Description
This tight buffered OM4 bulk fibre from Connectix is CPR-rated to Cca-s1a-d0-a1, providing an excellent reaction to fire and exceeds BS6701:A1 minimum requirements.
It can be used both indoors and outdoors in applications such as LAN and WAN backbones, tray pathways and backbones in data centres.
The outer sheath is made from UV stabilised, water and moisture-resistant LSZH (low smoke zero halogen) material, making it well suited for shorter outdoor runs.
