For several years Cat5e has been the standard for data networks. With transport speeds up to 100 Mbits/s, Cat5e cabling provides outstanding service and an affordable option for most data network infrastructures. Cat5e Cable Cat5e replaced Cat5 as a standard in 2001. The most common applications are 100BASE-T or “common” data networks and the increasingly popular VOIP systems. With 100Mbit/s capacity, Cat5e is the most common cable of choice used today. Cat5e Connectors Cat 5e and Cat5 network cable is connected with RJ45 connectors. (Pictured Left) Despite the superior performance over Cat3, there is still a distance limitation of 90m in length for horizontal cables.
