Product Description
Muchidimbu Muchidimbu
SR812ST(R) ndiyo yedu yazvino-yepamusoro-giredhi-mbiri-yakabuda CATV network yekuona inogamuchira. Iyo pre-amplifier inotora yakazara-GaAs MMIC, post-amplifier inotora iyo GaAs module. Yakakwenenzverwa yedunhu dhizaini yakasanganiswa nemakore edu gumi ehunyanzvi dhizaini ruzivo, ita kuti michina iwane yakanaka performance indexes. Microprocessor kutonga, kuratidzwa kwedhijitari kwemaparamita, iyo engineering debugging yakanyanya nyore. Ndiyo midziyo mikuru yekuvaka iyo CATV network.
Performance Characteristics
-Yakakwira mhinduro PIN photoelectric shanduko chubhu.
- Yakagadziridzwa dhizaini dhizaini, SMT dhizaini kugadzirwa, uye yakagadziridzwa chiratidzo nzira inoita kuti iyo photoelectric chiratidzo chekufambisa chiwedzere kutsetseka.
- Specialized RF attenuation chip, ine yakanaka RF attenuation uye yakaenzana mutsara, yakakwirira kunyatso.
-GaAs amplifier mudziyo, simba rakapetwa kaviri kuburitsa, nekuwana yakakwira uye yakaderera kukanganisa.
-Single Chip Microcomputer (SCM) inodzora midziyo inoshanda, LCD inoratidza ma paramita, nyore uye intuitive mashandiro, uye yakagadzikana kuita.
-Kuita kwakanakisa kweAGC, kana iyo yekuisa yemagetsi simba renji iri －9～＋2dBm, iyo yekubuda level inoramba isina kuchinjika, uye CTB neCSO hazvina kushanduka.
- Yakachengetedzwa data yekutaurirana interface, inogona kubatana nekirasi Ⅱ network manejimendi inopindura, uye kuwana kune network manejimendi system.
-Kudzosera emission kunogona kusarudza burst modhi yekudzikisa zvakanyanya kutenderera kweruzha uye kuderedza nhamba yekumberi inogamuchira.
Link Testing Conditions
Iyo tekinoroji paramita yebhuku rino zvinoenderana nenzira yekuyera yeGY/T 194-2003.
1. Forward optical receive part: ine 10km yakajairika optical fiber, passive optical attenuator, uye standard optical transmitter yakagadzira chinongedzo chekuyedza. Seta 59 PAL-D analog TV chiteshi chiratidzo pahupamhi hwe45/87MHz ~ 550MHz pasi peyakatsanangurwa yekubatanidza kurasikirwa. Tumira dhijitari modulation siginecha pahupamhi hwe550MHz ~862/1003MHz, iyo dhijitari modulation siginecha nhanho (mu8 MHz bandwidth) iri 10dB yakaderera pane yeanalogi chiratidzo chekutakura. Kana iyo yekupinza yemagetsi yemagetsi inogamuchira iri -2dBm, iyo RF yekubuda mwero i108dBμV, ine 9dB inobuda yakarereka, kuyera C/CTB, C/CSO, uye C/N.
2. Backward Optical transmit part: Link flatness uye NPR dynamic range ndiwo ma link indexes anoumbwa ne backward optical transmitter uye backward optical receiver.
Ongorora: Kana iyo yakatemerwa yekubuda nhanho ndiyo yakazara sisitimu yekumisikidzwa uye iyo yekugamuchira yekuona simba iri -2dBm, iyo midziyo inosangana nehupamhi hwekubuda mwero weiyo link index. Kana iyo sisitimu inodzikisira (kureva kuti, chaiyo yekutapurirana nzira inoderedza), iyo yekubuda nhanho yemidziyo ichawedzerwa.
Chiziviso chehushamwari: Ratidza kuti uise iyo RF siginecha ku6 ~ 9dB tilt inobuda mune inoshanda engineering application kuvandudza iyo nonlinear index (pasi penode) yetambo system.
