市場上的網線種類繁多，很多用戶在挑選網線的時候都會一頭霧水。下面，就由小編總結四大主流網線的性價比哪個最強，這樣各位在選購網線的時候就不用怕選到不適合自己的產品了。

四大主流網線的性價比

從布線物理帶寬來看：物理帶寬越大，支持的傳輸速率就越高

CAT5E(100Mhz)< CAT6 (250Mhz)< CAT6A (500Mhz)< CAT7 (600Mhz)

從銅芯直徑來看：銅芯直徑越粗，傳導性能就越好

CAT5E(0.51mm)< CAT6 (0.57mm)= CAT6A (0.57mm)= CAT7 (0.57mm)

從理論最大傳輸率來看：數據傳輸率越高，則需要更大的物理帶寬

CAT5E(1200Mpbs)< CAT6 (2400Mpbs)< CAT6A (10Gpbs)< CAT7 (10Gpbs)

是否支持萬兆以太網應用標準：

CAT5E：不支持

CAT6：支持，但傳輸距離不能超過37米

CAT6A：支持，並滿足100米範圍標準

CAT7：完全支持

是否減少先對間串擾：這是布線系統穩定高速傳輸數據信息的最重要的基礎前提

CAT5E：沒有骨架結構

CAT6：採用十字骨架結構，減少線對間串擾

CAT6A：採用對鋁箔屏蔽外加鋁箔總屏蔽方式

CAT7：單獨線對鋁箔屏蔽外加公共編織網屏蔽層

線纜環路電阻(20℃時)：銅芯環路電阻越小，傳導性能越好

CAT5E：——

CAT6：155Ω/km

CAT6A：150Ω/km

CAT7：140Ω/km

容抗：容抗越小，說明電容的阻礙越小

CAT5E：——

CAT6：54nF/m

CAT6A：43nF/m

CAT7：42nF/m

阻抗：阻抗越小，越容易驅動

CAT5E：——

CAT6：100±15Ω

CAT6A：100±15Ω

CAT7：100±5Ω

NVP值：NVP值越高，表明電子信號在介質中傳輸的速度越快

CAT5E：——

CAT6：69%

CAT6A：76%

CAT7：81%

Four mainstream network cable cost

From the wiring physical bandwidth point of view: the greater the physical bandwidth, the higher the supported transfer rate

CAT5E (100Mhz)

Diameter from the copper point of view: the thicker the copper core, the better the conductivity

CAT5E (0.51mm)

From the theoretical maximum transmission rate of view: the higher the data transfer rate, you need more physical bandwidth

CAT5E (1200Mpbs)

Whether to support 10 Gigabit Ethernet application standard:

CAT5E: Not supported

CAT6: Support, but the transmission distance can not exceed 37 meters

CAT6A: Supports and meets 100m range standards

CAT7: Fully supported

Whether to reduce the first pair of crosstalk: This is the most important basic premise of the cabling system for stable and high-speed transmission of data and information

CAT5E: No skeleton structure

CAT6: The cross-frame structure to reduce the crosstalk between pairs

CAT6A: The use of aluminum foil shield plus the total masking

CAT7: Individual wire pair aluminum foil shield plus common braid shield

Cable loop resistance (at 20 ℃): the smaller the copper loop resistance, the better the conductivity

CAT5E: -

CAT6: 155Ω / km

CAT6A: 150Ω / km

CAT7: 140Ω / km

Capacitance resistance: the smaller the capacitance, indicating the smaller the resistance of the capacitor

CAT5E: -

CAT6: 54nF / m

CAT6A: 43nF / meter

CAT7: 42nF / m

Impedance: The smaller the impedance, the easier it is to drive

CAT5E: -

CAT6: 100 ± 15Ω

CAT6A: 100 ± 15Ω

CAT7: 100 ± 5Ω

NVP value: The higher the NVP value, the faster the electronic signal travels through the media

CAT5E: -

CAT6: 69%

CAT6A: 76%

CAT7: 81%
