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
Two versions of the MOA-3800 exists: singlemode and multimode. Optimized for use with EXFO systems and software, the MOA-3800 Variable Optical Attenuator (VOA) can add precise attenuation to four, eight or sixteen different singlemode or multimode fibers (each fiber can be set independently). An optional self-adjusting mode is also available, which automatically monitors and sets the output power to the desired level.
With its remote control capabilities using Standard Commands for Programmable Instruments (SCPI) over Ethernet, the MOA-3800 is the ideal solution for the following applications:
- bit error rate (BER) testing
- system characterization
- component or system loss simulation
- optical margin analysis
- WDM power balancing
