Ii-transceivers ze-fiber optical zisetyenziswa ngokubanzi kwiindawo zenethiwekhi zangempela apho iintambo ze-Ethernet azikwazi ukugqunywa kwaye iifayili ze-optical kufuneka zisetyenziswe ukwandisa umgama wokuhambisa. Kwangaxeshanye, baye badlala indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber optical ...

Sisoloko sisiva ngokutshintsha kwefiber optic kunye neetransceivers zefiber optic. Phakathi kwazo, iiswitshi zefiber optic zizixhobo zokuhanjiswa kwenethiwekhi ezinesantya esiphezulu, ezikwabizwa ngokuba zizitshixo zefayibha kunye nokutshintsha kweSAN. Xa kuthelekiswa nokutshintsha okuqhelekileyo, basebenzisa iintambo zefiber optic njengesixhobo sokuhambisa...

Ngaphambi kokuba siqonde utshintsho lwe-PoE, kufuneka siqale siqonde ukuba yintoni i-PoE. I-PoE lubonelelo lwamandla ngaphezulu kwetekhnoloji ye-Ethernet. Yindlela yokubonelela ngokude amandla kwizixhobo zenethiwekhi ezixhunyiwe (ezifana ne-Wireless LAN AP, i-IP Phone, iBluetooth AP, ikhamera ye-IP, njl.) kwintambo yedatha ye-Ethernet esemgangathweni, el...

I-1.1 Imodyuli yomsebenzi osisiseko I-transceiver ye-fiber optical iquka iimodyuli ezintathu ezisisiseko ezisebenzayo: i-photoelectric media conversion chip, i-interface ye-optical signal (imodyuli edibeneyo ye-transceiver edibeneyo) kunye ne-interface yesignali yombane (RJ45). Ukuba ixhotyiswe ngemisebenzi yolawulo lwenethiwekhi, ikwabandakanya...

I-Optical fiber fusion splicing process Iindlela zokudityaniswa kwefiber Optical zinokwahlulwa zibe ziindidi ezimbini: enye yindlela yoqhagamshelo esisigxina engenako ukuqhawuka kwaye idityaniswe xa sele idityanisiwe, kwaye enye yindlela yoqhagamshelo enokudityaniswa ngokuphindaphindiweyo kwaye idityaniswe...

Ukutshintsha kwePoE sisitshixo esixhasa unikezelo lwamandla kwintambo yenethiwekhi. Xa kuthelekiswa nokutshintsha okuqhelekileyo, i-terminal yokufumana amandla (efana ne-AP, ikhamera yedijithali, njl.) Akufuneki ukuba ifakwe kwintambo yombane, kwaye ukuthembeka kwenethiwekhi yonke kuphezulu. Umahluko phakathi kweP...
