tib lub sij hawm kuv tau pom nws siv kom raug yog nyob rau hauv cov keeb kwm tshwj xeeb Cisco config, thiab txawm tias tom qab ntawd, cov thev naus laus zis uas tau teeb tsa nws tsis muaj ntaub ntawv. Peb tau siv ob hnub thim rov qab- engineering daim ntawv qhia polarity.

Kuv cov lus qhia: tshwj tsis yog tias koj sib piv hom C infrastructure uas twb muaj lawm, ua piv txwv tias nws tsis muaj. Koj yuav pw zoo dua.

Vim li cas qhov no tseem ceeb hauv lub neej tiag

Ntawm no yog ib qho kev txha nqaj qaum-kab nplooj:

Ntiv tes hloov → Hom B pob tw → MTP thaj vaj huam sib luag → Hom A thaj → Nplooj hloov

Txhua yam ua haujlwm. Tam sim no xav txog ib tug neeg -tej zaum tus neeg cog lus, tej zaum hmo ntuj nrawm heev-hloov tech- hloov pauv hom B lub cev rau hom A. Cov thawv zoo ib yam. Cov ntawv me me.

Yuav ua li cas? Kev sib txuas ib nrab. Fibers 1-2 ua haujlwm. Fibers 3-4 tsis. Fibers 5-6 ua haujlwm. Thiab li ntawd.

Cov tsos mob zoo nkaus li zoo li qhov tsis zoo transceiver. Los yog qias neeg connector. Los yog fiber ntau so. Koj yuav nkim sij hawm caum cov dab ua ntej ib tug neeg thaum kawg tawg tawm lub polarity mapper thiab pom qhov teeb meem tiag tiag.

Raws li cov chaw tsim khoom, qhov txaus ntshai tshaj plaws tsis yog cov txheej txheem txuas txuas txuas ntxiv -nws yog "kev ua yuam kev zais cia." Hauv peb lub xyoo caum- ntxiv rau ntawm kev tsim khoom, peb tau pom tias muaj dab tsi tshwm sim thaum cov txheej txheem sib dhos tsis muaj kev tswj xyuas kom raug. Hom kev ua tsis tiav feem ntau? Polarity yuam kev los ntawm fiber ribbon rotation thaum txiav. Yog tias tsis muaj kev txheeb xyuas qhov tseeb, cov neeg ua haujlwm qaug zog tuaj yeem tig tsis tau rov qab 180 degrees - qhov yuam kev uas tsis pom ntawm qhov muag liab qab tab sis ua rau muaj kev puas tsuaj rau qhov txuas. Kev lag luam tsis ua hauj lwm soj ntsuam cov ntaub ntawv qhia tias qhov no suav nrog kwv yees li 1% ntawm cov cables los ntawm cov chaw yam tsis muaj kev ntsuas ntsuas. Ntawm peb cov kab ntau lawm, peb tswj hwm qhov kev ntsuas polarity tag nrho{10}}txhua lub xov tooj yuav tsim cov cim polarity ntiv tes ua ntej nws xa khoom. Kev tswj hwm polarity yuav tsum tsis yog nyob ntawm kev txhim kho hmoov zoo; nws yuav tsum tau muab xauv rau ntawm lub Hoobkas los ntawm lub cev foolproofing thiab automated soj ntsuam.

Tom qab npau suav phem ntawd, peb tau ua txoj cai nyuaj: ntawm txhua qhov kev xa tawm loj, peb random rub - sim 5% ntawm cov cables ua ntej lawv mus rau hauv lub tais. Txheeb xyuas qhov tseeb fiber ntau daim ntawv qhia, tsis yog daim ntawv nplaum. Tsis txhob tso siab rau daim ntawv lo.

Qhov Kho

Cov ntaub ntawv. Txhua yam.

