如何區分水晶頭的好壞? | |
The crystal head is the interface that provides sound and data transmission in Structured Cabling, and it is also one of the most indispensable cabling infrastructures in Structured Cabling. How to distinguish between good and bad crystal head? 4. Gold plating thickness: The crystal head needs to be plugged and unplugged continuously, which is easy to wear the gold-plated layer on the plug. Therefore, the gold plating thickness needs to reach 50μ and the number of plug-in and pull-out times exceeds 1,000 to meet the standard. 5. Shell material: A good crystal head is made of high-quality PC material, with a transparent and smooth appearance, a small coefficient of thermal expansion and contraction, a precise size, good stability, and can adapt to complex and changeable environments, and has a relatively long life. 6. Shrapnel: The shrapnel that locks the crystal head and the socket must have a certain degree of toughness. If the shrapnel is moved forward to 90°, the shrapnel will not be broken, and it will return to its original shape and the elasticity will not change. In addition, the number of times the shrapnel is bent should not be less than 15 times. At present, most crystal heads are not designed for line compensation, especially crosstalk compensation. With the arrival of the 5G era, 10 Gigabit Cat.6a has become popular, and it will be more appropriate to choose a jumper plug with crosstalk compensation. * * * * * * LIV is a professional data center to set up a company, with a group of professional team intimate attention to customer requirements, and provide quality services.
