![]() This is because, aside from cost, Cat6 cables can handle up to 10Gb of data with a bandwidth limited to 164 feet. ![]() What is a Cat6 Cable?Ĭat6 cables were introduced a few years ago and have become the primary backbone of networks. This interference can slow internet speeds and the quality of the connection. Crosstalk is the electromagnetic signals that come from Cat cables when many of them are close to one another and within a networking hub. Cat5E cables became standard around fifteen years ago and have improved performance over its predecessor, which includes up to ten times faster speeds and a greater ability to traverse long distances without being impacted by “crosstalk”. Even though Cat5 cables can handle up to 10/100 Mbps at 100MHz bandwidth, the newer Cat5E cables are quite faster. What is a Cat5 Cable?Ĭat5 cables have started to become obsolete in recent years due to its limitations and have since been replaced with Cat5E and Cat6 Cat7, Cat8 cables. ![]() ![]() These Ethernet cables are used for a variety of applications but are mainly used as network cables by connecting servers to modems and ISP’s. It later expands the findings to PoE Plus scenarios.Computer networking and technology have advanced greatly in recent years, and therefore, have led to the introduction of Cat 5 and Cat 6 network cabling, among others. The paper then calculates long-term savings, in electricity costs, that will be gained by the use of Category 6A rather than Category 5e cabling. In the case of the wireless access point, approximately 201 milliwatts of power were dissipated on the Category 5e circuit and approximately 137 milliwatts on the Category 6A circuit. ![]() In the case of the VoIP phone, on the Category 5e circuit approximately 82 milliwatts of power were dissipated, while on the Category 6A circuit approximately 56 milliwatts were dissipated. The performance characteristic under test was DC resistance, and the practical result of a cable's DC resistance in these setups is power dissipation.įor both devices, 328-foot cable runs of both Category 5e and Category 6A were deployed. A paper authored by General Cable data-communications products engineer Rob Gould makes the case for the use of Category 6A cabling rather than Category 5e cabling for applications in which Power over Ethernet (PoE) will be employed.įocusing primarily on the original 802.3af PoE specifications, but also considering the more-recently defined 802.3at PoE Plus specs, the paper provides documentation of testing under which Cat 5e performance was compared to Cat 6A performance supporting a VoIP phone drawing 4.93 watts and a wireless access point drawing 7.5 watts of DC power. ![]()
