    Achieve -55dB Return Loss with Precision Final Polish Films

    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.

    ÅngströmLap® SEQUOIA Final Polish Film is the latest from the ÅngströmLap® line of films. It was developed to reduce single mode assembly production consumables cost while maintaining the most stringent manufacturing processes in the industry; therefore, lot-to-lot product consistency is assured, enabling you to achieve uniform precision polishes, keeping yields at their maximum. SEQUOIA Final Polish Film outperforms the rest. Fiber Optic Center recommends final films for optimum, single mode and multimode performance but for a more economical, multimode process, Aluminum Oxide films from ÅngströmLap® may be substituted as final films.
