I-LM808XGS I-PON OLT idityaniswe kakhulu, inamandla amakhulu XG(S)-PON OLT yabasebenzi, ii-ISPs, amashishini, kunye nezicelo zekhampasi.Imveliso ilandela umgangatho wezobuchwepheshe we-ITU-T G.987 / G.988, kwaye unokuhambelana neendlela ezintathu ze-G / XG / XGS ngexesha elifanayo.Inkqubo ye-asymmetric (up 2.5Gbps, phantsi kwe-10Gbps) ibizwa ngokuba yi-XGPON, kunye nenkqubo ye-symmetric (up 10Gbps, phantsi kwe-10Gbps) ibizwa ngokuba yi-XGSPON.Imveliso inokuvuleka okuhle, ukuhambelana okuqinileyo, ukuthembeka okuphezulu kunye nemisebenzi epheleleyo yesofthiwe, kunye neyunithi ye-optical Network (ONU), inokubonelela abasebenzisi nge-broadband, izwi, ividiyo, ukucupha kunye nolunye ufikelelo olubanzi lwenkonzo.Ingasetyenziswa ngokubanzi kwi-FTTH yabaqhubi ukufikelela, i-VPN, ukufikelela kurhulumente kunye nokufikelela kwipaki yeshishini, ukufikelela kwinethiwekhi yekhampasi, i-ETC.I-XG (S)-PON OLT ibonelela nge-bandwidth ephezulu.Kwiimeko zesicelo, uqwalaselo lwenkonzo kunye ne-O&M njengelifa ngokupheleleyo iGPON.

I-LM808XGS PON OLT yi-1U kuphela ubude, kulula ukuyifaka kunye nokugcina, kunye nokugcina indawo.Ixhasa uthungelwano oluxubeneyo lweentlobo ezahlukeneyo zee-ONU, ezinokonga iindleko ezininzi kubaqhubi.Kwicandelo lezonxibelelwano, ukugcina ubuchwephesha bamvanje kubalulekile ukuba amashishini ahlale ekhuphisana.Phakathi kweenketho ezininzi eziphambili ezikhoyo, ukhetho olubini oludumileyo yi-XGSPON OLT kunye neGPON OLT.Zombini iitekhnoloji zibonelela ngesantya esiphezulu sokufikelela kwi-Intanethi kwaye zisebenza njengesiseko esisisiseko sokunikezela ngeenkonzo zebroadband kubasebenzisi bokuphela.Nangona kunjalo, kukho iiyantlukwano eziphawulekayo ezibenza bahluke.Kweli nqaku, siza kuphonononga lo mahluko kwaye sikuncede uqonde ukuba loluphi ukhetho olulungele iimfuno zeshishini lakho.

Okokuqala, masiqonde ukuba i-XGSPON OLT kunye ne-GPON OLT imele ntoni.I-OLT imele i-Optical Line Terminal, ngelixa i-XGSPON kunye ne-GPON ziyimigangatho emibini eyahlukeneyo yothungelwano lwe-optical network.I-XGSPON ngowona mgangatho wakutsha nje nophezulu, ubonelela ngezantya ezikhawulezayo kunye ne-bandwidth enkulu kune-GPON.I-XGSPON isebenza ngokulinganayo kwi-10Gbps, ngelixa i-GPON isebenza ngesantya esisezantsi se-2.5Gbps kunye nesantya esiphezulu se-1.25Gbps.

Omnye umahluko omkhulu phakathi kweXGSPON OLT kunye neGPON OLT linani lamazibuko akhoyo.I-XGSPON OLT iqhele ukuba namazibuko asi-8, ngelixa iGPON OLT iqhele ukuba namazibuko ama-4 okanye ambalwa.Oku kuthetha ukuba i-XGSPON OLT inokudibanisa inani elikhulu le-ONU (Iiyunithi zeNethiwekhi ye-Optical) okanye abasebenzisi bokugqibela, okwenza ukuba ifaneleke ngakumbi kumashishini anenani elikhulu labasebenzisi.

Omnye umahluko obonakalayo ngumsebenzi weLayer 3.XGSPON OLT ibonelela umaleko otyebileyo imisebenzi emithathu, kuquka RIP/OSPF/BGP/ISIS protocols, ephucula ubuchule indlela kwaye ivumela uqwalaselo womnatha ezintsonkothileyo ngakumbi.Kwelinye icala, i-GPON OLT inemisebenzi eqingqiweyo yomzila kwaye idla ngokuba nemigaqo esisiseko efana ne-RIP.

