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 - Ngu Admin / 06 Jul 22 /0Amagqabantshintshi
Ukuhlelwa kweeModyuli zePON
Molweni Abafundi, Ngezantsi ezantsi siza kuthetha malunga noHlelo lweeModyuli zePON kwaye siya kuzama ukukuchaza ngokulula. (1) Imodyuli ye-OLT ye-optical kunye ne-ONU imodyuli ye-optical: Ngokokwahlulahlulo oluhlukeneyo lwezixhobo ze-plug-in kukho iindidi ezimbini zeemodyuli ze-PON optical: imodyuli ye-OLT ye-optical (le ...Funda ngokugqithisileyo - Ngu Admin / 05 Jul 22 /0Amagqabantshintshi
Ukuhlelwa kweeModyuli ze-Optical
Umahluko phakathi kwe-SFF, i-SFP, i-SFP + kunye ne-XFP iimodyuli ze-optical ezihlelwe ngokweentlobo ezahlukeneyo zokupakisha, iimodyuli ze-PON ezibonakalayo zingahlulwa zibe ziintlobo ezilandelayo; Imodyuli ye-SFF ye-optical: Le modyuli incinci ngobukhulu, ilungisiwe ngokubanzi, ithengiswa kwi-PCBA esisigxina, kwaye ayikwazi ukukhutshwa.
