Description
The GAOTek Variable Optical Attenuator for CATV is used for continuously variable optical signal attenuation. It device widely utilized for testing the optical system margin and linearity of CATV systems. It comes with convenient features including an optional auto-off function to conserve energy and being lightweight, portable, and easy to use. After being shut off, the system will retain the attenuating value and step.
Key Features
- Displays dB and dBm attenuating value
- 10 minutes Auto-off function can be activated and deactivated with keypad settings.
- After being shut off, the system will have stored the attenuating value and the attenuating step.
- Portable, rugged, lightweight;
- Easy to use.
