How does fluke dtx-1800 test cat7 network cable?

One day , Customer demand is testing 7 Quasilinear , Ask fluke DTX-1800 Cable certification Tester , Do you support ？
The answer is ： Fluke DTX-1800 The maximum bandwidth of the cable certification tester itself is 900MHz, and CAT7 The bandwidth requirement of the cable is 600MHz,900MHz Of DTX-18000 Full coverage 7 Network like 600MHz.
Since we support it 7 Class standards , Why is there no CAT7 What about your options , Here we need to briefly talk about the standard .
Generic cabling performance 、 The design standards refer to the following parts ：
1, international standard ISO/IEC11801
international standard ISO/IEC11801（ information technology —— User cabling system ） By the working group JTC1/SC25/WG3 Responsible for development , It defines the use area of 100 Ten thousand square meters and 5 The buildings of 10000 users and the communication wiring of the building complex , Including twisted pair wiring and optical fiber wiring , On 1995 Released in . Standard definition to 100MHz , Including the classification plan of wiring components and systems , Established the evaluation index “ class “Categories ””, And a single component , For example, cables or connectors must conform to the corresponding category , This is it. Cat3,Cat4,Cat5 etc. . also , In order to define the whole system composed of a certain category of components （ link 、 channel ） Performance level , The international organization for standardization established “ level (classes)”, namely Class A 、Class B 、Class C 、 The standard also defines a variety of cable types, including shielded and unshielded .
ISO/IEC11801 The second edition 2002 On 2002 year 8 month 13 The vote passed on the th ,2002 year 9 Monthly printing and publication became the official standard . This new standard defines 6 class 、7 Standards for class I cables , Bring revolutionary influence to wiring technology . The second edition ISO/IEC 11801 To regulate Cat5/Class D According to Cat5+ Redefinition .

2, North American standards ANSI/TIA/EIA568
ANSI/TIA/EIA568-A The purpose of the standard is to provide general guidelines for the design and installation of communication cables and connecting hardware in commercial buildings .568A yes 1991 First published in 568 Standard alternative procedures （568A yes 568 Extended version of ）.
TR-42.1 The branch of the committee is the committee responsible for building wiring Standards . In order to simplify the next generation 568-A standard , take 568B It is divided into 3 part ：
①TIA/EIA568-B.1： General ,2001 year ４ month １ Promulgated by the , replace TIA/EIA568-A.TIA/EIA568-B.1-1： General appendix １,2001 year 8 month 1 Promulgated by the , This appendix is right UTP and ScTP Twisted pair （ Four pairs of lines are wrapped with filter layers , Then use a layer of metal outer net ） The minimum bending radius is specified .
②TIA/EIA568-B.2： The second part , Balanced Twisted Pair Cabling System ,2001 year 4 month 1 Promulgated by the . This standard focuses on balanced twisted pair cables 、 Jumper 、 Electrical and mechanical performance specifications for connecting hardware , And component reliability test specification , Performance specification of field tester , Comparison methods between laboratory and field testers .
TIA/EIA568-B.2-1-2002（ISO/IEC11801：2002 Corresponding to ） The second part is the appendix of Balanced Twisted Pair Cabling System ２, namely ６ Class wiring standards .
③TIA/EIA568-B.3： The third part , Optical fiber cabling standard .
TIA/EIA568-A The content of the standard has been fully included in the new TIA/EIA568-B In the series of standards , Therefore, when quoting standards, directly quote TIA/EIA568-B Standard is enough .
in general 568-B Is from 1991 Published in ANSI/TIA/EIA568 The third version after the standard . Compared with the previous version, major changes have been made in the following aspects ： Parameter named 、 Establishment of test model 、 Redefinition of categories （ Remove the previous ４ Classes and ５ class , Replace with 5e and 6 class ）、 Introduction of new transmission media and interfaces （50/124 Micron multimode fiber 、 Miniaturized optical fiber interface SFF） etc. .
3、 European standards EN50173
European standards CELENEC EN50173（ information technology - Generic cabling system ） And international standards ISO/IEC It's consistent . however EN50173 Than ISO/IEC11801 Strictly . This standard has ３ A version , namely EN50173：1995、EN50173A1：2000、EN50173A1：2002.
Go back to normal , To achieve FLUKE DTX-1800 Cable certification test 7 Net like cable , Need a set of fluke special options ,DTX-CHA001,GG45 Test module .
