These cables used in data transmission systems that work up to 155 Mbit/s. These cables are particularly preferred in the offices, buildings where many terminals are found. The outer sheath material of CAT 5e UTP cable is PVC for indoor application; black PE is for outdoor application and HFFR is free flame retardant compound which has low smoke density and no toxic/corrosive gases during a fire.
