PRODUCT DETAIL

Mafotokozedwe Akatundu

GFH1000-K ndi 1550nm CATV CHIKWANGWANI kupita kunyumba kuwala wolandila ndi 1310nm/1490nm WDM loop kunja doko. Pambuyo pa kampeni yozama ya fiber, HFC CATV optical receiver service imachepa kuchokera kwa olembetsa a 2000, mpaka olembetsa 500, olembetsa 125, olembetsa 50 ndipo tsopano olembetsa m'modzi akakhala ndi fiber kunyumba. Popeza ntchito ya intaneti imasamutsidwa ku GPON kapena XGPON, GHF1000-K ili ndi 45MHz mpaka 1000MHz kapena 1218MHz full RF bandwidth pa ntchito yowulutsa pa TV.

GFH1000-K ili ndi doko limodzi lolowera, doko limodzi la fiber wdm, 12V DC mphamvu yamagetsi ndi kutulutsa kwa RF kumodzi. Monga zida za banja la ONU, GFH1000-K ili ndi nyumba zapulasitiki zotsekereza moto zokhala ndi zitsulo zamkati kuti zitsimikizire kudzipatula kwa RF ndikugwira ntchito.

Ndi mapangidwe omangidwira a AGC, GFH1000-K ndi pulagi ndi chida chosewera chomwe chimayikidwa mosavuta kunyumba kapena pulogalamu ya SOHO. Ili ndi mzere wapamwamba wa photodiode komanso phokoso lotsika la GaAs amplifier, imatulutsa RF yapamwamba kwambiri ya analogi TV kapena digito ya QAM TV pa TV imodzi kapena zingapo m'banja limodzi. Mphamvu yolowera ya 1550nm imatha kukhala yotsika ngati -15dBm pomwe chizindikiro cha RF ndi DVB-C QAM kapena -8dBm pomwe chizindikiro cha RF ndi TV ya analogi. Doko la RF lili ndi chitetezo chowonjezera ndipo mulingo wa RF ukhoza kusinthidwa ngati njira ya MGC yatsegulidwa.

The athandizira 1550nm siginecha bandiwifi akhoza kukhala 1525nm ~ 1565nm wideband kuwala siginecha ndi yopapatiza gulu 1550nm ~ 1560nm kuwala chizindikiro. WDM imatha kuthandizira 1310nm/1490nm GPON kapena 1270nm/1577nm XGPON kapena NGPON2. GFH1000-K imatha kuloleza Greatway ONU kapena gulu lililonse lachitatu la ONU yokhala ndi ntchito ya RF yowulutsira ma mayendedwe a RF.
