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...

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. (...

Okulandelayo ukuhlaziya lokhu ngokusho kokusebenzelana okuhlukene. Njengamanje, izixhumanisi ezibonakalayo eziyinhloko emakethe yilezi: MPO, LC, S... Funda kabanzi Ngu-Admin / 13 Jul 22 /0Amazwana Ikilasi le-Laser lamamojula we-SFP Njengamanje, kukhona amalaser e-FBG, FB kanye ne-DFB, Phakathi kwawo, amalaser asetshenziswa kakhulu yi-FP ne-DFB. I-FBG: I-Fiber Bragg Grating. I-FP: I-Fabry-Perot, i-Fabry-Perot I-Laser Diode DFB: I-Laser Yempendulo Esabalalisiwe, Impendulo Esabalalisiwe Ye-Laser Diode Ye-FB evame ukusetshenziswa kakhulu ne-DFB. I-DFB...
