Optical fiber transceiver yog qhov ua kom raug nqi thiab hloov kho tau yooj yim.
Kev siv ntau tshaj plaws yog los hloov cov hluav taws xob cov hluav taws xob hauv kev sib hloov ntawm tus khub hloov mus ua lub cim hluav taws xob. Nws feem ntau siv hauv Ethernet tooj liab tooj liab uas tsis tuaj yeem npog thiab cov khoom siv hluav taws xob zoo yuav tsum siv los txuas qhov kev sib kis deb.
Hauv qhov tseeb network ib puag ncig, nws tseem ua txoj haujlwm tseem ceeb hauv kev pabcuam los txuas cov mais kawg ntawm cov kab hluav taws xob optical mus rau cheeb tsam nroog thiab network sab nrauv. Lub pob nyem yog cov cuab yeej siv network los xa cov ntawv hluav taws xob (kho qhov muag).
Nws yog lub luag haujlwm tseem ceeb hauv kev sib txuas lus sib txuas ntawm cov khoom siv sib txuas hauv lub xov tooj (xws li khoos phis tawj, tshuab luam ntawv, khoos phis tawm, thiab lwm yam). Nws feem ntau txuas nrog rau router kom koj tuaj yeem hla optical Cat nkag mus rau lub network.
Transceiver kho qhov muag vs hloov: thaum xaiv qhov twg?
Ob lub tshuab hluav taws xob txuas thiab cov pob hluav taws xob tuaj yeem siv los txuas cov tooj liab kab hluav taws xob thiab cov cuab yeej hluav taws xob optical fiber ntau. Yog li, thaum twg xaiv fiber ntau optic transceivers lossis network hloov pauv hauv Ethernet? Qhov no yuav qhia ntxiv rau koj hauv qab no.
Cov khoom siv hluav taws xob fiber ntau feem ntau yog siv thaum tsis tau them cov xaum hluav taws xob Ethernet thiab cov hlua hluav taws xob fiberers yuav tsum siv cov khoom sib kis tau ntev li qhov peev nyiaj. Lawv tuaj yeem siv rau kev tsim kho cov cheeb tsam hauv nroog thiab cov nroog sib txuas hauv nroog, xws li cov tuam txhab kev lag luam thiab cov xaib rov qab lub nroog.
Lub network hloov pauv muaj ntau lub ports rau cov khoom sib txawv (xws li computer thiab printers) los sib txuas lus hauv LAN. Hauv lwm lo lus, lub network hloov yog ib qho khoom siv hloov tau uas yuav muab tau yooj yim ntxiv rau hauv lub network kom nthuav tawm cov peev xwm hauv lub network. Ib qho ntxiv, nws tseem tuaj yeem tiv thaiv kev thauj mus los ntawm ob lub khoom siv los ntawm kev cuam tshuam koj lwm cov khoom siv hauv tib lub network, tso cai rau koj los tswj lub network tau yooj yim.
Cov khoom siv hluav taws xob fiber ntau thiab cov hloov xaib kuj tseem tuaj yeem ua haujlwm hauv tib lub network. Piv txwv li, thaum lub network hloov tsuas muaj cov chaw nres nkoj hluav taws xob, tab sis yuav tsum xa tawm ntau dua 100 metres, nws yog qhov yuav tsum tau siv cov hluav taws xob xa hluav taws xob xa cov hluav taws xob xa mus rau cov cim hluav taws xob kom ua tiav kev sib kis tau.
