Tsananguro yechigadzirwa
Kupfupika muchidimbu
SR812ST (R) ndiyo yedu yazvino-giredhi-giredhi maviri-kubuda Catv Network Optical Receiver. Iyo pre-amplifier inogamuchira yakazara-gaas mic, post-amplifier inotora iyo gaas module. Optimised Dunhu Dunhu rakabatanidzwa nemakore edu gumi ehunyanzvi hwekugadzira ruzivo, ita kuti zvishandiso zviite zvakanaka mashandiro ezviitiko. Microprocessor Kudzora, kuratidzwa kwedhijitari kweiyo parameter, iyo yeinjiniya yekubvumirana inonyanya nyore. Iyo ndiyo midziyo mikuru yekuvaka iyo Catv network.
Maitiro ekuita
- Yakakwira Mhinduro PINсEElectric kutendeuka tube.
- Optimised Dunhu Radhi, Smt Production Production, uye Yakagadziriswa Signal Nzira inoita kuti mapikicha asainiridze kuendesa zvakanyanya.
- Nhangwe RF Attenuation Chip, neakanaka rf gentenuation uye kuenzana mutsara, yakakwirira chokwadi.
- Gaas amplifier mudziyo, simba rakabudiswa pachena, nekuwana kwakanyanya uye kukanganisa kwakaderera.
- Single chip microcomputer (scm) kudzora michina inoshanda, LCD inoratidza paramita, nyore uye intuitive inoshanda, uye kuita kwakagadzikana.
- Yakanakisa Agc performance, apo iyo yekuisa Optic simba renji iri -9 ~ 2dbm, iyo inobuda inochengetedza isina kuchinjika, uye ctb uye cso zvechokwadi isina kuchinjika.
- Yakachengetedzwa data yekutaurirana interface, inogona kubatana nekirasi
- Dzorera kubviswa kunogona kusarudza burst mode kupinza kuderedza ruzha ruzha uye kuderedza iyo forepart kugamuchira nhamba.
Batanidza Kuedzwa Kwemamiriro
Iyo technical parameter yeiyi bhuku zvichienderana nenzira yekuyera yeGy / T 194-2003
1. Tumira Ompical gamuchira chikamu: ine 10km standard Optical fiber, passive Optical Atteniator, uye Standard Optical Transmitter yakanyora iyo yekuyedza link. Set 59 Pal-D Analog TV Channel Signel Signel chiratidzo che45 / 87mhz ~ 550mhz pasi peiyo yakatarwa yekubatanidza. Tumira Dhijitari modulation chiratidzo che550mhz ~ 862 / 1003mhz, iyo dijitital modulation sign (mu 8 MHZ Bandwidth) ndeye 10DB bandwidth Kana iyo yekuisa Spurity Simba reOptical Receiver iri -2Dbm, iyo RF inobuda mu 108dbμv, ine 9DB inobuda, kuyera iyo C / CTB, CST, CSE, uye C / N.
2..
Ongorora: Kana iyo yakavezwa yekubuda kwehurongwa hwehurongwa hwehurongwa hwehurongwa hwekugadzirisa Kana iyo system yekugadzirisa kugadziridza (ndiko kuti, chaiyo yekufambisa nzira dzinodzora), iyo yakaiswa mwero wemidziyo ichawedzerwa.
Chivimbo chehushamwari: Kufunga kuti iwe unoisa iyo RF chiratidzo kusvika 6 ~
