Aia nā miliona o nā DVB-C STB e hana nei ma ka ʻōnaehana CATV HFC o kēia manawa. ʻO ka hoʻololi ʻana i kēia mau DVB-C STB he nui ke kālā a ʻaʻole kūpono i ka hapa nui o nā mea hoʻohana CATV. I kēia manawa, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka modem cable e hāʻawi ana i ka lawelawe pūnaewele ma luna o ka ʻōnaehana HFC. ʻO ka ʻōnaehana 1550nm overlay FTTH kahi koho kūpono no ka DVB-C RF a me ka Pūnaewele.Hoʻokumu ʻia ka ʻōnaehana HFC maʻamau i ka pūnaewele hōkū. Hoʻopili pololei ʻia nā kaula fiber Trunk i kekahi mau nodes optical (egGWR1200) maiGWT35001550nm transmitter ma ke poʻo, a lawelawe kēlā me kēia node optical i nā haneli o nā mea kākau inoa CATV ma luna o ke kaula coaxial.
Manaʻo ʻo Greatway Technology e hoʻokomoGRT319OLT mamao ma ka wahi node optical o ka ʻōnaehana HFC no ka mālama ʻana i nā lawelawe DVB-C RF āpau. Mālama mākou i ka 1550nm star-network i kēlā me kēia node optical a hoʻokomo i ka 2.5Gbps a i ʻole 10Gbps ma ka fiber like i ka fiber node optical e WDM.
Hoʻololi ʻia ka node optical mua i hoʻokahiGRT319mamao-OLT ma ka wahi like a me ka lako mana like. Hoʻololi ʻia nā mea hoʻokaʻawale coaxial mua a me nā kaula e nā PLC splitters a me nā kaula FTTH e uhi i nā mea kākau inoa āpau.
GRT319Hoʻolālā ʻia ʻo OLT mamao e hoʻololi i ka node optical HFC, e hoʻohuli ana i ka 100 mika coaxial uea hoʻolaha pūnaewele hope loa i ka fiber 100 mika hope loa i ka pūnaewele home, e hāʻawi ana i nā lawelawe pūnaewele DVB-C RF a me GPON i nā mea kākau inoa CATV a pau. Me ka hale pale wai alumini,GRT319Loaʻa i hoʻokahi awa hoʻokomo fiber kahi 10Gbps ʻikepili a me 1550nm CATV RF pololei mai Headend e WDM, e mālama ana i ka hoʻopukapuka ʻana o ka fiber. Loaʻa iā GRT319 hoʻokahi fiber output e hoʻohui ana i ka 20dBm EDFA i kūkulu ʻia a me ke awa hoʻokahi GPON OLT, e kākoʻo ana i 256 mau mea kākau ma ka radius o 100 mika FTTH uwea. Ke hana nei meGFH1000-KFTTH CATV loaʻa, GRT319 mamao OLT mālama DVB-C STB pāʻoihana wale no nā mea kākau inoa CATV. Ke hana nei meGONU1100WHāʻawi ʻo FTTH ONU, GRT319 Remote OLT i ka 2.5Gbps i lalo o ka punaewele ma waho o CATV RF.
Node ma ka node,GRT319hiki ke kōkua iā CATV MSO i ka hoʻololi ʻana i ka ʻōnaehana HFC CATV i ʻelua ala ʻelua ʻōnaehana FTTH ma ke kumukūʻai kūpono.
