Taw qhia: Kev nrawm nrawm xav tau cov cai tshiab Fiber
Tsiv mus rau 400G thiab 800G cov chaw zov me nyuam txhais tau tias koj txoj kev fiber ntau yuav tsum yog ze li ntawm zoo meej. Laus lossis tsis zoo - cabling zoo ua rau muaj teeb meem loj. IEEE 802.3 cov qauv qhia tias cov teeb liab poob nyiaj tam sim no nruj heev - feem ntau qis dua 1.5dB. Cov neeg muab kev pabcuam huab tiag pom kev ceev poob mus txog 30% thaum siv cov cabling qub.
Cov teeb meem tseem ceeb suav nrog kev txwv tsis pub dhau, teeb liab distortion (dispersion), hloov mus rau MPO tshiab-24 connectors, tau txais txoj cai polarity, thiab txiav txim siab ntawm OM5 multimode thiab ib hom fiber ntau.
Xaiv OM5 Multimode lossis Tib -Mode Fiber
Ua ntej, paub meej txog koj qhov kev ncua deb thiab kev xav tau ceev. OM5 multimode ua haujlwm zoo rau kev khiav luv luv. Nws tso cai rau koj xa plaub lub wavelengths tshaj ib fiber ntau rau 400G, ncav cuag 150 meters nrog attenuation nyob rau hauv 3.0 dB / km. Tib - hom fiber ntau muaj qhov poob qis dua (tsawg dua lossis sib npaug li 0.4 dB / km) thiab ua rau kev ncua deb heev. Kuv xav kom siv OM5 hauv racks (hauv qab 100m) kom txuag tau tus nqi.
Xaiv ib qho - hom rau kev sib txuas ntawm cov keyboards tshaj 500m, tshwj xeeb tshaj yog rau 800G. ANSI/TIA-492AAAE tus qauv txhais OM5 kev ua tau zoo. Tshaj li 500m lossis rau 800G siv, tib hom - yog qhov koj xaiv nkaus xwb. Txawm hais tias ib leeg-hom nqi ntau dua, nws feem ntau txuag nyiaj dhau sijhawm vim tias cov optics rau qhov ntev yog pheej yig dua.
Txhim kho rau MPO-16 thiab MPO-32 Connectors
400G-SR8 siv 16 fibers, thiab 800G xav tau 32. Nws yog qhov tseeb tias peb yuav tsum txav mus dhau MPO qub-12 connectors. Tshiab MPO-16 thiab MPO-32 connectors haum ntau fibers nyob rau tib qhov chaw. Piv txwv li, ib chav tsev khib nyiab tam sim no tuaj yeem tuav cov cassettes uas tswj 144 fibers. Txhawm rau lis polarity yooj yim, kuv xav kom cov cassettes nrog built-in polarity flip modules.
Rau 800G, txhua qhov kev sib txuas yuav tsum muaj tsawg dua 0.35dB qhov poob. Kev tiv thaiv koj qhov kev ua tau zoo txhais tau hais tias siv cov khoom sib txuas uas ua tau raws li IEC 61753-1 cov qauv sib khi kom tsis txhob muaj plua plav tawm. Ultra-slim tsho cables (xws li 1.6mm txoj kab uas hla) yog ib qho kev xaiv ntse-lawv khoov kom ruaj ntseg hauv qhov chaw nruj. Tsis tas li ntawd, kev sib txuas ncaj qha kev daws teeb meem txuag tau ntau qhov chaw piv rau cov kab sib txuas sib txuas.
Tsim High-Density Fiber Pathways
Kab laug sab-cov teeb tsa nplooj xav tau ntau cov fiber ntau txuas ntawm cov khaubncaws sab nraud povtseg- piv txwv li 72: 1 muaj ntau. Ua raws li BICSI 002 cov lus qhia: tsis txhob sau cov tais kab ntau tshaj 40%. Loj 864-fiber trunks tuaj yeem thaiv cov cua ntws. Cov pob me me (micro-cabling) pab ua kom txias; zoo airflow designs yuav txo tau kub txog li 3 degree. Siv cov cuab yeej txuag chaw xws li 0.5U ntsug tus tswj hwm uas txhawb nqa 96 chaw nres nkoj.
Npaj rau cheeb tsam cabling: muab cov ntsiab lus sib sau lossis cov thawv sib txuas txhua 12 racks. Thiab tsis txhob hnov qab MTP-rau-LC breakout harnesses-lawv ua tib zoo txuas cov qub 100G iav rau 400G / 800G hloov tshiab.
