IEC 62343:2017

Overview

IEC 62343:2017 - Dynamic modules: General and guidance is the second edition (2017) international standard that defines and guides the IEC 62343 series for optical dynamic modules. It applies to all commercially available dynamic optical modules and devices, describing the product scope, terminology, fundamental considerations and recommended approaches. The 2017 revision updates the 2013 edition and notably adds definitions for the wavelength selective switch (WSS). IEC 62343:2017 establishes a framework for consistent requirements covering operation, reliability and environmental properties, and helps purchasers select high-quality dynamic module products.

Key topics

• Scope and terminology: Clear definitions for dynamic modules and device subtypes (e.g., DCE, TDC/DCDC, DGTE, OCM, WSS) and terms used across the IEC 62343 series.
• Dynamic behavior: Guidance for handling transient and dynamic functions such as tuning, switching, configuration and continuous optimization performed by electronics, firmware or software.
• Series structure: Framework for a complete set of standards:
  • Part 1: Performance standards
  • Part 2: Reliability qualification
  • Part 3: Performance specification templates
  • Part 4: Software and hardware interface standards
  • Part 5: Test methods
  • Part 6: Design guides
• Performance and testing: Coverage of performance templates, test methods, performance standards and pass/fail considerations to ensure consistent measurements and interoperability.
• Reliability & environmental requirements: Uniform approaches for reliability qualification and environmental properties to be implemented in specific DM standards.
• Interfaces: Guidance on hardware and software/firmware interfaces for integrated optical modules (optical components + printed wiring board + control software).
• Safety & EMC: Notes that optical radiation safety (optical power considerations) is handled by IEC TC 76; electromagnetic compatibility guidance is referenced for drafting EMC requirements.

Applications and users

IEC 62343:2017 is practical for:

• Manufacturers and designers of dynamic optical modules (WSS, ROADMs, VOAs, OCMs, dynamic equalizers) to align product requirements and testing.
• Purchasers and system integrators specifying and selecting high-quality dynamic modules for optical networks.
• Test laboratories and certification bodies developing test plans and reliability qualifications.
• Standards committees and technical writers creating part-specific standards within the IEC 62343 series.
