GRT319 Remote OLT bakeng sa HFC ho ea FTTH

GRT319 Remote OLT e etselitsoe ho nka 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. Ka matlo a Aluminium a sa keneleng metsi, GRT319 e na le koung e le 'ngoe ea ho kenya fiber moo data ea 10Gbps le 1550nm CATV RF e tsoang ka kotloloho ho Headend ke WDM, e bolokang 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 le GFH1000 FTTH CATV receiver, GRT319 Remote OLT e boloka DVB-C STB e le khoebo feela bakeng sa ba ngolisitseng CATV. Ho sebetsa le GONU1100W FTTH ONU, GRT319 Remote OLT e fana ka marang-rang a 2.5Gbps ntle le CATV RF.

Node ka node, GRT319 e ka thusa CATV MSO ho fetolela sistimi ea HFC CATV ea tsela e le 'ngoe hore e be sistimi ea FTTH ea mekhoa e 'meli mohato ka mohato ho tekanyetso e fumanehang.

Ho na le limilione tsa DVB-C STBs tse sebetsang tsamaisong ea hajoale ea CATV. Re tla li boloka ha re ntse re hlahisa litšebeletso tse ling tsa inthanete. Remote OLT e betere ha HFC ho leba FTTH. 

Re boloka marang-rang a linaleli tsa 1550nm ho node e 'ngoe le e' ngoe ea optical mme re kenyelletsa 10Gbps ka fiber e tšoanang ho node ea optical ka WDM.

Node ea khale ea optical e nkeloa sebaka ke Remote-OLT e le 'ngoe sebakeng se le seng le matla a 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.

Remote OLT e ts'ehetsa tlhahiso ea fiber e le 1 le tlhahiso e le 'ngoe ea fiber.

Fiber e hlahisoang e na le letšoao la 20dBm 1550nm le GPON OLT e le 'ngoe bakeng sa ba ngolisitseng ba 256. 

Ka foleteng e 'ngoe le e 'ngoe ea FTTH, ho na le likhetho tsa TV feela kapa TV+ Internet.
