STRIP-FORCE TEST GUIDE

Optical Fiber Coating Strip Force and Strippability

A strip-force result is useful only when the coated fiber, conditioning, tool geometry, test motion and observed failure mode are documented together.

01

Define the coated-fiber test article

Record the glass diameter and design, primary and outer coating system, coating dimensions, cure process, production history and any aging or environmental exposure. Results from different coating constructions should not be treated as interchangeable.

02

Specify the stripping method and geometry

Document whether removal is mechanical, thermal-mechanical or another agreed method, together with the tool or blade condition, strip length, pull direction, alignment, speed and fixture. Do not compare a coating pullout test with a strip-force test as though they measure the same event.

03

Control sample conditioning

Define temperature, humidity, conditioning time and the interval between conditioning and testing. If hot, cold, wet or aged behavior matters, use a controlled sequence and compare it with an unexposed baseline.

04

Record the force trace and failure mode

State how peak, average or another reported force is calculated and retain the force-displacement trace where practical. Also inspect for coating residue, glass damage, fiber breaks, layer separation and inconsistent initiation because one force number cannot describe the entire stripping result.

05

Validate the downstream operation

Confirm that the selected process leaves the fiber suitable for the intended splice, connector, recoating or assembly step. Include cleaning, surface inspection and any required optical or mechanical verification instead of using strip force as the sole acceptance criterion.

Prepare these details for a productive material discussion.

  • Fiber design, coating system and dimensions
  • Strip method, tool condition and geometry
  • Strip length, speed and alignment
  • Conditioning and exposure history
  • Force calculation, failure modes and downstream checks

Questions to clarify before evaluation

Is the lowest coating strip force always best?

No. The result must be balanced with coating integrity, handling, environmental retention, residue, glass protection and the requirements of the downstream operation.

Can strip-force values from different laboratories be compared directly?

Only when the fiber construction, conditioning, tool geometry, strip length, test speed, calculation and failure criteria are sufficiently aligned.

Does one strip-force value prove clean and damage-free removal?

No. Inspect residue, glass damage, fiber breaks and layer separation, and verify the intended splice, connector or assembly process.
