    Sharaxaada aasaasiga ah ee khariidadda indhaha iftiinka II

    Waqtiga boostada: Agoosto-27-2024

    Tafsiir qoto dheer oo jitter ah
    Haddii heerka xogta nidaamka la kordhiyo, baaxadda jitter ee lagu qiyaasay dhowr ilbiriqsi gudahood waxay ahaan doontaa qiyaas ahaan isku mid, laakiin marka lagu qiyaaso qayb ka mid ah wakhtiga xoogaa, waxay u kordhin doontaa si la mid ah heerka xogta, taasoo keentay xoogaa yar. khaladaadka. Sidaa darteed, jitter-ka la xidhiidha waa in la yareeyaa sida ugu macquulsan ee nidaamka si loo hagaajiyo waxqabadka nidaamka guud.

    Jitter wuxuu qeexayaa isbedbedelka tooska ah ee calaamadda, taas oo ah, leexashada muddada-gaaban ee calaamadda ka timid meesha ay ku habboon tahay waqtigeeda waqti gaar ah.

    1. Fasiraadda meelaha isgoysyada

    Saamiga isdhaafka ee calaamadda caadiga ah ee guud waa 50%, taas oo macnaheedu yahay in calaamadda "1" iyo "0" ay mid kastaa ka dhigan tahay kala bar heerka. Si loo cabbiro saamiga isku xidhka, isticmaal habka tirakoobka ee shaxanka lagu muujiyey. Heerka iskutallaabtu waa celceliska la xisaabiyay iyada oo loo eegayo daaqadda dhexe ee tirakoobka toosan ee barta istallaabta, isla'egta saamigeeduna waa sidan soo socota (halka heerka 1 iyo 0 uu yahay celceliska qiimaha 20% ee bartamaha khariidadda isha. Taasi waa, beddelka 40% ilaa 60%

    2.Saamaynta

    Awoodda calaamadda 1 ama 0 ee gudbinta cufka waxay ku kala duwan tahay saamiga meelaha laga gudbo. Sida ku cad shaxanka, jaantuska bidix waa khariidad isha oo leh xiriiro isdhaafsi oo kala duwan, oo u dhiganta calaamadaha garaaca wadnaha ee 1 iyo 0 ee midig. Isla mar ahaantaana, waxaan sidoo kale fahmi karnaa xiriirka ka dhexeeya ballaca wakhtiga calaamadaha garaaca wadnaha ee kala duwan iyo saamiga iskutallaab ee garaafka.

    3.soo koob

    Calaamadaha guud, celceliska calaamadaha la qaybiyey ee 1 iyo 0 ayaa ah kuwa ugu badan. Guud ahaan waxaa loo baahan yahay in saamiga istaroogga sawirka isha uu yahay 50%, taas oo ah, isla dhererka garaaca garaaca garaaca 1 iyo 0 ayaa loo isticmaalaa heerka caadiga ah si loo xaqiijiyo cabbirrada ku habboon. Sidaa darteed, falanqaynta baaxadda baaxadda qaraabo ee ay sababtay leexinta heerarka kala duwan ee calaamadaha 1 iyo 0 ayaa si wax ku ool ah loo cabbiri karaa iyadoo loo eegayo qaybinta xiriirka saamiga isdhaafka isha. Tusaale ahaan, haddii saamiga isdhaafka isha uu aad u weyn yahay, taas oo ah, calaamado badan oo heer 1 ah ayaa la kala qaadaa, qaladka signalka, gaashaanka iyo xadkeeda ayaa la xaqiijin doonaa iyadoo loo eegayo xiriirka saamigaan isdhaafsiga ah. Saamiga istaroogga isha aad ayuu u yar yahay, taas oo ah, gudbinta calaamadaha heerka 0 aad u badan, guud ahaan si sahlan in la keeno calaamada qaataha ma fududa in la soo saaro inta jeer ee ay ka soo baxdo, taasoo keentay in ay ku guuldareysato in ay isku xirto, taasoo keentay luminta isku xirnaanta. Waxay u dhigantaa mowjad labajibbaaran, taasoo keentay is-waafajin la'aanta soo noqnoqda, iyo in ka yar 50% saamiga mawjadda labajibbaaran.

    Kor ku xusan waa Shenzhen HDV Phoeletron Technology Ltd. si ay u keenaan macaamiisha ku saabsan "Maabka indhaha indhaha sharaxaad aasaasiga ah II" article hordhaca ah, iyo shirkadeena waa wax soo saarka gaarka ah ee saarayaasha network indhaha, alaabta ku lug yihiinONUtaxane (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Taxanaha moduleka indhaha (Module fiber optical/Module fiber indhaha ee Ethernet / moduleka indhaha ee SFP),OLT-pon-modules/">OLTtaxane (OLTqalab /OLT beddelo/ Bisadda indhahaOLT), iwm, waxaa jira tilmaamo kala duwan oo alaabta isgaarsiinta ah oo loogu talagalay baahida xaaladaha kala duwan ee taageerada shabakada, ku soo dhawow inaad la tashato.
