The W4 Mini enables precise monitoring of temperature, strain, displacement, pressure, tilt, and other optical sensors across the 1460nm to 1620nm optical spectrum, allowing engineers to integrate a high volume of sensors per fiber without the hardware bulk or high equipment cost traditionally required for such bandwidth. This efficiency facilitates real-time data acquisition in environments where space and energy resources are at a premium.

Key technical capabilities

• 160nm Scanning Range: Provides the breadth required for high-capacity sensor arrays in diverse fiber optic monitoring applications. 
• Low Power Consumption: Optimized for remote deployments and systems where energy efficiency is a critical operational constraint.
• Compact Architecture: Designed for integration into tight spaces without sacrificing the reliability of larger lab-grade interrogation units.

"The release of the new W4 Mini FBG Interrogator marks a significant milestone for Femto Sensing International as we continue to push the addressable markets for optical sensing technology," said Andrei Csipkes, CEO of Technica Optical Components, LLC. "By integrating a 160nm scanning range solid-state interrogator into such a low power consumption and compact form factor, we are providing our customers with unprecedented flexibility for complex monitoring applications while maintaining the high performance our brand is known for."

The W4 Mini Interrogator, operates fully within Femto Sensing International's Software Ecosystem:
