GFH1000-K jẹ 1550nm CATV okun si olugba opiti ile pẹlu 1310nm / 1490nm WDM lupu jade ibudo.Lẹhin ipolongo jinlẹ fiber, agbegbe iṣẹ olugba opitika HFC CATV dinku lati awọn alabapin 2000, si awọn alabapin 500, awọn alabapin 125, awọn alabapin 50 ati bayi awọn alabapin kan nigbati okun si ile.Niwọn igba ti a ti gbe iṣẹ intanẹẹti lọ si GPON tabi XGPON, GHF1000-K ni 45MHz si1000MHz tabi 1218MHz ni kikun bandiwidi RF fun iṣẹ igbohunsafefe TV.
GFH1000-K ni ibudo igbewọle opiti kan, ibudo wdm fiber kan, igbewọle agbara 12V DC ati abajade RF kan.Bii awọn ẹrọ ẹbi ONU, GFH1000-K ni ile idaduro ina pẹlu ile irin ti inu lati rii daju ipinya RF ati iṣẹ.
Pẹlu apẹrẹ AGC ti a ṣe sinu, GFH1000-K jẹ pulọọgi ati ẹrọ ere ni irọrun fi sori ẹrọ ni ile tabi ohun elo SOHO.O ni photodiode linearity giga ati ariwo kekere GaAs ampilifaya, awọn abajade RF ti o ga julọ fun boya TV afọwọṣe tabi oni-nọmba QAM TV fun awọn eto TV kan tabi diẹ sii ninu idile kan.Agbara igbewọle opiti 1550nm le jẹ kekere bi -15dBm nigbati ifihan RF jẹ DVB-C QAM tabi -8dBm nigbati ifihan RF jẹ TV afọwọṣe.Ibudo RF ni aabo gbaradi ati ipele iṣelọpọ RF le jẹ adijositabulu ti aṣayan MGC ba ti muu ṣiṣẹ.
Iwọn bandiwidi ifihan agbara 1550nm le jẹ 1525nm ~ 1565nm wideband opitika ifihan agbara ati okun dín 1550nm ~ 1560nm ifihan agbara opitika.WDM le ṣe atilẹyin deede 1310nm/1490nm GPON tabi 1270nm/1577nm XGPON tabi NGPON2.GFH1000-K le mu Greatway ONU ṣiṣẹ tabi ONU ẹnikẹta eyikeyi pẹlu iṣẹ RF fun igbohunsafefe awọn ikanni RF.
Awọn ẹya miiran:
• Iwapọ ṣiṣu ina retarding ile.
• Photodiode Linearity giga fun CATV RF.
• 45 ~ 1000MHz (isalẹ) RF Ijade (45 ~ 1218MHz iyan).
• Opitika AGC ibiti: -10dBm ~ 0dBm.
• Iyan MGC ibiti: 0 ~ 15dB.
• 1310nm/1490nm Optical Fori Port to ONU.
• WDM le ṣe igbegasoke si pẹlu 1270nm/1577nm ibudo afihan fun XGPON ONU.
• Agbara DC ati itọka LED titẹ opitika.
• 12V DC ohun ti nmu badọgba agbara.
