Txheej txheem cej luam ntawm OSFP Modules
OSFP (Octal Me Form -}}}}}}} Kev tseem ceeb hauv lub sijhawm niaj hnub no xav tau. Cov modules no muaj kev tshwj xeeb bandwidth thiab efficiency, ua rau lawv nrhiav tau ntau tom qab rau ntau yam kev siv. Los ntawm kev siv dag cov thev naus laus zis xws li Pam4 kev hloov kho, OSFP modules tuaj yeem pab txhawb cov ntaub ntawv zoo tshaj plaws ntawm li 800 gbps. Lub peev xwm no ua rau lawv zoo tshwj xeeb - ruited hauv cov ntaub ntawv hauv cov ntaub ntawv uas muaj qhov chaw nrawm nrawm yog qhov tseem ceeb. Tsis tas li ntawd, tus qauv OSFP yog tsim los txhawb kev sib cuam tshuam nrog ntau lub cev thiab txo cov kev ua haujlwm ntawm lub network ua haujlwm.
Cov yam ntxwv tseem ceeb ntawm OSFP Modules
Ib qho ntawm cov khoom seem ntawm OSFP modules yog lawv tus qauv, uas suav nrog txoj kab kev xav kho kho kho kho kho. Cov qauv tsim no tso cai rau cov ntaub ntawv ceev xws li 200 Gbps rau 400 Gbps, ua cov qauv xaiv tau zoo uas yuav tsum tau ua kom cov ntaub ntawv muaj zog. Ntxiv nrog rau lawv qhov kev nrawm nrawm, OSFP cov qauv yog sib xyaw hauv qhov loj me, uas yooj yim nrog cov txheej txheem kev teeb tsa thiab cov txheej txheem saib xyuas. Lawv qhov ntev me me tso cai rau kev tuav yooj yim thiab kev sib koom ua rau rau hauv cov tshuab uas twb muaj tam sim no. Ntxiv mus, cov qauv no txhawb nqa cov kev hloov pauv kub, ua kom sai dua cov kev hloov kho sai yam tsis muaj downtime, uas yog qhov tseem ceeb rau kev tswj cov haujlwm txuas ntxiv. Thaum piv rau qsfp - DD modules los ntawm kev tswj hwm cov ntaub ntawv zoo ib yam thiab kev xaiv ua chaw nres nkoj, ua rau lawv xaiv tau zoo dua rau cov ntaub ntawv niaj hnub no.
Kev sib cuam tshuam thiab kev tsim kho tshiab
OSFP Zov - Daim Ntawv Cog Lus Ntawm Cov Lus Cog Tseg (MSA) yog cov qauv tseem ceeb uas ua rau cov qauv tshwj xeeb rau cov khoom lag luam ntau ntawm cov khoom lag luam. Qhov txheej txheem no tseem ceeb heev li nws txo cov khoom siv tsis zoo thiab cov sawv cev hloov tshiab hauv qhov chaw kho qhov muag. Los ntawm adhering rau cov specifications no, cov chaw tsim khoom tuaj yeem ua kom tau lawv cov khoom lag luam ua haujlwm nrog cov haujlwm ntawm cov haujlwm sib xyaw ua haujlwm.
Kho qhov muag Transceer
Ntawm qhov tseem ceeb ntawm OSFP Module txoj haujlwm yog nws lub luag haujlwm kho qhov tseem ceeb hauv kev hloov hluav taws xob rau hauv kev sib kis hluav taws xob rau cov khoom siv fiber ntau. Cov txheej txheem hloov dua siab tshiab no suav nrog kev siv cov khoom tseem ceeb ntawm laser dodes thiab photodetectors, uas ua haujlwm ua ke los pab txhawb cov ntaub ntawv hloov tshiab. Ib qho ntxiv, OSFP cov kev hloov pauv feem ntau koom nrog kev nce qib siab heev xws li wavelength division accexing (WDM) thiab digital teeb liab ua (DSP). Cov thev naus laus zis tseem ceeb txhim kho kev ua tau zoo thiab kev ntseeg tau ntawm cov modules, tshwj xeeb hauv high- bandwidth cov ntaub ntawv uas cov ntaub ntawv ntseeg tau thiab ceev yog qhov tseem ceeb.
