Nekutumirwa uye kuita kweiyo optical shanduko yebroadband network, mhando yetiweki inovandudzwa, mwero wekutadza unodzikiswa, uye kunakidza kwemushandisi kunowedzerwa.Parizvino, kuumbwa kwebroadband access network inotongwa neFTTH uye inowedzerwa nePON + LAN.Kana remangwana Broadband yekuwana network ikatora tekinoroji yePON yekubatanidza, haingogone kupa ruzivo rwepamusoro-soro rwemushandisi, asi zvakare kuderedza mutengo wekushanda kwebhizinesi nekuvandudza mabhenefiti ehupfumi.Tevere, chinyorwa ichi chichaita kurudziro yekuvandudza tekinoroji uye kutumira kwe10G PON muchiedza chezvinodiwa zvebhizinesi.
Chii chinonzi PON network
PON network ineOLT, 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 zviri pamwoyo wePON network, zvese maererano nenzvimbo yavo yetiweki uye kugona kwavo network.Sezvo masevhisi akawanda uye akawanda akadai sekuwana Internet, 4K IPTV vhidhiyo, smart home services, madiki uye epakati bhizinesi mitsara yakavanzika, IMS izwi, uye mobile backsend inotakurwa paPON network, kudiwa kwebandwidth uye dhigirii rekunatsiridza. manejimendi anoramba achiwedzera.Kuvandudzwa kwePON tekinoroji uye deployment evolution yeOLTmidziyo inoita basa rakakosha mukuvandudzwa kwebroadband access network..
PON network mamiriro ekuongorora
(1)OLTkuendesa midziyo
TheOLTmidziyo yevashandi vemumba yakatanga kuiswa muna 2006, uye yainyanya kushandiswa kuwana PON + DSL munhanho yekutanga.Pave nemakore anopfuura 10 kubvira FTTH yakatanga kushandiswa pamwero mukuru muna 2009. Maererano ne slot bandwidth, general switching capability, uye PON board support, kune 2-3 zvizvarwa zvezvigadzirwa zvinomhanya pane network mhenyu.Pane network mhenyu, simba rekuchinja reimwe slot yechibatiso chikuru chinosvika 40 Gbit/s uye inotsigira gumi Gbit/s EPON uye XG-PON1.
(2) PON teknolojia yekuendesa
Iine tekinoroji inotengeswa zvishoma nezvishoma 10G PON tekinoroji, maPON mabhodhi akagadziridzwaOLTmidziyo iri mumambure mhenyu yakakamurwa kuita EPON, GPON, 10G EPON uye XG-PON, ayo EPON neGPON ndiwo akanyanya.Pasi pekusimudzirwa kweChina Telecom neChina Unicom kuvandudza chiyero cheEPON, kushandiswa kwekutengesa kweEPON nevashandi vepamba kwaive makore anenge 2-3 apfuura kupfuura GPON.Pamberi pe 2013, kuvakwa kwaitungamirirwa neEPON, uye gare gare, nekuda kwezvakanaka. yeGPON mubandwidth, zvishoma nezvishoma yakatonga kuvakwa kweOLT.Kubva pamaonero eiyo iripo network deployment, China Unicom uye China Mobile'sOLTmidziyo inonyanya GPON, uye China Telecom inonyanya EPON.
Kuvakwa kwe10G PON kwakatanga munenge muna 2015. Pamusana pemutengo wepamusoro we10G optical modules, mutengo we10G PON ONT inenge yakapetwa kashanu pane EPON / GPON terminals iripo.Munharaunda yazvino iyo iyo terminal inowanzopihwa nemushandisi kune mutengi, uye sevhisi inodiwa iri pazasi pe100Mbit/s, makuru maoperator anongwarira nezve kutumirwa kwe10G PON application.Parizvino, nzira yekuvaka ye10G PON inonyanya kushandiswa mu10G PON + LAN uye FTTH deployment.10G PON+ LAN inonyanya kushandurwa kweiyo iripo cell LAN network uye PON+ LAN network.Kune rumwe rutivi, gadzirisa kushomeka kwebandwidth kunokonzerwa nehuwandu hwehuwandu hwevashandisi vekuwana;Nekune rimwe divi, nekuti vashandisi vazhinji vanogovana mutengo weOptical modules muMDU, mutengo wakazara hauwedzere zvakanyanya kana uchienzaniswa nePON + LAN network, saka yakashandiswa pachiyero, uye nehunyanzvi 10G PON uye XG-PON inoshandiswa. .Kuvakwa kwe10G PON FTTH kunonyanya kuita mutyairi wegigabit wepamba anoitwa nevashandisi vakasiyana, uye chinangwa chikuru ndechekushambadza uye kuona zvigadzirwa zve10G PON FTTH.
Inenge 10G (gumi gigabit) Ethernet tekinoroji uye mashandisiro ndiwo ari pamusoro apa ruzivo mapoinzi, nezveOLTmidziyo yakataurwa pamusoro apa muShenzhen HDV Phoelectron Technology Ltd. ndeyemhando yepamusoro yezvigadzirwa zvekutaurirana, se:OLTchinja, GPONOLT, EPONOLT, chiedza KatsiOLT, nezvimwewo, zviri pamusoroOLTmidziyo inogona kushandiswa munzvimbo dzakasiyana siyana, kune zvakasiyana zvinodiwa zvevashandisi kupa mamwe sarudzo, kugamuchirwa kuti uuye kuzonzwisisa, isu tichapa yakanakisa mhando sevhisi.
