MPO/MTP Fiber Guide: Polarity, Poj Niam Txiv Neej & Base-8 Migration (2026)

Cia wb ua tiag ib pliag. Migrating koj cov ntaub ntawv chaw los ntawm 10G mus rau 40G los yog 100G tsis yog ib tug yooj yim bandwidth upgrade; nws tuaj yeem ua npau suav phem logistical yog tias koj tsis npaj. Koj pauv cov LC patch cords yooj yim rau tuabMPO / MTP fiber ntautrunks, thiab mam li nco dheev koj tab tom cuam tshuam nrog polarity maps uas zoo li cov lej sib npaug.

Yog tias koj ntsaws tus qauv LC cable tsis raug, koj tsuas yog tig nws. Tab sis yog tias koj ntsaws ib qhoMPO lub cev cabletsis ncaj ncees lawm? Tej zaum koj yuav tau saib ntawm qhov txuas tsaus nti, lub teeb liab tsis zoo, lossis - qhov xwm txheej phem tshaj - lub lens crushed ntawm $ 500 transceiver. Peb pom nws tshwm sim txhua lub sijhawm hauv thaj chaw. Cia peb ua kom nws tsis tshwm sim rau koj qhov project.

MPO vs. MTP Fiber: Puas yog "Premium" Hom Tsim Nyog?

Nug tsib tus neeg muag khoom sib txawv, thiab koj yuav tau txais tsib cov lus teb sib txawv. Nov yog qhov tseeb tiag:MTP®yog technically lub npe hom rau MPO connector, muaj los ntawm US Conec. Tab sis lawv puas zoo ib yam? Tsis raws nraim.

Xav txog tus qauv MPO raws li lub khw muag khoom lag luam, thiabMTP fiber ntauraws li lub siab -end engineered version. Qhov txawv tiag tiag nyob rau hauv "floating ferrule." Hauv MPO generic, cov vaj tsev yas feem ntau clamps nyuaj dhau. Yog hais tias lub cable tau rub los yog twisted nyob rau hauv ib tug neeg coob rack, cov lus qhia fiber ntau poob kev sib cuag ntawm lub cev.

CovUS Conec MTPconnector ntab. Nws txav. Nws nyob twj ywm txuas txawm tias thaum koj tus kws kho tsheb cabling me ntsis ntxhib nrog lub installation.

Kuv Cov Lus Qhia Tshwj Xeeb:Rau koj tus txha nraub qaum (tus txha nraub qaum ntawm koj lub network), them nyiaj ntxiv rau MTP qhov tseeb. Rau qhov tsis yog - lub rooj sib tw tseem ceeb? Generic MPO tej zaum kuj zoo.

"Gender" Trap: Txiv neej (Pinned) vs. Poj niam (Unpinned)

Qhov no yog qhov yuam kev kim tshaj plaws uas pib ua thaum xajMPO / MTP fiber ntau. Tsis zoo li tus qauv LC connectors, MPO connectors muaj poj niam txiv neej, thiab lawv tsis ua si zoo yog tias koj sib tov.

To taub qhov txawv

Txiv neej (Pinned):Zoo li lub ntsaws nrog ob daim ntawv qhia hlau spikes protruding ntawm lub ntsej muag.

Poj niam (Unpinned):Nws muaj ob lub qhov qhia.

Txoj Cai Golden

Nov yog txoj cai uas koj yuav tsum tau ua daim kab xev rau ntawm koj cov phab ntsa warehouse:Optical Transceivers (zoo li QSFP28) yuav luag txhua tus Txiv neej.Yog li, yog koj sim yuam aTxiv neej MPO cablehauv aTxiv neej transceiver... crunch. Koj tsuas yog rhuav tshem cov pins sib dhos thiab tej zaum yuav tawg lub lens optic. Nco ntsoov xyuas koj BOM. Yog tias nws ntsaws rau hauv lub transceiver, koj xav tauPoj niamkab. Lub sijhawm.

Cracking the Polarity Code: Method A, Method B, lossis Method C?

