Tau mpo rau mpo cable txhawb 100G

Yog lawm. Luv teb ua tiav.

Tab sis yog tias koj tseem nyob ntawm no, muaj ntau ntau mus tom qab qhov yooj yim yog.

MPO to MPO Cable

Yog li 100G dhau MPO ua haujlwm los ntawm qee yam hu ua 100GBASE-SR4. SR4 feem txhais tau tias luv Reach, 4 kab. Koj tab tom khiav 25Gbps ntawm txhua txoj kab. Plaub kab kis tau, plaub kab tau txais. Qhov ntawd yog 8 fibers tag nrho ua haujlwm tiag tiag.

Ntawm no yog qhov uas nws tau txais me ntsis annoying txawm. Cov neeg feem coob tuav 12-fiber MPO cable vim tias qhov ntawd yog qhov tshwm sim hauv cov khoom siv. Koj xaus nrog 4 fibers tsuas yog zaum ntawd tsis ua dab tsi. Tsis yog qhov loj heev rau kev teeb tsa feem ntau tab sis nws cuam tshuam qee tus engineers kuv paub.

24-fiber MPO cables kuj muaj. Overkill rau theem pib 100G tab sis lawv ua rau kev nkag siab yog tias koj xav ua ntej rau 200G lossis 400G hauv txoj kev.

OM3 tau txais koj 70 meters.

OM4 thawb qhov ntawd mus rau 100 meters.

OM5 kuj hits 100 meters tab sis ntxiv SWDM wavelength kev txhawb nqa uas tseem ceeb rau qee qhov siab - qhov xwm txheej ceev. Cov neeg feem coob tsuas yog lo nrog OM4 ncaj ncees.

Tib hom - yog hom tsiaj sib txawv. PSM4 optics ntawm ib qho - hom MPO tuaj yeem ncav cuag 500 meters. Qee cov ntaub ntawv chaw khiav dej num xav tau qhov no. Lub tsev kawm ntawv qaum teb kev sib txuas ntawm cov tsev. yam ntawd. Tus nqi dhia nce considerably txawm.

MPO to MPO Cable

Tshooj lus no tuaj yeem yog nws tsab xov xwm. Cov teeb meem polarity tau ua rau lig - hmo ntuj kev daws teeb meem ntau dua li leej twg xav lees.

Ntaus -A: yuam sij mus rau qhov tseem ceeb. Ncaj los ntawm qhov pib. Hom -B: yuam sij rau ntawm ib qho kawg, nyem rau ntawm lwm qhov. Qhov no reverses cov haujlwm fiber ntau. Hom -C muaj qhov sib txuas sab hauv uas tshwm sim hauv lub cable nws tus kheej.

Tau qhov polarity tsis ncaj ncees lawm thiab qhov txuas xwb yuav tsis tuaj. Optics zoo. Cov cables kuaj zoo ntawm lawv tus kheej. Txhua yam zoo li ntawm daim ntawv. Tab sis qhov xa tawm fiber ntau ntawm ib kawg tsis yog tsoo qhov tau txais fiber ntau ntawm lwm qhov kawg. Classic yuam kev. Muaj tshwm sim txawm tias muaj kev paub txog techs thaum lawv rushing.

IEEE thiab TIA cov qauv muaj cov lus qhia tshwj xeeb rau qhov no. TIA-568 Txoj Kev A, B, thiab C sib raug rau cov kab no. Kev sib xyaw ua ke hauv tib lub channel yam tsis nkag siab cov ntsiab lus flip tsim teeb meem.

Txiv neejMPO connectorsmuaj cov ntawv qhia pins tawm. Cov poj niam muaj lub qhov. Yooj yim txaus.

Cov kab hauv lub cev feem ntau yog poj niam-poj niam. Patch cords zoo li txiv neej ntawm ib kawg, poj niam ntawm lwm tus. Thaum koj mate ib tug txiv neej rau ib tug poj niam, cov pins dlhos cov fibers precisely. Ob tug txiv neej ua ke yuav tsis ua hauj lwm. Ob tug poj niam xav tau txiv neej- txiv neej adapter lossis jumper nyob nruab nrab.

