Unlike many vendors who force hardware obsolescence, EXFO offers a Extended Support Program for legacy products (5+ years post-EOL) including critical security patches and repair services, though at a premium cost.

Cost Consideration: Premium support costs roughly 15-20% of the original equipment price per year. For a $20,000 OTDR, that’s $3,000–$4,000 annually.

When self-help fails, physical service is required. EXFO operates a centralized RMA (Return Merchandise Authorization) system.
