1. Auto-off within 10 mins no-operation

10 minutes Auto-off function can be activate and deactivate with keypad operation.After off the instruments, attenuation value and step can be memorized until open the instruments next time.

2. Diverse Applications

The product can be used in the digital system of communication devices (such as, PHD, SDH) and also in the system of adopting analog modulation (CATV).

3.Attenuating value can be displayed

Provide with the function of displaying dB and dBm attenuating value, attenuation step from 0.05dB, you can control the accurate attenuating value through the LED panel easily.

4.Well package

Every product is packaged with instruction book and power supply by customized boxes , provide full protection against damage.

Attenuator Application

The handhold optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, therefore it can be used in the digital system of communication devices (such as, PHD, SDH) and also in the system of adopting analog modulation (CATV).
