I-OLT ekude yenethiwekhi ye-HFC ukuya kwinkqubo ye-FTTH

NgoJuni 28, 2024, iGreatway Technology yabhengeza ukukhulula imveliso ye-GRT319 Remote OLT. I-GRT319 Ekude i-OLT yenzelwe ukutshintsha indawo ye-HFC ye-optical node, iguqulela i-100 mitha yokugqibela yokuhambisa intambo yentambo ye-coaxial kwi-fiber yokugqibela ye-100 yeemitha kuthungelwano lwasekhaya, inikezela zombini iinkonzo ze-intanethi ze-DVB-C RF kunye ne-GPON kubo bonke ababhalisi beCATV. Ngezindlu ze-Aluminium zokungena kwamanzi, i-GRT319 ine-fiber input port enye apho idatha ye-10Gbps kunye ne-1550nm CATV RF zisuka ngqo kwi-Headend yi-WDM, igcina i-trunk fiber investment. I-GRT319 inemveliso yefiber enye edibanisa i-20dBm EDFA eyakhelwe-ngaphakathi kunye ne-port eyodwa ye-GPON OLT, exhasa ukuya kubabhalisi be-256 kwi-radius ye-100 yemitha yentambo ye-FTTH. Ukusebenza kunye ne-GFH1000 FTTH CATV receiver, i-GRT319 Remote OLT igcina i-DVB-C STB kuphela ishishini lababhalisi beCATV. Ukusebenza neGONU1100W FTTH ONU, GRT319 Remote OLT ibonelela nge-2.5Gbps phantsi kwe-intanethi yokusakaza ngaphandle kwe-CATV RF.

I-Node nge-node, i-GRT319 inokuncedisa i-CATV MSO ukuguqula indlela enye ye-HFC CATV inkqubo ibe yinkqubo ye-FTTH yeendlela ezimbini kuhlahlo lwabiwo-mali olufikelelekayo. 

Kukho izigidi DVB-C STBsukusebenza kwinkqubo yangoku yeCATV. Siza kuzigcina ngelixa sazisa iinkonzo ezininzi ze-intanethi. I-OLT ekude ingcono xa i-HFC isiya kwi-FTTH.

Sigcina i-1550nm star-network kwi-node nganye ye-optical kwaye sazise i-10Gbps kwi-fiber efanayo kwi-node ye-optical nge-WDM.Indawo yangaphambili ye-optical node ithathelwa indawo yi-Remote-OLT enye kwindawo enye kunye nonikezelo lwamandla olufanayo.

Izahlulo zangaphambili ze-coaxial kunye neentambo zitshintshwa ziqhekeza ze-PLC kunye neentambo ze-FTTH ukugubungela bonke ababhalisi.

I-OLT ekude ixhasa i-fiber input ye-1 kunye ne-1 ye-fiber output.

Ifiber ephumayo inesiginali ye-20dBm 1550nm kunye ne-GPON OLT enye yababhalisi abangama-256. 

Kwindlu nganye ye-FTTH, kukho i-terminal ye-TV kuphela okanye iTV+ iinketho ze-Intanethi.

Ifumaneka e-Shenzhen, i-Greatway Technology yi-RF phezu kwe-fiber yokuhanjiswa kwemveliso yoyilo lwendlu kunye nomzi-mveliso ukususela ngo-2004, inikezela nge-FTTH CATV receiver, RFoG ONU ye-ftth cable modem, i-satellite single / Twin / Quatro LNB RF phezu kwe-GPON, iisathelayithi ezimbini / ezine phezu kwefayibha enye. ikhonkco, iBattery ye-Super Capacitor, i-GPON kunye ne-GPON +, i-EoC, i-1218MHz i-CATV i-optical transmitter kunye ne-node optical, iklasi yokusasaza i-AV / ASI / SDI i-fiber link.
