Final Fiber Polishing Film

When a return loss of -55dB or better is needed with a controlled amount of undercut or protrusion, a special final polish film is required. This film maintains the geometry of the ferrule and improves the return loss and surface quality. Final Polish Films use silicon dioxide material and will polish the ceramic ferrule and glass fiber near the same rate. These films require only distilled water, and do not need messy slurries to meet back-reflection of -55dB or better for UPC, and fiber heights compliant with IEC Telcordia specifications.
