現在組建的網絡一般都採用5類以上的雙絞線，超五類網線更是成為主流網線。但是，有一些生產廠商出售假的雙絞線，謀取顧客的利益，那麼，如何分辨真假超五類網線?

1、包裝：超五類網線標有CAT5E字樣每箱應該是305米(1000英尺)，包裝不是305米一箱的可能不是網線。

2、線上面的標識：正規廠家的產品標識上定標有長度，做工程時方便識別1箱線用了多少米，還剩多少米線。

3、萬用表測試：國標網線305米單芯電阻為28歐姆左右，市場上的假超五類網線電阻有的甚至達50歐姆，傳輸距離縮短差不多1半。

4、網線材料：有的劣質網線4對中有2對銅線2對銅包鐵線，用在電腦網絡問題不大，用在監控系統就會產生干擾，用磁鐵吸一下就可以識別。

5、線絞密度：雙絞線線絞的密度應該接近1CM絞一下。

3、Multimeter test: GB 305 meters single-core resistance of 28 ohms or so, some of the fake ultra-five types of network cable resistance even up to 50 ohms, shorten the transmission distance of almost 1 and a half.

4、The network cable material: Some of the poor network cable 4 pairs of 2 copper pairs of 2 copper clad iron wire, used in computer networks is not a problem, used in the monitoring system will produce interference, the magnet suck it Can be identified.
