談及CAT6A在萬兆以太網上的應用，就不得不提CAT6Ae。與CAT6A相比，CAT6Ae的產品性能更為優勝，具體表現在哪裡?
區別一：物理帶寬(物理帶寬越大，支持的傳輸速率越高)
CAT6的物理帶寬為250MHz
CAT6A的物理帶寬為500MHz
區別二：線纜環路電阻(線纜環路電阻越小，傳導性能越好，信號衰減就越小;NVP值越高，電子信號在介質中傳輸速度越快)
CAT6(20℃時)155歐姆/千米，NVP值：百分之六十九
CAT6A(20℃時)150歐姆/千米，NVP值：百分之七十六
區別三：支持萬兆以太網佈線標準
CAT6可支持10GBASE-T萬兆以太網佈線標準，但傳輸距離在37米以內，且存在很多缺陷
CAT6A可支持10GBASE-T萬兆以太網佈線標準，滿足100米範圍標準應用，無需額外的外部串擾測試
區別四：屏蔽效果
CAT6採用十字骨架結構，能減少線對之間的串擾
CAT6A採用對對鋁箔屏蔽外界鋁箔總屏蔽方式，能達到極好的康外部電磁干擾和抗線對間串擾的屏蔽效果，線對之間串擾在(1-250MHz)範圍內比CAT6均高出15-35dB

The difference between CAT6 and CAT6A in product performance
Difference 1: Physical bandwidth (the larger the physical bandwidth, the
higher the supported transmission rate)
The physical bandwidth of CAT6 is 250MHz
The physical bandwidth of CAT6A is 500MHz
Difference 2: Cable loop resistance (the smaller the cable loop resistance,
the better the conduction performance, the smaller the signal attenuation; the
higher the NVP value, the faster the electronic signal transmission speed in the
medium)
CAT6 (at 20°C) 155 ohm/km, NVP value: 69%
CAT6A (at 20°C) 150 ohms/km, NVP value: 76%
Difference 3: Support 10 Gigabit Ethernet cabling standard
CAT6 can support 10GBASE-T 10 Gigabit Ethernet cabling standard, but the
transmission distance is within 37 meters, and there are many defects
CAT6A can support 10GBASE-T 10 Gigabit Ethernet cabling standards to meet
standard applications in the 100-meter range without additional alien crosstalk
testing
Difference four: shielding effect
CAT6 adopts cross skeleton structure, which can reduce crosstalk between wire
pairs
CAT6A adopts the overall aluminum foil shielding method for aluminum foil
shielding, which can achieve excellent shielding effects of external
electromagnetic interference and anti-crosstalk between pairs. The crosstalk
between pairs is higher than CAT6 in the range of (1-250MHz) 15 -35dB
