LM808XGS PON OLT ndi gulu lophatikizika kwambiri, lalikulu XG(S)-PON OLT la ogwira ntchito, ma ISPs, mabizinesi, ndi mapulogalamu apasukulu.Chogulitsacho chimatsatira ndondomeko yaukadaulo ya ITU-T G.987/G.988, ndipo imatha kukhala yogwirizana ndi mitundu itatu ya G/XG/XGS nthawi yomweyo.Dongosolo la asymmetric (mpaka 2.5Gbps, pansi pa 10Gbps) limatchedwa XGPON, ndi symmetric system (mmwamba 10Gbps, pansi 10Gbps) amatchedwa XGSPON.Zogulitsa zili ndi kutseguka kwabwino, kugwirizanitsa mwamphamvu, kudalirika kwakukulu ndi ntchito zonse za mapulogalamu，Pamodzi ndi optical Network unit (ONU), ikhoza kupatsa ogwiritsa ntchito burodibandi, mawu, mavidiyo, kuyang'anitsitsa ndi zina zambiri zothandizira.Iwo akhoza ankagwiritsa ntchito mu FTTH kupeza opareshoni, VPN, boma ndi ogwira ntchito paki kupeza, kampasi maukonde mwayi, ETC.XG(S) -PON OLT imapereka bandwidth yapamwamba.M'mawonekedwe ogwiritsira ntchito, kasinthidwe ka ntchito ndi O&M yolandira GPON kwathunthu.
LM808XGS PON OLT ndi 1U yokha kutalika, yosavuta kukhazikitsa ndi kukonza, ndikusunga malo.Imathandizira maukonde osakanikirana amitundu yosiyanasiyana ya ONU, omwe amatha kupulumutsa ndalama zambiri kwa ogwiritsa ntchito.XGS-PON OLT kapena XG(S)-PON Optical Line Terminal ndi njira yolumikizira netiweki yomwe ikusintha momwe timalumikizirana ndi intaneti. .OLT ndi chipangizo chogwira ntchito kwambiri, chophatikizika kwambiri chopangidwira ogwiritsa ntchito, ma ISPs, mabizinesi ndi mapulogalamu apasukulu.8PORT XGSPON OLT ndi chitsanzo chabwino kwambiri chaukadaulo uwu, wopereka madoko 8 ndi ma 100G okwera kuti azitha kulumikizana mwachangu.
Ndiye, kodi XGS-PON OLT imayimira chiyani?XGS-PON imayimira 10 Gigabit Passive Optical Network, ukadaulo womwe umapereka ma intaneti othamanga kwambiri komanso odalirika a FTTH (Fiber to the Home) ndi maukonde ena opangidwa ndi fiber.OLT ndi chipangizo chapakati mu PON (Passive Optical Network) chomwe chimagwiritsa ntchito mzere umodzi wa fiber optic kulumikiza ogwiritsa ntchito ambiri ku intaneti.
8PORT XGSPON OLT imagwirizana ndi mitundu ya G/XG/XGS nthawi imodzi, ikupereka kusinthasintha kwakukulu komanso kusinthasintha pazokonda zosiyanasiyana zamaneti.Kuphatikizika kwake kwakukulu komanso kuchuluka kwakukulu kumapangitsa kukhala koyenera kwa mabungwe omwe akufuna kukweza maukonde awo kuti athandizire zofuna zomwe zikukula pa intaneti yothamanga kwambiri.
Chimodzi mwazinthu zazikulu za XGS-PON OLT ndi kutseguka, kugwirizana ndi kudalirika.Zapangidwa kuti zizigwira ntchito mosasunthika ndi zida zosiyanasiyana zamakina ndi mapulogalamu, kulola kuphatikizika kosavuta kumalo omwe alipo kale.Izi, kuphatikiza ndi magwiridwe ake athunthu apulogalamu, zimatsimikizira kugwira ntchito kosalala komanso kothandiza.
Mwachidule, XGS-PON OLT (monga 8PORT XGSPON OLT) ndiukadaulo wosintha masewera womwe umakhazikitsa mulingo watsopano wolumikizira netiweki.Ndi machitidwe ake apamwamba, ogwirizana komanso odalirika, ndi abwino kwa mabungwe omwe akufunafuna njira yothetsera intaneti yolimba komanso yotsimikiziranso zam'tsogolo.Kaya ndinu opareshoni, ISP, bizinesi kapena sukulu, XGS-PON OLT ikhoza kukupatsani njira yamphamvu komanso yabwino yoperekera ogwiritsa ntchito intaneti mwachangu komanso modalirika.