Ua ntej koj khiav ib lub cable, tsim ib daim ntawv qhia polarity. Daim ntawv nthuav qhia, Visio daim duab, daim duab kos duab daim duab -Kuv tsis quav ntsej. Cia li sau cia:

Hom kab twg mus qhov twg

Qhov kev taw qhia qhov tseem ceeb ntawm txhua qhov kawg

Yuav ua li cas fiber ntau -rau-fiber mapping yog

Sau ob qhov kawg ntawm txhua lub cable nrog rau hom polarity. Tsis yog tus naj npawb ib feem - qhov tseeb polarity. Kuv siv daim kab xev xim: xiav rau A, daj rau B. Tsawg-tech, tab sis nws ua haujlwm.

Ib tus neeg siv khoom kuv ua haujlwm nrog luam tawm QR cov lej uas txuas rau lawv cov ntaub ntawv khaws cia. Overkill? Tej zaum. Tab sis lawv tsis tau muaj qhov xwm txheej polarity hauv peb xyoos.

Nco tseg: Qhov ob - ntu txoj kev tswj xyuas qhov tseeb polarity rau 4 × 25G breakout. Hloov ob lub cable yam tsis suav rov qab, thiab koj tab tom teeb meem thaum ib tag hmo.

Loss Budget Math

Txhua qhov txuas kho qhov muag muaj lub zog siv nyiaj txiag. Transmitter tso tawm X dBm. Tus txais yuav tsum tau tsawg kawg yog Y dBm. Qhov txawv yog koj cov peev nyiaj poob -uas yog qhov koj siv ntawm fiber ntau attenuation, connector poob, thiab splices.

Ntawm 10G, cov peev nyiaj poob tau siab dav. Koj tuaj yeem siv cov khib nyiab txuas thiab tseem muaj cov npoo.

Thaum 100G, lej tau nruj dua.

Ntawm 400G, koj suav feem kaum ntawm dB zoo li tus neeg suav nyiaj npib.

100GBASE-SR4 Piv txwv

IEEE muab 1.9 dB tag nrho cov channel poob rau 100G SR4 tshaj OM4 ntawm 100 meters.

Cia peb tsim qhov sib txuas tiag tiag:

100m OM4: 3.5 dB/km × 0.1 km=0.35 dB

Ob lub MTP matings (hloov → vaj huam sib luag, vaj huam sib luag → thaj)

Yog tias koj siv generic MPO ntawm 0.75 dB txhua:

Qhov ntawd tsis yog margin. Qhov ntawd yog qhov yuam kev bar ntawm koj cov cuab yeej kuaj.

Ib plua plav ntawm ib kawg -lub ntsej muag, thiab koj siv nyiaj ntau dhau. Ib me ntsis ntev cable khiav, tshaj nyiaj txiag. Ib qho kev sib txuas uas tuaj ntawm hnub Friday yav tav su ua haujlwm ntawm lub Hoobkas, tshaj nyiaj txiag.

Tib qhov txuas nrog MTP Elite ntawm 0.35 dB txhua:

Tam sim no koj ua pa. Plua plav tshwm sim. Kub drifts. Fibers muaj hnub nyoog. Qhov ntawd 0.85 dB margin absorbs lub ntiaj teb tiag.

Txoj Kev Trip Analogy

Xav txog kev poob nyiaj xws li tsav tsheb hla- lub teb chaws nrog lub tank roj uas koj tuaj yeem rov qab tsis tau.

Generic MPO pib koj ntawm ib nrab ntawm lub tank. Kev mus ncig luv? Zoo. Tab sis sim ua kom nws los ntawm Phoenix mus rau Denver, thiab koj tawm hws txhua mais, coasting rau hauv qhov chaw nres tsheb roj ntawm cov pa taws.

MTP Elite pib koj tag nrho. Tib lub hom phiaj, tab sis tam sim no koj tuaj yeem taug kev, khiav AC, tsis txhob ntshai thaum koj ntaus kev tsim kho tsheb.

Lub hom phiaj (koj cov ntaub ntawv tus nqi) tsis hloov. Koj cov paj rau surprises ua.

MTP Elite vs Standard: Thaum Yuav Them Nyiaj

US Conec muag ob qib:

Txheem MTP:Max 0.50 dB ntxig poob. Feem ntau yog nyob ib ncig ntawm 0.35 dB.

