GRT319 Akutali OLT ya HFC mpaka FTTH

GRT319 Remote OLT idapangidwa kuti ilowe m'malo mwa HFC Optical node, kutembenuza maukonde omaliza a 100 metres coaxial cable kukhala ma fiber omaliza a 100 mita kupita pa netiweki yakunyumba, ndikumapereka ntchito zonse za intaneti za DVB-C RF ndi GPON kwa onse olembetsa CATV. Ndi nyumba ya Aluminium yopanda madzi, GRT319 ili ndi doko limodzi lolowera ulusi pomwe data ya 10Gbps ndi 1550nm CATV RF zimachokera mwachindunji ku Headend ndi WDM, kupulumutsa ndalama zama fiber. GRT319 ili ndi fiber imodzi yomwe imaphatikizapo 20dBm EDFA ndi doko limodzi la GPON OLT, zothandizira olembetsa okwana 256 mu utali wa 100 mita FTTH chingwe. Kugwira ntchito ndi GFH1000 FTTH CATV wolandila, GRT319 Remote OLT imasunga DVB-C STB yokha bizinesi kwa olembetsa a CATV. Kugwira ntchito ndi GONU1100W FTTH ONU, GRT319 Remote OLT imapereka intaneti ya 2.5Gbps pambali pa CATV RF.

Node ndi mfundo, GRT319 ikhoza kuthandiza CATV MSO kutembenuza njira imodzi ya HFC CATV kukhala njira ziwiri za FTTH system sitepe ndi sitepe pa bajeti yotsika mtengo.

Pali mamiliyoni a ma DVB-C STB omwe akugwira ntchito pamakina amakono a CATV. Tizisunga pamene tikuyambitsa ntchito zambiri za intaneti. OLT yakutali imakhala yabwinoko pamene HFC kupita ku FTTH. 

Timasunga 1550nm nyenyezi-network ku node iliyonse ya kuwala ndikuyambitsa 10Gbps pa fiber yomweyi ku node ya kuwala ndi WDM.

Node yakale ya Optical imasinthidwa ndi Remote-OLT imodzi pamalo omwewo komanso magetsi omwewo.

Zigawo zakale za coaxial ndi zingwe zimasinthidwa ndi ziboda za PLC ndi zingwe za FTTH kuphimba onse olembetsa.

OLT yakutali imathandizira 1 fiber input ndi 1 fiber output.

Chingwe chotulutsa chimakhala ndi siginecha ya 20dBm 1550nm ndi GPON OLT imodzi kwa olembetsa 256. 

Panyumba iliyonse ya FTTH, pali zosankha za TV zokha kapena TV + Internet terminal.
