Distributed Raman Fiber amplifier EA2000RM series has a low effective noise index, adjustable gain, gain flatness, structural standards, high reliability.
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.