MTP neeg tseem ceeb:Max 0.35 dB. Feem ntau yog 0.15-0.25 dB.

Cov neeg tseem ceeb raug nqi 15-30% ntau dua nyob ntawm cov suav fiber ntau thiab cov neeg muag khoom. Tsim nyog nws?

Nov yog qhov kuv xav txog nws.

Mus Elite thaum:

Koj cov lej poob qis dua 0.5 dB npoo tom qab txhua yam ntxiv lawm

Koj muaj peb lossis ntau tshaj mating ntsiab lus nyob rau hauv txoj kev

Koj tab tom ua 400G tam sim no, lossis yuav nyob hauv 3 xyoos

Cov kab hluav taws xob yog cov pob txha pob txha uas yuav nyob hauv cov phab ntsa rau kaum xyoo

Standard yog zoo thaum:

Txuas hauv qab 50m nrog tsuas yog 1-2 matings

Cov paj tau yooj yim ntawm 40G lossis 100G

Patch cords koj mam li hloov txhua txhua xyoo txawm li cas los xij -vim li cas them nqi rau cov khoom siv?

Cov peev nyiaj nruj tiag tiag thiab koj tau ua lej los ua pov thawj nws ua haujlwm

Kuv txoj cai dav dav: Cov neeg tseem ceeb rau pob tw, Txheem rau thaj ua rau thaj.

Ntawm no yog lub logic. Cov pob tw mus rau hauv qab nthab, hauv qab hauv pem teb, los ntawm cov phab ntsa. Lawv nyob ntawd tau 7-10 xyoo. Qhov ntawd yog koj lub hauv paus network-koj yeej tsis tuaj yeem pheej yig tawm ntawm kev poob qis rau cov txheej txheem koj yuav tsis kov rau ib xyoo caum.

Los ntawm kev tsim cov ntsiab lus tseeb, qhov sib txawv ntawm cov neeg tseem ceeb thiab cov qib Standard tsis yog 0.1 dB ntawm daim ntawv. Kev tsim cov neeg tseem ceeb- qib txuas txuas ntxiv yuav tsum tau txuas ntxiv super- polishing ntawm qhov kawg- ntsej muag thiab tsis lees paub cov ferrules nrog ciam teb geometry tsis zoo li apex offset. Kuv hauv qab - kab lus pom zoo rau cov neeg siv khoom: trunks yuav tsum yog Elite. Thaum cov kab txuas txuas tau muab faus rau hauv cov tais cable, lawv cov ntsiab lus mating yog tsau. Patch cords yog kua thiab tau hloov tas li. Yog tias koj lub cev ferrule geometry tsis zoo tag nrho, nws tsis muaj teeb meem zoo npaum li cas koj cov kab hluav taws xob zoo li cas - lub cev tiv thaiv lub cev yuav tsis sib npaug. Siv nyiaj rau cov khoom precision uas tsis txav mus los. Qhov ntawd yog tus nqi tswvyim uas ua rau muaj kev nkag siab zoo hauv kev tsim khoom.

thaj? Lawv yog cov khoom siv. Ops techs yank lawv, reroute lawv, nqis rau lawv, yuam kev yob lub rooj zaum hla lawv. Qhov nruab nrab lifespan tej zaum yog rau lub hlis mus rau ib xyoos ua ntej lawv tau txais kev sib pauv. Kev siv nyiaj ntau dua rau cov neeg tseem ceeb thaj ua rau thaj thaum khiav cov pob tw marginal rov qab -koj tab tom polishing lub qhov rooj thaum lub hauv paus tawg.

Ib qho kev zam: yog tias koj hla - txuas los ntawm kev sib ntsib - kuv chav hauv colo, mus Elite txhua qhov chaw. Koj tuaj yeem tswj tsis tau cov kab hluav taws xob zoo nyob rau sab nraud ntawm lub vaj huam sib luag ntawm tes.

