GFH2009 RFoG FTTH Micronode
Tlhaloso ea Sehlahisoa
RFoG e bolela "Radio Frequency over Glass".Tekanyetso ea tekheniki e lokollotsoe ke SCTE tokomaneng ea SCTE-174-2010, e hlalosang mokhoa oa ho phatloha oa mokhoa oa ho khutlisa oa CATV o bulela le ho tima ha node ea optical ea litsela tse peli e amohela matšoao a modem a holimo.Melumo ea tsela ea ho khutla ke eona ntho e ka sehloohong e amehang ka mekhoa e 'meli ea tsamaiso ea CATV.Li-modem tsohle tsa cable kapa lerata la terminal la CATV li khutlisetsoa ho Headend.Ho sistimi ea RFoG PON, micronode ea RFoG e hokahantsoeng le modem ea cable e sebetsang e bulela feela ha li-micronode tse ling tsa RFoG li koetsoe.Ho na le lets'oao le le leng feela la ho khutla la RFoG micronode ho CMTS, lerata le fokolang ho feta mokhoa o tloaelehileng oa litsela tse peli oa CATV.
Kaha liteishene tse ngata li tlamahane ho sistimi ea Docsis 3.0 le Docsis 3.1, ho ne ho tla ba le taba ea OBI (Optical Beat Interference) ka lebaka la li-lasers tse peli kapa ho feta tse tšoanang tsa wavelength tse fihlang photodiode e le 'ngoe ka nako e le' ngoe.Ho qoba OBI, ho tlameha ho be le laser wavelengths e fapaneng ho RFoG Micronode tsamaisong e tšoanang ea PON.
RFoG Micronode e nolofalletsa litšebeletso tsa CMTS le Cable Modem ho tloha HFC ho ea PON "Fiber ho ea lapeng".
GFH2009 RFoG MicroNode e etselitsoe ho amohela 1550nm kgaso RF kapa IP HD video ho tswa ho Passive Optical Network (PON) le ho romela matshwao a modem a cable a hodimo ho 1610nm kapa leqhubu le leng la CWDM.GFH2009 e ts'ehetsa phetiso ea mokhoa oa ho khutla oa RF, e lumellang modem ea thapo e le 'ngoe ho buisana le CMTS karolong ea nako ea TDMA.GFH2009 e fana ka litšebeletso tsa RF tse sebetsanang le mahlakore a mabeli.GFH2009 e etselitsoe ho tšehetsa DOCSIS2.0, DOCSIS3.0 le DOCSIS3.1.
Likarolo tse ling:
• Compact Aluminium Housing.

• 17dBmV RF tlhahiso bakeng sa FTTH.
• ALC e sebetsa hantle ho -7dBm~+1dBm optical input.
• 5~42MHz/85MHz/204MHz khutlisetsa RF bandwidth.
• Reverse RF holim'a 1310nm kapa 1610nm DFB laser e sebetsang ka mokhoa oa ho phatloha.
• Khetho ea laser e sebetsang ea CWDM ea ho khutla bakeng sa OBI mahala.
• Pontšo ea LED pele le ho khutlisa boemo ba ho sebetsa ba optical.
• Tšireletso ea 6KV Surge.
• Motlakase oa 12V DC boema-kepeng ba RF.
