Final polish 0.5–1 μm diamond · MPO/MTP pads · slurries & tapes · custom die-cut discs
Monocrystalline and polycrystalline diamond lapping film for fiber optic connector polishing — LC, SC, FC and MU ferrules. Tight particle distribution keeps endface geometry (radius of curvature, apex offset, fiber height) inside IEC 61755 windows polish after polish. 1 micron lapping film and final-grade diamond film discs are stocked for fast shipment.
| Abrasive | Monocrystalline / polycrystalline diamond |
| Micron grades | 0.5, 1, 3, 6, 9, 30 μm (connector sequence) |
| Formats | Discs, sheets, custom die-cut for polishers |
| Backing | PSA or plain polyester |
| Typical applications | MPO/PC-12, MPO/PC-16, MPO/APC-16, MPO/PC-24, MPO/APC-24, FC/UPC, SC/UPC, ST/UPC, LC/UPC, MU/UPC, FC/APC, MT-RJ, E2000 — multimode & singlemode |
Ceramic Ferrule Connector Polishing — 4-Step Process
| Step | Micron | Mineral | Product | Pad | Liquid | Time | Lifetime |
| Remove epoxy | 30 µm | Diamond | D30 | 80 D | DI water | 30–35 s | >30 plates |
| Rough polishing | 9 µm | Diamond | D9 | 80 D | DI water | 30–35 s | >30 plates |
| Fine polishing | 1 µm | Diamond | D1 | 80 D | DI water | 35–40 s | >30 plates |
| Final polishing | 0.02 µm | SiO₂ | SO/ADS | 70 D | DI water | 30–40 s | >8 plates |
Diamond lapping film lifetime is over 30 plates and ADS over 8 plates.
Polishing pads for multi-fiber MPO/MTP connectors where uniform pressure across 12–24 fibers decides insertion loss. Pad hardness options match each polishing stage so array co-planarity stays within spec on automated polishers.
| Type | MPO/MTP polishing pads, rubber pads |
| Hardness options | Per polishing stage (rough to final) |
| Compatibility | Mainstream automated fiber polishers |
| Formats | Standard and custom dimensions |
| Typical applications | MPO/MTP array connector polishing |
Nano diamond slurry and suspensions for the final haze-removal step on connector endfaces and precision optics. Stable dispersion prevents agglomeration scratches; supplied ready to use or concentrated.
| Type | Nano / monocrystalline / polycrystalline diamond slurry |
| Dispersion | Water-based, agglomeration-controlled |
| Supply | Ready-to-use or concentrate |
| Formats | Bottles, bulk packaging |
| Typical applications | Connector final polish, precision optics |
Fine polishing tapes, flocked pile films, fiber adhesives and cleaning rollers — the consumables around the polish step that decide first-pass yield on fiber optic assembly lines. One supplier, one quality system, one RFQ.
| Range | Polishing tapes, flocked films, fiber adhesive, cleaning rollers |
| Micron grades | 0.5–9 μm (tapes) |
| Formats | Tapes, rolls, sheets |
| Backing | PSA or plain |
| Typical applications | Fiber assembly lines, endface prep & cleanup |
Complete consumables set for connector polishing lines: films, pads, slurries, tapes and adhesives from one factory — one RFQ covers everything.


GRISH has manufactured precision abrasives since 2002 in a 12,000 m² factory & laboratory with imported coating and converting equipment. Over 20 years of joint R&D with universities turned research projects into 49 invention patents — and GRISH co-authored 5 industry standards for polishing materials. Films, pads and slurries are produced and inspected in-house, so consistency and lead time stay under our control, not a middleman’s.
