Regarding Cable, that is, cable certification and testing services, many people may not know what it is and what it is for. In fact, this thing is a very critical part in network wiring! Simply put, through professional instruments and equipment, a series of strict and specific standards tests were conducted on communication cables that had been laid, such as copper cables, optical cables, etc., and finally a proof of whether they can reach a given performance level is given, just like issuing a "graduation certificate" to the cable! This is very important for ensuring that the network can operate stably and data transmission smoothly in the future!
1. Test standards and types : Common test standards are TIA/EIA – what? Oh yes, it seems to be called ANSI/TIA now, and ISO/IEC and so on. These standards are like the "rules of the game" that must be followed during testing. Types include copper cable testing such as Cat5e, Cat6, Cat6A and even later, as well as single-mode and multi-mode optical cable testing. Different cables must use different testing methods.
2. Key test parameters : Do you know? It’s not just a random test, there are many tricks here! For example, attenuation – the situation where the signal becomes weaker and weaker, near-end crosstalk (NEXT), far-end crosstalk (FEXT), return loss (RL), bandwidth and other parameters. Each parameter must be carefully looked at and tested carefully. No matter which one does not work, it may affect the overall performance of the cable!
3. Test instruments and procedures : The instruments used are very professional, such as Fluke's DSX series, which seems to be a very famous brand. In the process, it is usually to prepare the cable information first, then connect the cables at both ends of the tester, start the test – wait for a while – the instrument runs the test steps by itself, and finally a report is released. You can tell whether it is qualified or not.
Provide global procurement services for weak current intelligent products!
4. Certification report : This report is not a piece of waste paper! It is "evidence" of whether the cable installation quality meets the standards, and contains detailed test results, usage standards, dates, who tested them, etc., during project acceptance. This is an indispensable thing, and it may not be accepted without it
5. Select the service process : First, you have to clarify your cable type and which level of standards you want to meet; find a qualified and well-known test service provider; Third, agree on the test time and specific test scope; they send someone to test, or you send the sample; Fifth, after getting the report, you have to check it carefully to see if there are any problems!
Q: Do home network wiring also need to undergo this certification test?
A: Generally speaking, if you are an ordinary family and do not have very high requirements for the network, you may just need to test it out; if your home is different from others, such as setting up a small studio, or having a very high requirements for network speed and stability, then doing a certification test will make you feel more at ease.
Q: Does passing the test mean there will never be any problem?
A: That's not necessarily true! Passing the test can only indicate that the test was a Cable certification testing service that met the standards at that time, but cables may age over time, or they may be accidentally damaged during use later, so regular inspections are actually necessary.
Personally, although cable certification testing services may increase some project costs, in the long run, it can discover what cables exist in advance – what? It is a hidden danger, which will avoid greater losses caused by the Internet in the future, so it is quite worth investing, but don’t look for those unprofessional small companies to test it casually, that won’t work!
