GFH2009 RFoG FTTH Micronode
Sharaxaada Alaabta
RFoG macnaheedu waa "Soo noqnoqoshada Raadiyaha ee Muraayada". Heerarka farsamada waxaa sii daayay SCTE dukumeentiga SCTE-174-2010, kaas oo qeexaya qaabka dilaaca CATV dariiqa soo laabashada leysarka shid iyo deminta marka qanjirada laba-geesoodka ah ay hesho calaamadaha modem-ka kor u kaca. Dhawaqa dariiqa soo celinta ayaa ah welwelka ugu weyn ee nidaamka CATV-ga laba-geesoodka ah. Dhammaan modemamka fiilooyinka ama dhawaaqyada terminalka CATV ayaa dib loogu soo celiyaa Headend. Nidaamka RFoG PON, RFoG micronode ku xidha modem fiilada shaqada ayaa shid kaliya halka micronodes-ka RFoG ee kale ay dansan yihiin. Waxaa jira hal calaamad oo ah RFoG micronode soo celinta CMTS, dhawaaq aad uga yar marka loo eego nidaamka CATV ee labada-jid ee caadiga ah.
Maaddaama kanaalo badan oo ku xidhan Docsis 3.0 iyo Docsis 3.1 nidaamka, waxaa jiri doona arrin OBI (Faragelinta garaaca indhaha) taasoo ay ugu wacan tahay laba ama in ka badan oo leysarka mawjadaha dhererka ah oo imanaya hal photodiode isku mar. Si looga fogaado OBI, waa in ay jiraan mowjadaha dhererka leysarka ee RFoG Micronode ee isla nidaamka PON.
RFoG Micronode waxa ay awood u siisaa adeegyada CMTS iyo Cable Modem in ay ka guuraan HFC una guuraan PON "Fiber to the home".
GFH2009 RFoG MicroNode waxaa loogu talagalay inay ka hesho 1550nm baahinta RF ama IP HD fiidyaha Shabakadda Shabakadda Aragtida ee Passive Optical Network (PON) oo u soo dirto kor u kaca calaamadaha modemka fiilada ee 1610nm ama hirarka CWDM kale. GFH2009 waxa ay taageertaa soo celinta signalka RF dilaaca habka gudbinta, taas oo u ogolaanaysa hal modem oo xadhig ah in uu kula xidhiidho CMTS wakhtiga qaybta TDMA. GFH2009 waxay soo saartaa adeegyada RF laba jiho ee is-dhexgalka. GFH2009 waxaa loogu talagalay in lagu taageero DOCSIS2.0, DOCSIS3.0 iyo DOCSIS3.1.
