FA'ATA'IGA I LE PON (D-PON)
Docsis i luga o le PON (D-PON) talosaga e maua ai le fofo mo le CATV MSO e ofoina atu auaunaga HDTV + Ethernet i le tusa ma le 3000 FTTH tagata fai saofaga i totonu o le nuu e itiiti ifo i le 10Km fiber mamao i le ofisa ulu. O le a maua e le au fai saofaga le 60ch+ QAM channel HDTV contents ma le 50Mbps broadband capability. RFoG micronode, CMTS ma CWDM o meafaigaluega autu i lenei talosaga.
SCTE faasilasila RF i luga o le tioata (RFoG) tulaga SCTE-174-2010 i nai tausaga talu ai, faʻamalamalamaina le auala toe foʻi paʻu auala e mafai ai na o le tasi modem uaea auina atu faʻamatalaga i luga o le fiber cable i CMTS pe a seti uma modems cable i le TDMA mode. Faatasi ai ma le RFoG, Cable MSO e mafai ona faʻalauteleina le CMTS / Cable Modem service mai le HFC network i Fiber i le fale (FTTH) network. Ole mea lea ua ta'ua ole DOCSIS ile Passive Optical Network (D-PON). D-PON lagolago 1x32 optical splitter i 20Km fiber mamao po 1x64 optical splitter i 10Km fiber mamao.
Na matou faʻalauiloaina foʻi Docsis 3.0 mini-CMTS faʻavae ile C-DOCSIS tulaga. GmCMTS30 ei ai 16ch i lalo alavai ma 4 upstreaming auala, lea e lagolagoina docsis 2.0 ma docsis 3.0 cable modems. I le 256QAM, 16 DS channels atonu na faʻasoa 800Mbps bandwidth, o lona uiga i le 256 cable modem subscribers, o le saoasaoa Ethernet mama e mafai ona tusa ma le 50Mbps.
Faatasi ai ma le tuufaatasiga atoatoa o le CMTS ma le D-PON, Cable MSO e mafai ona ofoina atu auaunaga faatauva HDTV ma High Speed initaneti i tau taugofie. Faatasi ai ma fiber i le fale, o mea uma e faʻaleleia ma faʻaleleia atili e sili atu ona faigofie.
I le faiga o le Docsis 3.1 poʻo le Docsis 4.0 lea e manaʻomia ai le tele o fesoʻotaʻiga auala e toe foʻi ai i lalo ole bandwidth CATV, o le faʻalavelave faʻalavelave mataʻutia (OBI) o se mea e sili atu ona luitauina i le PON system. Faatasi ai ma le fausia-i le CWDM toe foi mai leisa i le faamalama opitika filifilia, GFH2009 RFoG Micronode iloa OBI manaoga saoloto i se paketi tau tamaoaiga, maua le lelei o le faasalalauina o le faitau selau o TV HD ma faasoa 10Gbps Ethernet faamatalaga.
Va'ai D-PON tusi talosaga feso'ota'iga feso'ota'iga ma D-PON uluga meafaigaluega feso'ota'iga ata.
