AV-800 Optical Attenuator

  • attenuator

Item No.:AV-800


Optical Attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, there, therefore RB300 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)


1. Attenuation range 0dB ~ 30dB or 0~60dB.
2. Stepwise attenuating by circumgyrated dial: attenuating step 0.1dB/1dB/10dB
3. Linear attenuation module, high reliability
4. High attenuation accuracy, low insertion loss
5. Provide with the function of displaying dB and dBm attenuating value
6. Alternative function of 10 minutes Auto-off without operation.


1. Telecom Maintenance
2. CATV Maintenance
3. Comprehensive cable construction system
4. Optical instruments research and development
5. Optical communication education and lab testing
6. Other optical project.
