GPON Network Architecture
I-1) Intshayelelo: Ngokuvela ngokukhawuleza kwamashishini ahlukeneyo, amashishini amaninzi nangaphezulu ayaqonda ukuba kuyimfuneko ukukrazula "i-bottleneck" ye-bandwidth ngokukhawuleza, kwaye i-fiber optical iyona ndlela ehamba phambili yokuhambisa. Ifiber ye-Optical ineengenelo ezimbini ngaphezulu kwe...Funda ngokugqithisileyo - Ngu Admin / 20 Jul 22 /0Amagqabantshintshi
Ukufundwa okungaqhelekanga kolwazi lwemodyuli yokubona - khangela umyalezo weStatistics
Umsebenzi wokujonga izibalo zomyalezo: ngenisa "ujongano lokubonisa" kumyalelo wokujonga iipakethe ezingalunganga ngaphakathi nangaphandle kwezibuko, kwaye emva koko wenze izibalo ukumisela ukukhula komthamo, ukugweba ingxaki yempazamo. 1) Okokuqala, i-CEC, isakhelo, kunye neepakethe zempazamo ze-throttles zivela kwi-t...Funda ngokugqithisileyo - Ngu Admin / 19 Jul 22 /0Amagqabantshintshi
Ukulungisa iingxaki kwi-DDM engaqhelekanga kwiimodyuli zamehlo
Xa ujongano lwemodyuli efakiweyo yokubona isilele ukusebenza kakuhle, ungalungisa ingxaki ngokwezi ndlela zintathu zilandelayo: 1) Jonga ulwazi lweAlarm yemodyuli yokubona. Ngolwazi lwe-alam, ukuba kukho ingxaki ngolwamkelo, ngokuqhelekileyo lubangelwa...Funda ngokugqithisileyo - Ngu Admin / 18 Jul 22 /0Amagqabantshintshi
Uvavanyo lwamandla okukhanya
Ixabiso lamandla okukhanya liya kuba nefuthe elibonakalayo kunye necacileyo kwisignali ngexesha lokuhanjiswa kwenkqubo, kwaye le mandla optical nayo ilula ukuvavanya. Eli xabiso linokuvavanywa ngamandla optical. Amandla okukhanya - sebenzisa imitha yamandla okukhanya ukuvavanya ukuba...Funda ngokugqithisileyo - NguMlawuli / 16 Jul 22 /0Amagqabantshintshi
Ukuvavanya iiparamitha zeemodyuli ze-optical
Ekusebenziseni ukusetyenziswa kweemodyuli ze-optical, akunakuphepheka ukuhlangabezana neengxaki ezahlukeneyo. Ukuze kuncitshiswe ingxaki yokungaphumeleli, kodwa nokukhusela uzinzo lwemodyuli ye-optical ngokusebenzisa. Kuya kubakho imisebenzi yobhaqo eyahlukeneyo yeemodyuli ezibonakalayo. Imodyuli ye-1X9 yeyona nto iphambili...Funda ngokugqithisileyo - Ngu Admin / 15 Jul 22 /0Amagqabantshintshi
IModyuli ye-Optical Output yamandla okukhanya
Imveliso ye-optical power (Amandla okuPhuma) ibhekiselele kumyinge wemveliso ye-optical power yomthombo wokukhanya ekupheleni kokuthumela imodyuli ye-optical, ekwabizwa ngokuba yi-output optical power, enokuqondwa njengobunzulu bokukhanya. Ifomula: P(dBm)=10Log(P/1mW) Iyunithi nguW okanye mW okanye dBm. (...Funda ngokugqithisileyo
