Ho na le limilione tsa li-STB tsa DVB-C tse sebetsang ho sistimi ea hajoale ea CATV HFC. Ho nkela li-STB tsena kaofela tsa DVB-C ho bitsa chelete e ngata 'me ha ho sebetse ho basebelisi ba bangata ba CATV. Ho sa le joalo, ho bitsa chelete e ngata ho sebelisa modem ea cable ho fana ka litšebeletso tsa inthanete holim'a sistimi ea HFC. 1550nm overlay FTTH sistimi ke khetho e theko e tlase bakeng sa DVB-C RF le Marang-rang.Sebopeho se tloaelehileng sa marang-rang sa HFC se ipapisitse le marang-rang a linaleli. Lithapo tsa li-trunk fiber li hokahantsoe ka kotloloho ho li-node tse ngata tsa optical (mohlalaGWR1200) ho tlohaGWT35001550nm transmitter e hloohong, 'me node e' ngoe le e 'ngoe ea mahlo e sebeletsa makholo a ba ngolisitseng CATV holim'a cable ea coaxial.
Greatway Technology e fana ka maikutlo a ho kenyaGRT319OLT e hole sebakeng sa optical node ea sistimi ea HFC ho boloka matsete a trunk fiber cable le ho boloka lits'ebeletso tsohle tsa DVB-C RF. Re boloka marang-rang a linaleli tsa 1550nm ho node e 'ngoe le e' ngoe ea optical mme re kenyelletsa 2.5Gbps kapa 10Gbps ka fiber e tšoanang ho fiber optical node ka WDM.
Node ea pele ea optical e nkeloa sebaka ke e le 'ngoeGRT319Remote-OLT sebakeng se le seng le phepelo ea motlakase e tšoanang. Li-splitter tsa khale tsa coaxial le likhoele li nkeloa sebaka ke li-splitter tsa PLC le likhoele tsa FTTH ho koahela ba ngolisitseng bohle.
GRT319Remote OLT e etselitsoe ho nkela sebaka sa HFC optical node, ho fetola marang-rang a ho qetela a 100 meter coaxial cable ho ba fiber ea ho qetela ea 100 meter ho marang-rang a lapeng, e fanang ka litšebeletso tsa inthanete tsa DVB-C RF le GPON ho bohle ba ngolisitseng CATV. E na le matlo a Aluminium a sa keneleng metsi,GRT319e na le kou e le 'ngoe ea ho kenya fiber moo data ea 10Gbps le 1550nm CATV RF e tsoang ka kotloloho ho tsoa ho Headend ke WDM, ho boloka matsete a trunk fiber. GRT319 e na le phallo e le 'ngoe ea fiber e kopanyang 20dBm EDFA e hahiloeng ka har'a 20dBm EDFA le boema-kepe bo le bong GPON OLT, e ts'ehetsang ba ngolisitseng ba ka bang 256 sebakeng sa thapo ea 100 metres FTTH. Ho sebetsa leGFH1000-KMoamoheli oa FTTH CATV, GRT319 Remote OLT e boloka DVB-C STB e le khoebo feela bakeng sa ba ngolisitseng CATV. Ho sebetsa leGONU1100WFTTH ONU, GRT319 Remote OLT e fana ka 2.5Gbps ho theosa le inthanete ntle le CATV RF.
Node ka node,GRT319e ka thusa CATV MSO ho fetolela sistimi ea HFC CATV ea tsela e le 'ngoe hore e be sistimi ea FTTH ea litsela tse peli ka tekanyetso e fumanehang.
