ABSTRACT:
Methods and systems for marring the surface of a fiber optic substrate by pressing a length of the substrate against an elongate support with at least one roller and causing relative lengthwise movement between the roller and support with the roller pressing the substrate against the support and the roller rolling along the substrate. One of the roller and support may have an abrasive surface for marring the substrate during such relative lengthwise movement between the roller and support. Alternatively, the abrasive surface may be on a sheet supported by the support.
