About CAT7驗證——CLASS F或者Fa測試FLUKE解決方案
七類CLASS F線纜認證測試標準在TIA的標準數據庫中是直接跳過，取而代之的是八類的通道測試標準，真正認證七類測試的是在ISO標準數據庫中，找到ISO11801 CHANNEL CLASS F或者FA，這就是標準的七類測試標準，測試頻率需要達到500MHZ，我們將通過實際測試，闡述七類測試的要點。七類測試之前，會被DTX-1800或者DSX5000系列強制認定自校準，這個過程和標準的設置基準是一樣的操作。
To test to 1 GHz,please look to the DSX-5000 CableAnalyzer which has been approved by Siemon.
TERA is Siemon's Category 7 connector used in Class F and FA cabling systems.It's a non RJ-45,shielded connector.Since it is not RJ45 based,you cannot use your DTX-PLA001 with DSP-PM06 or DTX-PLA002 Permanent Link Adapters.Likewise,you cannot use your DTX-CHA001,001A or 002 Channel Adapters.
由于七類是針對類似西蒙等標準大廠特殊的接口而設計的適配器，所以使用傳統的RJ45通道適配器或者長久鏈路適配器都是不支持的，必須使用TERA或者GG45的特定接口適配器才支持測試七類。
You need to order the DTX-TERA kit.You will need a DTX-1800 CableAnalyzer.If you have a DTX-1200 CableAnalyzer,it can be upgraded to a DTX-1800 CableAnalyzer by purchasing the DTX-1200 Enhancement Kit,Part Number:DTX-1218E.
Do NOT order just the DTX-PLA011 TERA Permanent Link Adapters.You will also need at least one DTX-CHA011 TERA Channel Adapter so you can Set Reference with the main and remote units.(Shown below)
Class FA is rated to 1,000 MHz(1 GHz).However,when you select a Class FA limit in the DTX CableAnalyzer,the test limit will stop at 600 MHz.Why?To answer this,we'll look to what the standard states.ISO/IEC 11801 Amendment 1 and 2 defers testing requirements to IEC 61935-1.
In IEC 61935-1 we see the following text:
6.7 Accuracy performance requirements for Level IV field testers over 600 MHz.The Level IV requirements shall apply to measurements of class FA cabling up to 600 MHz and pass/fail evaluation criteria shall apply.Measurement data over 600 MHz shall be provided for information only.Detailed requirements over 600 MHz are for further study.
Accuracy becomes a real issue above 600 MHz for field testing.At 1,000 MHz,the Insertion Loss accuracy is going to be at least+/-6 dB.
