Silicon Carbide Polishing Slurry for MT MPO MTP Ferrule Pre-Geometry and Fiber Height Control

Silicon Carbide (SiC) Polishing Slurry is a powerful and efficient abrasive choice for MT, MPO, and MTP ferrule pre-geometry and fiber height control, particularly during early-stage polishing where higher material removal is needed to level epoxy, protruding fibers, or uneven surfaces.

Why Use Silicon Carbide Slurry for MT/MPO/MTP Pre-Polish?

???? Typical Specifications

 When to Use Silicon Carbide Slurry

Ideal for:

• Initial ferrule shaping

• Epoxy removal

• Flattening MT ferrule surface

• Controlling fiber protrusion before final polish

Polishing Process Using SiC Slurry

✅ 1. Setup

• Use with Silicon Carbide or Diamond lapping film (15–3 µm)

• Apply film to flat platen or glass base

• Use appropriate polishing jig for MPO/MT type

✅ 2. Slurry Application

• Shake the bottle thoroughly before use

• Apply 2–4 mL of slurry evenly over the film

• Add water if needed to maintain flow and prevent drying

✅ 3. Polishing Parameters

✅ 4. Cleaning & Inspection

• Rinse connector thoroughly with deionized water

• Dry with lint-free tissue or clean air

• Inspect geometry using interferometer:

  • Radius of curvature

  • Apex offset

  • Fiber height (ideal: within ±50 nm)

Recommended Polishing Sequence (with SiC Slurry)

Best Practices

• Keep polishing area clean between stages

• Don’t reuse slurry to avoid grit contamination

• Always shake or stir slurry before use

• Avoid polishing too long with coarse slurry—it may damage fiber edges
