GFH1000-KP mai karɓar CATV mara ƙarfi don ONU
Bayanin Samfura
GFH1000-KP shine 1550nm mara ƙarfi CATV fiber zuwa mai karɓar gani na gida tare da 1310nm/1490nm WDM madauki daga tashar jiragen ruwa. Bayan yakin zurfin fiber, HFC CATV mai karɓa na gani yana raguwa daga masu biyan kuɗi na 2000, zuwa masu biyan kuɗi 500, masu biyan kuɗi 125, masu biyan kuɗi 50 kuma yanzu masu biyan kuɗi ɗaya lokacin fiber zuwa gida. Tunda ana amfani da amplifier mai ƙarfi mafi girma a cikin tsarin watsa shirye-shiryen CATV na PON, yana yiwuwa a yi amfani da mai karɓa mara ƙarfi wanda ke aiki a -6dBm ~ -1dBm don rage farashin tashar FTTH da amfani da wutar lantarki. A halin yanzu, tun lokacin da aka canza aikin intanet zuwa GPON ko XGPON, GHF1000-KP yana da 45MHz zuwa 1000MHz ko 1218MHz cikakken bandwidth na RF don sabis na watsa shirye-shiryen TV.
GFH1000-KP yana da tashar shigar da kayan gani guda ɗaya, tashar wdm fiber ɗaya da fitarwar RF ɗaya. Kamar na'urorin iyali na ONU, GFH1000-KP yana da gidan filastik mai ɗaukar wuta. Ana shigar da wannan na'urar filogi da wasa cikin sauƙi a aikace-aikacen gida ko SOHO (kananan ofis da ofis ɗin gida). Tare da babban layin photodiode da ingantacciyar madaidaiciyar madaidaiciyar madaidaicin RF, GFH1000-KP har yanzu yana fitar da ingantaccen RF don ko dai TV ɗin analog ko dijital QAM TV don saitin TV ɗaya ko fiye a cikin iyali ɗaya. Ba kamar GFH1000 FTTH CATV mai karɓa tare da ginanniyar GaAs amplifier, GFH1000-KP mara ƙarfi FTTH CATV mai karɓar yana dogara da ƙarfin shigarwar gani don EDFA, ana iya ba da shawarar ƙarfin shigarwar gani na 1550nm ƙasa da -6dBm lokacin da siginar RF shine DVB-C QAM ko -1dBm lokacin da siginar RF ta analog TV ce.
Shigar da 1550nm bandwidth siginar na iya zama 1525nm ~ 1565nm wideband na gani sigina da kunkuntar band 1550nm ~ 1560nm na gani sigina.
WDM na iya tallafawa 1310nm/1490nm GPON na yau da kullun ko 1270nm/1577nm XGPON ko NGPON2. GFH1000-KP yana bawa kowane ɓangare na GPON ONU damar yin aikin RF don watsa tashoshin RF.
Wasu Fasaloli:
• Ƙaƙƙarfan gidaje masu ɗaukar harshen wuta.
• Babban Linearity Photodiode don CATV RF.
• 45 ~ 1000MHz (ƙasa) Fitar RF.
• Babu ikon DC Ƙirar tattalin arziƙin m.
• 1310nm/1490nm Optical Bypass Port zuwa ONU.
• Ana iya haɓaka WDM don haɗawa da tashar tunani na 1270nm/1577nm don XGPON ONU.
