GFH2009 RFoG FTTH Micronode
Nkọwa ngwaahịa
RFoG pụtara "Ugboro redio karịrị iko".The teknuzu ọkọlọtọ wepụtara site SCTE na akwụkwọ SCTE-174-2010, nke na-akọwa na mgbawa mode CATV nloghachi ụzọ laser na-atụgharị na gbanyụọ mgbe ụzọ abụọ ngwa anya ọnụ na-enweta USB modem upstream akara.Mkpọtụ ụzọ nloghachi bụ isi ihe na-akpatara usoro CATV ụzọ abụọ.Modem USB niile ma ọ bụ ụda ọnụ CATV na-ezigaghachi na isi okwu.Na sistemụ RFoG PON, RFoG micronode na-ejikọ ya na modem USB na-arụ ọrụ na-agbanye naanị mgbe micronodes RFoG ndị ọzọ na-agbanyụ.Enwere naanị otu RFoG micronode mgbama nloghachi na CMTS, mkpọtụ dị obere karịa sistemụ CATV ụzọ abụọ oge niile.
Ebe ọ bụ na ọwa ndị ọzọ na-ejikọta na Docsis 3.0 na Docsis 3.1 usoro, a ga-enwe okwu OBI (Optical Beat Interference) n'ihi na abụọ ma ọ bụ karịa otu laser wavelength na-abata n'otu photodiode n'otu oge.Iji zere OBI, a ga-enwerịrị ogologo ikuku laser dị iche iche na RFoG Micronode n'otu sistemu PON.
RFoG Micronode na-enyere CMTS na Cable Modem ọrụ ịkwaga na HFC gaa PON "Fiber gaa n'ụlọ".
Emebere GFH2009 RFoG MicroNode ka ọ nata 1550nm mgbasa ozi RF ma ọ bụ IP HD vidiyo sitere na Passive Optical Network (PON) wee zipu akara modem eriri USB na 1610nm ma ọ bụ ogologo CWDM ọzọ.GFH2009 na-akwado nnyefe mgbama RF nloghachi, na-enye ohere ka otu modem USB jikọọ na CMTS na mpaghara oge nke TDMA.GFH2009 na-ewepụta ọrụ RF mmekọrịta mmekọrịta bi-directional.Emebere GFH2009 iji kwado DOCSIS2.0, DOCSIS3.0 na DOCSIS3.1.