Ua kom lub teeb liab huv ntawm kev kub ceev
Cov teeb liab zoo yog txhua yam rau 800G. Khaws Polarization Hom Dispersion hauv qab 0.1 ps/√km. Cov laus fiber ntau degrades thiab xav tau ntau dua OSNR- xyuas qhov no nrog OTDR xeem. Txo kev xav rov qab los ntawm kev siv cov khoom sib txuas nrog lub cev sib tiv tauj (APC) polishes (lub hom phiaj rau kev cuam tshuam tsawg dua lossis sib npaug rau -55dB).
Ntxuav txhua qhov txuas zoo kawg nkaus nrog IBC- cov cuab yeej pom zoo. Rau ib qho - hom khiav tshaj 2km, tswj chromatic dispersion. Saib xyuas microbends-lawv ua rau lub zog poob, yog li ua raws li EIA/TIA FOTP-34 cov lus qhia. Thaum kawg, kuaj qhov poob ntawm txhua qhov chaw thaj chaw.
Kev tsiv teb tsaws yam tsis tso tseg kev ua haujlwm
Ib kauj ruam -los ntawm- kauj ruam hloov kho yog txoj hauv kev mus.
Theem 1: Ntsuas tag nrho cov fiber ntau uas twb muaj lawm nrog OLTS thiab OTDR.
Theem 2: Txhim kho cov tshiab ua ntej- txiav cables nyob ib sab ntawm cov qub.
Theem 3: Ntsuam xyuas cov kev sib txuas tshiab ntawm qhov nrawm nrawm (53.125 Gbaud) nrog kev kuaj xyuas me ntsis yuam kev.
Theem 4: Txav tsheb mus rau cov cables tshiab uas siv cov ntse patch panels. Cov xwm txheej tiag tiag qhia txog 400G tsiv teb tsaws ua tiav hauv 48 teev siv MPO-24 pob tw.
Npaj kom zoo kom tsis txhob tso cov fiber ntau. Tsim koj lub network kom khiav 100G, 400G, thiab 800G ib sab. Thiab siv cov cuab yeej zoo: MTP-24 polarity checkers thiab 33 GHz network analyzers.
Npaj rau 1.6T thiab Yuav Ua Li Cas Tom Ntej
Kev hloov pauv loj tom ntej yog Co-Packaged Optics. CPO muab lub tshuab kho qhov muag rau ntawm lub nti hloov, txiav fiber ntau suav. Yav tom ntej ib leeg - hom fibers (xws li SMF-28) thiab hollow-core fibers tshiab yuav ua haujlwm ntawm 1.6μm wavelengths.
Qhov chaw-Division Multiplexing yuav siv cov fiber ntau ntau (piv txwv li, 7-core) kom txav tau cov ntaub ntawv ntxiv. Rau kev sib txuas luv luv hauv qab 3 meters, polymer waveguides tuaj yeem hloov cov cables. Cov khoom sib txuas kuj tseem yuav hloov mus rau hom ntawv xws li MXC, tuav txog 512 fibers. Cov txheej txheem pawg (xws li OIF) twb tau txiav txim siab 800G-LR thiab 1.6T interfaces. Kuv cov lus qhia: tsim lub neej yav tom ntej- npaj teeb-tawm 25% ntawm cov fibers uas tsis siv raws li "tsaus fiber ntau" rau kev nthuav dav tom qab.
Xaiv tus khub zoo rau yav tom ntej
Kev xaiv tus khub zoo thiab cov khoom lag luam yog qhov tseem ceeb rau lub chaw khaws ntaub ntawv uas kav ntev. Hauv kuv qhov kev xav, Glory Optics muaj qhov ua tiavMTP/MPO siab -cov kev daws teeb meem cabling. Los ntawm qis- cov khoom sib txuas uas tau raws li cov peev nyiaj poob qis, mus rau MPO-12/16/24/32 cov pob tw ua ntej txiav thiab cov cassettes modular ua rau 400G / 800G hloov kho dua tshiab, lawv cov kab sib tw daws txhua qhov teeb meem uas peb tau tham.
Los ntawm kev siv cov pov thawj, siab -qhov ua tau zoo nrog rau pem hauv ntej- saib tsim, koj tuaj yeem tsim kom muaj zog, hloov tau fiber ntau sib txuas npaj kom loj hlob ntawm 400G thiab 800G mus rau 1.6T era.
