Tom qab:
Lub luag haujlwm ntawm SFP Transceiver nyob rau hauv tag nrho cov kho qhov muag kis tau tus mob txuas tseem ceeb heev, tab sis ntau yam teeb meem yuav tshwm sim hauv kev siv tiag tiag. Hnub no kuv yuav hais luv luv txog tias peb yuav tsum daws li cas yog tias koj qhov SFP Transceiver tsis ua haujlwm.
1. Ua ntej tshaj plaws, peb yuav tsum paub tias nyob rau hauv lub network fiber ntau kho qhov muag, yog tias SFP Transceiver tsis ua haujlwm, nws yuav ua rau tag nrho cov kev pabcuam MSAN, txhua qhov kev pabcuam broadband thiab lub suab tau cuam tshuam.
Feem ntau, yog tias SFP Transceiver ua tsis tiav, nws lub teeb txais kev ua haujlwm tseem zoo li qub, tab sis nws tsis tawm lub teeb ci lossis lub teeb ci tsis txaus. Yog tias qhov chaw nres nkoj kho qhov muag ntawm qhov kawg rov qab yog qhov teeb pom kev zoo ib txwm, thiab cov chaw nres nkoj kho qhov muag ntawm qhov rov qab kawg hloov teeb pom kev zoo li hauv qis, tag nrho cov ncej yuav raug cuam tshuam.
Lub sijhawm no, peb yuav tsum kaw qhov chaw nres nkoj kho qhov muag ntawm qhov tsis ua tiav ntawm SFP Transceiver ntawm qhov hloov pauv, yog li SFP Transceiver ntawm IPMB tsis tuaj yeem txais lub teeb pom kev, thiab lub rooj vag nram qab qhib thiab tuaj yeem txais lub teeb pom kev, lub kaw lus yuav hloov mus rau lub backplane.
Hauv cov txheej txheem no, peb yuav tsum them sai sai los qhib qhov chaw nres nkoj optical backplane, thiab tom qab ntawd tshawb xyuas qhov xwm txheej kho qhov muag ntawm lub pob taws. Yog tias nws pom tias cov xwm txheej ntawm tus tes hloov qhov chaw nres nkoj kho qhov muag tau poob thiab qhov kawg rov qab IPMB optical port yog online, ces IPMB optical port tau ua tsis tiav. Cov xwm txheej no yog qhov yooj yim, thiab koj tuaj yeem hloov tam sim ntawd.
2. Yog tias ob lub SFP Transceivers txuas nrog, tag nrho cov kab ntawv txuas tsis tuaj yeem ua haujlwm ib txwm muaj.
Hauv qhov no, koj tuaj yeem tshawb xyuas seb qhov laj thawj yog vim li cas rau SFP thiab cov khoom siv fiber ntau tsis sib thooj, qhov chaw nres nkoj raug sib txuas, lub tshuab xa hluav taws xob tau txais qis heev los yog siab dhau, tau txais lub zog kho qhov muag yog tsawg dhau lossis siab dhau, thiab SFP txuas nrog ntawm ob qho kawg tsis sib thooj.
Txhawm rau txiav txim siab rau qhov tshwj xeeb, tus thev naus laus zis xav kom ua tiav cov lus txib" tso saib interface transceiver" mus saib" Tswb cov lus qhia", thiab tom qab ntawd coj cov lus txib" tso saib interface transceiver verbose" txhawm rau soj ntsuam SFP. Nyob rau lub sijhawm no, koj tuaj yeem pom cov hluav taws xob tam sim no tau txais thiab tau txais cov khoom siv hluav taws xob rau qhov tseem ceeb, Lub neej ntawd qhov siab tshaj plaws thiab tsawg zog ua haujlwm. Tom qab ntawd peb yuav tsum tau ua cov txheej txheem sib txawv los ntawm cov ntaub ntawv sib txawv tau tso tawm:
TxPower Qis: Qhov no yog vim tias SFP xa cov paib tsis zoo, ua rau lub pob hlau tsis tuaj yeem lossis cov xov pov tseg tom qab qhov chaw nres nkoj nce. Hauv qhov no, qhov zoo ntawm cov khoom tsis xws luag. Koj tuaj yeem txiav txim siab tiv toj rau tus neeg muag khoom rau kev kho tom qab muag, lossis txawm tias hloov ncaj qha rau nws Cov Khoom Siv thiab.
TxPower High: Lub SFP hauv zos yog qhov yuam kev, ua rau SFP rov qab hlawv tawm vim tias qhov kev nruam siab tau txais hluav taws xob. Qhov no yog qhov xwm txheej phem tshaj plaws. Txhawm rau kom tsis txhob poob ntau dua, SFPs ntawm ob qhov kawg yuav tsum tau hloov lub sijhawm.
RxPower Tsawg: Tej zaum nws yog tias qhov chaw nres nkoj tsis nce los sis cov ntawv ntim tau muab pov tseg tom qab nce. Txoj kev coj ua yog los xyuas seb qhov kis tau mus deb tshaj qhov kev ntsuas ib txwm, thiab tom qab ntawd xyuas seb SFP thiab fiber ntau tus jumper puas lawm.
RxPower High: Nws yuav yog tias SFP yog SFP ntev-ntev, tab sis qhov tseeb kev sib kis tau luv heev thiab lub teeb liab tsis yog attenuated. Cov txheej txheem coj ua yog los ua kom muaj lub ntsej muag kho qhov muag ntawm lub ntsej muag kho qhov muag.
Xaus:
Tom qab SFP tau muab tso rau hauv qhov chaw nres nkoj thiab ua tiav kev sib txuas, cov lus ceeb toom txog kev sib kis lossis tau txais lub zog kho qhov muag yuav tsum kuaj xyuas kom tsis txhob muaj tsheb lossis txawv txav SFP tshwm sim los ntawm qis dhau lossis muaj zog dhau.
