    Diamond Lapping Film

    Diamond lapping films cut and polish the hard ceramic ferrules and the softer fibers close to the same rate, easily controlling fiber undercut or protrusion. Diamond also helps assure the ferrule geometries meet the Telcordia GR 326 version 3 specifications, and leave the ferrule in a condition ready for the final polish film. Diamond is always recommended for the intermediate steps of machine polishing of single mode or multimode ceramic connectors, and for single mode hand polishing of ceramic connectors. When stopping at a diamond of 1um or less, a good surface finish results with great geometries, but with a return loss of -35 dB at best. If back reflection of -55 dB or better is required, see our Final Polish Films.

    Fiber Optic Center can supply detailed polishing instructions for most commercially available fiber optic polishing machines and offers both ÅngströmLap® and 3M Diamond lapping films. ÅngströmLap® SEQUOIA™ Long Life Diamond Film is the long life diamond film which offers twice the working life of standard diamond films, therefore cutting your overall diamond lapping film consumables cost in half. During the manufacturing process, proprietary quality control steps are implemented, ranging from raw materials selection to final QC and testing. SEQUOIA Diamond films, designed to last well over 10 cycles, are at a level above other diamond films available today. Please contact Fiber Optic Center with any request.
