DOCSIS OVER PON (D-PON)
Docsis over PON (D-PON) pempho limapereka yankho la CATV MSO kuti ipereke ntchito za HDTV + Ethernet kwa olembetsa pafupifupi 3000 FTTH mdera losakwana 10Km fiber mtunda wopita ku ofesi yakumutu. Wolembetsa aliyense azikhala ndi 60ch+ QAM chaneli HDTV komanso kuthekera kwa Broadband 50Mbps. RFoG micronode, CMTS ndi CWDM ndi zida zazikulu mumalingaliro awa.
SCTE inalengeza RF pa Glass (RFoG) standard SCTE-174-2010 zaka zingapo zapitazo, kufotokozera njira yobwereranso yomwe imalola modemu imodzi yokha kutumiza deta yobwerera pa chingwe cha fiber ku CMTS pamene ma modemu onse a chingwe aikidwa pa TDMA mode. Ndi RFoG, Cable MSO imatha kukulitsa ntchito ya CMTS/Cable Modem kuchokera pa netiweki ya HFC kupita ku Fiber kupita ku netiweki yakunyumba (FTTH). Izi ndi zomwe zimatchedwa DOCSIS over Passive Optical Network (D-PON). D-PON imathandizira 1x32 Optical splitter pa 20Km CHIKWANGWANI mtunda kapena 1x64 kuwala splitter pa 10Km CHIKWANGWANI mtunda.
Tidayambitsanso Docsis 3.0 mini-CMTS kutengera mulingo wa C-DOCSIS. GmCMTS30 ili ndi 16ch njira zotsikira pansi ndi mayendedwe 4 okwera, omwe amathandizira ma docsis 2.0 ndi ma modemu a chingwe cha docsis 3.0. Pa 256QAM, mayendedwe 16 a DS mwina adagawana 800Mbps bandwidth, zomwe zikutanthauza kuti kwa olembetsa a 256 cable modem, liwiro loyera la Ethernet litha kukhala pafupifupi 50Mbps.
Ndi kuphatikiza kwabwino kwa CMTS ndi D-PON, Cable MSO imatha kupereka mpikisano wa HDTV ndi ntchito za intaneti za High Speed pamtengo wotsika mtengo. Ndi fiber kunyumba, kukonza makina onse ndi kukweza kumakhala kosavuta.
M'dongosolo la Docsis 3.1 kapena Docsis 4.0 lomwe limapempha kulumikizana kwa njira yobwereranso pa bandwidth yotsika ya CATV, kusokoneza kwa optical beat (OBI) ndichinthu chovuta kwambiri mu dongosolo la PON. Ndi makina opangidwa ndi CWDM osasunthika obwerera pawindo losankhidwa, GFH2009 RFoG Micronode amazindikira zofuna zaulere za OBI pa bajeti yachuma, pokhala ndi ubwino wofalitsa mazana a HD TV ndikugawana deta ya 10Gbps Ethernet.
Onani zojambula zapaintaneti za D-PON ndi zojambula zolumikizira zida za D-PON.
