GRT319 OLT mamao no HFC a FTTH

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 nei me GONU1100W FTTH ONU, hāʻawi ʻo GRT319 Remote OLT i 2.5Gbps pūnaewele 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 ʻaoʻao i kēlā me kēia pae ma ka waihona kālā kūpono.

Aia nā miliona o nā DVB-C STB e hana nei 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.
