IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-RFoG isho ukuthi “Imvamisa yomsakazo phezu kwengilazi”.Izinga lobuchwepheshe likhishwa yi-SCTE kudokhumenti i-SCTE-174-2010, echaza imodi yokuqhuma ye-CATV yomzila wokubuyisa i-laser evula futhi ivalwe lapho inodi yokubona yezindlela ezimbili ithola amasignali emodemu yekhebula ekhuphuka nomfula.Imisindo yendlela yokubuya iyinkinga enkulu yesistimu ye-CATV yezindlela ezimbili.Wonke amamodemu ekhebula noma imisindo yetheminali ye-CATV ibuyiselwa ku-Headend.Kuhlelo lwe-RFoG PON, i-micronode ye-RFoG exhuma nemodemu yekhebula elisebenzayo ivula kuphela ngenkathi amanye ama-micronode e-RFoG evaliwe.Kunesignali eyodwa kuphela ye-RFoG micronode yokubuyisela ku-CMTS, imisindo emincane kakhulu kunohlelo oluvamile lwe-CATV lwezindlela ezimbili.

Njengoba iziteshi eziningi ezibophezela ohlelweni lwe-Docsis 3.0 kanye ne-Docsis 3.1, kuzoba nenkinga ye-OBI (Optical Beat Interference) ngenxa yama-lases we-wavelength amabili noma ngaphezulu afika ku-photodiode eyodwa ngesikhathi esisodwa.Ukuze ugweme i-OBI, kufanele kube namaza wamaza e-laser ahlukile ku-RFoG Micronode kusistimu ye-PON efanayo.

I-RFoG Micronode inika amandla i-CMTS kanye nezinsiza zeModemu Yekhebula zisuka ku-HFC ziye ku-PON “I-Fiber iya ekhaya”.

I-GFH2009 RFoG MicroNode iklanyelwe ukwamukela i-RF yokusakaza engu-1550nm noma ividiyo ye-IP HD evela ku-Passive Optical Network (PON) futhi ithumele amasignali emodemu yekhebula ekhuphukayo ku-1610nm noma enye i-wavelength ye-CWDM.I-GFH2009 isekela ukudluliselwa kwemodi yokuqhuma kwesiginali ye-RF, okuvumela imodemu yekhebula eyodwa ukuthi ixhumane ne-CMTS esigabeni sesikhathi se-TDMA.I-GFH2009 ikhipha izinsiza ze-RF ezilandelanayo ezimbili.I-GFH2009 yakhelwe ukusekela i-DOCSIS2.0, DOCSIS3.0 kanye ne-DOCSIS3.1.
