Enhanced Solvent Resistance and Flammability Requirements for Harsh Environment and Industrial Optical Fiber Cables

Speaker Bio: Dr. Brian Risch, Materials Technology Manager, Prysmian Group (North Carolina, USA)

Abstract: This study examines the hierarchy of cable solvent resistance and flammability tests for optical fiber cables in harsh environment and industrial deployments. Although the flammability requirements and hierarchy are already well defined for optical fiber cables, standardized solvent resistance testing as specified in copper cable standards such as UL 1277 and UL-83 is not a current requirement for optical fiber cables even if deployed in identical environments to copper cables. New combined requirements for both flame retardancy and solvent resistance are proposed for industrial and harsh environment cables based on existing standards for copper cables. Various jacket materials are benchmarked against these oil and gasoline resistance standards.
