handhold optical variable attenuator

handhold optical variable attenuator
Product Detailed
Variable attenuator, handheld attenuator, attenuator Wavelength Range: 1260~1650nm Connector: FC/PC

Variable attenuator, handheld attenuator, attenuator

SPT-3303 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, SPT-3303 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

l   stepwise attenuating by circumgyrated dial- attenuating step 0.05dB

l   Provide with the function of displaying dB and dBm attenuating value

l   10 minutes Auto-off function can be activate and deactivate with keypad operation.

l   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

l  Portable, rugged, lightweight; Easy to use.

Applications

l   Telecom Maintenance

l   CATV Maintenance

l   Comprehensive cable construction system

l   Optical instruments research and development

l   Optical communication education and lab testing

l   Other optical project
