DOCSIS PON PON (D-PON)
Docsis pamusoro pePON (D-PON) chikumbiro chinopa mhinduro kuCATV MSO kuti ipe HDTV + Ethernet masevhisi kune vangangosvika zviuru zvitatu FTTH vanonyoresa munharaunda isingasviki 10Km fiber chinhambwe kuenda kuhofisi yemusoro.Mumwe nemumwe anonyoresa achava ne60ch+ QAM chiteshi HDTV zvirimo uye 50Mbps Broadband kugona.RFoG micronode, CMTS uye CWDM ndiwo midziyo mikuru muchikumbiro ichi.
SCTE yakazivisa RF pamusoro peGlass (RFoG) yakajairwa SCTE-174-2010 makore mashoma apfuura, ichitsanangura nzira yekudzoka yakaputika iyo inobvumira chete tambo modem kutumira reverse data pamusoro pefiber tambo kuCMTS kana ese matambo modem akaiswa paTDMA modhi.NeRFoG, Cable MSO inogona kuwedzera CMTS/Cable Modem sevhisi kubva kuHFC network kuenda kuFiber kuenda kumba (FTTH) network.Iyi ndiyo inonzi DOCSIS pamusoro pePassive Optical Network (D-PON).D-PON inotsigira 1x32 optical splitter pa20Km faibha kure kana 1x64 optical splitter pa10Km faibha kure.
Takaunza zvakare Docsis 3.0 mini-CMTS yakavakirwa paC-DOCSIS chiyero.GmCMTS30 ine 16ch nzira dzekudzika uye 4 nzira dzekukwira, inotsigira docsis 2.0 uye docsis 3.0 cable modem.Pa256QAM, 16 DS nzira dzinogona kunge dzakagovana 800Mbps bandwidth, zvinoreva kune 256 cable modem vanyoreri, iyo yakachena Ethernet kumhanya inogona kuita 50Mbps.
Iine musanganiswa wakakwana weCMTS uye D-PON, Cable MSO inogona kupa inokwikwidza HDTV uye High Speed internet masevhisi pamutengo unokwanisika.Nefiber kumba, zvese zvekuchengetedza system uye kukwidziridza zvinova nyore.
Muhurongwa hweDocsis 3.1 kana Docsis 4.0 iyo inokumbira imwe nzira yekudzoka nzira yekubatanidza pazasi CATV bandwidth, optical beat interference (OBI) chinhu chinonyanya kunetsa muPON system.Iine yakavakirwa-mukati isina kutonhorera CWDM yekudzoka nzira laser pane yakasarudzwa optical hwindo, GFH2009 RFoG Micronode inoona OBI yemahara kudiwa pabhajeti rehupfumi, ine zvakanakira kutepfenyura mazana eHD TV uye kugovera 10Gbps Ethernet data.
Ona D-PON chirevo chetiweki kudhirowa uye D-PON headend michina yekubatanidza dhizaini.
