Uma kukhulunywa ngobuchwepheshe besimanje bezokuxhumana, amagama amabili avame ukuvela i-EPON (Ethernet Passive Optical Network) kanye ne-GPON (Gigabit Passive Optical Network).Zombili zisetshenziswa kakhulu embonini yezokuxhumana, kodwa yimuphi umehluko wangempela phakathi kwalokhu okubili?
I-EPON ne-GPON izinhlobo zamanethiwekhi okusebenza asebenzisa ubuchwepheshe be-fiber optic ukudlulisa idatha.Nokho, kukhona umehluko omkhulu phakathi kwalokhu okubili.
I-EPON, eyaziwa nangokuthi i-Ethernet PON, isekelwe ezingeni le-Ethernet futhi ivamise ukusetshenziselwa ukuxhumanisa amakhasimende ahlala kanye namabhizinisi amancane ku-inthanethi.Isebenza ngesivinini esilinganayo sokulayisha nokulanda esingu-1 Gbps, okuyenza ifaneleke ukuhlinzeka ngokufinyelela ku-inthanethi okushesha kakhulu.
Ngakolunye uhlangothi, i-GPON, noma i-Gigabit PON, ubuchwepheshe obuthuthuke kakhulu obungahlinzeka ngomkhawulokudonsa omkhulu kanye nokuhlanganisa okubanzi.Isebenza ngesivinini esiphezulu kune-EPON, inamandla okudlulisa idatha ngesivinini esifika ku-2.5 Gbps ezansi nomfula kanye no-1.25 Gbps phezulu nomfula.I-GPON ivamise ukusetshenziswa abahlinzeki besevisi ukuze banikeze izinsiza zokudlala kathathu (i-inthanethi, i-TV, nocingo) kumakhasimende okuhlala nawomabhizinisi.
I-GPON OLT LM808G yethuinesethi ecebile yezivumelwano Zesendlalelo 3, okuhlanganisa i-RIP, OSPF, BGP, ne-ISIS, kuyilapho i-EPON isekela i-RIP ne-OSPF kuphela.Lokhu kunikeza yethuI-LM808G GPON OLTizinga eliphezulu lokuguquguquka nokusebenza, okubalulekile endaweni yanamuhla yenethiwekhi enamandla.
Sengiphetha, nakuba i-EPON ne-GPON zisetshenziswa kakhulu embonini yezokuxhumana, kunomehluko obalulekile phakathi kwalokhu okubili ngokuya ngesivinini, ububanzi kanye nezicelo.Njengoba ubuchwepheshe buthuthuka, kuzojabulisa ukubona ukuthi buthuthuka futhi buqhubeka kanjani nokubumba ikusasa lamanethiwekhi ezokuxhumana.
