GFH1000-KP alailagbara CATV olugba fun ONU
ọja Apejuwe
GFH1000-KP jẹ okun CATV ti ko ni agbara 1550nm si olugba opiti ile pẹlu 1310nm / 1490nm WDM lupu jade ni 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 bi o ti jẹ pe ampilifaya opiti agbara ti o ga julọ ni lilo pupọ ni eto PON igbohunsafefe CATV, o ṣee ṣe lati lo olugba opitika ti ko ni agbara ṣiṣẹ ni -6dBm ~ -1dBm lati dinku idiyele ebute FTTH ati agbara agbara.Nibayi, niwọn igba ti a ti gbe iṣẹ intanẹẹti lọ si GPON tabi XGPON, GHF1000-KP ni 45MHz si1000MHz tabi 1218MHz ni kikun bandiwidi RF fun iṣẹ igbohunsafefe TV.
GFH1000-KP ni ibudo igbewọle opiti kan, ibudo wdm fiber kan ati abajade RF kan.Gẹgẹbi awọn ẹrọ ẹbi ONU, GFH1000-KP ni ile idaduro ina.Pulọọgi ati ẹrọ ere yii ni irọrun fi sori ẹrọ ni ile tabi ohun elo SOHO (ọfiisi kekere ati ọfiisi ile).Pẹlu photodiode linearity giga ati ni titunse palolo RF ibaamu Circuit daradara, GFH1000-KP tun ṣe agbejade RF didara itẹwọgba fun boya TV afọwọṣe tabi QAM TV oni-nọmba fun awọn eto TV kan tabi diẹ sii ninu idile kan.Ko dabi olugba GFH1000 FTTH CATV pẹlu ampilifaya GaAs ti a ṣe sinu, GFH1000-KP alailagbara FTTH CATV olugba gbarale agbara titẹ opiti fun EDFA, agbara igbewọle opiti 1550nm le ṣe iṣeduro bi kekere bi -6dBm nigbati ifihan RF jẹ DVB-C QAM tabi -1dBm nigbati ifihan RF jẹ TV afọwọṣe.
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-KP ngbanilaaye eyikeyi GPON ONU ẹnikẹta pẹlu iṣẹ RF fun igbohunsafefe awọn ikanni RF.
