OLT mamao no ka pūnaewele HFC i ka ʻōnaehana FTTH

Iune 28, 2024, hoʻolaha ʻo Greatway Technology i ka hoʻokuʻu ʻana i ka huahana GRT319 Remote OLT. Hoʻolālā ʻia ʻo GRT319 Remote OLT e pani i ka node optical HFC, e hoʻohuli ana i ka 100 mika coaxial cable distribution network hope loa i ka fiber 100 mika hope loa i ka pūnaewele home, e hāʻawi ana i nā lawelawe pūnaewele DVB-C RF a me GPON i nā mea kākau inoa CATV a pau. Me ka Aluminum wai-hōʻoia hale, GRT319 i hoʻokahi fiber komo awa kahi 10Gbps data a me 1550nm CATV RF pololei mai Headend e WDM, e mālama ana i ke kumu kūʻai pulupulu. Loaʻa iā GRT319 hoʻokahi fiber output e hoʻohui ana i ka 20dBm EDFA i kūkulu ʻia a me ke awa hoʻokahi GPON OLT, e kākoʻo ana i 256 mau mea kākau ma ka radius o 100 mika FTTH uwea. Ke hana nei me GFH1000 FTTH CATV mea hoʻokipa, mālama ʻo GRT319 Remote OLT i ka ʻoihana DVB-C STB wale nō no nā mea kākau inoa CATV. Ke hana pū nei me GONU1100W FTTH ONU, hāʻawi ʻo GRT319 Remote OLT i ka 2.5Gbps ma lalo o ka punaewele ma waho o CATV RF.

Node ma ka node, hiki iā GRT319 ke kōkua iā CATV MSO i ka hoʻololi ʻana i ka ʻōnaehana HFC CATV ʻaoʻao hoʻokahi i ʻōnaehana FTTH ʻelua ala ma ke kumukūʻai kūpono. 

Aia nā miliona o nā DVB-C STBe hana ana ma ka ʻōnaehana CATV o kēia manawa. E mālama mākou iā lākou i ka wā e hoʻolauna ana i nā lawelawe pūnaewele hou aʻe. ʻOi aku ka maikaʻi o ka OLT mamao ke HFC a FTTH.

Mālama mākou i ka 1550nm star-network i kēlā me kēia node optical a hoʻokomo i ka 10Gbps ma ka fiber like i ka node optical e WDM.Hoʻololi ʻia ka node optical mua e kahi Remote-OLT ma kahi like a me ka lako mana like.

Hoʻololi ʻia nā mea hoʻokaʻawale coaxial mua a me nā kaula e nā PLC splitters a me nā kaula FTTH e uhi i nā mea kākau inoa āpau.

Kākoʻo ʻo OLT mamao i ka hoʻokomo fiber 1 a me ka hoʻopuka fiber 1.

ʻO ka fiber output he 20dBm 1550nm hōʻailona a hoʻokahi GPON OLT no ka nui o nā mea kākau inoa 256. 

Ma kēlā me kēia keʻena FTTH, aia nā pahu TV a i ʻole TV+Internet mau koho.

Aia ma Shenzhen, Greatway Technology he RF ma luna o ka fiber transmission huahana hoʻolālā hale a me ka hale hana mai 2004, e hāʻawi ana i ka mea hoʻokipa FTTH CATV, RFoG ONU no ka ftth cable modem, satellite single / Twin / Quatro LNB RF ma luna o GPON, ʻElua / ʻEhā mau satellite ma luna o hoʻokahi fiber. loulou, Super Capacitor Battery, GPON a me GPON +, EoC, 1218MHz CATV optical transmitter a me ka node optical, hoʻolaha papa AV / ASI / SDI fiber link.
