Deployment & Qualification
Spare & Replacement Planning
Balance availability, lead time, commonality and product lifecycle.
Overview
Spares should reflect deployed quantities, failure exposure, replacement time, site criticality and the number of distinct link types.
Key planning checks
- Group truly interchangeable requirements without hiding differences.
- Maintain traceable known-good spares for critical links.
- Consider distributed versus central stock.
- Track product changes, end-of-life notices and replenishment lead time.
NRCube review note
Keep the unknowns visible
A spare is useful only if its coding, optical specification and topology match the failed position.
