Fiber Optic Cable & Photonic Interconnects calculator

Scrap Fiber Cost Calculator

Fiber scrap can come from draw breaks, coating defects, cut-length errors, failed test results, damaged reels, or assembly rework. This calculator estimates the material exposure using scrapped length, cost per length, and any fixed sorting or disposition cost.

What this calculator does

  • Estimate scrap fiber cost from scrapped length, cost per length, recoverable share, and fixed disposition cost.
  • Use it when quantifying draw scrap, cut-length scrap, failed cable assemblies, damaged fiber, or rejected reels.
  • Estimates cost exposure from scrapped fiber, cable, or optical assembly length.

Formula used

  • Scrap fiber cost = scrapped length × cost per length × capture share + fixed handling cost
  • Per-length scrap cost = total cost ÷ scrapped length

Inputs explained

  • Scrapped fiber or cable length: Use the unusable length from draw, cabling, cutting, assembly, or test rejects.
  • Fiber or cable cost per length: Use cost per meter, kilometer, or foot that matches the length unit entered.
  • Scrap cost capture share: Use the share of material cost charged to the job, supplier, variance, or improvement project.
  • Fixed scrap handling or disposition cost: Add sorting, quarantine, rework evaluation, disposal, or material review board cost not captured per length.

How to use the result

  • Use it for scrap reviews, yield improvement projects, supplier claims, and quote yield assumptions.
  • It does not include lost capacity, customer penalties, or rework labor unless those costs are added separately.

Common questions

  • What length unit should I use? Use meters, kilometers, or feet consistently. The cost per length must match the same unit.
  • What should fixed handling include? Include quarantine, sorting, material review, disposition, disposal, or quality-engineering effort that is not charged per length.
  • Should recoverable scrap be netted out? Yes, reduce the capture share or cost per length if part of the scrap can be reused, recovered, or credited.
  • What decision does this support? Use the cost to prioritize yield work, justify process changes, or quantify the financial impact of rejected reels and cut lengths.
