                                                                                                                                                                                                              市面上的網線制作工藝參差不齊,水平有高有底。那么我們該如何區分網線質量的好壞呢。

                                                                                                                                                                                                              剝網線——看絞距(不需要任何儀器)

                                                                                                                                                                                                              眾所周知,網線內是由四對雙絞線相互纏繞組成的,而四對雙絞線絞的越密,屏蔽性能越好,抵消外來干擾的能力也越強,網線的質量也就越好,如Cat6網線的絞距比Cat5e網線的絞距密集,其性能更優。不過對于屏蔽網線來說,網線內已有屏蔽層,無需看絞距,但對于非屏蔽網線來說,我們可以使用剝線鉗將網線剝開看四對雙絞線的絞距。
                                                                                                                                                                                                              剝纖芯——看材質

                                                                                                                                                                                                              在剝開網線的同時,我們可以再次使用剝線鉗將纖芯的外皮剝開查看纖芯材質是否為無氧銅。無氧銅的纖芯質地柔軟、色調亮黃,在光照的反射下,纖芯剖面會反射出金黃色光澤;若是剖面泛白且質地較硬,那么可能是雜銅,若是剖面亮白且質地非常柔軟,那么可能是銅包鋁。

                                                                                                                                                                                                              雖然鍍銅、雜銅、銅包鋁、銅包鋼、銅包鐵等導體材質的網線價格比無氧銅的網線價格便宜,但無氧銅的含氧量極低,基本無氫脆現象,不容易被氧化,使用壽命長;且其柔韌度高、抗拉力好,具備良好的延展性,彎曲不容易斷裂;與其同時,導電性良好,信號衰減小,能夠保障電氣設備在額定功率下工作,信號穩定順暢的傳輸。

                                                                                                                                                                                                              是否通過福祿克測試是判斷網線好壞*重要的標準之一。一般來說,質量好的網線都能經過福祿克測試,您可以在購買網線時詢問商家是否能夠提供福祿克測試報告。其中福祿克測試包含了鏈路測試、信道測試、單體測試。
