Fiber Optic Node CATV

Ntsiab lus

SR1004 sab nraum zoov qhov muag hluav taws xob yog ob txoj kev kho qhov muag rau cov cuab yeej sib koom ua ke tau ua raws ntau xyoo kev tshawb fawb txog CATV HFC fiber xa cov khoom siv, tsim tshwj xeeb rau HFC tus qauv ob txoj kev loj hauv cheeb tsam broadband. ThisFiber Optic Node CATV yog qhov kev xaiv zoo rau kev tsim kho kom muaj txiaj ntsig zoo tsim kev kub hnyiab HFC cov chaw ua haujlwm hauv cheeb tsam broadband.

Cov yam ntxwv

1.Full CPU tswj lub tshuab ua haujlwm, LCD qhia cov tsis xws luag, xws li cov qauv tso tawm / theem. Kev tswj cov cuab yeej muaj cuab kav ua tau yooj yim thiab xav tau, thiab kev ua tau zoo yog ruaj khov.Reduced ntau ntawm cov khoom siv xaiv tau.

2.This Fiber Optic Node CATVSR1004adopts siab kho qhov muag AGC thev naus laus zis, kho qhov muag AGC tswj: :2dBm ～ -9 / -8 / -7dBm kho tau.

3.Two-channel kho qhov muag teeb liab txais txhua cov thaub qab, tuaj yeem tsim lub tshuab hloov pauv tsis siv neeg, kev tuaj yeem hloov mus rau phau ntawv hloov.

4.Optimizing Circuit Court tsim, SMT cov txheej txheem ntau lawm, ua kom zoo tag nrho cov teeb liab txoj kab, ua rau cov teeb liab teeb hluav taws xob xa hluav taws xob ntau dua, RF linear Performance index siab dua.

5. kev tshaj lij hluav taws xob RF hluav taws xob kho kom haum rau nti, RF hluav taws xob kho qhov hluav taws xob sib luag, cov kab hluav taws xob zoo, siab qhov tseeb.

6.GaAs amplifier ntaus ntawv, fais fab tso zis ntau lawm, qhov siab nce siab thiab distortion qis.

7.Cov kev rov qab adopts kev RF hluav taws xob adjustable attenuation nti hloov chaw ua peb-xeev hloov.
