The Vytran PTR-200-MCM-200 is a modular fiber optic recoating and proof testing system engineered for precision splicing and optical component qualification. It delivers consistent recoat geometry and reliable mechanical verification through selectable recoater and proof test configurations, accommodating fiber diameters up to 900 microns and supporting both acrylic and polyimide coating processes.
