Enkathini yanamuhla yenguquko yedijithali, ukuxhumana sekuyingxenye ebalulekile yempilo yethu. Kungakhathaliseki ukuthi kungokwebhizinisi noma ukusetshenziswa komuntu siqu, ukuba nengqalasizinda yenethiwekhi ethembekile nesebenza kahle kubalulekile. Ubuchwepheshe be-EPON (Ethernet Passive Optical Network) bube yisinqumo sokuqala sokudlulisa idatha okuphumelelayo. Kule bhulogi, sizohlolaI-EPON OLT(Optical Line Terminal) futhi uhlole izici zayo ezinhle kakhulu kanye nezinhlelo zokusebenza.
Imisebenzi enamandla ye-EPON OLT
I-EPON OLT iyithuluzi lenethiwekhi elisezingeni eliphezulu elihlanganisa ubuchwepheshe obuthuthukisiwe ukuze linikeze ukuxhumana okungenamthungo kokusetshenziswa kwezindlu nezentengiselwano. Ikakhulukazi i-OLT-E16V, ifakwe izixhumi ezizimele ze-4*GE (zethusi) kanye ne-4*SFP slot ze-uplink, kanye namachweba angu-16*EPON OLT okuxhumana kwe-downlink. Lo mklamo omangalisayo wenza i-OLT ikwazi ukwamukela ama-ONU angu-1024 (ama-Optical Network Units) ngesilinganiso sokuhlukaniswa esingu-1:64, okuqinisekisa inethiwekhi eqinile kubasebenzisi abaningi.
Incane, ilula futhi iyasebenziseka ngezindlela eziningi
Esinye sezici ezivelele ze-EPON OLT usayizi wayo omncane kanye nokwakheka kwe-rack-mount engu-1U engu-19 intshi. Lesi sici siyenza ifaneleke kakhulu ukuthunyelwa emakamelweni amancane noma ezindaweni ezinesikhala esincane se-rack. Isici esincane se-OLT, kuhlanganiswe nokuguquguquka kwayo kanye nokulula kokuthunyelwa, siyenza ibe ukukhetha okuhle kakhulu ezindaweni ezahlukahlukene, kufaka phakathi amayunithi okuhlala, amabhizinisi amancane, kanye nezinhlelo zamabhizinisi.
Ukusebenza Okungalingani Nokusebenza Kahle
Ama-EPON OLTbaziwa ngokusebenza kwabo okuhle kakhulu, futhi i-OLT-E16V ayihlukile. Ngokusebenza kwayo okuphezulu, iqinisekisa ukuxhumana okuzinzile nokuthembekile kwezinhlelo zokusebenza ezahlukahlukene. Kusukela kumasevisi "okudlala kathathu" (kufaka phakathi izwi, ividiyo nedatha) kuya ekuxhumaneni kwe-VPN, ukuqapha ikhamera ye-IP, ukusethwa kwe-LAN yebhizinisi kanye nezinhlelo zokusebenza ze-ICT, i-EPON OLT ingakwazi ukusingatha konke. Ikhono layo lokusekela imisebenzi eminingi ngasikhathi sinye ngaphandle kokwehlisa isivinini noma ikhwalithi yenethiwekhi kuwubufakazi bokusebenza kwayo kahle.
Hlanganisa kalula amanethiwekhi avikela ikusasa
Enye yezinzuzo eziyinhloko ze-EPON OLT yikhono layo lokuhlanganisa kalula nengqalasizinda yenethiwekhi ekhona. Lokhu kuhlanganiswa kuvumela ukukhuliswa kwesikhathi esizayo kanye nokuthuthukiswa okulula, okwenza kube ukutshalwa kwezimali kwesikhathi eside. Njengoba izidingo zethu zokuxhumeka ziqhubeka nokukhula, ama-EPON OLT angazivumelanisa nezimo futhi andise ngaphandle kokuguqulwa okukhulu kwengqalasizinda, okusindisa isikhathi nezinsiza.
Ekuphetheni
Ezweni lapho ukuxhumana kubalulekile khona, ukuba nengqalasizinda yenethiwekhi ethembekile nesebenza kahle kakhulu kubalulekile. I-EPON OLT, ikakhulukazi i-OLT-E16V, ishintsha kakhulu kulokhu. Isici sayo esincane kodwa esinamandla, esihlanganiswe nezinketho zokusebenzisa eziguquguqukayo kanye nokusebenza okuphezulu, senza kube kuhle kakhulu ezinhlobonhlobo zezinhlelo zokusebenza. Ngokutshala imali ku-EPON OLT, ungaqinisekisa ukuxhumana okungenamthungo namuhla nakusasa.
Ngakho-ke, kungakhathaliseki ukuthi ungumnikazi webhizinisi elincane ofuna ukuhlinzeka ngensizakalo ye-inthanethi ethembekile kumakhasimende, noma ibhizinisi elifuna ingqalasizinda yenethiwekhi enamandla, ungabheka i-EPON OLT njengesixazululo sakho. Yamukela amandla okuxhumana okusebenzayo kakhulu futhi uvule amathuba amasha ezweni ledijithali.
