EPON ni tekinoroji ya PON ishingiye kuri Ethernet.Ikoresha tekinoroji ya PON kurwego rwumubiri, protocole ya Ethernet kumurongo uhuza amakuru, kwinjira kuri Ethernet ukoresheje topologiya ya PON, hamwe na serivise yuzuye yo kubona amakuru, ijwi, na videwo ukoresheje fibre optique.
Ibisobanuro bya EPON:
EPON yohereza kandi yakira ibimenyetso kuri fibre imwe.Ubu buryo bwitwa uburyo bumwe bwo gukwirakwiza fibre fibre.Ukoresheje WDM yumurongo wigice cyoguhuza tekinoroji, kwanduza fibre imwe ya fibre imwe igerwaho hamwe nuburebure butandukanye (kumanuka 1490nm, hejuru ya 1310nm), kandi amakuru yo hejuru no mumasoko yamakuru yoherejwe icyarimwe kuri fibre imwe itagize ingaruka kuri mugenzi we.
Muri icyo gihe, 1000 BASE-PX-10 U irasobanuwe / D na 1000 BASE-PX-20 U / D PON ya optique ihuza intera ntarengwa yohereza kilometero 10 na 20 km.EPON irashobora gutanga 1.25 Gbit / s hejuru. n'umuyoboro mugari.Numuyoboro mwiza wa optique ushingiye kuri Ethernet.OLT ifata Ethernet enapsulation kandi ikohereza imiterere ya Ethernet.Kubwibyo, EPON ishingiye kumiterere ya 802.3.
Ukurikije amasezerano ya IEEE802.3ah-2004: imbaraga zo kohereza uruhande rwa OLT zirenze 2dBm, kandi sensibilité yo kwakira ni <-27dBm;kuri ONU yohereza imbaraga zirenze -1dBm, kwakira sensibilité ni <-24dBm, gutakaza umurongo wose wa optique ugera kuri <24dB, ukamanuka kuri <23.5dB.Gutakaza EPON hejuru ya 1310nm no kumanuka 1490nm uburebure bwa fibre ya G.652 ni 0.3dB / km.Muncamake, ingengo yingufu ningingo yingenzi kuri intera ndende ya EPON.
Ibiranga ibicuruzwa bya EPON
①1.25Gbps ihuza simusiga imwe ya fibre ibyerekezo byombi
②3.3V voltage ikora
FunctionDDM imikorere yo kugenzura isuzumabumenyi
Interanti-electromagnetic kwivanga, hamwe no kurinda anti-static
OmpKurikiza IEC-60825 Icyiciro cya 1 cyumutekano wa laser
Temperature Ubushyuhe bwo gukora: 0 ℃ ~ 70 ℃
Ikoreshwa rya tekinoroji ya EPON
① Kubakoresha rusange, uburyo bwo gusaba nka FTTH na FTTB / C / Cab burashobora gukoreshwa.
②Koresha abakoresha ubucuruzi, uburyo butandukanye bwo gushyira mubikorwa nka FTTO, FTTB, cyangwa FTTC burashobora kwakirwa ukurikije ibikenerwa mubucuruzi butandukanye hamwe nubunini bwabakoresha.
③ “Ijisho ryisi yose” hamwe nizindi porogaramu zisaba umurongo mwinshi ugereranije (cyane cyane umurongo wo hejuru) ushobora gukoresha EPON nkuburyo bwo kugera.PON isimbuza umwimerere wa Layeri 2 / Layeri 3 ihindura mugisubizo cya analogi ya rezo, mugihe nayo izigama fibre transibiver nyinshi, kandi ntisaba ibikoresho bya videwo optique.
④Mu gihe habuze ibikoresho bya fibre optique, nkumushinga wumudugudu wumudugudu, gahunda yo gutandukanya optique hamwe no kugabana urwego rwinshi hamwe nimbaraga zo kugabana ku buryo budasanzwe irashobora gukoreshwa, ni ukuvuga ko imbaraga zingana mugihe hari cores imwe cyangwa nyinshi The optique itandukanya ihuza ingingo kumurongo.
EPON yujuje byuzuye umurongo mugari wibisabwa kubakiriya ba neti, kandi irashobora gutanga imbaraga kandi byoroshye kugabura umurongo ukurikije impinduka zikenewe kubakoresha, bigatuma ubuzima bwabaturage batuye neza, umutekano kandi byoroshye.
