Fiberoptic (5MHz) Modulator - NanoSpeed™

5ns rise/fall, 40dB isolation, 1dB low Loss, high optical power
  • No Moving Parts
  • High Reliability
  • Solid-State High Speed
  • Low Insertion Loss
  • Epoxy-Free Optical Path
  • Low Power Consumption
  • Simple Driver



The NS modulator provides a fixed sine wave (5MHz) light intensity modulation with depth adjustable up to 100%. The NS modulator is designed to meet the most demanding operation requirements of ultra-high reliability and fast response time with minimum mechanical footprint. This device comes with a miniature integrated driver that only requires a 5 V power supply.

The VOA is available in either normally-transparent or normally-opaque configurations.