MTP PRO: Kho teb ua haujlwm tiag tiag

Tsoos MTP xauv hauv polarity thiab poj niam txiv neej ntawm lub Hoobkas. Order yuam kev? Rov qab los, tos peb lub lis piam, piav qhia rau koj tus thawj tswj hwm qhov project vim li cas lub sijhawm poob.

MTP PRO cia koj hloov polarity (Hom A ↔ Hom B) thiab poj niam txiv neej (txiv neej ↔ poj niam) hauv thaj teb. Tsis muaj cov cuab yeej tshwj xeeb rau polarity- tsuas yog pop lub vaj tsev. Kev sib pauv poj niam txiv neej xav tau cov cuab yeej rho tawm tus pin, tab sis nws tseem yog txoj haujlwm 30 thib ob.

Tus nqi them yog 20-40% tshaj tus qauv MTP. Suab nrov.

Tab sis cia peb ua lej ntawm tus ntsia hlau-up:

Yog tias koj tab tom ua qhov kev xa tawm loj nrog qhov tsis meej meej txog qhov uas twb tau teeb tsa lawm, MTP PRO them rau nws tus kheej thawj zaug ib yam dab tsi tsis haum rau daim duab.

Rau qhov chaw nyob lossis thib peb -ib puag ncig tswj hwm, peb feem ntau pom zoo cov neeg siv khoom spec MTP PRO ncaj qha. Hauv cov xwm txheej "black box" qhov twg koj tsis tuaj yeem kwv yees qhov kawg ntawm qhov polarity lossis poj niam txiv neej, thaj chaw - hloov pauv tau ntawm PRO tsis yog yooj yim xwb - nws yog kev pov hwm. Peb tau pom cov neeg siv khoom kaw tag nrho kaum- txhiab- cov haujlwm fiber ntau rau ib lub lis piam vim tias ob qho tib si xaus los ua txiv neej. Raws li cov chaw tsim khoom, peb tsim PRO-series connectors rau tes teeb tsa txoj cai rov qab mus rau qhov chaw- tshem tawm cov kev pheej hmoo ntawm cov khoom lag luam uas tshwm sim los ntawm qhov tsis sib xws thaum ntxov{10}}.

Rau me me, zoo -cov ntaub ntawv tsim nyob qhov twg koj tswj txhua qhov sib txawv? Standard yog zoo.

MTP-16: Tsis Siv Neeg Fiber

Tsis pub leejtwg paub txog 12-fiber MTP: nws nkim ib feem peb ntawm koj cov fiber ntau rau 8-kab kev siv.

40G siv 4 kab (8 fibers). 100G siv 4 kab (8 fibers). 400G siv 8 kab (16 fibers). 800G siv 8 kab (16 fibers).

MTP-16 kho qhov no. Kaum rau fibers, yim duplex khub, xoom pov tseg.

Rau 400G-SR8 thiab 800G nthwv dej yav tom ntej, MTP-16 yog qhov tseem ceeb hauv keeb kwm. Yog tias koj tab tom tsim kho tshiab AI kev cob qhia infrastructure-cov GPU pawg uas xav tau 400G lossis 800G ntawm txhua qhov ntawm tus qauv ntawm MTP-16 tam sim no. Tus nqi delta yog negligible, thiab koj yuav tsis tau ripping tawm 12-fiber trunks nyob rau hauv ob xyoos.

Hnov los ntawm kev sib cuag hyperscaler lub hli tas los: lawv twb tau cog lus rau MTP-16 rau txhua qhov kev tsim kho tshiab. Kev txhim kho kev siv fiber ntau ib leeg ua rau kev hloov pauv ntawm cov cuab yeej.

Xaus-Kev Tshawb Fawb Lub ntsej muag: Qhov Kev Nyuaj Siab Uas Txuag Koj

Kuv yuav khaws qhov luv luv no vim nws yog lub ncauj lus uas tsis txaus ntseeg. Tab sis hla nws yog vim li cas tib neeg hlawv $ 2,000 transceivers.

