24-Fibre Lub Cev Kab Mob - Kev Kho Kom Zoo rau 10-40-100G Kev Hla Tebchaws
Nyob hauv cov chaw zov me nyuam, cov ntaub ntawv lag luam zoo tshaj plaws yuav tsum xa, kev ua thiab khaws cia. Fiber optic links yog qhov tseem ceeb rau kev muab cov bandwidth thiab kev ceev kom tau xa cov ntaub ntawv loj loj rau thiab los ntawm ntau qhov chaw. Txoj kev kis tau sai ntawm cov tub ntxhais cov keyboards yog nce thiab qaum qhov kev lag luam yog muaj kev cuam tshuam loj heev nyob rau hauv cov nyiaj ntawm fiber optic cabling. Lub 24-fiber ntau thiab sib txuas ntawm kev sib txuas lus, muab cov ntaub ntawv qhia txog kev lag luam rau cov lag luam kom zoo los ntawm 10G txog 40 / 100G, muab txoj cai 10-40-100G migration. Vim li cas thiaj hais li ntawd? Nco ntsoov nyeem thiab koj yuav pom cov lus teb.
Lub IEEE tau pom zoo rau 802.3ae tus qauv siv 10G ntau tshaj qhov siv fiber ntau txuas (ib qho kev xa mus thiab lwm qhov tau txais) hauv xyoo 2002. Xyoo 2010, IEEE tau lees txais tus qauv 802.3b rau 40G thiab 100G los ntawm kev siv tib lub tshuab hlwb hlau, lossis ntau yam lanes ntawm fiber ntau kis ntawm tib lub ceev. Khiav 40G yuav tsum muaj 8 fibers, nrog 4 fibers txhua kis ntawm 10G thiab 4 fibers txhua tau txais thaum 10G, thaum khiav 100G yuav tsum tau tag nrho 20 fibers, nrog 10 kis thaum 10G thiab 10 tau txais 10G. Ob qho scenarios hu rau high-density multi-fiber MPO connectors.
Rau 40G, siv 12-fiber MPO connector. Vim hais tias tsuas yog 8 optical fibers yuav tsum tau, kev siv 40G tsuas siv cov 4 sab laug thiab 4 txoj cai fibers ntawm 12-fibre MPO connector, hos lub puab tsaig 4 lub puab tsaig uas tsis siv. Ua kom khiav 100G, tus 24-fiber MPO connector yog pom zoo, nrog 20 daim txiag ntsej muag nyob nruab nrab ntawm qhov sib txuas kis thiab tau txais ntawm 10G thiab 2 sab saum toj thiab hauv qab fibers ntawm sab laug thiab txoj cai tsis siv.
Raws li IEEE 802.3b txuj, multimode optical fiber txhawb cov 40G thiab 100G txuas txuas ntev txog 150 meters thaum siv OM4 optical fiber thiab mus txog 100 meters thaum siv OM3 optical fiber. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ib hom fiber ntau kuj siv tau los siv khiav 40G thiab 100G rau ntau qhov chaw siv wavelength division multiplexing (WDM). Thaum qhov no yog qhov zoo rau cov ntawv thov ntev-ntev, feem ntau cov ntaub ntawv siv cov ntaub ntawv nruab nrab ntawm tsawg dua 150 meters, ib hom fiber ntau tsis tau them vim yog tus nqi kim. Tooj liab twinax cable kuj muaj peev xwm txhawb 40G thiab 100G tab sis tsuas yog mus ncua kev 7 meters.
Kev siv 24-fiber ntau lub cev cab yuav pab txhawb 10G, 40G thiab 100G. Rau kev siv 10G, txhua tus 24 fibers yuav siv tau los xa 10G, rau tag nrho cov kev sib txuas 12. Rau 40G daim ntaub ntawv, uas yuav tsum tau muaj 8 fibers (4 kis thiab 4 tau txais), 24-fiber ntau lub cev cable muab tag nrho peb ntawm peb 40G kev sib txuas. Rau 100G, uas yuav tsum muaj 20 fibers (10 kis thiab 10 tau txais), 24-fiber ntau lub cev cable muab ib qhov txuas 100G txuas. Ib co kev pab cuam ntawm kev siv 24-fiber ntau lub cev cab muaj npe hauv qab no.
Siv tshaj plaws ntawm Fiber
Raws li hais dhau los, 40G siv 8 fibers ntawm 12-fiber MPO, tawm 4 fibers tsis siv. Thaum siv lub tshuab 12-fiber ntau lub cev, cov 4 fibers tib tsis siv. Piv txwv li, peb siv 40G txuas rau peb cais 12-fiber ntau lub cev cab ua rau tag nrho cov 12 fibers uas tsis siv, lossis 4 fibers tsis siv rau txhua lub cev. Nrog rau kev siv 24-fiber ntau lub cev cab, cov thawj coj ntawm cov ntaub ntawv yeej tau siv tag nrho cov fiber ntau thiab siv lawv cov peev tag nrho. Khiav peb, 40 G mus dhau ib lub cev 24-fiber kab hlau siv tag nrho 24 fibers ntawm lub cev pob tw. Cov recoups no 33% ntawm cov fibers uas yuav ploj nrog 12-fiber ntau lub cev cab, muab ib tug zoo dua tuaj ntawm kev peev.
Reduced Cable Congestion
Tsawg tsawg dua cov kev sib txuas hauv cov kab tsheb uas twb muaj neeg coob dhau lawm yog lwm yam kev pab cuam ntawm lub cev 24-fiber ntau. Qhov chaw yog qhov chaw nyob hauv cov chaw khaws xov xwm, thiab cov kab txuas qhua rau congested yuav ua rau kev tswj kev lag luam yooj yim dua thiab ua rau huab cua tsis zoo yuav tsum tau tswj kom muaj kev ua kom txias dua thiab kev siv zog ntxiv. Cov kab mob 24-fiber ntau lub cev muaj zog loj tshaj 12-fiber ntau lub cev cab. Rau daim ntawv 40G, nws yuav siv peb 12-fiber ntau lub cev cab los muab tib lub xov tooj txuas raws li ib lub cev 24-fiber kab, uas xav tau 1.5 npaug ntau qhov chaw.
Yooj Yim Tus Kab Nkag Yooj Yim
Lub 24-fiber ntau chaw fiber ntau thiab cov khoom siv sib txuas sib txuas muaj kev yooj yim thiab kim-zoo migration kev ntawm 10G rau 40 G thiab 100G. Nrog 24-fiber ntau lub cev cab zoo txhawb nqa tag nrho peb daim ntawv sau npe, kho kom zoo dua cov cab vaj tse yooj yim xws li kho lub hydra cables los yog cassettes thiab thaj hlua rau cov khoom siv.
Lub 24-fiber ntau chaw nruab nrab thiab kev sib txuas lus sib txuas lus pabcuam cov ntaub ntawv qhia cov haujlwm zoo thiab muaj txiaj ntsim zoo txhawb nqa hnub no kev ua haujlwm siab-ceev. Nrog 24-fibre lub cev cables uas tshem tawm qhov xav tau kom tiav thiab complex reconfiguration txhua txoj kev los ntawm qhov hloov mus rau cov cuab yeej, nws muaj ib qho yooj yim, them nqi zoo rau kev kho dua tshiab los ntawm 10 G, 40G thiab 100G nrog cov peev nyiaj tsawg thiab kev khiav hauj lwm .
