Differences between CAT5E, CAT6 And CAT6A in System Performance And Ethernet Application(2)

Therefore, due to the difference between the two gigabit Ethernet standards at that time, the cabling performance requirements were driven. All integrated cabling manufacturers were urged to introduce Category 6 cabling systems with stronger anti-interference capability and better transmission performance than CAT5 cabling. Here's a brief description of CAT5E and CAT6 cabling system product performance differences:

1.CAT5E cabling physical bandwidth: 100MHz, CAT6 cabling physical bandwidth: 250MHz; (Note: the physical bandwidth is higher the higher the transmission rate)


1.CAT5E cable is usually 24AWG wire gauge (copper core diameter of about: 0.51mm) , CAT6 cable usually adopts 23AWG wire gauge (diameter of copper core is about: 0.57mm); (Note: the thicker the diameter of copper core, the better the conductivity and the smaller the signal attenuation on the line. In the PoE application area, 23AWG is better than 24AWG Energy transfer has absolute advantage)


1.CAT5E cabling theory to support the maximum data transfer rate of 1200Mbps, CAT6 cabling theory to support the maximum data transfer rate of 2400Mbps;

(Note: higher data transfer rates require more physical bandwidth)


1.CAT5E cabling does not support the 10GBASE-T 10 Gigabit Ethernet application standard, CAT6 cabling can support 10GBASE-T Ethernet application standards, but the transmission distance received limit, can not exceed 37 meters. (Note: Cat 6 cabling is still barely enough to meet the needs of 10 Gigabit Ethernet applications over short distances, which can not be supported by Cat5e systems.)


1. CAT6 cables generally use a cross-shaped structure to reduce crosstalk between pairs of (NEXT) near-end crosstalk performance index than without the framework of the CAT5E performance index (5-10dB) in the range of (1-100MHz) are higher than 5-10dB;

(Note: minimize crosstalk between pairs of cabling system is stable and high-speed transmission of data and information of the most important The basic premise)


Comprehensive comparison of the two levels of cabling system differences, six cabling system is not only in the physical electrical performance is much higher than the super five cabling system, but also in the data high-speed and stable transmission is also much higher than the super five cabling system. At the same time, with the continuous maturity of 6 types of cabling markets, the large-scale promotion of 6 types of products drives the production of 6 types of large-scale products so that the prices of category 6 cabling products are no longer much higher than the prices of super-5 types.
