1. CAT5E Wiring Physical Bandwidth: 100 MHz, CAT6 Wiring Physical Bandwidth: 250 MHz;

Tips: Higher physical bandwidth, the higher transmission rate

2. CAT5E cable usually adopts 24AWG gauge (copper diameter of about 0.51 mm), CAT6 cable usually adopts 23AWG gauge (copper diameter of about 0.57 mm);

Tips: In the upper transfer from 24 Ave to PO application in the region of 23AWG, the copper leading diameter, better conduction performance, reducing signal attenuation on the line, is an absolute advantage.

3. CAT5E has a maximum data transfer rate of 1200 Mbps in theory, and CAT6, in theory, supports a maximum data transfer rate of 2400 Mbps;

Tips: The higher the rate, the higher the physical bandwidth

4. CAT5E wiring does not support the 10GBASE-T Gigabit Ethernet application standard, CAT6 wiring can support the 10GBASE-T Ethernet application standard, but the transmission distance is limited, not to exceed 37 meters.

Tips: Category 6 wiring system, capable of meeting the needs of short-range Gigabit Ethernet applications, no more than five systems can be supported.

5. CAT6 cable is usually to reduce the crosstalk between the lines with cross structure, and near it (NXT) end crosstalk performance index in the range of 5–10 dB near CAT5A performance index (1- 100MHz);
