GFH2009 RFoG FTTH Micronode
Ibisobanuro ku bicuruzwa
RFoG bisobanura “Radio Frequency hejuru y'Ibirahure”.Igipimo cya tekiniki cyarekuwe na SCTE mu nyandiko SCTE-174-2010, isobanura uburyo bwaturika CATV yo kugaruka inzira ya laser ikingura kandi ikazimya mugihe inzira ebyiri-optique node yakiriye kabili modem yo hejuru.Garuka inzira urusaku nizo mpungenge nyamukuru zuburyo bubiri bwa sisitemu ya CATV.Imiyoboro ya kabili yose cyangwa urusaku rwa CATV rwoherejwe gusubira kuri Headend.Muri sisitemu ya RFoG PON, micronode ya RFoG ihuza na moderi ikora ya kabili ikora gusa mugihe izindi micronode ya RFoG yazimye.Hariho ikimenyetso kimwe gusa cya RFoG micronode yo gusubiza CMTS, urusaku ruto cyane ugereranije na sisitemu ya CATV isanzwe.
Kubera ko imiyoboro myinshi ihuza sisitemu ya Docsis 3.0 na Docsis 3.1, hashobora kubaho ikibazo cya OBI (Optical Beat Interference) kubera lazeri ebyiri cyangwa nyinshi zingana na lazeri igera kuri fotodi imwe icyarimwe.Kugira ngo wirinde OBI, hagomba kubaho uburebure butandukanye bwa laser kuri RFoG Micronode muri sisitemu imwe ya PON.
RFoG Micronode ituma serivisi za CMTS na Cable Modem ziva muri HFC zerekeza PON “Fibre to home”.
GFH2009 RFoG MicroNode yagenewe kwakira 1550nm yerekana amashusho ya RF cyangwa IP HD ivuye muri Passive Optical Network (PON) no kohereza ibimenyetso byerekana modem ya modem kuri 1610nm cyangwa ubundi burebure bwa CWDM.GFH2009 ishyigikira kugaruka kwa signal ya RF iturika uburyo bwo kohereza, kwemerera modem imwe ya kabili kuvugana na CMTS mugice cyigihe cya TDMA.GFH2009 isohora bi-icyerekezo cya interineti serivisi za RF.GFH2009 yagenewe gushyigikira DOCSIS2.0, DOCSIS3.0 na DOCSIS3.1.
Ibindi biranga:
• Amazu yuzuye ya Aluminium.
• 1002 / 1218MHz inzira igana imbere umurongo wa RF.
• 17dBmV RF ibisohoka kuri FTTH.
• ALC ikora neza -7dBm ~ + 1dBm optique yinjiza.
• 5 ~ 42MHz / 85MHz / 204MHz garuka umurongo wa RF.
• Hindura RF hejuru ya 1310nm cyangwa 1610nm laser ya DFB ikora muburyo buturika.
• Ikiguzi cyiza CWDM igaruka inzira laser inzira ya OBI kubuntu.
• LED yerekana imbere hanyuma usubize ibikorwa byakazi.
• 6KV Kurinda.
• 12V DC imbaraga ku cyambu cya RF.