MTP connectors muaj 12, 16, lossis 24 fibers hauv ib lub ferrule. Ib qho kab mob sib kis ntawm ib lub tank fiber ntau rau tag nrho cov khoom txuas. Qhov sib txawv ntawm cov kab mob sib kis nrog cov suav fiber ntau.

IEC 61300-3-35 txhais kom huv si. Nov yog cov ntsiab lus:

Lub cheeb tsam tseem ceeb ntawd -25 microns-yog qhov phem. Ib plua plav particle. Ib. Thiab koj qhov txuas 400G pib cuam tshuam CRC yuam kev.

Koj tsis tuaj yeem kuaj xyuas tus kheej 12+ fibers ib connector ib kawg rau txhua cable. Tau txais kev sojntsuam MTP automated ($ 4,000-8,000). Nws them rau nws tus kheej thawj zaug koj ntes cov kab mob ua ntej mating es tsis txhob tom qab hloov lub transceiver.

Cov txheej txheem ntxuav:

1. Tshawb xyuas ua ntej. Ib txwm.
2. Yog tias qias neeg: qhuav so. Ua haujlwm 80% ntawm lub sijhawm.
3. Tseem qias neeg: IPA ntub dej huv.
4. Re- tshuaj xyuas ua ntej sib yuav.
5. Ua tsis tiav tom qab ntub dej? Cov khoom txuas yuav raug puas tsuaj. Tsis txhob yuam nws.

Ib yam rookies tau yuam kev: lawv xav tias kev ntxuav ntub yog ib txwm zoo dua li qhuav. Ntawm MTP connectors, qhov ntawd yog kev puas tsuaj tos kom tshwm sim. IPA residue uas tsis tag nrho evaporate tsim cov nplaum micro- ntxiab hauv cov lus qhia tus pin qhov - thiab cov ntxiab no nyiam cov plua plav ntau dua li koj tau pib nrog.

Nyob rau hauv 400x lub Hoobkas microscope, peb feem ntau pom cov neeg tua neeg tsis pom nyob tom qab los ntawm "kev tu ntub dej": IPA residue films. Ntau tus neeg siv khoom siv lub tshuab ntxhua khaub ncaws los yog siab - cawv cawv, tab sis yog tias qhov sib tov sib xyaw tsis raug lossis evaporation tsis tiav, cov kua nplaum nplaum nplaum "locks" cov khoom zoo rau hauv MTP phau ntawv pin qhov. Tias yog vim li cas qee cov cables sim zoo tshiab tawm ntawm lub thawv tab sis qhia tias tsis muaj qhov poob tom qab tsuas yog ob peb lub voj voog mating. Peb lub khw hauv pem teb pom zoo: kev tu kom qhuav yog cuaj caum feem pua ​​​​ntawm cov neeg mob. Yog tias kev ntxhua khaub ncaws ntub yog qhov tsim nyog, siv cov khoom seem tshwj xeeb - cov kuab tshuaj ntxuav dawb ua raws li siab - siab nitrogen tshem tawm. Lub hom phiaj yog khaws cia "virgin integrity" ntawm qhov kawg ntawm fiber ntau- ntsej muag- tsis yog tshuaj degrading nws nrog kev kho mob ntau dhau.

Peb txoj cai: qhuav so ua ntej, ib txwm. Txuag cov ntaub ntub dej kom tsis txhob muaj kab mob tsis zoo- cov roj ntawm daim tawv nqaij los ntawm cov ntiv tes tech, cov nplaum nplaum, zoo li ntawd. Thiab yog tias koj ntub dej huv, ua raws li tam sim ntawd nrog ob daim ntawv so qhuav. Xav txog MTP zoo li precision optics: lub tshuab ziab khaub ncaws, kev nyab xeeb dua.

