How to choose the right network module?

[Tylerrr]

In the network, Switch Port with the computer network adapter RJ-45 port to connect major in two ways. Directly through a network cable is connected, mainly suitable for short distance from the circumstances, such as switches, placed the office; another way is through the information module to connect. Very often, the switch is on the network-centric, and office far apart, when the general practice is that arising from the switch cable to connect offices, will be connected with the information module, and then re-use the information module and the twisted-pair connected to the computer. This is the basics of the network module but I want to know how to select the most best suited network module for my network.

The cost differences between true and false blocks are very large, so the retail prices are also a greater difference. Good quality module are little costlier compared to the bad quality module. Grasp the approximate price range, if the merchants offer relatively low, then it is surely the product of poor quality; if a higher offer, you can try to counter-offer, to see how much the lowest acceptable, if the final price also relatively low, it means the same bad product; if the final selling price and the price of genuine consistent, then it is the more likely authentic.

I can understand the network module into a transit point for information. It is mainly by the panel, the installation boxes, and information outlets of three parts. Give a popular example, when we are in the decoration, outdoor telephone households are generally received when the wall of a small box, and then via a telephone line jack on the box and telephone to link. The same is true of network module, install the boxes embedded in the walls and information outlets through the clamp is fixed, and the external panels can be cast.

To judge from the appearance of packaging products, good or bad is the most direct method. Although the product will not necessarily be ugly with ugly packaging, but the majority of the packaging with the ugly is ugly product. Module packaging are generally sealed with plastic paper, thick texture, good toughness, try to remove the module which requires a larger edge; on the contrary the poor quality of packaging will be touched in their hands feels thin, and toughness is not enough.

In our market, the most common types of information modules AMP Ultra-5 as an example, its packaging painted silver print handwriting clear, neat, very uniform and shiny, while the counterfeit product there is no gloss, bleak.

The quality of products will be shown in every detail on the product. To judge from the outside at the same time, we can open the information module, to see the internal working of the printed circuit board. A good product solder joints should be smooth, tidy line; while inferior products on the due process defects in solder joints will be different sizes, very messy, the surface is very rough.

In general, good information module outside the plastic part of the quality of more substantial, the surface smooth, and the color is the word, front-end of the socket connection with the crystal with very good head. If the external surface quality rough, there is chromatic aberration, with the jack size is not good. This is illustrated in the existence of quality problems.
