Ulwazi

Okokuqala, ngaphambi kokwazisa i-FTTR, siyaqonda nje ukuba yintoni iFTTx. I-FTTx sisishunqulelo sika "Ifayibha ukuya ku-x" ye "ifayibha ukuya ku-x", apho u-x engameli kuphela indawo apho ifayibha ifika khona, kodwa ikwabandakanya isixhobo sothungelwano olubonayo olufakwe kwisiza kunye nokuchonga...

I-ONU: Igama elipheleleyo iYunithi yeNethiwekhi ye-Optical, iyunithi yenethiwekhi ye-optical, eyaziwa ngokuba yi-ONU, isebenzisa i-PON passive optical fibre access technology, i-transmission medium ye-fiber optical, yindlela yokufikelela kwizinga elikhulu labaqhubi be-telecom yehlabathi, kunye neenzuzo ze-cos ephantsi. ...

Usenokungayazi ukuba yintoni na i-"PON" (ehlala ifundwa njenge "pang"), kodwa kufuneka ukuba uve nge "fiber ekhaya". Usenokungazi ukuba yintoni i-“ONU” (idla ngokufundeka ngokuthi “ONU“), kodwa xa uvula ibhokisi yombane ebuthathaka kwikhaya lakho, kufuneka ubone “...

Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe, iteknoloji ye-FTTH (iFiber ukuya kwiKhaya) isasazeka ngokubanzi, kunye ne-China Telecom, i-China Mobile, i-China Unicom abaqhubi abathathu benethiwekhi yonxibelelwano baye bagqiba ukuhanjiswa okukhulu okuvuthiweyo, kwaye njenge-ONU (optical). modem) sele iyimfuneko...

I-2.4G WiFi isebenza kwibhendi ye-2.4GHz kunye noluhlu lwefrikhwensi yokusebenza ye-2400 ~ 2483.5MHz. Umgangatho ongundoqo olandelwayo ngumgangatho we-IEEE802.11b/g/n omiselwe yi-IEEE (I-Association of Electrical and Electronics Engineers) .Nazi ezi nkqubo ngokweenkcukacha: IEEE802.11 ngumgangatho woqobo weLAN yeLAN...

Intshayelelo: I-ONU (i-Optical Network Unit) yahlulwe yaba yiyunithi esebenzayo yenethiwekhi ye-optical network kunye neyunithi yenethiwekhi ye-passive optical, i-ONU sisixhobo sokuphela komsebenzisi kwinethiwekhi ye-optical, ibekwe ekupheleni komsebenzisi, isetyenziswe kunye ne-OLT ukufezekisa i-Ethernet Layer 2, i-Layer 3 imisebenzi. , ukunika abasebenzisi ilizwi, idatha kunye...
