      Izinkinga nezixazululo okuhlangatshezwane nazo ekufakweni nasekusetshenzisweni kwama-transceiver optical fiber

      Izinkinga nezisombululo okuhlangatshezwane nazo ekufakweni nasekusetshenzisweni kwama-transceivers efiber optical Isinyathelo sokuqala: qala ubone ukuthi ukukhanya kwenkomba ye-optical fibre transceiver noma imojula ye-optical kanye ne-twisted pair port ukukhanya kwe-port kuvuliwe? 1. Uma inkomba ye-optical port (FX) ye-A tr...

      Wazi kangakanani ngamamojula we-EPON OLT optical?

      I-EPON ubuchwepheshe be-PON obusekelwe ku-Ethernet. Isebenzisa ubuchwepheshe be-PON kungqimba olubonakalayo, iphrothokholi ye-Ethernet kungqimba lwesixhumanisi sedatha, ukufinyelela kwe-Ethernet kusetshenziswa i-PON topology, kanye nokufinyelela kwesevisi ngokugcwele kudatha, izwi, nevidiyo kusetshenziswa i-optical fiber. Incazelo yomkhiqizo we-EPON: I-EPON idlulisa futhi yamukele ...

      Iyini i-optical splitter futhi yiziphi izinkomba ezibalulekile zobuchwepheshe?

      I-optical splitter ingenye yezinsiza ezibalulekile zokungenzi lutho kusixhumanisi se-fiber optical, futhi idlala kakhulu indima yokuhlukanisa. Ngokuvamile isetshenziswa kutheminali yomugqa obonayo we-OLT kanye netheminali yenethiwekhi yokubona i-ONU yenethiwekhi ye-passive optical ukuze kubonakale ukuhlukana kwesignali yokubona. I-op...

      Iyini inethiwekhi yokufinyelela ifayibha?Ziyini izinzuzo ze-PON?

      Njengamanje, mayelana nobuchwepheshe benethiwekhi yokufinyelela kwe-fiber optical, ukufinyelela kwe-narrowband kancane kancane kuthathelwa indawo ukufinyelela kwe-broadband, futhi ekugcineni i-fiber home iyafinyelelwa. I-broadband optical fiber yenethiwekhi yokufinyelela iba yinto engenakugwemeka, futhi ubuchwepheshe be-PON buzoba indawo yobuchwepheshe ye ...

      Hlaziya ukuhlukaniswa nezici zamamojula we-PON optical

      Imojula ye-PON iyimojula ye-optical esebenza kahle kakhulu esetshenziswa kusistimu ye-PON, Ebizwa ngokuthi imojula ye-PON,Thobela isivumelwano se-ITU-T G.984.2 esijwayelekile kanye nemithombo eminingi (MSA),Isebenzisa ubude obuhlukene ukuthumela nokwamukela amasignali phakathi kwe-OLT (Optical Line Terminal) kanye ne-ONT (Optical Network Terminal). Ty...

      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...
