Description:
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, there, therefore RY-VA3301 can be used in the digital system of communication devices (such as:
PHD, SDH) and also in the system of adopting analog modulation (CATV)
Feature:
Test wavelength: 850/980/1300/1310/1490/1550/1625nm
Test Range: -70dBm~+10dBm
Application
*Telecom Maintenance
*CATV Maintenance
*Comprehensive cable construction system
*Optical instruments research and development
*Optical communication education and lab testing
*Other optical project
