DOCSIS HANZE PON (D-PON)
Inyandiko hejuru yicyifuzo cya PON (D-PON) itanga igisubizo kuri CATV MSO gutanga serivise za HDTV + Ethernet kubakoresha 3000 FTTH mubaturage bafite intera iri munsi ya 10Km fibre kugera kubiro bikuru. Buri mufatabuguzi azaba afite 60ch + QAM umuyoboro wa HDTV hamwe na 50Mbps ya Broadband ubushobozi. Micronode ya RFoG, CMTS na CWDM nibikoresho byingenzi muriki cyifuzo.
SCTE yatangaje RF hejuru yikirahure (RFoG) isanzwe ya SCTE-174-2010 mumyaka mike ishize, isobanura inzira yo kugaruka inzira ituma modem imwe gusa yohereza amakuru yinyuma hejuru ya fibre fibre kuri CMTS mugihe modem zose zashizwe kumurongo wa TDMA. Hamwe na RFoG, Cable MSO irashobora kwagura serivise ya CMTS / Cable Modem kuva kumurongo wa HFC kugera kuri Fibre kugeza murugo (FTTH). Nibyo bita DOCSIS hejuru ya Passive Optical Network (D-PON). D-PON ishyigikira 1x32 optique itandukanya 20Km ya fibre cyangwa 1x64 optique itandukanya 10Km intera.
Twatangije kandi Docsis 3.0 mini-CMTS ishingiye kuri C-DOCSIS. GmCMTS30 ifite imiyoboro 16ch yamanuka hamwe numuyoboro 4 wo hejuru, ushyigikira docsis 2.0 na modem ya kabili 3.0. Kuri 256QAM, imiyoboro 16 DS ishobora kuba yarasangiye umurongo wa 800Mbps, bivuze ko abafatabuguzi ba modem 256, umuvuduko wa Ethernet ushobora kuba hafi 50Mbps.
Hamwe noguhuza neza kwa CMTS na D-PON, Cable MSO irashobora gutanga serivise za HDTV zihiganwa hamwe na serivise yihuta ya interineti ku giciro cyiza. Hamwe na fibre murugo, sisitemu zose hamwe no kuzamura byoroha cyane.
Muri sisitemu ya Docsis 3.1 cyangwa Docsis 4.0 isaba inzira nyinshi zo kugaruka kumuyoboro uhuza umurongo mugari wa CATV, optique ya hit hitamo (OBI) nikintu kitoroshye muri sisitemu ya PON. Hamwe na CWDM idasubizwa inzira ya laser kumurongo watoranijwe neza, GFH2009 RFoG Micronode itahura OBI kubuntu kubukungu bwingengo yimari, ifite ibyiza byo gutangaza televiziyo ya HD amagana no gusangira amakuru ya 10Gbps ya Ethernet.
Reba D-PON icyifuzo cyo gushushanya hamwe na D-PON ibikoresho byo guhuza igishushanyo.
