Variable Optical Attenuator (VOA)
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
Applications
Optical passive component test
Fiber communication on system test
