The In-line Variable Optical Attenuator
The in-line variable optical attenuator (VOA) is manually-adjusted, used for precisely balancing the signal strengths in fiber circuits, or balancing an optical signal when evaluating the dynamic range of the measurement system.
Key Features
High Precise attenuation value Perfect environmental stability and reliability Low additional loss Flawless end face Wide attenuation range (variable)
Applications
Fiber optical telecommunication system FTTH, CATV, LAN Subscriber loop Fiber optical sensor Testing equipment