Umthamo we-Uplink port yenye into ebalulekileyo ekufuneka uyiqwalasele.I-XGSPON OLT inikezela ngezinketho ze-uplink ze-port ukuya kwi-100G, ngelixa i-GPON OLT ngokuqhelekileyo ixhasa umthamo ophantsi we-uplink.Esi sikhundla siphezulu sokunyuka kwenza i-XGSPON OLT ibe yinto engcono kumashishini afuna i-bandwidth enkulu kuzo zombini i-traffic ephezulu kunye nezantsi.

Zombini i-XGSPON OLT kunye ne-GPON OLT zibonelela ngeendlela ezimbini zokubonelela ngombane.Olu phawu lokungafuneki luqinisekisa inkonzo engaphazamisekiyo naxa kukho ukusilela kombane.Kodwa kubalulekile ukuqaphela ukuba ayizizo zonke ii-OLTs kwimarike ezinikezela ngeendlela ezimbini zamandla, ngoko ke kubalulekile ukukhetha umboneleli othembekileyo onokunikezela ngeli nqaku.

Ngokokhuseleko, zombini i-XGSPON OLT kunye ne-GPON OLT zibonelela ngemisebenzi efana ne-DDOS ekhuselekileyo kunye nokukhusela intsholongwane.La manyathelo okhuseleko akhusela iziseko zothungelwano kwizisongelo ze-cyber ezinokubakho kwaye aqinisekise ukuba abasebenzisi bokugqibela banonxibelelwano oluthembekileyo, olukhuselekileyo.

Ukuhambelana nezinye iimpawu ze-ONU yinto ebalulekileyo yokuqwalaselwa xa ukhetha i-OLT.Zombini i-XGSPON OLT kunye ne-GPON OLT zibonelela ngokuhambelana nee-ONU ezahlukeneyo, ziqinisekisa ukuguquguquka ekuhanjisweni kwenethiwekhi kunye nokudibanisa.

Ngokolawulo lwenkqubo, i-XGSPON OLT kunye ne-GPON OLT zibonelela ngeendlela ezibanzi ezifana ne-CLI, i-Telnet, i-WEB, i-SNMP V1/V2/V3, kunye ne-SSH2.0.Ezi protocols zolawulo zivumela abalawuli bothungelwano ukuba babeke iliso kwaye balawule ngokufanelekileyo iiOLT kunye nee-ONU.

Ngokufutshane, zombini i-XGSPON OLT kunye ne-GPON OLT lukhetho oluhle kakhulu kumashishini afuna ukuhambisa i-high-speed broadband infrastructure.I-XGSPON OLT inikezela ngezantya ezikhawulezayo, amazibuko angaphezulu, ubuchule obuphezulu beLayer 3, isakhono esiphakamileyo sokuphakama kunye neempawu zokhuseleko ezinamandla.Ngakolunye uhlangothi, kuthungelwano oluncinci olunabasebenzisi abambalwa, i-GPON OLT yindlela ebiza kakhulu.Ekugqibeleni, ukhetho phakathi kwe-XGSPON OLT kunye ne-GPON OLT ixhomekeke kwiimfuno zeshishini lakho kunye nohlahlo lwabiwo-mali.Ukukhetha umthengisi ohloniphekileyo njengenkampani yethu enobuchule kunye namava kwishishini kubalulekile ekuqinisekiseni ukuthunyelwa kwenethiwekhi okuthembekileyo nokungenamthungo.Ngaphezulu kweminyaka eyi-10 yamava kwintsimi yonxibelelwano yaseChina, sibonelela ngeemveliso ezininzi kunye neenkonzo, kuquka i-OLT, i-ONU, i-switches, i-routers kunye ne-4G / 5G CPE.Iimveliso zethu zixhasa i-GPON, i-XGPON kunye ne-XGSPON kwaye zibonisa ubuchule obutyebileyo be-Layer 3 kunye neempawu zokhuseleko oluphezulu.Sinikezela ngeenkonzo ze-OEM kunye ne-ODM, siqinisekisa ukuguquguquka kunye neenketho zokwenza ngokwezifiso kubathengi bethu.Qhagamshelana nathi namhlanje ukuxoxa ngeemfuno zakho zenethiwekhi kwaye ufumane esona sisombululo silungileyo kwishishini lakho.
