I-EPON kunye ne-GPON zineenzuzo zazo. Ukusuka kwisalathiso sokusebenza, i-GPON iphezulu kune-EPON, kodwa i-EPON ineenzuzo zexesha kunye neendleko. I-GPON iyabamba. Ukujonga phambili kwimakethi yokufikelela kwibroadband yexesha elizayo, isenokungabi ngubani othatha indawo kabani, kufuneka ihlale ihleli kunye kwaye iyancedisana. Yeqela...

I-OLT yi-terminal yomgca we-optical, i-ONU yiyunithi yenethiwekhi ye-optical network (ONU), zonke zizixhobo zoqhagamshelwano zothungelwano lwe-optical transmission. Zimbini iimodyuli eziyimfuneko kwi-PON: I-PON (Inethiwekhi ye-Passive Optical: inethiwekhi ye-optical network). I-PON (uthungelwano lwe-optical network) ibhekisa ku (inethiwekhi yosasazo olubonakalayo)...

Ngophuhliso olukhawulezayo lweefowuni ze-IP, i-wireless LAN ukufikelela kwindawo ye-APs, kunye nokubeka iliso kwinethiwekhi kwiminyaka yamuva nje, umda wobugcisa uya uphezulu kwaye uphezulu, kunye nenkxaso yobugcisa ebonelelwa ngabavelisi iya iba ngokubanzi kwaye icwangciswe. Phakathi kwezobuchwephesha...

Ifiber yemowudi enye (SingleModeFiber) yifiber optical enokuhambisa imowudi enye kuphela kubude obuxeliweyo. Undoqo weglasi ubhityile kakhulu (undoqo wedayamitha yi-9 okanye 10μm). Ngoko ke, i-inter-mode yokusasazwa kwayo incinci kakhulu, ilungele unxibelelwano olukude Nangona kunjalo, kukho i-al...

Ngoku kunye nedatha yedatha ye-10G imodyuli ye-optical | Imodyuli ye-40G ye-optical | Imodyuli ye-100G ye-optical iyindlela yophuhliso jikelele kwiimarike, phantsi kolu hlobo lokukhula ngokukhawuleza, imodyuli ye-10G yehlabathi jikelele | Imodyuli ye-40G ye-optical | Ingeniso yemodyuli ye-100G ikwi-optical iyonke Imarike yemodyuli iya kuphendula...

Intshayelelo: Ngophuhliso lwenzululwazi nobuchwepheshe, isantya solwazi lwasezidolophini siyakhula, kwaye iimfuno zobuchwepheshe bonxibelelwano ziya zisiba phezulu ngokunyuka. Iintsinga ze-Optical ziye zathandwa ngakumbi kunxibelelwano ngenxa yeenzuzo zazo zokuhanjiswa ngokukhawuleza ...
