I-GRT319 Ekude ye-OLT ye-HFC ukuya ku-FTTH
I-GRT319 I-OLT Ekude iklanyelwe ukuvala indawo ye-HFC optical node, iguqule inethiwekhi yokugcina ye-coaxial cable yamamitha ayi-100 ibe yifayibha yokugcina engamamitha ayi-100 kunethiwekhi yasekhaya, inikezela ngezinsizakalo ze-inthanethi ze-DVB-C RF kanye ne-GPON kubo bonke ababhalisile be-CATV. Ngezindlu ze-Aluminium ezivikela amanzi, i-GRT319 inembobo yokufaka eyodwa yefayibha lapho idatha engu-10Gbps kanye ne-1550nm CATV RF ivela ngokuqondile ku-Headend nge-WDM, konga ukutshalwa kwe-trunk fiber. I-GRT319 inokukhishwa kwefayibha eyodwa ehlanganisa eyakhelwe ngaphakathi engu-20dBm EDFA kanye nembobo eyodwa ye-GPON OLT, esekela ababhalisile abangafika kwabangu-256 kububanzi bentambo ye-FTTH engamamitha ayi-100. Isebenza ne-GFH1000 FTTH CATV receiver, i-GRT319 Remote OLT igcina i-DVB-C STB kuphela ibhizinisi lababhalisile be-CATV. Isebenza ne-GONU1100W FTTH ONU, i-GRT319 Remote OLT inikeza i-inthanethi engu-2.5Gbps ngaphandle kwe-CATV RF.
I-Node by node, i-GRT319 ingasiza i-CATV MSO ukuguqula indlela eyodwa ye-HFC CATV uhlelo lube lwezindlela ezimbili ze-FTTH uhlelo ngesinyathelo ngesabelomali esithengekayo.
Kunezigidi zama-DVB-C STB asebenza ohlelweni lwamanje lwe-CATV. Sizowagcina ngenkathi sethula amasevisi e-inthanethi engeziwe. Isilawuli kude se-OLT singcono uma i-HFC iya ku-FTTH.
Sigcina inethiwekhi yenkanyezi engu-1550nm endaweni ngayinye yokubona futhi sethula i-10Gbps ku-fibre efanayo endaweni ye-optical node nge-WDM.
Indawo yangaphambili yokubona ithathelwa indawo yi-Remote-OLT eyodwa endaweni efanayo kanye nokunikezwa kwamandla okufanayo.
Izihlukanisi zangaphambili ze-coaxial nezintambo zithathelwa indawo yizihlukanisi ze-PLC nezintambo ze-FTTH ukuze zimboze bonke ababhalisile.
I-OLT yesilawuli kude isekela okokufaka kwefayibha engu-1 kanye nokukhishwa kwefayibha engu-1.
I-fiber ephumayo inesignali engu-20dBm 1550nm kanye ne-GPON OLT eyodwa yababhalisile abangu-256.
Efulethini ngalinye le-FTTH, kunetheminali ye-TV kuphela noma izinketho zetheminali ye-TV+I-inthanethi.