Ib qho kev nthuav dav uas feem ntau tau saib tsis pom: plua plav hau tsim teeb meem ntau dua li tib neeg paub. Cov kaus mom uas tuav nruj heev yuam cov kws kho mob kom yank ntawm lub khau raj thaum tshem tawm, uas ua rau muaj kev ntxhov siab rau lub rooj sib txoos ferrule. Thaum peb tsim peb lub kaus mom plua plav, peb tau tsim tshwj xeeb rau kev tuav nruj kom sib npaug tiv thaiv kev sib kis tau yooj yim ntawm kev tshem tawm - ruaj khov txaus kom nyob twj ywm thaum tuav, xoob txaus uas koj tsis sib tw nrog nws thaum 2 teev sawv ntxov hauv lub txee tsaus.Cov khoom me me li ntawd tsis nyob hauv ib daim ntawv teev cov ntaub ntawv.

Kev txiav txim siab Framework

Ntawm no yog daim ntawv cheat. Tab sis nyeem cov hnub qub- qhov ntawd yog qhov kev taw qhia tiag tiag.

Cov hnub qub:

⚠️ Nyob ze cov cuab yeej HVAC lossis compressors?Kev vibration loosens kev sib txuas thaum lub sijhawm. Mus MTP (hlau clamps) txawm tias qhov poob lej hais tias generic zoo.

⚠️ Lab ib puag ncig nrog reconfiguration tas li?MTP PRO, txawm tias polarity yog "paub." Cov phiaj xwm hloov. Txuag koj tus kheej mob taub hau.

⚠️ Txuas mus rau MPO trunks uas twb muaj lawm?Tsis txhob nkim nyiaj ntawm Elite thaj ua rau thaj - txhim kho cov pob tw ua ntej. Ib txoj hlua tsuas yog muaj zog raws li qhov tsis muaj zog txuas.

⚠️ Colo ntsib-kuv chav?Cov neeg tseem ceeb nyob txhua qhov chaw. Nov yog qhov hais txog qhov chaw nyob: koj tsis tuaj yeem tshawb xyuas dab tsi nyob rau sab nraud ntawm pawg demarcation. Koj tsis muaj lub tswv yim yog tias lawv siv cov jumpers zoo lossis qhov pheej yig tshaj plaws uas lawv qhov chaw yuav khoom tuaj yeem nrhiav tau. Qhov koj tuaj yeem tswj tau yog koj sab ntawm kev sib txuas. Mus rau cov neeg tseem ceeb ntawm koj qhov kawg tsim nyob rau hauv ib qho ntxiv 0.3 dB ntawm cov npoo- thiab nyob rau hauv "lub thawv dub" qhov chaw uas koj dig muag mus rau ib nrab ntawm qhov txuas, cov npoo feem ntau yog qhov txawv ntawm lub teeb ntsuab thiab lub tswb daj daj.

Rau MPO / MTP fiber trunks, cassettes, thiab breakout modules uas npog tag nrho cov no, koj yuav nrhiav tau cov ncauj lus kom ntxaws specs thiab Tshuag muaj nyob rau hauv lubEVOLUX catalog. Peb ntu fiber ntau optic connector suav nrog MTP-12, MTP-16, thiab PRO variants-tag nrho cov tsim nrog cov kev tswj zoo thiab kev soj ntsuam raws tu qauv tau tham thoob plaws hauv phau ntawv qhia no.

MPO / MTP fiber ntau tsis nyuaj thaum koj internalize peb yam:

Connector zoo scale nrog ceev.40G zam txim rau sloppiness. 400G tsis.

Polarity yuam kev zoo li txhua yam tshwj tsis yog polarity yuam kev.Cov ntaub ntawv ua ntej koj nruab.

Cov nyiaj poob qis tsawg dua li qhov koj xav.Ua lej. Yog tias nws nyob ze, hloov kho qhov txuas spec.

Thiab ib qho kev xav ntawm tus kheej: MTP Cov Neeg tseem ceeb ntawm cov pob txha caj qaum yog yuav luag ib txwm tsim nyog tus nqi. Tag nrho cov nqi sib txawv ntawm qhov chaw tsim cov ntaub ntawv yog qhov yuam kev sib npaug piv rau ib hmo ntawm kev daws teeb meem xwm txheej ceev.
