FTBx-3500 - Variable attenuator
Ideal for transceiver testing and system verification in demanding 24/7 production environments.
MOA-3800 - Variable optical attenuator
Single-mode and Multimode Variable Attenuator (VOA) can precisely add attenuation to four, eight or sixteen different optical paths; a Self-Adjusting mode is also available, which automatically monitors and sets the output power to a desired power level.
OSICS ATN - High-power variable optical attenuator
Combining industry-standard attenuator components and a broad attenuation range, the OSICS ATN brings you the power to operate throughout a large wavelength range
OSICS BKR - Variable back reflector
Variable back reflector designed to measure the effects of back reflections (return loss) on transponder prototypes
