Izici Zomkhiqizo

● 8 x XG(S)-PON/GPON Imbobo

● Umsebenzi Wokusekela Wesendlalelo sesi-3: RIP/OSPF/BGP/ISIS

● 8x10GE/GE SFP + 2x100G QSFP28

● Sekela izivumelwano eziningi zokuphinda zingasebenzi: I-FlexLink/STP/RSTP/MSTP/ERPS/LACP

● 1 + 1 Ukungadingeki kwamandla

I-LM808XGS PON OLT ihlanganiswe kakhulu, inamandla amakhulu i-XG(S)-PON OLT yama-opharetha, ama-ISP, amabhizinisi, nezicelo zekhampasi.Umkhiqizo ulandela izinga lobuchwepheshe le-ITU-T G.987/G.988, futhi lingahambisana nezindlela ezintathu ze-G/XG/XGS ngesikhathi esifanayo.Isistimu ye-asymmetric (phezulu 2.5Gbps, phansi 10Gbps) ibizwa ngokuthi i-XGPON, kanye nesistimu ye-symmetric (phezulu i-10Gbps, phansi i-10Gbps) ibizwa ngokuthi i-XGSPON.Umkhiqizo unokuvuleka okuhle, ukuhambisana okuqinile, ukuthembeka okuphezulu kanye nemisebenzi ephelele yesofthiwe, Kanye neyunithi ye-optical Network (ONU), ingahlinzeka abasebenzisi nge-broadband, izwi, ividiyo, ukugadwa nokunye ukufinyelela kwesevisi okuphelele.Ingasetshenziswa kabanzi ekufinyeleleni kwe-FTTH yabasebenzisi, i-VPN, ukufinyelela kukahulumeni kanye nepaki yebhizinisi, ukufinyelela kwenethiwekhi yekhampasi, i-ETC.I-XG(S)-PON OLT inikeza umkhawulokudonsa ophezulu.Ezimeni zohlelo lokusebenza, ukucushwa kwesevisi kanye ne-O&M njengefa ngokuphelele i-GPON.

I-LM808XGS PON OLT ingu-1U kuphela ubude, kulula ukuyifaka nokuyinakekela, futhi yonga isikhala.Isekela amanethiwekhi axubile ezinhlobo ezahlukene zama-ONU, angonga izindleko eziningi kubasebenzisi.Emkhakheni wezokuxhumana, ukuhambisana nobuchwepheshe bamuva kubalulekile ukuze amabhizinisi ahlale encintisana.Phakathi kwezinketho eziningi ezithuthukisiwe ezitholakalayo, izinketho ezimbili ezidume kakhulu i-XGSPON OLT ne-GPON OLT.Bobabili ubuchwepheshe buhlinzeka ngokufinyelela ku-inthanethi ngesivinini esiphezulu futhi busebenza njengengqalasizinda engumgogodla yokuletha izinsiza ze-broadband kubasebenzisi bokugcina.Nokho, kukhona ukuhluka okuphawulekayo okubahlukanisayo.Kulesi sihloko, sizohlola lo mehluko futhi sikusize uqonde ukuthi iyiphi inketho efanelekela kangcono izidingo zebhizinisi lakho.

Okokuqala, masiqonde ukuthi i-XGSPON OLT ne-GPON OLT imelani.I-OLT imele i-Optical Line Terminal, kuyilapho i-XGSPON ne-GPON kungamazinga amabili ahlukene wamanethiwekhi okubona angenzi lutho.I-XGSPON iyindinganiso yakamuva nethuthuke kakhulu, ehlinzeka ngesivinini esisheshayo nomkhawulokudonsa omkhulu kune-GPON.I-XGSPON isebenza ngokulinganayo ku-10Gbps, kuyilapho i-GPON isebenza ngenani eliphansi eliphansi lomfula elingu-2.5Gbps kanye nezinga elikhuphukayo elingu-1.25Gbps.

Umehluko owodwa omkhulu phakathi kwe-XGSPON OLT ne-GPON OLT inani lamachweba atholakalayo.I-XGSPON OLT ngokuvamile inamachweba angu-8, kuyilapho i-GPON OLT ngokuvamile inamachweba angu-4 noma ambalwa.Lokhu kusho ukuthi i-XGSPON OLT ingaxhuma inombolo enkulu yama-ONU (Optical Network Units) noma abasebenzisi bokugcina, iyenze ifaneleke kakhulu amabhizinisi anenani elikhulu labasebenzisi.

