Integrated wiring test precautions

Integrated cabling system test is a commonplace problem, because of its position in the integrated cabling system, we still have to deeply analyze the problems that need special attention in the actual operation process, which is very important to the tester, but also a very important part of the integrated cabling system program.

Super Class 5 and class 6 integrated cabling system is the most widely used integrated cabling system in the system of more than 1000 points, which is widely used in the wiring system of office buildings, campus networks, campus networks, various intelligent buildings and intelligent communities, and even in the automated production system and industrial Ethernet has begun to be widely used. Because the actual data bandwidth of the user's various applications is not high, unless it is a system with very poor quality, the ordinary quality problems or even serious quality problems of most systems are generally hidden relatively deep, generally after several years or even more than ten years will be exposed, and this time has long passed the quality traceability period. Most users can only rely on redundant links and temporary repairs to maintain the upgraded large bandwidth applications, or simply scrap the original system and re-test the integrated cabling system to solve the problems left over from the early days. Replacing the system early will cause a budget loss, and since rewiring takes time, many users value the lost business time and associated profits more.

Selection of test standards for integrated wiring system

Small network generally choose 5 types of line system, the construction worker will generally do a on-off test after the completion of laying (to see whether the 8 indicators on the on-off tester are lit), or carry out a small batch of on-off test while construction, if there is no problem, you can "hand over". At present, all such applications can be fully supported only in 10M Ethernet (Class 3 lines can be met), so users often cannot find the hidden quality problems of the wiring system, because only the on-off test can not determine whether the network wiring system meets the requirements of the class 5 system. Even if there are serious quality problems will not be immediately exposed, most will wait until a few years later on some large bandwidth applications, will find the problem, and high-definition format large bandwidth video applications are not popular, but also because of the Internet bandwidth expansion speed relative to the growth rate of network user demand is quite slow, The lag of MAN construction also restricts the speed of local high-speed bandwidth video applications. According to this optimistic estimate, the fastest time for users to find serious quality problems in the wiring system is 3 to 5 years later.

For medium and large networks or some small and medium-sized networks with high reliability requirements, the planners and builders generally have some knowledge of quality detection of integrated wiring systems, and some users are even familiar with the test standards for integrated wiring quality acceptance such as the national standard GB50312-2007. Due to its own network structure is more complex, although not all, but some users of bandwidth consumption will be relatively large, such as VOD privileged users, especially data centralized users, because of the high quality requirements of the data center, the application speed is fast, only the test is not guaranteed that the link must meet the requirements of these applications.

So, small networks and ordinary user links do not need to do quality acceptance testing? Of course not, most of the problems of small users are that they are in a very passive position in the quality assurance system, because they do not understand the standards of quality inspection and acceptance, how to accept the integrated cabling system is generally "passive" to listen to the opinions of system integrators and engineering contractors (Party B), installation engineers, as long as the cable link is connected, That means the link quality is qualified.
