Fibre optic polishing emery cloth

Fibre optic polishing emery cloth is a precision abrasive consumable engineered for the final termination and maintenance of fibre optic connectors. These cloths, often referred to as lapping film or polishing sheets, are available in micron-graded grits ranging from coarse (e.g., 30 µm) to ultra-fine (e.g., 0.3 µm) to achieve a scratch-free, low-loss end face. They are typically used in conjunction with polishing pucks and fixtures to ensure a consistent angle and pressure, critical for minimizing insertion loss and back reflection in single-mode and multimode systems.

These polishing cloths are indispensable in telecommunications, data centres, CATV, and FTTH installations where high-bandwidth optical networks demand impeccable connector performance. They are used in field termination kits, lab environments, and manufacturing facilities for cleaning and re-polishing connectors like LC, SC, ST, and FC types. The process ensures compliance with industry standards such as IEC 61300-3-35 for end-face geometry.

Our inventory includes subcategories such as aluminium oxide and diamond lapping films, with grit sizes from 12 µm down to 0.5 µm. Key article codes follow a pattern like "FOP-EC-12" for 12 µm emery cloth, "FOP-AL-3" for 3 µm aluminium oxide, and "FOP-DI-0.5" for 0.5 µm diamond film. These are available in sheets, rolls, or pre-cut discs for various polishing machines.

We offer express worldwide shipping and dedicated support from electrical and fibre optic engineers who can advise on grit selection and polishing procedures for your specific connectors and performance requirements. Our real-time pricing and technical documentation ensure you get the right consumable for a reliable, low-loss splice.
