Case Studies
Fiber Infrastructure Expansion – Boston, MA
A major U.S. telecom carrier utilized Fiber Optical Test’s PMD testing platform during a 100G metro expansion. Our polarization scrambler and fast processing modules allowed the team to certify over 1,500 miles of fiber in half the expected time, helping them meet strict rollout deadlines.
Data Center Interconnect – Dallas, TX
A hyperscale data center operator adopted our PMD solution to ensure high-availability interconnects between campus buildings. The integration with their OTDRs allowed for simultaneous loss and PMD testing, improving accuracy and reducing total test time by 40%.
National Research Network – Calgary, Canada
A Canadian research consortium used our advanced PMD analysis tools to validate experimental transmission systems over legacy fiber routes. Our software’s adaptive trace filters helped visualize rare PMD spikes, contributing to groundbreaking findings in optical transmission.
