PON bivuga imiyoboro ya optique ya fibre optique, ninzira yingenzi ya serivise yagutse ya serivise igomba gukorwa.
Ikoranabuhanga rya PON ryatangiye mu 1995. Nyuma, ukurikije itandukaniro riri hagati yamakuru ahuza urwego rwumubiri, tekinoroji ya PON yagiye igabanywa buhoro buhoro muri APON, EPON, na GPON.Muri byo, ikoranabuhanga rya APON ryakuweho nisoko kubera igiciro cyaryo kinini kandi ryagutse.
1 、 EPON
Ethernet ishingiye kuri tekinoroji ya PON.Ifata ingingo-kuri-kugwiza imiterere hamwe na pasiporo optique yoherejwe kugirango itange serivisi nyinshi kuri Ethernet.Ikoranabuhanga rya EPON risanzwe na IEEE802.3 Itsinda ryakazi rya EFM.Muri iki gipimo, tekinoroji ya Ethernet na PON irahujwe, tekinoroji ya PON ikoreshwa murwego rwumubiri, protocole ya Ethernet ikoreshwa murwego rwo guhuza amakuru, naho topologiya ya PON ikoreshwa kugirango tumenye Ethernet.
Ibyiza bya tekinoroji ya EPON nigiciro gito, umurongo mwinshi, ubunini bukomeye, guhuza na Ethernet ihari, hamwe nubuyobozi bworoshye.
Ibisanzwe bisanzwe bya EPON optique kumasoko ni:
(1) EPON OLT PX20 + / PX20 ++ / PX20+
.Intera yoherejwe ni 20KM, uburyo bumwe, interineti ya SC, hamwe na DDM.
10G EPON irashobora kugabanywamo ibyiciro bibiri ukurikije igipimo: uburyo bwa asimmetric nuburyo bwo guhuza.Igipimo cyo kumanuka cyuburyo bwa asimmetric ni 10Gbit / s, igipimo cyo kuzamuka ni 1Gbit / s, naho igipimo cyo kuzamuka no kumanuka cyuburyo bwa simmetrike ni 10Gbit / s.
2 、 GPON
GPON yasabwe bwa mbere n’umuryango FSAN muri Nzeri 2002. Hashingiwe kuri ibyo, ITU-T yarangije gushyiraho ITU-T G.984.1 na G.984.2 muri Werurwe 2003, irangiza G.984.1 na G.984.2 muri Gashyantare na Kamena. 2004. 984.3.Rero amaherezo yashizeho umuryango usanzwe wa GPON.
Ikoranabuhanga rya GPON nigisekuru gishya cya Broadband passive optique ihuriweho hamwe igendeye kuri ITU-TG.984.x.Ifite ibyiza byinshi nkumuyoboro mwinshi, gukora neza, gukwirakwiza cyane, imikoreshereze yabakoresha, kandi bifatwa nababikoresha benshi nkukumenyekanisha Ikoranabuhanga ryiza rya serivise zogukwirakwiza umurongo mugari no guhindura byimazeyo.
Ibisanzwe GPON optique modules kumasoko ni:
