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...Funda kabanzi - Ngomphathi / 28 Apr 20 /0Amazwana
OLT, ONU, ODN
I-OLT iyitheminali ye-optical line, i-ONU iyiyunithi yenethiwekhi ye-optical (ONU), zonke ziyimishini yokuxhuma inethiwekhi yokudlulisa amehlo. 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)...Funda kabanzi - Ngomlawuli / 24 Apr 20 /0Amazwana

Ulwazi oluningiliziwe lokuhlinzekwa kwamandla kwe-POE
Ngokuthuthuka okusheshayo kwezingcingo ze-IP, ama-AP wephoyinti lokufinyelela le-LAN engenantambo, nokuqapha kwenethiwekhi eminyakeni yamuva, umkhawulo wobuchwepheshe uya ngokuya ukhuphuka, futhi ukwesekwa kobuchwepheshe okuhlinzekwa abakhiqizi kuya ngokuya kuhlanganisa futhi kuhlelekile. 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
