Kev soj ntsuam digital kuaj mob (tseem hu ua digital kho qhov muag) muab tiag tiag {{ Koj yuav tsum tau siv nws - Cov ntaub ntawv no ua rau kev twv xyuas kev twv xyuas, txheeb xyuas kev hloov pauv kev ua haujlwm ua ntej lawv ua tsis tiav.
Tuaj yeem sib xyaw hom transceiver ua teeb meem?
Feem ntau tsis muaj, ntev li ntev tau cov lus qhia tshwj xeeb (wavelength, cov ntaub ntawv tus nqi, fiber ntau hom). Tus qauv Optics yog tus muag khoom - negural. However, verify that both transceivers communicate at the same speed-some vendors' auto-negotiation implementations don't interoperate perfectly. Thaum nyob rau hauv kev ua xyem xyav, sim cov kev sib xyaw ua ke ua ke ua ntej xa tawm.
Pheej Yig Suav Transceires kom ruaj khov?
Lo lus nug no nthuav tawm ib qho kev tsis paub tseeb -|cov chaw tsim khoom feem ntau ntawm txhua transceed los ntawm Cisco, Juniper, Arista, thiab lwm tus. Cov lus nug yog tiag tiag txog kev tswj kom zoo thiab kev sim nruj. Recutable thib peb - Cov Khoom Siv Tog Zaum (FS.com. Zam tsis txhob cov neeg muag khoom ntawm Amazon / eBay nrog pes tsawg cov ntaub ntawv teev thiab tsis muaj kev sim cov ntaub ntawv.
Hauv qab kab
Transceivers yog qhov pom tsis tau cov cuab yeej ua kom muaj kev sib txuas tshiab. Txhua qhov video hu, huab upload, thiab streaming ntu yog nyob ntawm cov ntaub ntawv uas muaj hluav taws xob rov qab mus rau theem hluav taws xob rov qab los ntawm cov khoom siv hluav taws xob rov qab los thaum muaj kev sib kis.
Kev ua lag luam qhia zaj dab neeg ntawm cov ntaub ntawv cov ntaub ntawv nthuav dav: los ntawm $ 13,6 lab daus las, cov ntaub ntawv chaw nthuav dav, thiab bandwidth {{5: {5:} Cov neeg tshaib plab.
Rau cov kws tshaj lij network, txoj kev vam meej los rau kev sib txuam nrog koj cov kev xav tau: kev deb, cov ntaub ntawv, ib puag ncig cov xwm txheej, thiab pob nyiaj. Overspecifying nyiaj. Underspifyees fas.
Yav tom ntej cov ntsiab lus mus rau sai sai, kev noj hluav taws xob qis, thiab kev sib koom ua ke nrog kev sib xyaw ua si silicon. Tab sis qhov tseem ceeb txoj haujlwm tseem tsis hloov pauv: tsiv koj cov ntaub ntawv ntseeg tau los ntawm point B, ib lub teeb mem tes lossis xov tooj cua ntawm ib lub sijhawm.
Kev nkag siab Transceasivers tsis yog kev paub txog kev paub - Nws tau nkag siab cov cuab yeej uas txuas rau peb lub ntiaj teb.
