1. Chigadzirwa Summary
SR812S ndeye yedu yepasirese CATV network yekuona inogamuchira ine network manejimendi transponder. Iyo pre-amp inotora ese-GaAs MMIC inokwidziridza uye iyo post-amp inotora GaAs simba kaviri amplify module. Yakagadziridzwa dhizaini dhizaini, yakasanganiswa nemakore edu ehunyanzvi RF dhizaini ruzivo, michina inowana yakakwira performance index. Iyo yakanakira modhi yeCATV network.
2. Chimiro
-Yakakwira mhinduro PIN photoelectric shanduko chubhu, 1G bandwidth dhizaini.
-Attenuation uye kuenzana kunogona kuramba kuchinjika knob mhandokana kuisa mhando.(Sarudzo)
-Simba rakapetwa kaviri kuburitsa, kuwana kwakanyanya uye kushomeka kwakaderera.
-Optical AGC kudzora, kana iyo yekuisa yemagetsi simba renji iri -7~+2dBm, iyo yekubuda level haina kuchinjika.
- Optional network transponder, tsigira NMS network manejimendi system.
