High-Density Variable Optical Attenuator

Building on over 30 years of industry leadership and innovation in programmable optical attenuation, VIAVI Solutions has developed the highest density optical attenuation module in its class.

Based on a proven MEMS mirror design, the mVOA-C2B delivers ultra-low insertion loss (IL), return loss (RL), and polarization dependent loss (PDL), with exceptional repeatability, accuracy, and long-term stability.  

The mVOA-C2B is a dense form factor attenuator with LC connectors that allows for up to 96 independently-controlled attenuators in a single 3U MAP-300 mainframe, ideal for network emulation test systems. It is available in configurations of 4, 8, or 12 attenuator devices per module. It is a compact, hot-swappable cassette designed for use within the VIAVI MAP ecosystem, a modular, high-density test and measurement platform for lab and production environments.

Key Benefits

• Industry-leading density — up to 96 attenuators in a single 3U chassis
• Ultra-low insertion loss to minimize loss budget utilization
• High accuracy and repeatability to reduce measurement uncertainty
• Fast transition speed and settling time to reduce testing time
• Flat spectral response to reduce wavelength-dependent uncertainty in CWDM and DWDM applications
• Low backreflection to reduce instabilities due to reflected light
• Optional built-in wavelength-calibrated power meter reduces uncertainty by eliminating external connections
• High input power capability for EDFA testing and multi-wavelength applications
