Ujongano lweFibre-optic yeemodyuli ezibonakalayo
Oku kubhekiselele kujongano lwemodyuli ye-optical kwintambo yefiber optic patch, enokuthi idityaniswe ngemowudi enye okanye intambo yefiber optic yemultimode. Oku kulandelayo kukuhlalutya oku ngokweendlela ezahlukeneyo zojongano. Okwangoku, olona nxibelelwano luphambili kwimarike zezi: MPO, LC, S...Funda ngokugqithisileyo - Ngu Admin / 13 Jul 22 /0Amagqabantshintshi
Iklasi yeLaser yeemodyuli ze-SFP
Okwangoku, kukho iilaser zeFBG, FB kunye neDFB, Phakathi kwazo, ezona lasers zisetyenziswa ngokuqhelekileyo yiFP kunye neDFB. FBG: IFayibha Bragg Grating. I-FP: I-Fabry-Perot, i-Fabry-Perot ye-Laser Diode i-DFB: i-Fabry Feedback Laser, i-Feedback Feedback ye-Laser Diode ye-FB esetyenziswa ngokuqhelekileyo kunye ne-DFB. I-DFB ihlala...Funda ngokugqithisileyo - Ngu Admin / 12 Jul 22 /0Amagqabantshintshi
Yintoni ebangela iLahleko kuthumelo lwefiber optics?
Kweli nqaku ndiza kuthetha malunga nokuba yintoni ebangela ilahleko kuthumelo lwefiber optics. Masifunde… Isizathu sokuba kutheni i-optical fiber ithathe indawo yosasazo oluphakathi kunye nomgama omde lweentambo zothungelwano kungenxa yokuba usasazo lwefiber optical linelahleko ephantsi, kwaye ilahleko yalo yahlulwe kakhulu koku kulandelayo:...Funda ngokugqithisileyo - Ngu Admin / 11 Jul 22 /0Amagqabantshintshi
Iiparamitha ezintathu eziphambili zeemodyuli ze-optical
(i) Ubude bombindi bobude obusebenzayo bemodyuli ye-optical eneneni luluhlu, kodwa kuya kubakho umahluko ocacileyo phakathi kwemowudi enye kunye nemowudi eninzi. Emva koko eli binzana lithiywa ngokubanzi ngokona bude buphakathi. Iyunithi yobude obuphakathi yinanometer (nm), ...Funda ngokugqithisileyo - Ngu Admin / 08 Jul 22 /0Amagqabantshintshi
Imodyuli ye-PON ye-Optical kunye neModyuli yeMveli yeMveli
Ngokohlelo oluhlukeneyo lwexesha lophuhliso: Iimodyuli ze-Optical zihlulwe zibe ziindidi ezimbini: iimodyuli ze-PON kunye neemodyuli ze-optical zendabuko. Xa usebenzisa iimodyuli zendabuko ye-optical: Imodyuli yokuhanjiswa kwesignali ye-optical point-to-point (P2P: enye yokudluliselwa kwenye), imodyuli ...Funda ngokugqithisileyo - Ngu Admin / 07 Jul 22 /0Amagqabantshintshi
Ukuthelekiswa kweemodyuli ze-GPON kunye ne-EPON
Molo, Wamkelekile. Masifunde uthelekiso phakathi kweemodyuli ze-GPON kunye ne-EPON kwinkcazo elula. Imodyuli yokubona yeGPON inokusebenza okungcono kunemodyuli ye-EPON yokubona. Ngokwesantya, i-downlink ingcono kune-EPON; Ngokweshishini, i-GPON igubungela uluhlu olubanzi; Ukusuka kuthumelo...Funda ngokugqithisileyo
