EPON (Ethernet Passive Network Network)
Ethernet Passive Network Network ni tekinoroji ya Pon ishingiye kuri Ethernet. Ifata ingingo kumiterere ya benshi hamwe na fibre ya fibre optique yohereza, itanga serivisi nyinshi hejuru ya Ethernet. Ikoranabuhanga risanzwe na IEEE802.3 Itsinda ryakazi. Muri Kamena 2004, itsinda rya Hoee82.3efm ryasohoye EPON AMERIKA - IEEE802.3Hah (yahujwe na Ieee82.3-2005 muri 2005).
Muri ubu buryo, Ethernet na Pon tekinoroji yahujwe, hamwe na tekinoroji ya Pon ikoreshwa kuri protocole yumubiri na ethernet ikoreshwa kuri data ihuza amakuru, ikoresha topologiya ya Pon kugirango igere kuri ENON kugirango igere kuri ENON kugirango igere kuri ENON kugirango igere kuri ENON kugirango igere kuri ENON kugirango igere kuri Ennet. Kubwibyo, bihuza ibyiza byikoranabuhanga rya Pon na Ethernet: Igiciro gito, giteransants, gutandukana, guhuza na ethernet, ibicunganosoye, nibindi
GPON (Pon ya Gigabit-Ishobora Gusaba)
Ikoranabuhanga ni igisekuru cyanyuma cyumubumbuzi cya optique netratique ihuriweho na ita-tg.984. x isanzwe, ifite ibyiza byinshi nkagabarika, imikorere minini, ahantu hanini, hamwe nimikoreshereze yumukoresha. Bifatwa nabakora benshi nkikoranabuhanga ryiza ryo kugera ku mpinduka mugari kandi zuzuye zo kubona serivisi zurusobe. GPON yasabwe bwa mbere n'umuryango wa FSAN muri Nzeri 2002. Ukurikije ibi, Itu-T yarangije iterambere rya ITU-T G.984.1 na G.984.2 Muri Werurwe 2003. Rero,
Ikoranabuhanga rya GPON ryaturutse ku ngero z'ikoranabuhanga ya Otmpmon buhoro buhoro ryaremye buhoro buhoro mu 1995, kandi Pon ihagaze kuri "optique optique ya optique" mucyongereza. GPON (Gigabit Poweli Network Network) yasabwe bwa mbere n'umuryango wa FSAAN muri Nzeri. Imiterere y'ibanze y'ibikoresho bishingiye kuri tekinoroji ya GPON isa na Pon isanzwe, igizwe na olt (optique (optique) hamwe na status yo gukwirakwiza.
Itandukaniro riri hagati ya EPON na GPON
GPON yikoresha igabana ryuburebure rusange (WDM) kugirango ushobore kohereza icyarimwe no gukuramo. Mubisanzwe, uwitwara neza 1490nm ya Optique ikoreshwa mugukuramo, mugihe gito cya Optique ya Optique yatoranijwe kugirango ashyiremo. Niba ibimenyetso bya tereviziyo bigomba kwanduzwa, uwatwarwa 1550nm nayo izakoreshwa. Nubwo buri onu ishobora kugera kuri look yo gukuramo 2.488 Gbits / s, GPON ikoresha kandi kugabana igihe kinini (TDMA) kugirango itange igihe runaka kuri buri mukoresha mugihe cyigihe.
Igipimo ntarengwa cyo gukuramo XGPON kigera kuri 10Gits / s, kandi igipimo cyo kohereza nacyo na 2.5GITBt / s. Irakoresha kandi tekinoroji ya WDM, kandi uburebure bwamasoko ya Hejuru na Downstream Caprique Abatwara imyaka 1270nm na 1577nm.
Kubera ubwiyongere bwiyongereye, byinshi kuri orus birashobora kugabanywa ukurikije imiterere imwe ya data, hamwe nintera ntarengwa ya 20km. Nubwo XGPOON itigeze yemezwa cyane, itanga inzira nziza yo kuzamura abakora ibyemezo byiza.
EPON irahuye neza nibindi bipimo bya Ethernet, ntabwo rero bikenewe kugirango uhinduke cyangwa utandukanye mugihe uhujwe nimiyoboro ya ethernet, hamwe numushahara ntarengwa wa 1518 bytes. EPON ntabwo isaba uburyo bwa CSMA / CD muburyo bumwe muri verisiyo zimwe na zimwe za Ethernet. Mubyongeyeho, nkuko byakwirakwije Ethernet nuburyo nyamukuru bwo kwanduza imiyoboro yaho, nta mpamvu yo guhindura protocole ya porotocol mugihe cyo kuzamura umuyoboro wa metropolitan.
