IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-RFoG ithetha "iRadio Frequency phezu kweGlasi". Umgangatho wobugcisa ukhutshwa yi-SCTE kuxwebhu lwe-SCTE-174-2010, oluchaza imowudi yokuqhuma i-CATV yendlela yokubuyisela i-laser evulayo kwaye ivaliwe xa i-node ye-optical-way-optical node ifumana i-modem ye-cable ye-modem phezulu. Ingxolo yendlela yokubuya yeyona nto iphambili yenkqubo yeCATV yeendlela ezimbini. Zonke iimodem zentambo okanye ingxolo yetheminali yeCATV ithunyelwa emva kwi-Headend. Kwinkqubo ye-RPoG ye-PON, i-micronode ye-RFoG edibanisa ne-modem yentambo yokusebenza ivula kuphela ngelixa ezinye ii-micronodes ze-RFoG zivaliwe. Inye kuphela isignali ye-RFoG micronode yokubuyisela kwi-CMTS, ingxolo encinci kunenkqubo yeCATV yeendlela ezimbini eziqhelekileyo.

Ekubeni amajelo amaninzi adibanisa kwi-Docsis 3.0 kunye ne-Docsis 3.1 inkqubo, kuya kubakho umba we-OBI (Optical Beat Interference) ngenxa yee-lases ezimbini okanye ngaphezulu ezifanayo ze-wavelength ezifika kwi-photodiode enye ngexesha elinye. Ukuze ugweme i-OBI, kufuneka kubekho i-laser wavelengths eyahlukileyo kwi-RFoG Micronode kwinkqubo efanayo ye-PON.

I-RFoG Micronode yenza ukuba i-CMTS kunye neenkonzo zeModem yeCable zifuduke ukusuka kwi-HFC ukuya kwi-PON "I-Fiber ukuya ekhaya".

I-GFH2009 RFoG MicroNode yenzelwe ukufumana i-1550nm yosasazo ye-RF okanye i-IP HD ividiyo esuka kwi-Passive Optical Network (PON) kwaye ithumele imiqondiso yemodem yentambo ephezulu kwi-1610nm okanye enye i-wavelength ye-CWDM. I-GFH2009 ixhasa ukuhanjiswa kwemowudi yokuqhuma kwe-RF, ivumela imodem yentambo enye ukuba inxibelelane ne-CMTS ngexesha le-TDMA. Iziphumo ze-GFH2009 zeenkonzo zeRF ezisebenza ngeendlela ezimbini. I-GFH2009 yenzelwe ukuxhasa i-DOCSIS2.0, i-DOCSIS3.0 kunye ne-DOCSIS3.1.