Kev siv fiber ntau
OSFP cov qauv yog tsim los siv ob qho tib si {{0} {} {} hom fiber ntau (MMF) kom tau raws li ntau yam kev xav tau. Sing - hom fiber ntau yog ua tau zoo rau kev siv tau ntev, kev tso cai rau cov ntaub ntawv sib kis tau zoo tshaj plaws dhau mus. Ntawm qhov tod tes, mult - hom fiber ntau yog qhov zoo tagnrho, muab cov kev sib txuas siv nrawm nrawm rau cov neeg sib txawv ib puag ncig. Qhov no dual - Kev siv Fiber ntau dua uas ntseeg tau tias OSFP hloov tuaj yeem hloov kho ntau yam, ua rau lawv xaiv cov kev daws teeb meem tam sim no.
Nkag Siab Duplex LC thiab MPO Innstors hauv QSFP Networking
Duplex lc connector thiab mpo (multi - Fiber ntau yog ob qho kev sib txuas (quad}} qhov tseeb pluggable) modules. Ntawm no yog ib qho luv luv qhia ntawm txhua tus:
Duplex Lc Txuas
Kev Tsim: Duplex Lc txuas yog daim ntawv me me - qhov sib txuas nrog uas siv lub tshuab ua kom sib txuas rau kev sib txuas. Lawv feem ntau txuas ob lub fibers (ib qho rau kev xa mus thiab ib qho rau tau txais).
Kev siv: feem ntau siv nyob rau hauv ib qho - hom thiab multimode fiber ntau daim ntawv thov, lawv feem ntau pom nyob rau hauv cov chaw zov me nyuam thiab chaw lag luam.
Qhov Zoo: Kev siv qhov loj me, yooj yim ntawm kev siv, thiab kev ua tau zoo ua rau lawv haum rau high- qhov kev siv ua kom txaus.
MPO Txuas
Tsim: MPO cov tsev txuas tau tuaj yeem haum ntau yam Fibers (feem ntau 12, 24, lossis ntau dua) hauv ib qho txuas. Lawv siv lub laub - Rub mechanism rau cov ntxig yooj yim thiab tshem tawm.
Kev Siv: Qhov zoo tagnrho rau high - qhov kev siv ua kom txaus siab, xws li hauv cov chaw hauv cov ntaub ntawv uas muaj tsawg. Lawv feem ntau tau siv los txuas rau QSFP cov modules uas xav tau ntau cov fibers rau high- ceev cov ntaub ntawv kis.
Cov txiaj ntsig zoo: qhov siab ceev thiab muaj peev xwm txuas ntau cov fibers ntawm ib zaug ua rau mpo cov twj sib txuas ua tau zoo rau loj- nplai rho tawm.
QSFP Modules
Kev ua haujlwm: QSFP cov modules yog tsim los txhawb kev siab siab {}} ceev cov ntaub ntawv kis tau (txog 100 gbps lossis ntau dua) thiab tuaj yeem siv ob qho tib si kev sib txuas ntawm MPO nyob ntawm daim ntawv thov.
Kev sib txuas: Thaum siv MPO txuas, qsfp modules tuaj yeem txuas rau multi- fiber ntau lub taub hau yog siv rau kev sib txuas rau rau qhov kev sib txuas lus.
Lub ntsiab
Hauv cov ntsiab lus, Duplex LC txuas yog qhov tsim nyog rau kev sib txuas nrog cov plaub hau tsawg dua, thaum MPO cov twj sib txuas yog qhov zoo tshaj plaws rau kev xav tau ntau yam khoom siv. Ob hom kev sib txuas no tuaj yeem siv nrog QSFP cov qauv, nyob ntawm cov kev xav tau kev sib tham tshwj xeeb.
