EPON (Ethernet Intaneti Yopyapyala)
Ethernet instive network network ndi ukadaulo wa pon potengera Ethernet. Imatengera mfundo yochulukirapo komanso kufalitsa kufalitsa fibeki, kupereka chithandizo chambiri kuposa Ethernet. A Elun Technology amatheradi ndi a Ieee802.3 EFM Gulu Logwira Ntchito. Mu June 2004, gulu la IEEEE802.3efm Ogwira ntchito adatulutsa muyezo wa EPON - IEEEE80.3amu (i) mu 2005.3-2005 Muyeso mu 2005).
Mu muyezo uwu, matekinoloje a Ethernet ndi a Pon amaphatikizidwa, ndi ukadaulo wa pon wogwiritsidwa ntchito pazakuthupi komanso ethernet protocol wogwiritsidwa ntchito pa intaneti wosanjikiza, kugwiritsa ntchito utulomology ya Pon kuti mupatsidwe Ethernet. Chifukwa chake, chimaphatikiza zabwino za ukadaulo wa Pon ndi Teatnet Technology: mtengo wotsika, chiwopsezo champhamvu, chofanizira ndi Ethernet, ethertive, etc.
GPON (PANOIT-MUTURE)
Tekinoloje ndi m'badwo waposachedwa kwambiri wa zowonjezera zophatikizira zophatikizira zopezeka pa itu-tg.984. X Standard, yomwe ili ndi zabwino zambiri monga ma bandwidth apamwamba, okwanira, malo ochulukirapo, komanso mawonekedwe owonjezera ogwiritsa ntchito. Amawonedwa ndi ogwiritsa ntchito ambiri monga ukadaulo wabwino pokwaniritsa Broadband ndikusintha kwathunthu kwa ntchito za intaneti. GPON adafunsidwa koyamba ndi Fsan Bungwe la FSA mu Seputembara 2002. Kutengera izi, itu-t g.984.3 mu Fesoti 2004. Chifukwa chake, banja lokhazikika la GPOON ndi June.
Tekinoloje ya GPON idachokera ku muyeso wa Asan ukadaulo womwe pang'onopang'ono udapangidwa mu 1995, ndipo poni amayimira "ma network openyera" mu Chingerezi. GPONE (Gigabit Cartive Intaneti Yopatsirana) idafunsidwa koyamba ku Fsan Bungwe la FSAN mu Seputembara 2002. Kutengera izi, Itu-THEBERID NDI G.984.3 mu Fesoti 2004. Chifukwa chake, banja lokhazikika la GP.984.3 mu Feth Kapangidwe koyambira kwa zida zochokera ku GPOC Techlogy ndi yofanana ndi pon, yokhala ndi ma cell a Olt (Odn (STU)
Kusiyana pakati pa enin ndi GPON
Gpon imagwiritsa ntchito ma entration am'misikidwe (WDM) kuti athandize kulowa nthawi yomweyo ndikutsitsa. Nthawi zambiri, munthu wonyamula madokotala 1490nm amagwiritsidwa ntchito kutsitsa, pomwe munthu wonyamula ma 1310nm amasankhidwa kuti akweze. Ngati zizindikiro za TV zimafunikira kufalikira, wonyamula ma 1550nm amagwiritsidwanso ntchito. Ngakhale kuti munthu aliyense angakwaniritse kuthamanga kwa 2.488 gbits / s, GPOON kumagwiritsanso ntchito gawo limodzi lolowera (TDMA) kugawa nthawi inayake kwa wogwiritsa ntchito aliyense mu siginecha.
Kutsitsa kwakukulu kotsitsa kwa XGPOn kuli mpaka 10Gbibles / s, ndi kuchuluka kwake ndi 2.5gbit / s. Ikugwiritsanso ntchito ukadaulo wa WDM, ndipo mafunde am'mwambamwamba komanso otsika kwambiri ndi 1270nm ndi 1577nm, motsatana.
Chifukwa cha kuchuluka kwa kufalikira, othani ochulukirapo amatha kugawidwa molingana ndi mtundu womwewo wa data, ndi malo okwanira mpaka 20km. Ngakhale kuti Xgpon sanatengedwe kwambiri, zimapereka njira yabwino yosinthira korona yolumikizirana.
