A matsayin manyan mambobi biyu na hanyoyin sadarwa na gani, EPON da GPON kowannensu yana da nasa cancantar, yana fafatawa da juna, suna gamawa da juna, kuma suna koyi da juna.Masu zuwa za su kwatanta su ta fuskoki daban-daban.
Rate
EPON yana ba da tsayayyen haɓakawa da saukar da 1.25 Gbps, yana ɗaukar lambar layin 8b/10b, kuma ainihin ƙimar shine 1Gbps.
GPON tana goyan bayan matakan ƙima iri-iri, waɗanda zasu iya tallafawa asymmetric uplink da downlink rates, 2.5Gbps ko 1.25Gbps don saukar da ƙasa, da 1.25Gbps ko 622Mbps don haɓakawa.Ana ƙididdige ƙimar haɗin kai da ƙasa bisa ga ainihin buƙatu, kuma an zaɓi na'urorin gani masu dacewa don ƙara ƙimar ƙimar na'urorin gani.
Raba rabo
Rarraba rabo shine nawa ONUs (tashashin mai amfani) ke ɗaukar ta tashar OLT (ofishin tsakiya).
Ma'auni na EPON yana bayyana rabon rabo na 1:32.
Ma'auni na GPON yana bayyana ma'anar raba rabo: 1:32;1:64;1:128.
A gaskiya ma, tsarin EPON na fasaha na iya samun babban rabo mai girma, kamar 1: 64, 1: 128, kuma tsarin kulawa na EPON zai iya tallafawa ƙarin ONUs.Raga rabon an iyakance shi ta hanyar fihirisar aikin na'urar gani, kuma babban rabon rabo zai sa farashin na'urar gani ta tashi sosai.
GPON yana ba da zaɓuɓɓuka da yawa, amma fa'idar farashi ba a bayyane yake ba.Matsakaicin nisa watsa Matsakaicin nisa na zahiri wanda tsarin GPON zai iya tallafawa.Lokacin da rabon tsagawar gani shine 1:16, yakamata ya goyi bayan matsakaicin nisan jiki na 20km;lokacin da rabon tsagawar gani shine 1:32, yakamata ya goyi bayan iyakar tazarar jiki na 10km.EPON daidai yake da wannan, amma daidai yake gabaɗaya.
Singancin sabis
Ka'idar Ethernet kanta ba ta da ikon sarrafa QoS.Don haka, don ba da damar EPON don yiwa masu amfani hidima, an gabatar da ra'ayi na cibiyar sadarwa na yanki mai kama-da-wane.VLAN yana ba da shawarar cewa za a iya canza fifikon tantance firam ɗin da aka karɓa don aza harsashin QOS, amma saboda VLAN ana aiwatar da shi da hannu, wanda ke da tsada sosai.Kuma GPON yana da nasa ingantattun damar sabis na QoS.
EPON da GPON kwatanta Layer mahada
Idan aka kwatanta da GPON, EPON ya fi sauƙi kuma ya fi kai tsaye.A cikin tsantsar watsawar Ethernet, hanyoyin ɓoye biyu da tallafin ATM na GPON ba za su taka rawar gani ba.
Koyaya, a cikin samun damar sabis na hanyar sadarwa, EPON ya dace da sabis na watsa bayanai kawai, yayin da GPON zai iya ba da sabis na uku-biyu.
EPON shine mafita na duk-Ethernet wanda ke cika cikakkiyar dacewa da halaye, aiki da aikin ka'idar Ethernet, yayin da GPON yana amfani da hanyar sadarwa na gani na gani/fasahar tsarin dijital na aiki tare da ƙa'idar gamayya don watsa Ethernet.
EPON da GPON suna da nasu amfani da rashin amfani.Dangane da alamun aiki, GPON ya fi EPON, amma EPON yana da fa'ida cikin lokaci da farashi.GPON yana kamawa.Ana sa ido ga kasuwar samun damar watsa shirye-shirye na gaba, maiyuwa bazai zama wanda ya maye gurbin wasu ba, amma yana tare kuma ya cika juna.Ga abokan ciniki tare da babban bandwidth, sabis da yawa, QoS da bukatun tsaro, da fasahar ATM a matsayin cibiyar sadarwa na baya, GPON zai kasance. mafi dacewa.Don ƙungiyoyin abokan ciniki masu tsada tare da ƙarancin QoS da buƙatun tsaro, EPON ya zama babba.
