Q5: Yintoni i-FTTH/FTTO?
Yintoni i-FTTH/FTTO?
Kwihlabathi lanamhlanje eliphakathi kwedijithali, uqhagamshelo lwe-intanethi olukhawulezayo aluseyonto yodidi kodwa luyimfuneko.Njengoko imfuno ye-intanethi ekhawulezayo nethembekileyo iqhubeka nokukhula, iinkampani zonxibelelwano ziyaqhubeka nokuphonononga itekhnoloji entsha ukuhlangabezana neemfuno zabathengi.I-Gigabit Passive Optical Network (GPON) bubuchwepheshe obuguqula ishishini lebroadband.Kweli nqaku, siza kuhlolisisa iingenelo ze-GPON, ngokukodwa ukusetyenziswa kwayo kwe-16-port, i-OLT enemigangatho emithathu kunye ne-FTTH i-terminal optical optical ukuphucula kakhulu ukusebenza kwenethiwekhi kunye nokusebenza.
I-GPON yi-fiber-optic network architecture enikezela ngesantya esiphezulu se-Intanethi, ilizwi, kunye neenkonzo zevidiyo kubasebenzisi beendawo zokuhlala kunye nezoshishino.Isebenzisa i-point-to-multipoint topology, isebenzisa i-passive optical splitters ukusabalalisa idatha kubathengi abaninzi ngaxeshanye.I-GPON isebenzisa i-Layer 2 yothutho indlela yokuhambisa idatha, ukubonelela nge-bandwidth ephawulekayo ukuya kwi-2.5 Gbps ezantsi kunye ne-1.25 Gbps phezulu.
Undoqo wothungelwano lweGPON yitheminali yomgca wokubona (OLT).Ubunakho be-OLT's Layer 3 buvumela ulwabiwo olusebenzayo lwemithombo yothungelwano kunye nomzila okrelekrele wepakethe.Nge-OLT exhasa ubunakho beLayer 3, ababoneleli be-telecom banokuqinisekisa ukugcwala okuphuculweyo, ukunciphisa ukuxinana, kunye nokuphucula ukusebenza kwenethiwekhi.Ukongeza, iLayer 3 OLTs ibonelela ngeempawu zokhuseleko eziphambili ezifana nokucoca i-IP kunye nokukhusela i-firewall ukukhusela inethiwekhi kwiingozi ezinokubakho.
Imodeli ye-fiber-to-the-home (FTTH) inikwe amandla yi-GPON iteknoloji kwaye isebenzisa ii-terminals ze-fiber optic ukubonelela ngoqhagamshelwano lwefayibha ngokuthe ngqo kumakhaya okanye amashishini.Ukuxhotyiswa ngamachweba amaninzi e-16, ezi zixhobo zincinci, ezidibeneyo ziyakwazi ukuphatha ngokulula ukuhanjiswa kunye nokupheliswa kweempawu ze-optical, ukuqinisekisa uxhulumaniso olungenamthungo kuyo yonke inethiwekhi.Ii-terminals ze-FTTH ezibonakalayo zisebenza njengebhulorho phakathi kwe-fiber optical kunye ne-Ethernet, eyenza ukuhanjiswa kwedatha ye-high-speed kunye neenkonzo zonxibelelwano ezithembekileyo.
I-GPON ineenzuzo ezininzi xa idityaniswe ne-OLT enemigangatho emithathu kunye ne-FTTH ye-optical terminals.Okokuqala, ibonelela ngomthamo ongalinganiyo we-bandwidth ukuhlangabezana neemfuno zedatha ezikhulayo zabathengi.Ubuchwephesha bukwanciphisa ukusetyenziswa kwamandla, okwenza kube sisisombululo esilungele ukusingqongileyo.Ukongeza, i-GPON's scalability yenza ukuba ukwandiswa kwenethiwekhi okungabizi kakhulu kunye neziseko zobungqina bexesha elizayo.
Ngamafutshane, indibaniselwano ye-16-port, i-OLT enemigangatho emithathu kunye ne-FTTH i-terminal optical itshintshe ngokupheleleyo i-broadband industry.Itekhnoloji yeGPON izisa uqhagamshelo olukhawulezayo, ulawulo olusebenzayo lwezixhobo kunye nokhuseleko olongeziweyo kuthungelwano lwezonxibelelwano.Ngokwamkela i-GPON, ababoneleli ngeenkonzo banokubonelela abathengi babo nge-Intanethi engenamthungo, iinkonzo zelizwi kunye nevidiyo ezihlangabezana kwaye zigqithise ukulindela kwabo ngeli xesha ledijithali.
