All XSOF™ sites are ISO 9001:2015 registered and we integrate the standard into everything we do including our MRP system. While some use ISO 9001 as a marketing tool, we use it as a pillar in our management system and overall infrastructure. From first customer contact to final inspection to packaging and shipping, we document and verify that we are meeting or exceeding our customers’ expectations.

ISO 9001:2015

Our operators are well trained in ISO:9001 requirements, and together we deliver the highest quality products to our customers on-time and ready for use.

Quality Assurance

XSOF™ is the strategic combination of RSOF and TSOF, both excellent specialty fiber optics manufacturers and designers. XSOF™ stands for four things:

  • X – Excellent customer service
  • S – Stand behind every product and promise
  • O – On-Time Delivery
  • F – Feedback for continuous improvement

These values form the foundation for our company as well as our everyday operations and actions. They guide our team to push the boundaries of what’s possible in fiber optics manufacturing, as well as the standards of quality that we uphold. For more information about our Quality Assurance measures, check out our Quality Assurance page.
