Hano hari miliyoni za DVB-C STBs zikora kuri sisitemu ya CATV HFC. Gusimbuza izi STV zose za DVB-C bisaba amafaranga menshi kandi ntabwo ari ingirakamaro kubakoresha CATV benshi. Hagati aho, bihenze gukoresha modem ya kabili itanga serivise ya interineti hejuru ya sisitemu ya HFC. 1550nm yuzuye sisitemu ya FTTH ni amahitamo ahendutse kuri DVB-C RF na interineti.Imiterere isanzwe ya HFC imiterere ishingiye ku nyenyeri-umuyoboro. Intsinga ya fibre fibre ihujwe neza na numero ya optique (urugeroGWR1200) kuvaGWT35001550nm yohereza kuri headend, kandi buri optique ikorera abafatabuguzi ba CATV babarirwa mu magana hejuru ya kabili ya coaxial.
Ikoranabuhanga rya Greatway ryerekana gushirahoGRT319kure ya OLT kuri optique node ya sisitemu ya HFC kugirango ubike ishoramari rya fibre fibre no gukomeza serivisi zose za DVB-C RF. Tugumisha inyenyeri-1550nm kuri buri optique kandi tumenyekanisha 2.5Gbps cyangwa 10Gbps kuri fibre imwe kuri fibre optique na WDM.
Iyambere ya optique node isimburwa numweGRT319Remote-OLT ahantu hamwe hamwe no gutanga amashanyarazi amwe. Imiyoboro ya coaxial yahoze hamwe ninsinga byasimbujwe ibice bya PLC hamwe ninsinga za FTTH kugirango bipfundikire abafatabuguzi bose.
GRT319Remote OLT yashizweho kugirango isimbuze optique ya HFC, ihindura imiyoboro ya kabili ya coaxial ya metero 100 iheruka muri fibre ya metero 100 iheruka kumurongo wurugo, itanga serivise za interineti DVB-C RF na GPON kubakoresha bose ba CATV. Hamwe n'inzu ya Aluminium idafite amazi,GRT319ifite icyambu kimwe cyinjiza fibre aho amakuru ya 10Gbps na 1550nm CATV RF ituruka kuri Headend na WDM, ikiza ishoramari rya fibre. GRT319 ifite fibre imwe isohoka ihuza muri 20dBm EDFA hamwe nicyambu kimwe GPON OLT, ifasha abafatabuguzi bagera kuri 256 mumaradiyo ya metero 100 ya kabili FTTH. Gukorana naGFH1000-KFTTH CATV yakira, GRT319 Remote OLT ituma DVB-C STB ubucuruzi gusa kubakoresha CATV. Gukorana naGONU1100WFTTH ONU, GRT319 Remote OLT itanga 2.5Gbps kumurongo wa enterineti usibye CATV RF.
Node by node,GRT319Irashobora gufasha CATV MSO guhindura sisitemu imwe ya HFC CATV muburyo bubiri bwa FTTH kuri bije ihendutse.
