Molweni Abafundi, Ngezantsi ezantsi siza kuthetha malunga noHlelo lweeModyuli zePON kwaye siya kuzama ukukuchaza ngokulula. (1) Imodyuli ye-OLT ye-optical kunye ne-ONU imodyuli ye-optical: Ngokokwahlulahlulo oluhlukeneyo lwezixhobo ze-plug-in kukho iindidi ezimbini zeemodyuli ze-PON optical: imodyuli ye-OLT ye-optical (le ...

Umahluko phakathi kwe-SFF, i-SFP, i-SFP + kunye ne-XFP iimodyuli ze-optical ezihlelwe ngokweentlobo ezahlukeneyo zokupakisha, iimodyuli ze-PON ezibonakalayo zingahlulwa zibe ziintlobo ezilandelayo; Imodyuli ye-SFF ye-optical: Le modyuli incinci ngobukhulu, ilungisiwe ngokubanzi, ithengiswa kwi-PCBA esisigxina, kwaye ayikwazi ukukhutshwa. Th...

Imodyuli ye-PON ye-optical module, ngamanye amaxesha ebizwa ngokuba yi-PON imodyuli, imodyuli ephezulu yokusebenza esetyenziswa kwiinkqubo ze-PON (i-passive optical network). Isebenzisa ubude bamaza ahlukeneyo ukuhambisa kunye nokufumana iimpawu phakathi kwe-OLT (i-Optical Line Terminal) kunye ne-ONT (i-Optical Network Terminal) ngokuhambelana ...

"VPN" i-VPN iteknoloji yokufikelela kude. Ngamagama alula, kukusebenzisa ikhonkco lothungelwano lukawonke-wonke (elidla ngokuba yi-Intanethi) ukuseta inethiwekhi yabucala. Ngokomzekelo, ngolunye usuku umphathi uthumela uhambo lwezoshishino kwilizwe, kwaye ufuna ukufikelela kwinethiwekhi yangaphakathi yeyunithi kwintsimi. ...

Uguqulelo: I-Multiprotocol Label Switching (MPLS) ngumqolo omtsha we-IP weteknoloji yenethiwekhi. I-MPLS yazisa ingqikelelo yokutshintsha kweleyibhile ejolise kunxibelelwano kwinethiwekhi ye-IP engaxhunywanga, idibanisa itekhnoloji yendlela yesithathu kunye netekhnoloji yokutshintsha okwesibini, kwaye inika fu...

I-Antenna sisixhobo sokwenziwa, ikakhulu sichaphazela amandla e-OTA kunye novakalelo, ukugubungela kunye nomgama, kwaye i-OTA yindlela ebalulekileyo yokuhlalutya kunye nokusombulula ingxaki yokuphuma, ngokuqhelekileyo thina ikakhulu kwiiparameters ezilandelayo (ezi parameters zilandelayo aziyicingi impazamo yebhubhoratri; eyona nto...
