- Typical industry practice and manufacturer recommendations for similar optical attenuators is a 12-month interval. Many quality systems use a 1-year cycle; some low‑risk applications may extend to 24 months based on historical stability and usage. If you require accredited traceability or work under ISO/IEC 17025/9001, follow your quality plan—usually 1 year.