MPO to MPO Cable

Insertion poob yuav tsum nyob qis dua 0.35dB ib khub niam txiv rau 100G txuas. Qee tus neeg muag khoom spec nruj dua ntawm 0.25dB. IEEE txuas cov nyiaj poob haujlwm xav tias muaj qee qhov txiaj ntsig thiab yog tias koj cov khoom sib txuas dhau qhov kev txwv, koj pib noj rau hauv koj cov paj.

Rov qab poob yam tsawg kawg nkaus yog 20dB rau kev siv multimode.

Xaus-lub ntsej muag geometry yog qhov tseem ceeb ntawm no. Lub ferrule nto xav tau ib lub vojvoog ntawm curvature, fiber ntau protrusion, apex offset qhov tseem ceeb. Tag nrho cov no tau ntsuas thaum tsim khoom. Ib lub ntsej muag txuas uas tsis muaj paug pov tseg txhua yam. Ib plua plav plua plav tuaj yeem tawg txaus lub teeb kom ua rau me ntsis yuam kev.

IEC 61300-3-35 suav nrog cov txheej txheem tshuaj xyuas. Qib A, B, C, D aav ntawm cov tub ntxhais fiber ntau thiab cladding. Txhua qhov tsis xws luag hauv cheeb tsam tseem ceeb yog qhov ua tsis tiav.

MPO-12 tuav 100G zoo tam sim no.

MPO-24 tau dhau los ua ntau dua nrog 200G thiab 400G saws.

MPO-16 thiab MPO-32 muaj nyob rau cov ntawv thov tshwj xeeb. 32-fiber variant tshwj xeeb yog qhov tseem ceeb rau 400G-DR4 thiab 800G kev xa tawm qhov twg koj xav tau ntau txoj kab sib luag.

MPO to MPO Cable

Jacket ratings tseem ceeb nyob ntawm seb qhov twg cable khiav. LSZH rau cov cheeb tsam uas xav tau cov pa luam yeeb tsawg. Plenum- ntsuas rau huab cua tuav hauv North America. Riser- ntsuas rau ntsug khiav ntawm cov plag tsev.

Khoov vojvoog yog feem ntau 10x lub cable sab nraud txoj kab uas hla thaum lub sij hawm installation, so tej zaum 15x ib zaug ntsia thiab nyob rau hauv tsis muaj nro. Ua txhaum qhov no thiab koj pheej hmoo poob macrobend. Cov fibers lub cev khoov heev heev thiab lub teeb dim lub hauv paus. Pom nws tshwm sim nyob rau hauv nruj tswj cov xwm txheej uas ib tug neeg cinched lub velcro straps heev aggressively.

Breakout configurations tsim nyog hais ib yam nkaus thiab. MPO-rau-LC duplex breakouts cia koj txuas 100G hloov chaw nres nkoj rau cov laus 10G lossis 25G SFP- cov khoom siv. MPO-rau-SN thiab MPO-rau-MDC breakouts ua haujlwm tshiab dua- luv- mus txog cov ntawv thov hauv racks.

Kub cycling cuam tshuam rau connector kev ua tau zoo nyob rau lub sij hawm. Cov ntaub ntawv nthuav dav thiab cog lus. Rov ua dua mating cycles coj mus rau qhov chaw ferrule. Feem ntau cov tuam ntxhab ntsuas lawv cov khoom sib txuas rau 200-500 mating cycles yam tsawg kawg nkaus.

Rau lub hom phiaj - cov kev txuas tseem ceeb, qee tus neeg ua haujlwm sim txhua lub cable ua ntej xa mus. Lub sij hawm-domain reflectometer traces, insertion poob ntawm kev khiav hauj lwm wavelengths, pom qhov kawg -fim tshuaj xyuas. Siv sijhawm ntev dua. Tus nqi ntau dua. Tab sis kev ntes cov kab txuas txuas ua ntej nws mus nyob ua rau muaj teeb meem daws qhov sib txuas ntawm 2 AM.

Cov lus teb tseem yog. MPO rau MPO kiag li txhawb 100G. Tau txais nws los ua haujlwm ntseeg siab hauv kev tsim khoom yuav tsum tau saib xyuas cov ntsiab lus saum toj no.
