Whakaahuatanga Hua
1. Whakarāpopototanga Hua
Ko te SR812S to tatou kaikawe whakawhiti whatu whatunga CATV me te transponder whakahaere whatunga. Ko te mua-amp ka tango i nga GaAs MMIC whakakaha katoa me te pou-amp ka tango i te mana GaAs mana rua whakahiato kōwae. Ko te hoahoa ara iahiko kua pai ake, me o maatau tau nga wheako hoahoa RF ngaio, ka eke nga taputapu ki te tohu tohu mahi teitei. He tauira pai mo te whatunga CATV.
2. Āhuahira
- Whakautu teitei PIN ngongo whakawhiti whakaahua hiko, hoahoa 1G bandwidth.
- Ko te whakaheke me te whakaōrite ka taea te whakarite tonu te momo pukumomo whakauru ranei.(Kōwhiringa)
- Putanga kairuarua mana, teitei te whiwhi me te iti o te korikori.
- Mana AGC Optical, ina he －7～＋2dBm te awhe hiko whatu whakauru, karekau e rereke te taumata whakaputa.
- Ko te transponder whatunga whiriwhiri, tautoko i te punaha whakahaere whatunga NMS.
