I-GPON Network Architecture
I-1) Isandulelo: Ngokuvela okusheshayo kwamabhizinisi ahlukahlukene, izimboni ezengeziwe ziyaqaphela ukuthi kuyadingeka ukugqekeza "ibhodlela" le-bandwidth ngokushesha ngangokunokwenzeka, futhi i-optical fiber iyindlela engcono kakhulu yokudlulisa. I-Optical fiber inezinzuzo ezimbili ngaphezu kwe ...Funda kabanzi - Ngu-Admin / 20 Jul 22 /0Amazwana
Ukufundwa okungavamile kolwazi lwemojuli ye-optical - hlola umyalezo wezibalo
Umsebenzi wokubuka izibalo zomlayezo: faka "isikhombikubona sombukiso" kumyalo ukuze ubuke amaphakethe angalungile ngaphakathi nangaphandle kwechweba, bese wenza izibalo zokunquma ukukhula kwevolumu, ukuze wahlulele inkinga yephutha. 1) Okokuqala, i-CEC, ifreyimu, namaphakethe wephutha we-throttles avela ku-t...Funda kabanzi - Ngu Admin / 19 Jul 22 /0Amazwana
Ukuxazulula izinkinga zokungajwayelekile kwe-DDM kumamojula abonakalayo
Uma isixhumi esibonakalayo semojula ye-optical efakiwe yehluleka ukusebenza kahle, ungakwazi ukuxazulula inkinga usebenzisa izindlela ezintathu ezilandelayo: 1)Hlola ulwazi lwe-Alarm lwemojula yokubona. Ngolwazi lwe-alamu, uma kunenkinga ngokwamukela, ngokuvamile kubangelwa...Funda kabanzi - Ngu Admin / 18 Jul 22 /0Amazwana
Ukuhlolwa kwamandla okubona
Inani lamandla okukhanya lizoba nomthelela onembile futhi osobala esignali ngesikhathi senqubo yokudlulisa, futhi lawa mandla okukhanya nawo alula ukuhlola. Leli nani lingahlolwa ngamandla okubona. Amandla okubona - sebenzisa imitha yamandla okubona ukuze uhlole ukuthi...Funda kabanzi - Ngu-Admin / 16 Jul 22 /0Amazwana
Ukuhlola amapharamitha amamojula optical
Ekusebenziseni ukusetshenziswa kwamamojula optical, akunakugwenywa ukubhekana nezinkinga ezihlukahlukene. Ukuze kuncishiswe ukwehluleka okuyinkinga, kodwa futhi nokuvikela ukuzinza kwemojula ye-optical ngokusebenzisa. Kuzoba khona imisebenzi ehlukene yokuthola amamojula abonakalayo. Imojuli ye-1X9 iyinhloko...Funda kabanzi - Ngu-Admin / 15 Jul 22 /0Amazwana
I-Optical Module Output Optical Power
Amandla okukhanya okukhiphayo (Output Power) abhekisela kumandla okukhanya okukhiphayo okumaphakathi omthombo wokukhanya ekugcineni kokudlulisela kwe-optical module, ebizwa nangokuthi amandla okukhanya okukhiphayo, okungaqondwa njengokushuba kokukhanya. Ifomula: P(dBm)=10Log(P/1mW) Iyunithi ingu-W noma mW noma i-dBm. (...Funda kabanzi
