Ngomphathi / 30 Apr 20 /0Amazwana Ukuhlaziywa okuningiliziwe kwe-EPON vs GPON yikuphi okungcono? I-EPON ne-GPON banokufaneleka kwabo. Kusukela kunkomba yokusebenza, i-GPON iphakeme kune-EPON, kodwa i-EPON inezinzuzo zesikhathi nezindleko. I-GPON iyabamba. Uma sibheke phambili emakethe yokufinyelela ye-broadband yesikhathi esizayo, kungase kungabi ukuthi ubani othatha indawo kabani, kufanele kuhlalisane futhi kuhambisane. Okwe-bandw...

Kungamamojula amabili adingekayo ku-PON: I-PON (Inethiwekhi ye-Passive Optical: inethiwekhi yokubona engenzi lutho). I-PON (inethiwekhi ye-passive optical network) isho (inethiwekhi yokusabalalisa okubonakalayo)...

Phakathi kwezobuchwepheshe... Funda kabanzi Ngomlawuli / 17 Apr 20 /0Amazwana Iyini i-fiber yemodi eyodwa? Yiziphi izinzuzo nezingozi? Ifayibha yemodi eyodwa (SingleModeFiber) iyifayibha yokubona engadlulisa imodi eyodwa kuphela ngobude obucacisiwe. Umongo wengilazi ophakathi mncane kakhulu (ububanzi bomnyombo ngokuvamile bungu-9 noma 10μm). Ngakho-ke, ukuhlakazeka kwayo kwe-inter-mode kuncane kakhulu, kulungele ukuxhumana okukude Nokho, kukhona al...

Funda kabanzi Ngomlawuli / 10 Apr 20 /0Amazwana Uyini umehluko phakathi kwamamojula we-fiber optic nama-fiber optic transceivers? Isandulelo: Ngokuthuthuka kwesayensi nobuchwepheshe, isivinini sokwaziswa kwedolobha siyakhula, futhi izidingo zobuchwepheshe bezokuxhumana ziya ngokuya ziba phezulu. Imicu ye-Optical isidume kakhulu ekuxhumaneni ngenxa yezinzuzo zayo zokudluliswa okusheshayo ... Funda kabanzi << < Edlule31323334353637Okulandelayo >>> Ikhasi 34/47
