Kungenzeka ukuthi awazi ukuthi iyini i-“PON” (imvamisa ifundeka ngokuthi “pang”), kodwa kufanele ukuthi uzwile “ngefayibha eya ekhaya”.
Ungase ungazi ukuthi iyini i-“ONU” (imvamisa ifundeka ngokuthi “ONU”), kodwa uma uvula ibhokisi likagesi elibuthakathaka ekhaya lakho, kufanele ubone “ibhokisi elincane” elinefiber optical.Leli “bhokisi elincane” yi-ONU (Optical Network Unit, optical network unit), eyaziwa ngokuthi “ONU”.I-protagonist yanamuhla —— “PON” (Passive Optical Network, passive Optical network), iwukhiye wokufinyelela i-optical fibre, iwubuchwepheshe bokudlulisa “ikhilomitha lokugcina” i-optical fiber phakathi kwenethiwekhi nabasebenzisi.
Wisigqoko yi-PON?
Ifayibha ye-optical yasendlini ngayinye, exhunywe ngemuva kwenethiwekhi enkulu, masilandele i-optical fiber, silandele umfudlana, sihlole ndawonye.I-fiber optical exhunywe ku-ONU ivela ku-splitter kugesi obuthakathaka kahle / umhubhe, ongahlukanisa isignali ye-optical kumashaneli amaningi ngesilinganiso esithile.Isignali yokubona engena kusihlukanisi se-optical ivela kutheminali yomugqa we-optical OLT (Optical Line Terminal).I-OLT, i-ONU, naphakathi “kwamashaneli okudlulisela” amabili i-ODN (Optical Distribution Network, optical distribution network) bakha inethiwekhi ye-PON.Phakathi:
I-OLT iyidivayisi eseceleni kuka-opharetha enesibopho sokunikeza idatha kunethiwekhi yebhizinisi yezinga eliphezulu.
I-ONU iyidivayisi eseceleni komsebenzisi enesibopho sokwamukela idatha ethunyelwe i-OLT futhi ngokuqondile kumsebenzisi.
Singathola ukuqonda okufushane kwezakhiwo zenethiwekhi ye-PON ngokusho kwesibalo esingezansi.
I-Shenzhen HDV Photoelectron Technology Ltd. ingumkhiqizi wemishini ye-ONU ochwepheshe futhi i-ONU yokuxhumana ehlakaniphile nomkhiqizi wamamojula, inkampani yethu njengamanje ithengisa izinhlobo ezahlukene zemishini yokuxhumana ephezulu naphansi, njenge: I-Fiber media converter, switch ye-Ethernet, imishini ye-OLT, imishini ye-ONU kanye njalonjalo.Uma ufuna ukwazi kabanzi ngobuchwepheshe bezokuxhumana, wamukelekile ukuthi usithinte noma kunini.
