Our Story
EXFO was founded by a team of fiber optic engineers who believed that test instruments should be as intuitive as the technology they measure. After years of using overly complex, bulky testers in the field, our founders set out to build instruments that telecom technicians could master in minutes, not days.
Headquartered in Quebec City, Canada, EXFO has grown from a five-person startup to a team of 480+ employees serving customers in over 45 countries. Our R&D center holds 85 patents covering OTDR measurement algorithms, automated fiber characterization, and network service assurance analytics.
What has not changed is our founding commitment: every instrument we ship must be field-ready, accurate, and backed by engineers who answer the phone when you need help.
