1. Kakaretso ea Sehlahisoa
SR812S ke seamoheli sa rona sa bokahohle sa CATV sa marang-rang se nang le transponder ea taolo ea marang-rang. Pre-amp e amohela all-GaAs MMIC amplify le post-amp e nka GaAs power double amplify module. Moralo o ntlafalitsoeng oa potoloho, hammoho le boiphihlelo ba meralo ea RF ea lilemo, lisebelisoa li fihlella index ea ts'ebetso e phahameng. Ke mohlala o loketseng bakeng sa marang-rang a CATV.
2. Tšobotsi
- Karabelo e phahameng ea PIN ea phetoho ea lifoto tsa motlakase, moralo oa bandwidth oa 1G.
- Attenuation le ho leka-lekanya e ka ba mofuta o tsoelang pele o fetolehangkapa kenya mofuta.(Ho ikhethela)
- Phallo e habeli ea matla, phaello e phahameng le khopamiso e tlase.
- Taolo ea Optical AGC, ha matla a ho kenya a le －7～＋2dBm, boemo ba tlhahiso ha bo fetohe.
- Transponder ea marang-rang ea boikhethelo, ts'ehetso ea tsamaiso ea marang-rang ea NMS.
