Yuav ua li cas txiav txim siab qhov sib xws ntawm cov khoos phis tawm tsis ntau

Vim li cas thiaj siv tau lub khoos phis tawm kho qhov muag kom nrov?

1. Hauv txhua lub network, muaj ntau txoj kev xaiv rau cov qauv kho qhov muag tau tshaj

Yog tias koj xaiv tooj liab tub ntxhais network, ib hom fiber ntau, fiber ntau multimode, kev sib xyaw ntawm ob lossis lwm qhov kev sib koom tes, tus nqi ntawm cov kho qhov muag zoo li tus nqi pheej yig heev, haum rau koj cov khoom siv, thiab nws tsis tas yuav cov qauv kho qhov muag optical ntawm lub hom.

2. Kev sib tw ntau dua li siv cov qauv kho qhov muag

Hom nyhuv yog qhov tshwm sim ntau. Qhov no feem ntau qhia tau tias cov neeg siv yuav siv nyiaj ntawm cov hom uas lawv tau yuav, tsis yog khoom nkaus xwb. Yog tias koj siv nyiaj ntau dua, nws tsis yog' t txhais tau tias cov khoom lag luam tuaj yeem muab cov khoom lag luam zoo rau koj. Yog tias koj xav txhim kho kom tiav koj hom kab ke, xws li siv cov qauv kho qhov muag tau tshaj tawm, koj tuaj yeem txuag tau ntau txhiab nyiaj thiab ua tiav cov txiaj ntsig zoo ib yam.

3. Warranty nrog kev siv tau ntev dua thiab muaj kev pabcuam zoo dua

Tom qab kev pab cuam muag khoom yog qhov tseem ceeb tshaj plaws, raws li cov ntaub ntawv nrog cov khoom lag luam feem ntau. Hom kev sib raug zoo thiab lub sijhawm tiv thaiv ntev. Qhov zoo ntawm qhov kho qhov muag hluav taws xob tuaj yeem cuam tshuam qhov sib kis ntawm cov kab hluav taws xob txuas. Txawm hais tias qhov zoo ntawm qhov qub optical module yog qhov zoo heev, nws tus nqi yog kim heev. Tam sim no, cov khoos phis tawm ntawm cov khoos phis tawm tau muab los ntawm ntau cov chaw muag khoom tau muab piv nrog cov qauv kho qhov muag qub, thiab tus nqi tau zoo heev, uas tuaj yeem pab cov neeg siv txuag ntau tus nqi.

Yuav ua li cas txiav txim siab qhov sib xws thiab qhov ua tau zoo ntawm cov qauv kho qhov muag kho tsis tau?

Nyob rau hauv loj-teev network kis system, txuag nqi yog ib qho tseem ceeb heev, tshwj xeeb tshaj yog thaum ib tug loj tus naj npawb ntawm optical module yog xav tau, tshwj xeeb tshaj yog cov thawj optical module. Yog li ntawd, tus qauv siv tau tshwm sim los daws cov teeb meem zoo no. Yuav ua li cas los txiav txim siab qhov ua tau zoo ntawm cov khoos phis tawm ntawm cov kho qhov muag?

1. Peb cov qauv puas muaj cov ntaub ntawv kuaj xyuas cov interface (ddmi) teev hauv sff-8472 tus qauv?

Ssff-8472 tus qauv yog qhov tseem ceeb los txiav txim qhov zoo thiab ua haujlwm ntawm cov qauv kho qhov muag tau tshaj. Nws tau tsim los ntawm SFF pawg los txhais cov ntaub ntawv kuaj xyuas cov interface (ddmi) ntawm cov kho qhov muag, uas tuaj yeem pab peb nkag siab txog cov kev ntsuas ntawm kho qhov muag ntawm lub sijhawm. Ddmi, tseem hu ua DDM lossis DOM, muaj lub tswb ua haujlwm thaum ib lossis ntau cov ntaub ntawv ntau dua li cov qauv ntsuas tau teev tseg los ntawm cov chaw tsim khoom.