Hariho na 10 Gut / s Ethernet verisiyo yagenwe 802.3AV. Umuvuduko nyawo ni 10.3125 Gbits / s. Uburyo bwingenzi ni Gbits 10 Gbits / S Hagarika igiciro, hamwe na hamwe ukoresheje Gbits 10 / s Downlink na 1 Gutha / S Uplink.
Ibisobanuro bya Gbit / s bikoresha uburebure butandukanye kuri fibre, hamwe no kumanura uburebure bwa 1575-1580nm na hejuru yumurongo wa 1260-128000000. Kubwibyo, sisitemu 10 ya git-s hamwe na sisitemu isanzwe ya 1GITT / s irashobora kuba uburebure bwa pasiporo imwe.
Triple Gukina
Ihuriro ry'imiyoboro itatu risobanura ko mu nzira y'ubwihindurize kuva ku gishushanyo mbonera cy'itumanaho, umuyoboro wa televiziyo, hamwe na interineti, hamwe na interineti. Imyitozo ya gatatu ntabwo isobanura guhuza imiyoboro itatu yingenzi, ariko bivuga cyane cyane guhuza ibikorwa byo murwego rwohejuru.
Kwishyira hamwe kw'imiyoboro itatu birakoreshwa cyane mu nzego zitandukanye nk'itunganijwe ry'ubwenge, kurengera ibidukikije mu bidukikije, imirimo ya leta, umutekano wa Leta, n'amazu meza. Mu bihe biri imbere, terefone zigendanwa zishobora kureba TV na Surf interineti, TV irashobora guhamagara kuri terefone na surf interineti, kandi mudasobwa irashobora kandi guhamagara telefoni no kureba TV.
Kwishyira hamwe kwimiyoboro itatu birashobora gusesengurwa muburyo butandukanye nurwego butandukanye, birimo kwishyira hamwe kwikoranabuhanga, kwishyira hamwe mubucuruzi, kwishyira hamwe mubucuruzi, kwishyira hamwe mubucuruzi, kwishyira hamwe kwamafaranga, guhuza uruganda.
Ikoranabuhanga mugari
Ikoranabuhanga ryikoranabuhanga mugari ni fibre nziza itumanaho. Imwe mu ntego zurusobe rwo guhuza ni ugutanga serivisi zunze ubumwe binyuze murusobe. Gutanga serivisi zidafite ishingiro, ni ngombwa kugira urubuga rwurusobe rushobora gushyigikira kohereza serivisi zitandukanye mu bibaya bitandukanye (Meaming) nkamajwi na videwo.
Ibiranga ubwo bucuruzi nibyifuzo byinshi byubucuruzi, ingano nini yamakuru, hamwe nibisabwa byose bya serivisi, kugirango mubisanzwe bisaba umurongo munini cyane mugihe cyo kohereza. Byongeye kandi, ukurikije ubukungu, ikiguzi ntigikwiye kuba hejuru cyane. Muri ubu buryo, ubushobozi bukomeye kandi burambye fibre nziza itumanaho ya optique byabaye amahitamo meza yo kohereza itangazamakuru. Iterambere ryikoranabuhanga mugari, cyane cyane ikoranabuhanga ryiza ryera, ritanga igiteranyo cyagaburiwe, nogutwara, nigiciro gito cyo kohereza amakuru atandukanye yubucuruzi.
Nk'ikoranabuhanga ry'inkingi mu gihe cy'itumanaho ry'ituruka muri iki gihe, Ikoranabuhanga ryiza ryo mu itumanaho riratera imbere ku gipimo cy'imikurire 100 buri myaka 10. Fibre Optic Kwanduza hamwe nubushobozi bukomeye ni urubuga rwiza rwo kohereza "imiyoboro itatu" hamwe nabatwara umubiri nyamukuru wamakuru yamakuru. Ubushobozi bunini bwa fibre Optique Itumanaho ryakoreshejwe cyane mumiyoboro itumanaho, imiyoboro ya mudasobwa, hamwe no gutangaza hamwe na tereviziyo.
