OLT fog ee shabakada HFC ilaa nidaamka FTTH

Juun 28, 2024, Greatway Technology ayaa ku dhawaaqday sii deynta GRT319 Remote OLT. GRT319 Remote OLT waxaa loogu talagalay in lagu beddelo noodhka indhaha ee HFC, iyada oo u beddelaysa 100 mitir ee ugu dambeeya shabakad qaybinta fiilada coaxial ee 100 mitir ee ugu dambeeya shabakadda guriga, iyada oo siinaya labadaba adeegyada DVB-C RF iyo GPON dhammaan macaamiisha CATV. Guryaha Aluminiumka ah ee aan biyaha lahayn, GRT319 waxay leedahay hal deked oo fiber gelin ah halkaas oo xogta 10Gbps iyo 1550nm CATV RF ay si toos ah uga socdaan Headend by WDM, badbaadinta maalgashiga fiber jirridda. GRT319 waxa ay leedahay hal wax soo saar fiber ah oo isku xidha 20dBm EDFA iyo hal deked GPON OLT, taas oo taageerta ilaa 256 macaamiil ah xadhiga 100 mitir ee FTTH. La shaqaynta GFH1000 FTTH CATV aqbalaha, GRT319 Remote OLT waxay u haysaa DVB-C STB kaliya ganacsiga macaamiisha CATV. La shaqaynta GONU1100W FTTH ONU, GRT319 Remote OLT waxay siisaa 2.5Gbps hoos-u-socodka internetka marka laga reebo CATV RF.

Node by node, GRT319 waxay ka caawin kartaa CATV MSO inay u beddesho habka HFC CATV ee hal-jid ah ee nidaamka FTTH laba-geesoodka ah ee miisaaniyada la awoodi karo. 

Waxaa jira malaayiin DVB-C STBs ahKa shaqaynta nidaamka CATV ee hadda jira. Waanu ilaalin doonaa inta aanu soo bandhigayno adeegyo internet oo badan. OLT fog ayaa ka fiican marka HFC ilaa FTTH.

Waxaan ku haynaa shabakada-xiddigaha 1550nm nood kasta oo indhaha ah waxaanan ku soo bandhigaynaa 10Gbps isla fiber-ka noodhka indhaha ee WDM.Noodkii hore ee indhaha waxa lagu badalayaa mid Fog-OLT oo isku meel ah iyo isla sahay koronto.

Qaybiyeyaasha hore ee coaxial iyo fiilooyinka waxaa lagu beddelaa kala qaybiyeyaasha PLC iyo fiilooyinka FTTH si ay u daboosho dhammaan macaamiisha.

  

OLT fog waxay taageertaa gelinta 1 fiber iyo 1 wax soo saarka fiber.

Fiber-ku-soo-saarku wuxuu leeyahay 20dBm 1550nm signal iyo hal GPON OLT ugu badnaan 256 macaamiil ah. 

Aqal kasta oo FTTH ah, waxaa jira TV kaliya oo ah terminal ama TV+Internet-ka ikhtiyaariga ah.

 

Waxay ku taal Shenzhen, Tiknoolajiyada Greatway waa RF ka badan guri naqshadeynta alaabada gudbinta fiber-ka iyo warshad tan iyo 2004, oo bixisa FTTH CATV qaataha, RFoG ONU ee modem fiilada ftth, satellite hal / Twin / Quatro LNB RF oo ka sarreeya GPON, Laba/Afar dayax-gacmeed oo ka sarreeya hal fiber isku xirka, Super Capacitor Battery, GPON iyo GPON+, EoC, 1218MHz CATV gudbiyaha indhaha iyo noodhka indhaha, baahinta heerka AV/ASI/SDI fiber link.