"Method A, Method B, Method C." Nws zoo li ntau yam -cov lus nug xaiv uas koj tsis tau kawm. Cov neeg feem coob overcomplicate qhov no. Hauv lub ntiaj teb niaj hnub 40G / 100G data center, koj tsuas yog yuav tsum tau saib xyuasTxoj kev B.

Vim li cas? VimTxoj kev Byog tus qauv "Key-Up to Key-Up" standard. Nws flips lub teeb liab lawm (Pin 1 mus rau Pin 12). Nws yog qhov feem ntau Cisco, Arista, thiab Juniper iav xav tau.

Cov kws tshaj lij ceeb toom:Tsis txhob sib tov Method A cables nrog Method B cables hauv tib qhov txuas. Qhov ntawd yog qhov koj tau txais "dab" cov teeb meem kev sib txuas uas siv sij hawm los daws teeb meem. Xaiv tus qauv (mus nrog B) thiab ua raws li kev ntseeg.

Base-8 vs. Base-12: Yav tom ntej-Proofing rau 400G

Tau ntau xyoo, peb txhua tus khiav 12-fiber cables (Base-12). Nws ua rau kev txiav txim siab thaum lub sijhawm. Tab sis saib kojQSFP28 (100G SR4)transceivers. Lawv tsuas yog siv 8 fibers (4 rau kev xa, 4 rau kev txais).

Yog tias koj ntsaws ib txwm 12-fiberMPO lub cev cablehauv qhov module, yuav ua li cas rau nruab nrab 4 fibers?Tsis muaj dab tsi.Lawv mus tsaus ntuj. Koj tau them nyiaj rau iav (thiab cov khoom siv tsho) uas koj yuav tsis siv.

Tias yog vim li cas cov neeg tswj xyuas cov ntaub ntawv ntse tau hloov mus rauBase-8 MPO / MTP fiber ntauarchitectures. Nws yog 100% ua tau zoo rau SR4 modules, huv si los tswj, thiab zoo kawg nkaus positioned rau kev tsiv teb tsaws mus rau 400G SR8.

Yog vim li cas "Low Loss" Tsis yog Marketing Hype xwb

Kuv paub, "Low Loss" suab zoo li kev muag khoom nce -muag. Tab sis nyob rau hauv 100G tes hauj lwm, kev ua lej yog siab phem. Koj muaj peev nyiaj poob tag nrho me me-tej zaum 1.9dB tag nrho rau tag nrho qhov txuas.

Cia peb ua lej ntawm tus qauvMPO connector, uas noj txog li 0.7dB rau ib tug phooj ywg.

Qhov Txuas: Transceiver -> Cassette -> Patch Panel ->Transceiver.

Lej:4 mates x 0.7 dB =2.8dB ua.

Pom qhov teeb meem? Koj twb ua tsis tau tejyam nyiaj txiag ua ntej koj txawm tig mus.Cov neeg tseem ceeb (tsawg poob) MPOconnectors txiav qhov insertion poob mus rau0.35dB. Nws tsis yog khoom kim heev; rau kev khiav mus ntev lossis nyuaj topologies, nws yog tib txoj kev uas lub teeb tau mus rau lwm qhov kawg.

Xaus: Cia peb tsim qhov txuas uas ua haujlwm

Tsis txhob cia cov tsiaj ntawv kua zaub ntawm MPO / MTP / ABC hem koj. Nws tsuas yog kav dej rau lub teeb. Qhov tseem ceeb yog qhov sib xws - tau txais poj niam los txiv neej, polarity, thiab nyiaj poob qis ua ntej koj xaj thawj spool.

Tseem tsis paub meej tias koj xav tau Hom B lossis Hom A?Tsis txhob twv. Xa peb daim duab kos ntawm koj lub network topology. Tiag tiag, tsuas yog kos rau ntawm daim ntaub so ntswg thiab xa email rau peb. Peb pab neeg ua haujlwm engineering yuav tshuaj xyuas koj qhov layout thiab qhia qhov tseebMPO / MTP fiber ntauconfiguration koj xav tau, yog li koj tsis tas yuav mob taub hau ntawm kev xa rov qab.
