PM Variable Optical Attenuator (PMVOA)
Descriptions
This Variable Attenuator uses collimator lens technology enabling the user to change attenuation through the twist of a top mounted screw. Use this variable attenuator to simulate the loss in a fiber system or testing your system’s dynamic range.
Features
Wide attenuation range
High precision
Low original loss
High extinction ratio
Applications
Optical passive
component test
Fiber communication on system
test
Optics lab use