Kev ntseeg tau: Kev ntsuas zoo ntawm OSFP MODULES hauv cov ntaub ntawv kis
Kev ntsuas zoo ntawm OSFP cov modules cuam tshuam txog kev ntsuas nruj kom ntseeg tau kho qhov muag thiab kev ua tau zoo hauv cov ntaub ntawv sib kis.
Kev Ntsuas Cov Ntsiab
Cov kev xeem tseem ceeb soj ntsuam cov kev ntsuas kho qhov muag xws li cov kev ntsuas poob thiab cov tsheb ciav hlau uas simulate - ntiaj teb cov xwm txheej.
Ua raws li cov qauv kev lag luam
Ua raws li cov qauv kev lag luam tsim los ntawm lub cev zoo li cov koom haum kev lag luam kev lag luam (TIA) thiab lub koom haum ntawm cov tshuab hluav taws xob (IEEE) yog qhov tseem ceeb rau kev sib cuam tshuam thiab kev ua tau zoo.
Kev coj ua zoo tshaj plaws rau kev sim
Cov kev coj ua zoo tshaj plaws rau kev sim muaj xws li siv cov cuab yeej siv tshuab, ua cov tshev ua raws cai, thiab ua cov kev ntsuas ib puag ncig.
Qhov tseem ceeb ntawm cov ntaub ntawv
Tswj cov ntaub ntawv ntxaws ntxaws ntawm cov txheej txheem sim ua kom muaj kev ntseeg siab thiab ua tau zoo hauv cov ntaub ntawv niaj hnub no.
Yuav ua li cas txuas OSFP module hauv cov ntaub ntawv chaw
Txhawm rau txuas lub OSFP (Octal me me -}}}}}}}}}}}}} tus qauv ntsaws, ua raws cov kauj ruam:
1. Txheeb xyuas lub OSFP module: nrhiav lub OSFP module thiab ua kom nws haum nrog koj cov khoom siv sib txuas.
2. Fais fab nqes khoom: Ua ntej txuas rau OSFP module, zog cia txhua yam khoom siv cuam tshuam los tiv thaiv kev sib xyaw ua kom hluav taws xob muaj kev phom sij thiab ua kom muaj kev nyab xeeb thaum lub sijhawm teeb tsa.
3. Tshem cov hmoov av plua plav: tshem cov hmoov av kaus mom los ntawm ob qho kawg ntawm OSFP module raws li los ntawm cov chaw nres nkoj ntawm cov khoom siv network uas koj yuav muab tso rau nws.
4. Tswvyim: Ua tib zoo ua kom haum rau OSFP module nrog nws cov chaw nres nkoj OSFP ntawm cov khoom siv networking thiab maj mam muab ntxig rau kom txog thaum nws nyob ruaj khov.
5. Kev sib txuas nyab xeeb: ib zaug tso, muaj kev sib txuas tau yooj yim tab sis khov kho kom ntseeg tau tias kev sib koom ua ke uas tsis muaj qhov khoob lossis xoob.
6. Fais txog cov khoom siv: tom qab ua kom txhua yam muaj kev sib txuas tau ua, muaj zog rau koj cov khoom siv network thaum pom tias muaj cov lus tsis raug lossis cov ntsuas ntawm cov khoom sib txuas tsis raug.
7. Kuaj thiab Tshawb Xyuas: Thaum siv sijhawm, ua cov txheej txheem kuaj xyuas kom paub tseeb thiab ua haujlwm tau zoo ntawm OSFP module.
Thov nco ntsoov tias cov ntsiab lus tshwj xeeb rau kev sib txuas ntawm OSFP qauv yuav sib txawv raws li koj cov ntaub ntawv teev cov ntaub ntawv teeb tsa thiab cov ntaub ntawv network. Yuav tsum tau tham cov ntaub ntawv tsim chaw thiab ua raws cov kev coj ua zoo tshaj plaws rau kev txhim kho kho qhov muag transce nyob rau hauv ib puag ncig cov ntaub ntawv ib puag ncig.