DDM xyuas tsis

2. Puas yog peb lub module puas ua txhaum thaj chaw ua haujlwm?

Kev txhaum qhov chaw muaj nuj nqi tuaj yeem pab cov engineers nrhiav teeb meem, kho qhov kho qhov muag kho tau nrawm thiab txo lub sijhawm qis.

Yog tias qhov sib txuam kho qhov muag tau muaj cov ntaub ntawv kuaj xyuas kev ua haujlwm (DDM), peb tuaj yeem siv DDM los tshuaj xyuas txhua qhov ntsuas ntawm qhov kho qhov muag ntawm lub ntsej muag, xws li cov khoom siv hluav taws xob kho qhov muag, virtual channel txuas (VCC), thiab lwm yam, kom txiav txim siab qhov txhaum taw tes rau hauv lub txuas txuas.

3. Puas yog peb tus qauv ntsuas dhau qhov ua tiav kev txheeb xyuas qhov tseeb?

Txoj kev sib xyaw xav tau raug sim ntawm lub hloov mus saib xyuas qhov ua haujlwm ntawm tus qauv hloov kho, uas yog tib txoj kev los txiav txim siab qhov kev ua haujlwm ntawm qhov kho qhov muag hloov kho. Feem ntau, qhov siab dua cov qib kho qhov muag tau ua tiav.

4. Yuav ua li cas los ntsuas tus nqi ntawm cov qauv kho qhov muag sib xws?

Txoj kev hloov ntawm qhov hloov pauv yuav raug ua ua ntej kev hloov kho lub teeb tsa kom pom tseeb tias txhua qhov module tuaj yeem ua tiav 100%. Qhov zoo ntawm qhov kho qhov muag hluav taws xob tuaj yeem cuam tshuam qhov sib kis ntawm cov kab hluav taws xob txuas. Txawm hais tias qhov zoo ntawm qhov qub optical module yog qhov zoo heev, nws tus nqi yog kim heev. Tam sim no, cov khoos phis tawm ntawm cov khoos phis tawm tau muab los ntawm ntau cov chaw muag khoom tau muab piv nrog cov qauv kho qhov muag qub, thiab tus nqi tau zoo heev, uas tuaj yeem pab cov neeg siv txuag ntau tus nqi.

Hauv kev sib txuas ntawm cov network, muaj ntau txoj kev tuaj yeem ntawm kev tsis sib haum ntawm kev hloov thiab cov ntsuas hluav taws xob. Feem ntau hais lus, muaj tsib lub ntsiab: jumper txhaum ntawm hloov; kev sib koom ua ke kev ua haujlwm tsis ua haujlwm; loj kho qhov muag qhov teeb meem tshwm sim los ntawm qhov nce ntawm jumper; mismatch ntawm cov tshiab kho qhov muag; hloov qhov ua haujlwm tsis ua haujlwm. Pib ntawm cov xwm txheej no los ntsuam xyuas qhov ua tsis ua tiav.

Yuav ua li cas los daws qhov tsis sib xws ntawm kev hloov kho qhov siv hluav taws xob hauv cov xov hluav taws xob?

Cov kauj ruam xeem yog raws li nram no:

Hloov lub jumper thiab hloov kho, thiab lub network tseem poob qis tom qab kev ua haujlwm, thiab ua qhov kev xeem rau theem tom ntej;

Hloov lub ntsej muag kho qhov muag tsis pom kev thiab rov kho lub ntaus ntawv, tab sis tseem tsis hloov;

Los ntawm kev siv hluav taws xob pom ntawm lub teeb pom kev zoo, tom qab paub tseeb tias nws yog qhov qub, hloov kho rau hauv pem teb ntawm qhov kev txhaum ua txhaum, thiab qhov txhaum tseem muaj.

Los ntawm peb yam kev ntsuas, qhov txhaum tseem tuaj yeem daws' t daws kev sib tw. Qhov chaw nres nkoj teeb tsa ntawm cov tub ntxhais thiab cov khoom hloov hauv pem teb tuaj yeem paub tseeb. Ob qhov chaw nres nkoj kho qhov muag tau yuam kom tswj hwm hauv 1000m hom, thiab raws tu qauv yuav cia li sib tham. Tom qab khiav mus rau ib lub sijhawm, kev ua yuam kev ntau zaus yuav tshwm sim. Tom qab kev txheeb xyuas ntawm qhov teeb meem no, nws tuaj yeem xaus lus tias qhov tsis ua tiav ntawm kev cai ntawm cov qauv uas siv los ntawm ob lub ntsuas hluav taws xob ua rau chaw nres nkoj qis.

