Catv 4 Chaw nres nkoj sab nraum zoov kho qhov muag khoom txais
catv 4 chaw nres nkoj sab nrauv kho qhov muag txais khoom
Saib ib muag khoom
SR812B(CATV 4 Chaw nres nkoj sab nraud txais khoom)yog qhov tawm ntawm sab nraud kho qhov muag nrog cov lus teb siab siab PIN photoelectric hloov lub raj, tuaj yeem txuas nrog kev tswj hwm hauv chaw taws teeb, nkag tau yooj yim rau kev tswj hwm lub network.
Lub pre-amp ntawmcatv 4 chaw nres nkoj putdoor kho qhov muag txaistxais yuavtxhua-GaAs MMIC ua kom nrov dua thiab cov tom qab-amp adopts GaAs zog coj ob lub zog ntxiv (cov qauv no muaj ob tus qauv, M qauv RF attenuation thiab kev sib luag los txais kev tsim kho tsis tu ncua, MF qauv nrog sib txawv tsis sib thooj thiab sib npaug sib xyaw rau cov neeg siv kev xaiv. tseem xaiv ntau ntxiv rau qhov ua tau zoo tshaj qhov ua tau raws li qhov xav tau tiag tiag).
Nthuav dav Duab
Cov Nta Tseem Ceeb
1.High teb PIN photoelectric hloov lub raj.
2. 1G bandwidth tsim.
3.Txiav bar LED lub zog ntsuas qhov ntsuas, qhia qhov tseeb ntxiv rau lub zog kho qhov muag.
4.Optimized Circuit Court tsim, qib uantej adopts SMT ua, thaum tom qab theem theem adopts module ua kom nrov Circuit Court ua rau ua rau photoelectric teeb liab kis tau zoo dua.
5. Lub zog ua haujlwm ob npaug, cov txiaj ntsig siab thiab distortion qis.
6. Optical AGC tswj, thaum lub tswv yim nkag mus rau lub zog hluav taws xob yog -7 ~ +2dBm, qib tsim tawm, CTB thiab CSO tsis hloov pauv.
