Iyo inonzi PON network ine zvikamu zvitatu:OLT, ODN uyeONU.AnOLTmudziyo uri pakati peiyo network topology.Iyo inowana akawanda masevhisi network kumusoro uye masevhisi evazhinji vashandisi pasi kuburikidza neODN.Iyo yakakosha node yekuunganidza sevhisi uye kugovera.OLTpanguva imwe chete inoona akawanda manejimendi manejimendi mabasa akadai sekutonga, manejimendi, kutangira uye zvichingodaro kune mutengi mudziyoONU.OLTzvishandiso ndizvo musimboti wePON network zvese maererano nenzvimbo yayo yetiweki kana network basa.NeMasevhisi akawanda uye akawanda akadai sekuwana Internet, 4K IPTV vhidhiyo, smart home services, madiki uye epakati bhizinesi akatsaurirwa mitsara, IMS izwi, uye mobile backsend inotakurwa paPON network, kudiwa kwebandwidth uye nhanho yekunatsiridza. hutungamiri hunoramba huchiwedzera .Kuvandudzwa kwePON teknolojia uye kushandiswa uye kushanduka kweOLTzvishandiso zvinoita basa rakakosha mukuvandudza mabroadband access network.
Ongororo yePON network mamiriro
(1)OLTkuendesa midziyo
TheOLTmidziyo yevashandi vemumba yakaiswa muna 2006, uye yainyanya kushandiswa kuwana PON + DSL muchikamu chekutanga.Kubva 2009, FTTH yakaiswa pamwero mukuru kweanopfuura makore gumi.Zvinoenderana neiyo slot bandwidth, simba rekuchinja remuchina wese, uye kutsigirwa kwePON board kadhi, kune 2 ~ 3 zvizvarwa zvezvigadzirwa zviri kushanda mune yazvino network.Iyo imwechete slot switching simba remugadziri mukuru wekupusha michina mu ikozvino network kushanda inosvika 40G/ slot, uye ose rutsigiro 10G EPON uye XG-PON1.
(2) PON teknolojia yekuendesa
Nekushandiswa zvishoma nezvishoma kwekutengesa kwe10G PON tekinoroji, makadhi ePON akagadziridzwa neOLTzvishandiso zviri mumambure azvino zvakakamurwa kuva mhando ina: EPON, GPON, 10G EPON uye XG-PON, pakati peiyo EPON neGPON ndiyo inonyanya kukosha.
Pasi pekusimudzirwa kwekuvandudzwa kweEPON zviyero neChina Telecom neChina Unicom, EPON inoshanda mumusha inotengeswa makore maviri kusvika matatu apfuura kupfuura GPON.Gore ra2013 risati rasvika, kuvakwa kwacho kwaitongwa neEPON, uyezve, nekuda kwezvakanaka zveGPON mubandwidth, zvishoma nezvishoma yakatora chinzvimbo chikuru mu.OLTkuvaka.Kubva pakuona kweiyo ikozvino network stock deployment, iyoOLTmidziyo yeChina Unicom neChina Mobile inonyanya kuve GPON, ukuwo China Telecom iri kunyanya EPON.
10G PON Construction yakatanga kutenderera 2015. Sezvo mutengo we 10G optical module unogara wakakwirira, mutengo we10G PON ONT inenge 5 nguva yeiyo iripo EPON / GPON terminals.Munharaunda yazvino iyo vashandisi vanowanzopa materminals kune vatengi, uye kudiwa kwebhizinesi kuri pasi pe100 Mbit / s, vese vashandisi vakuru vanongwarira nezve kutumirwa uye kushandiswa kwe10G PON.Parizvino, nzira yekuvaka ye10G PON inonyanya kushandiswa mu10 GPON + LAN uye FTTH deployment.10 GPON + LAN inonyanya kushandura sero iripo LAN, network uye PON + LAN network.Kune rumwe rutivi, inogadzirisa dambudziko rekushaya kukwana bandwidth inokonzerwa nehuwandu hwehuwandu hwevashandisi vekuwana;kune rumwe rutivi, sezvo vashandisi vakawanda vachigovana mutengo we optical module muMDU, iyo yose mutengo inowedzera zvishoma kana ichienzaniswa nePON + LAN, saka ine yakakura-scale application, uye zvose 10G PON uye XG-PON zvinogamuchirwa.Kuvakwa kwe10G PON FTTH inonyanya kuve chirongwa chekuyedza chinoitwa nevashandisi vakasiyana.Chinangwa chikuru ndechekushambadza uye kuona zvigadzirwa zve10G PON FTTH.
Iri pamusoro ndiyo tsananguro yechimiro chese chePON network.Zvigadzirwa zvetiweki zveShenzhen HDV Photoelectronic Technology Co., Ltd. ese midziyo inogadzirwa yakatenderedza PON network, kusanganisira.ONUseries/OLTseries / optical module series / transceiver series uye zvichingodaro.
