End-capped assemblies allow for much higher transmitted powers by reducing the power density to a level below the damage threshold. Shaped end cap tips can be tailored to specific laser launch conditions and applications. Molex's Fiberguide proprietary laser polishing process minimizes surface imperfections and maximizes power handling. Additionally, high-power SMA and D-80 compatible connector options offer superior thermal management while minimizing connector stress for NA conservation. An epoxy-free cantilevered-nose design (available in select versions) can also minimize laser and heat damage to surrounding materials.

End-cap diameters and lengths are offered for select numerical apertures and fiber cores size but can be easily customized for various fiber types and specialized applications.

When selecting optical cable assemblies for power delivery systems, designers must consider the power limitations of the three main components of the cable assembly: the base material, the input connector, and the mode stripper (if applicable).
