Izixhobo ze-OLT zineendlela ezimbini eziphambili zilandelayo: okokuqala, ukuxhaswa kwekhadi lebhodi ye-PON ye-10G, kubandakanywa nokunyuka komthamo wokutshintshiselana kwe-slot kunye nomthamo wokutshintshiselana ngokubanzi, kunye nenkxaso ye-uplink ye-port kwii-bandwidth ezinkulu ezifana ne-10GE, njl. kunye ne...

(1) I-10G ye-PON yeTekhnoloji yophuhliso Umzila we-EPON olawulwa yi-IEEE, kunye ne-GPON elawulwa yi-ITU zombini ziguqukela kwi-10 GPON isigaba okwangoku kwaye ukucwangciswa okulandelayo kubini i-100G PON.Kukho iiyantlukwano ezithile kwiindlela ezithile zokuzivelela, kunye ne-evo ehambelanayo...

Inethiwekhi ebizwa ngokuba yi-PON iqulethwe ngamacandelo amathathu: i-OLT, i-ODN kunye ne-ONU.Isixhobo se-OLT sifumaneka kwisiseko se-topology yenethiwekhi.Ifikelela kwiinkonzo ezininzi zothungelwano ukuya phezulu kunye neenkonzo zabasebenzisi abaninzi ukuhla nge-ODN.Yindawo ebalulekileyo yenkonzo agg...

Umzila yinkqubo apho i-router ifumana ipakethi kwi-interface enye, iqondise ipakethi ngokwedilesi yayo kwaye iyidlulisele kwenye i-interface.Sisixhobo sokudlulisa ipakethi somaleko wothungelwano olusebenza kumaleko wesithathu we-OSI ireferensi...

I-SONET: i-synchronous optical network, umgangatho wokuhanjiswa kwedijithali, yaziswa e-United States ngo-1988. Inqanaba le-1 uphawu lombane lichazwa njenge-STS-1, kwaye inqanaba le-1 ye-optical signal ichazwa njenge-OC-1, kunye nesantya se-51.84Mb. /s.Ngesi siseko, phucula ngokusebenzisa...

Iikhrayitheriya ze-IPv4 zachazwa ekupheleni koo-1970.Ekuqaleni kweminyaka yoo-1990, ukusetyenziswa kweWWW kwakhokelela ekuphuhlisweni okuqhumayo kwe-Intanethi.Ngeentlobo zezicelo ze-Intanethi eziya zisiba nzima kunye nokwahluka kwe-terminal, ubonelelo lwe-indep yehlabathi...
