Abstract: In June 2017 a new European regulation (Construction Product Regulation) became effective Subsequently, it became mandatory in Europe for all cables to be rated for their ability to resist fire before they can be used permanently in buildings. The test procedures are described in the European (Cenelec) standards EN 50399 (CPR tests) and the classification of the cables is defined in the standard EN 13501-6. The corresponding CPR classes of cables are mainly determined by measuring their vertical flame spread (FS), heat, and smoke release parameter. The tests will be performed by certified independent test laboratories (Notified Bodies). To be able to characterize the newly developed Flame Retardant cables, a brand new burn chamber was installed in the Corning cable development facility at the Corning Technology Center Berlin (CTCB). Intensive burn testing started in 2015. From the beginning a reference cable was used for the characterization of the burn chamber conditions. Especially, the vertical flame spread (FS) was monitored since it is very sensitive against any changes in the operating as well as environmental conditions. Comparative round robin tests in European test labs were performed which showed a systematically lower average flame spread in the order of 0.4 m, measured on the reference cable. However, test results achieved in other newly installed chambers confirmed a higher flame spread comparable to that measured at the beginning in our chamber. Long term monitoring (2015 – 2022) of the FS in our chamber revealed a gradual decrease of the flame spread by approx. 0.2 m. The following paper will prove that the observations mentioned above can be explained by a gradual change of the emissivity of the inner walls of the burn chamber by “aging.” The most prominent aging effect is the coverage of the originally shiny metall surfaces by a black soot.

Abstract: Recently demand has grown for high fiber count optical cables in places like data centers. Cables utilizing flexible ribbon technology have also proven to be very good options for data center applications because of their lower outer diameters and compatibility with mass fusion splicing. Many customers deploy cables in the European countries, outside the US and Canada. This necessitates the use of high-density fiber optic cables that not only meet the building codes of the US and Canada but also fulfill the fire performance criteria necessary for indoor installation in European regions. The 3456F flexible ribbon indoor/outdoor cable presented in this paper features a high fiber density compact design combined with UL-1685/FT4 and UL-1666 as well as CPR flame ratings. These features make the cable extremely versatile. The cable is suitable for the indoor and outdoor applications in the U.S., Canada, and the European countries. Beyond its impressive flame rating, the cable also passed various mechanical and environmental testing, per GR-20 and ICEA-696 specifications, all yielding passing results which will be shared in this paper.

About the Presenter: Eric Anderson is a Product Development Engineer for one of Prysmian Group’s Telecom manufacturing plants in Lexington, SC. He has four years of experience in the Telecom Industry. Prior to joining the Product Development group, Eric was a Process Engineer for the Lexington Plant Loose Tube Buffering Department. Eric earned his Master’s degree in Mechanical Engineering from the University of South Carolina.
