Pfupiso Pfupi
SR812ST(R) ndiyo itsva CATV network optical receiver yedu ine magirazi maviri epamusoro. Pre-amplifier inoshandisa full-GaAs MMIC, post-amplifier inoshandisa GaAs module. Dhizaini yedunhu yakagadziriswa pamwe chete nemakore edu gumi eruzivo rwekugadzira, zvinoita kuti michina iwane ma indexes akanaka ekushanda. Kudzora microprocessor, kuratidzwa kwedhijitari kwema parameter, uye kugadzirisa matambudziko einjiniya zviri nyore. Ndiyo michina mikuru yekuvaka network yeCATV.
Hunhu hweKushanda
- Chubhu yekushandura PIN ine mhinduro yepamusoro.
- Dhizaini yedunhu yakagadziriswa, kugadzirwa kwemaitiro eSMT, uye nzira yechiratidzo yakagadziriswa inoita kuti kutumira kwechiratidzo chemagetsi kuve nyore.
- Chip yekuderedza RF yakagadzirwa nehunyanzvi, ine RF attenuation yakanaka uye linear yakaenzana, yakanyatsojeka.
- Mudziyo we amplifier weGaAs, simba rinobuda kaviri, rine gain yakawanda uye kukanganiswa kwakaderera.
- Midziyo yekudzora yeSingle Chip Microcomputer (SCM) iri kushanda, LCD inoratidza maparameter, zviri nyore kushandisa uye mashandiro ari nyore kushandisa, uye mashandiro akagadzikana.
- Kushanda zvakanaka kweAGC, kana simba rekupinda re optical riri －9～＋2dBm, huwandu hwekubuda hunoramba husina kuchinja, uye CTB neCSO hazvichinji zvachose.
- Nzvimbo yekutaurirana data yakachengetwa, inogona kubatana nekirasi Ⅱ network management responder, uye mukana wekushandisa network management system.
- Kudzosa emission kunogona kusarudza burst mode kuderedza zvakanyanya kuungana kweruzha uye kuderedza nhamba yemugamuchiri wepamberi.
Mamiriro Ekuyedza Chinongedzo
Magadzirirwo ehunyanzvi ebhuku rino zvichienderana nenzira yekuyera yeGY/T 194-2003
1. Chikamu chekugamuchira ma "forward optical": chine fiber ye "standard optical fiber" ye10km, passive optical attenuator, uye "standard optical transmitter" zvakagadzira "testing link". Isa 59 PAL-D analog TV channel signal pa 45/87MHz～550MHz pasi pe "link loss" yakatarwa. Tumira "digital modulation signal" pa 550MHz～862/1003MHz, "digital modulation signal level" (mu 8 MHz bandwidth) yakaderera ne10dB pane "analog signal carrier level". Kana simba re "input optical" re "optical receiver" riri -2dBm, "RF output level" iri 108dBμV, ne "9dB output tilt", yera C/CTB, C/CSO, uye C/N.
2. Chikamu chekutumira ma "backward optical transmit": Link flatness uye NPR dynamic range ndiwo ma "link indexes" anoumbwa ne "backward optical transmitter" uye "backward optical receiver".
Cherechedza: Kana chiyero chekubuda chakayerwa chiri chimiro chakazara chesisitimu uye simba remagetsi rinogashira riri -2dBm, mudziyo unosangana nechikamu chepamusoro chekubuda cheindekisi yekubatanidza. Kana chimiro chesisitimu chikadzikira (ndiko kuti, nzira dzekutumira dzinodzikira), chiyero chekubuda chemuchina chichawedzerwa.
Ziviso Yeushamwari: Ipa zano rekuti uise chiratidzo cheRF ku6~9dB tilt output mu practical engineering application kuti uvandudze nonlinear index (pasi pe node) ye cable system.