EPONI imagwirizana kwathunthu ndi mfundo zina za Ethernet, kotero palibe chifukwa chotembenuzira kapena kusinthidwa mukalumikizidwa ndi ma network a Ethernet, omwe ali ndi ma byte 1518. EPON safuna njira ya CSMA / CD mu njira zina za Ethernet. Kuphatikiza apo, monga kufala kwa Ethernet ndi njira yayikulu yopita kudera la ma network, palibe chifukwa chosinthira ma network protocolit panthawi yokweza ma metropolitan.
Palinso mtundu wa 10 GBTEET KAINAKHALA ngati 802.3av. Liwiro lenileni ndi 10.3125 GBTS / S. Njira yayikulu ndi ma gbils / s uplink ndi kutsika, ndi ena pogwiritsa ntchito 10 gbitlink ndi 1 GRIVING.
Mtundu wa GRIC / SE imagwiritsa ntchito mawonekedwe osiyanasiyana pa fiber, wokhala ndi mafunde a 1575-15800nm ndi mawonekedwe a 1260-1280nm. Chifukwa chake, dongosolo la 10 GBT / S ndi dongosolo la 1Gbible / S limatha kukhala lofanana ndi mbiya imodzi.
Kuphatikizika katatu kuphatikiza
Kugwirizana kwa maukonde atatu kumatanthauza kuti pokonzekera kusinthika kwa intaneti, wailesi ndi wailesi yakanema. Kuphatikizika katatu sikutanthauza kusintha kwa maulendo atatu a manambala atatu, koma makamaka amatanthauza kuphatikizika kwa ntchito zamabizinesi apamwamba kwambiri.
Kuphatikiza kwa maukonde atatu kumagwiritsidwa ntchito kwambiri m'mitundu yosiyanasiyana monga mayendedwe anzeru, kutetezedwa kwa chilengedwe, ntchito yaboma, chitetezo paboma, ndi nyumba zotetezeka pagulu. M'tsogolo, mafoni a m'manja amatha kuwonera pa intaneti, TV imatha kupanga mafoni ndi kusefukira pa intaneti, ndipo makompyuta amathanso kuyimba foni ndikuwonera TV.
Kuphatikiza kwa maukonde atatuwo kumatha kusanthula mokakamizidwa ndi malingaliro osiyanasiyana, kuphatikiza ukadaulo wa ukadaulo, kuphatikiza kwa mabizinesi, kuphatikiza kwa makampani, komanso netiweki.
Tekinoloje
Thupi lalikulu la ukadaulo wa Broadband ndiukadaulo woyankhulira wa fiber. Chimodzi mwazilinga za ku Connergence Conflonce ndikupereka ntchito zogwirizana kudzera pa netiweki. Kuti mupereke ntchito zosagwirizana, ndikofunikira kukhala ndi nsanja ya network yomwe imatha kuthandizira kufala kwa ma multimedia (kukonzanso media) ntchito monga audio ndi kanema.
Makhalidwe a mabizinesi amenewa ndi bizinesi yayikulu, voliyumu yayikulu ya data, komanso zofunikira zapamwamba, motero nthawi zambiri zimafunikira gulu lalikulu kwambiri pakufalitsa. Kuphatikiza apo, kuchokera ku malingaliro azachuma, mtengo suyenera kukhala wokwera kwambiri. Mwanjira imeneyi, umisiri wapamwamba kwambiri komanso ukadaulo wokhazikika wa fiber wakhala chisankho chabwino kwambiri chofalitsa media. Kukula kwa ukadaulo wa Broadband koloko, kumapereka bandwidth, yabwino kwambiri, komanso mtengo wotsika potumiza chidziwitso zosiyanasiyana bizinesi.
Monga ukadaulo wamapiriki wolumikizirana ndi gawo, ukadaulo wolankhula umayamba kukula nthawi 100 ikukula zaka 10 zilizonse. Chitsamba cha Fiber Optic ndi mphamvu yayikulu ndi njira yabwino yotumizira ya "magawo atatu a intaneti" ndi chonyamulira chachikulu chamtsogolo. Tekisiki yoyankhulidwa bwino kwambiri imagwiritsidwa ntchito kwambiri pafoni yolumikizirana, maukonde apakompyuta, ndi kutumizirana ma network komanso pa TV.
