Okokuqala, ngaphambi kokwethula i-FTTR, sivele siqonde ukuthi iyini i-FTTx. I-FTTx isifinyezo se-"Fiber To The x" se-"fiber to x", lapho u-x engamele nje kuphela isayithi lapho ifayibha ifika khona, kodwa futhi ihlanganisa idivayisi yenethiwekhi yokubona efakwe kusayithi kanye nenkomba...

I-ONU: Igama eligcwele Iyunithi Yenethiwekhi ye-Optical, iyunithi yenethiwekhi yokubona, eyaziwa ngokuthi i-ONU, isebenzisa ubuchwepheshe be-PON passive optical fibre access, i-transmission medium ye-optical fibre, iyindlela enkulu yokufinyelela evamile yama-opharetha ezingcingo zomhlaba jikelele, enezinzuzo ze-cos ephansi. ...

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 “...

Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ubuchwepheshe be-FTTH (Fiber To The Home) busakazeka kabanzi, ne-China Telecom, i-China Mobile, i-China Unicom opharetha abathathu benethiwekhi yezokuxhumana sebeqedile ukuthunyelwa okuvuthiwe okukhulu, futhi njenge-ONU (optical). imodemu) isiyisidingo...

I-2.4G WiFi isebenza ngebhendi engu-2.4GHz enobubanzi befrikhwensi yokusebenza engu-2400~2483.5MHz. Izinga eliyinhloko elilandelwa yi-IEEE802.11b/g/n elibekwe i-IEEE (Association of Electrical and Electronics Engineers).Nazi lezi zindlela zokunquma ngokuningiliziwe: I-IEEE802.11 iyizinga elijwayelekile le-LAN engenantambo...

Isingeniso: I-ONU (Optical Network Unit) ihlukaniswe yaba iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi ye-passive optical, i-ONU iyisisetshenziswa esibulalayo somsebenzisi kunethiwekhi ye-optical, ebekwe ekugcineni komsebenzisi, esetshenziswa ne-OLT ukuze kuzuzwe i-Ethernet Layer 2, imisebenzi ye-Layer 3. , ukuhlinzeka abasebenzisi ngezwi, idatha ne...
