Cheap fiber optic attenuator handheld variable optical attenuator, attenuate 2-60db

Cheap fiber optic attenuator handheld variable optical attenuator, attenuate 2-60db    It can attenuate 2-60dB     Contact information       Please contact Super Sales Engineer: Sophia Yin   Tel: +86 18603007473   Skype: sophia.hsv         Product Description   HSV-303 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, HSV-303 can be used in the digital system of communication devices (such as: PHD, SDH)
and also in the system of adopting analog modulation (CATV)     Main Features
stepwise attenuating by circumgyrated dial: attenuating step 0.05dB
Provide with the function of displaying dB and dBm attenuating value
10 minutes Auto-off function can be activate and deactivate with keypad operation.
After off the instruments, the system will have the memorizing of the attenuating value and the
attenuating step, in order to restore the system back to the previous shut down state when open
the instruments next time
Provide with the function of displaying dB and dBm attenuating value
Applications
Telecom Maintenance
CATV Maintenance
Comprehensive cable construction system
Optical instruments research and development
Optical communication education and lab testing
