For improved signal transmission, use this lapping film from 3M to keep your fibre optic cable tips sharp. It features a diamond abrasive that's reliably rock hard, so it will cut through ceramic ferrules like a hot knife through butter. The film comes as a sheet with dimensions of 279.4 (L) x 229mm (W), so there's enough to go around for numerous jobs. A small 0.1μm grit size gives a smooth and uniform finish.

• Polyester backing keeps a firm hold on the abrasive
• Shelf life of 24 months enables long-term storage
• Can be used by hand or with a machine for versatility

• Communication industry
• Signal processing equipment

Each film type is colour-coded for easy identification. A green film, like this one, has a grit size of 0.1μm, while a white film has a 0.5μm grit size.
