Product Summary
Kambani yedu ichangoburwa yepamusoro-yekupedzisira mana-yakabuda CATV network optical inogamuchira SR814ST, iyo pre-amplifier inoshandisa yakazara GaAs MMIC, uye iyo post-amplifier inoshandisa maGaAs module. Iine optimized redunhu dhizaini uye 10 makore ehunyanzvi dhizaini ruzivo, chishandiso chakawana zviratidzo zvekushanda zvakanakisa. Uye zvakare, microprocessor control uye dijitari paramende inoratidzira inoita kuti engineering kugadzirisa kuve nyore. Ndiyo midziyo mikuru inodiwa pakuvaka CATV network.
Performance Characteristics
Yedu yepamusoro CATV network optical receiver SR814ST inotora yakakwirira-mhinduro PIN photoelectric conversion chubhu, inogonesa dhizaini dhizaini uye SMT process kugadzirwa, uye inoona yakatsetseka uye inoshanda kutapurirana kwemasaini emagetsi masaini.
Yakatsaurirwa RF attenuation machipi inopa chaiyo mutsara attenuation, nepo yedu GaAs amplifier zvishandiso zvinopa yakakwira kuwana uye yakaderera kukanganisa. Iyo sisitimu inodzorwa ne-single-chip microcomputer (SCM), ine LCD kuratidza paramita, nyore uye intuitive kushanda, uye yakagadzikana kuita.
Iyo AGC sisitimu inova nechokwadi chekuti chikamu chekubuda chinoramba chiripo pamusoro pesimba remaziso re -9 kusvika +2 dBm nekukanganisa kushoma kubva kuCTB neCSO. Iyo sisitimu inosanganisirawo yakachengetwa data yekutaurirana interface, iyo inogona kubatanidzwa kune yemhando II network manejimendi inopindura uye yakabatana kune network manejimendi system.Yese tekinoroji paramita inoyerwa zvinoenderana neGY/T 194-2003, pasi peyakajairwa bvunzo mamiriro.