Txhawm rau paub tseeb tias qhov ua tiav ntawm qhov tsis ua tiav, koj tuaj yeem sim los hloov ntau cov qauv, thiab sim los ntawm cov khoom siv hluav taws xob thiab cov hloov kho qhov muag. Tom qab ntawd hloov ob khub ntawm cov kho qhov muag, ntsig txog txuas rau qhov hluav taws xob cuam tshuam ntawm ob lub pob hluav taws xob, thiab teeb tsa ob lub 100MB hluav taws xob cuam tshuam, qhov txhaum yuav tsum tshem tawm tag nrho thiab yuav tsis rov ua dua.

Cov teeb meem ntawm kev tsis sib haum ntawm cov hloov pauv tshiab thiab qub thiab cov khoos phis tawm kho qhov muag yuav tsum tau them sai sai rau hauv cov xov hlau, thiab nws tsis nyuaj los daws. Cov teeb meem tuaj yeem daws tau zoo los ntawm kev siv qhov hloov pauv kho qhov muag, teeb tsa hluav taws xob sib xyaw thiab yuam 100m. Nws yuav tsum raug sau tseg tias kev siv kho qhov muag siv yuav tsum yog tib yam qauv; 100m yuav tsum tau yuam kom teeb tsa rau ob chav hluav taws xob cuam tshuam; tsis siv neeg kev sib tham tau hom yuav tsum raug muab tso tseg rau txoj kev teeb tsa ntawm ib qho kev sib tshuam hluav taws xob.

Muaj peb lub hauv paus los txiav txim siab seb qhov khoos phis tawm ntawm cov khoos phis tawm puas yog ntseeg tau lossis tsis txaus

1. Cov ntaub ntawv kuaj xyuas cov interface (ddmi) teev hauv sff-8472 tus qauv

2. Txhaum qhov chaw muaj nuj nqi

Hauv qhov kho qhov muag fiber txuas, qhov chaw txhaum tuaj yeem pab tib neeg sai sai nrhiav thiab kho kev ua yuam kev thiab txo lub sijhawm. Optical modules ntsib sff-8472 tus qauv feem ntau muaj cov haujlwm ntawm cov ntaub ntawv kuaj thiab saib xyuas (DDM). Peb tuaj yeem siv txoj haujlwm no kom nkag siab txog qhov kev sib kis ntawm lub zog sib kis, txais lub zog, kev ua haujlwm kub, VCC, transmitter bias ceeb toom thiab lub tswb ceeb toom, kom txiav txim siab qhov txhaum ntawm qhov sib txuas hauv optical fiber txuas.

3. Xam qhov tseeb

Kev txheeb xyuas qhov tseeb yog txhawm rau tshuaj seb lub khoos phis tawm ntawm lub ntsej muag puas tuaj yeem ua haujlwm ib txwm nyob ntawm qhov chaw ua haujlwm xav tau los ntawm cov khoom siv tswv tsev, uas yog tib txoj kev los txiav txim siab qhov kev ua haujlwm ntawm cov khoos phis tawj. Feem ntau, qhov siab dua cov qib kho qhov muag tau ua tiav.

Muaj qee kis, yog tias qhov chaw ua haujlwm tsis zoo, kev ua haujlwm ntawm tus khoos phis tawm kho qhov muag yuav poob, lossis tseem ua rau kis tsis ua haujlwm ：

1.Cov voltage ntau tshaj li tus qauv ntsuas cov ntsuas hluav taws xob

2.Qhov lub zog tau txais yog siab dua lossis qis dua qhov kev cuam tshuam ntawm cov hluav taws xob kho qhov muag txais

3.Qhov ntsuas kub tshaj tus qauv tus nqi ntawm qhov khoos phis tawm kho qhov muag
