Optical cable for indoor and outdoor use in vital communication and emergency systems that need to be opertaional during fire. The cable has a patented design that ensures operation for more than 3 hours in fires up to 1000C. The cable is halogen free and flame retardant to protect against secondary damage to electronic equipment during and after fire. Outer sheath(1) is made from black UV-stabilized and weather resistant material and may be exposd for shorter periods to fluids such as diesel and mineral oils. The resistance to these fluids is according to IEC6081102-1. The cable is reinforced with a steel wire braiding. The fibres are protected in jelly filled loose tubes stranded around a central strength member to ensure optimum performace and long life. Each fibre and loose tube is colour coded for easy identification during splicing and termination. The outer sheath is marked to show fibre type and cable type.

An additional outer sheath is added for improved oil-and MUD protection. The sheath colour is GREY.
