GFH2009 RFoG FTTH Micronode

Nā hiʻohiʻona:

•E hui ana i ka maʻamau SCTE-174-2010.

•Ala i mua 1002/1218MHz RF bandwidth.

•17dBmV RF Hunahu@1550nmRx.

•ʻO ka Burstmode 1610nmTx@+3dBm.

•Loaʻa ka lōʻihi nalu CWDM no OBI manuahi.

ʻO RFoG ʻo ia ka "Radio Frequency over Glass". Hoʻokuʻu ʻia ka maʻamau ʻenehana e SCTE ma ka palapala SCTE-174-2010, e wehewehe ana i ke ʻano burst CATV ala hoʻihoʻi laser e hoʻohuli ana a hoʻohuli i ka wā e loaʻa ai i ka node optical ʻelua nā hōʻailona o ka modem upstream. ʻO nā walaʻau ala hoʻi ka mea nui o ka ʻōnaehana CATV ʻelua ala. Hoʻouna ʻia nā modem uwea āpau a i ʻole nā leo hoʻokele CATV i ka Headend. Ma ka ʻōnaehana RFoG PON, ʻo ka micronode RFoG e pili ana me ka modem uwea hana e hoʻā wale ana i ka wā e pio ana nā micronodes ʻē aʻe. Hoʻokahi wale nō hōʻailona hoʻihoʻi micronode RFoG i CMTS, ʻoi aku ka liʻiliʻi o nā leo ma mua o ka ʻōnaehana CATV ʻelua ala maʻamau.

Ma muli o ka hoʻopaʻa ʻana o nā kaila ma Docsis 3.0 a me Docsis 3.1 ʻōnaehana, e loaʻa kahi pilikia OBI (Optical Beat Interference) ma muli o ʻelua a ʻoi aʻe paha nā laser lōʻihi hawewe e hōʻea ana i hoʻokahi photodiode i ka manawa like. No ka pale ʻana iā OBI, pono e loaʻa nā lōʻihi hawewe laser ʻokoʻa ma RFoG Micronode ma ka ʻōnaehana PON hoʻokahi.

Hāʻawi ʻo RFoG Micronode i nā lawelawe CMTS a me Cable Modem e neʻe ana mai HFC a PON "Fiber i ka home".

Hoʻolālā ʻia ʻo GFH2009 RFoG MicroNode e loaʻa i ka 1550nm hoʻolaha RF a i ʻole IP HD wikiō mai Passive Optical Network (PON) a hoʻouna i nā hōʻailona modem cable upstream ma 1610nm a i ʻole ka lōʻihi o ka nalu CWDM. Kākoʻo ʻo GFH2009 i ka hoʻihoʻi ʻana i ka hōʻailona RF burst modem, e ʻae ana i kahi modem cable e kamaʻilio me CMTS ma ka ʻāpana manawa o TDMA. Hoʻopuka ʻo GFH2009 i nā lawelawe RF interactive bi-directional. Hoʻolālā ʻia ʻo GFH2009 e kākoʻo iā DOCSIS2.0, DOCSIS3.0 a me DOCSIS3.1.
