各位大蝦: 請問 ETL 網(wǎng)絡(luò)線認證時測試哪些項目?還有: 衰減值/100米,只測100米的嗎?還是20米衰減可過也可通過認證?

比如: FTP 28AWG ,FTP 26AWG 衰減當然和FTP 24AWG值不一樣.

ETL認證網(wǎng)絡(luò)線是認證100米,沒有其它長度

It's according to what specification you request.

For example , if ANSI/TIA/EIA 568B.2 was specfiy to test Unshielded Category 5e erally, They will test DC Resistance , Mutual Capacitance Attenuation , NEXT , FEXT , Return Loss, Input Impedance .......

They will also test Attenuation Skew... @ 40 ⁰C & @60⁰C