Omunye umehluko ophawulekayo ukusebenza kwe-Layer 3.I-XGSPON OLT inikezela ngesendlalelo esicebile semisebenzi emithathu, okuhlanganisa amaphrothokholi e-RIP/OSPF/BGP/ISIS, ethuthukisa amandla omzila futhi ivumele ukulungiselelwa kwenethiwekhi okuyinkimbinkimbi.Ngakolunye uhlangothi, i-GPON OLT inemisebenzi elinganiselwe yomzila futhi ngokuvamile inezimiso eziyisisekelo ezifana ne-RIP.

Umthamo wembobo ye-Uplink ungenye into ebalulekile okufanele icatshangelwe.I-XGSPON OLT inikeza izinketho zembobo ye-uplink kufika ku-100G, kuyilapho i-GPON OLT ngokuvamile isekela umthamo ophansi we-uplink.Lo mthamo ophezulu wokuxhumanisa phezulu wenza i-XGSPON OLT ibe ukukhetha okungcono kwamabhizinisi adinga umkhawulokudonsa omkhulu kukho kokubili ithrafikhi ekhuphuka nomfula.

Kokubili i-XGSPON OLT ne-GPON OLT ihlinzeka ngezinketho zokuphakelwa kwamandla okukabili.Lesi sici sokungadingeki siqinisekisa isevisi engaphazamiseki ngisho noma kwenzeka ukuphelelwa amandla.Kodwa kubalulekile ukuqaphela ukuthi akuwona wonke ama-OLT emakethe anikeza izinketho zamandla amabili, ngakho-ke kubalulekile ukukhetha umphakeli ohloniphekile onganikeza lesi sici.

Mayelana nokuphepha, kokubili i-XGSPON OLT ne-GPON OLT ihlinzeka ngemisebenzi efana ne-DDOS evikelekile nokuvikelwa kwegciwane.Lezi zinyathelo zokuphepha zivikela ingqalasizinda yenethiwekhi ezingozini ezingase zibe khona futhi ziqinisekisa ukuthi abasebenzisi bokugcina banokuxhumana okuthembekile, okuvikelekile.

Ukuhambisana namanye amabhrendi we-ONU wukucatshangelwa okubalulekile lapho ukhetha i-OLT.Kokubili i-XGSPON OLT ne-GPON OLT inikeza ukuhambisana nama-ONU ahlukahlukene, iqinisekisa ukuguquguquka ekusetshenzisweni kwenethiwekhi nokuhlanganiswa.

Mayelana nokuphathwa kwesistimu, i-XGSPON OLT ne-GPON OLT inikeza izinketho ezibanzi njenge-CLI, i-Telnet, i-WEB, i-SNMP V1/V2/V3, ne-SSH2.0.Lezi zivumelwano zokuphatha zivumela abalawuli benethiwekhi ukuthi baqaphe ngempumelelo futhi balawule ama-OLT nama-ONU.

Kafushane, zombili i-XGSPON OLT ne-GPON OLT ziyizinketho ezinhle kakhulu zamabhizinisi afuna ukuphakela ingqalasizinda ye-broadband enesivinini esikhulu.I-XGSPON OLT inikezela ngesivinini esisheshayo, izimbobo eziningi, amakhono athuthukisiwe e-Layer 3, umthamo ophezulu wokuxhumanisa nezici zokuphepha ezinamandla.Ngakolunye uhlangothi, kumanethiwekhi amancane anabasebenzisi abambalwa, i-GPON OLT iyindlela engabizi kakhulu.Ekugcineni, ukukhetha phakathi kwe-XGSPON OLT ne-GPON OLT kuncike ezidingweni ezithile zebhizinisi lakho kanye nesabelomali.Ukukhetha umdayisi ohloniphekile njengenkampani yethu onobuchwepheshe nolwazi lwemboni kubalulekile ekuqinisekiseni ukuthunyelwa kwenethiwekhi okuthembekile nokungenazihibe.Ngesipiliyoni seminyaka engaphezu kwe-10 emkhakheni wezokuxhumana waseShayina, sihlinzeka ngemikhiqizo namasevisi anhlobonhlobo, okuhlanganisa i-OLT, i-ONU, amaswishi, amarutha kanye ne-4G/5G CPE.Imikhiqizo yethu isekela i-GPON, i-XGPON ne-XGSPON futhi inezici ezicebile ze-Layer 3 nezici zokuphepha ezithuthukisiwe.Sinikezela ngezinsizakalo ze-OEM ne-ODM, siqinisekisa ukuguquguquka nezinketho zokwenza ngokwezifiso kumakhasimende ethu.Xhumana nathi namuhla ukuze uxoxe ngezidingo zakho zokuxhumana futhi uthole isixazululo esingcono kakhulu sebhizinisi lakho.
