Ngophuhliso lwenkqubo yonxibelelwano lwe-optical kunye nomgama omde, umthamo omkhulu kunye nesantya esiphezulu, ngakumbi xa isantya se-wave wave sivela kwi-40g ukuya kwi-100g okanye nakwi-super 100g, i-chromatic dispersion, i-nonlinear effect, i-polarization mode dispersion kunye nezinye iziphumo zokuhambisa kwi-op. .

isandulela FTTH sithetha ifayibha ekhaya kwaye ngokuthe ngqo kwiitheminali zabasebenzisi. Le ikwayitekhnoloji ebesiyisukela kwaye siyiphonononga ngaphezulu kweminyaka engama-20. Ngenxa yokuphumelela okuqhubekayo kwiindleko, iteknoloji, imfuno kunye nokunye, obu bugcisa bukhuthazwe ngokubanzi kwaye buphuhliswe. Kumaphephandaba...

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...

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...

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...

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...
