Remote OLT kumurongo wa HFC kuri sisitemu ya FTTH

Ku ya 28 Kamena 2024, Ikoranabuhanga rya Greatway ryatangaje gusohora GRT319 ibicuruzwa bya kure bya OLT. GRT319 Remote OLT yagenewe gusimbuza optique ya HFC, ihindura imiyoboro ya metero 100 yanyuma yo gukwirakwiza insinga ya coaxial ya fibre ya metero 100 iheruka kumurongo wurugo, itanga serivise za interineti DVB-C RF na GPON kubakoresha bose ba CATV. Hamwe n'inzu itagira amazi ya Aluminium, GRT319 ifite icyambu kimwe cyinjiza fibre aho amakuru ya 10Gbps na 1550nm CATV RF aturuka muri Headend na WDM, bizigama ishoramari rya fibre. GRT319 ifite fibre imwe isohoka ihuza muri 20dBm EDFA hamwe nicyambu kimwe GPON OLT, ifasha abafatabuguzi bagera kuri 256 mumaradiyo ya metero 100 ya kabili FTTH. Gukorana na GFH1000 FTTH CATV yakira, GRT319 Remote OLT ituma DVB-C STB ubucuruzi gusa kubakoresha CATV. Gukorana na GONU1100W FTTH ONU, GRT319 Remote OLT itanga 2.5Gbps kumurongo wa enterineti usibye CATV RF.

Node by node, GRT319 irashobora gufasha CATV MSO guhindura sisitemu imwe ya HFC CATV muburyo bubiri bwa FTTH kuri bije ihendutse. 

Hano hari amamiriyoni ya DVB-C STBsgukora kuri sisitemu ya CATV. Tuzakomeza kubika mugihe dutangiza serivisi nyinshi za interineti. Remote OLT nibyiza iyo HFC kuri FTTH.

Tugumisha inyenyeri-1550nm kuri buri optique kandi tumenyekanisha 10Gbps kuri fibre imwe kuri optique ya WDM.Ahahoze optique node isimburwa na Remote-OLT imwe ahantu hamwe no gutanga amashanyarazi amwe.

Imiyoboro ya coaxial yahoze hamwe ninsinga byasimbujwe ibice bya PLC hamwe ninsinga za FTTH kugirango bipfundikire abafatabuguzi bose.

Remote OLT ishyigikira fibre 1 yinjiza nibisohoka 1 fibre.

Ibisohoka fibre ifite ibimenyetso 20dBm 1550nm hamwe na GPON OLT imwe kubakoresha 256. 

Kuri buri nzu ya FTTH, hariho TV gusa cyangwa TV ya enterineti.

Iherereye i Shenzhen, Ikoranabuhanga rya Greatway ni RF hejuru yinzu nogukora ibicuruzwa byoherejwe na fibre kuva 2004, itanga imashini ya FTTH CATV, RFoG ONU kuri modem ya kabili modem, icyogajuru kimwe / Twin / Quatro LNB RF hejuru ya GPON, Satelite ebyiri / enye hejuru ya fibre imwe Ihuza, Batteri ya super Capacitor, GPON na GPON +, EoC, 1218MHz CATV itanga imiyoboro ya optique na node ya optique, itumanaho rya AV / ASI / SDI fibre ihuza.
