How to choose a switch?
Anyone who has worked in the optical communication industry should know that in the process of optical communication infrastructure construction, there are some things that cannot be without, such as jumpers, splitters, connectors, adapters, etc., and there are switches and media switches. A switch with one light and one electricity is a media switch.
There are many ways to classify switches, but for our users, we only need to pay attention to the relevant classification methods when buying and purchasing switches. That is, you know what kind of switch you should look for. Are you two?
Classification of switches
Generally speaking, the first thing that our switch manufacturers ask customers is what kind of switch they need. The style is the installation method, there are three installation methods. Rail type (DIN RAIL), desktop type (DESK TOP), and rack type (RACK TYPE), just choose directly according to the specific use.
How to buy a switch?
When choosing a switch, pay attention to what your specific requirements are. Where does the switch need to be used and how is the environment used? Extreme operating temperature? Are there any requirements for adapting to the environment? It’s like buying a computer. If it’s used to play games, or the work is related to programming and design, the computer requirements are absolutely different from those used to track dramas and listen to music. It can be used in a low-demand environment with high configuration. , But definitely not to save money to use low-configuration switches in high-demand environments, you can try if you don’t believe it, don’t cry when something really goes wrong, just spend money to buy lessons. So the best way is to use what kind of pot with what kind of lid. When buying, you must remember not to buy a fake industrial machine to save money. It's not that I bought a toy similar to children's RMB, but that I used industrial switch money and didn't do what I should do.
How to distinguish true and false industrial switches?
Where there are fake industrial switches, there are real industrial switches. What is a real industrial switch? What is the difference? The fake industrial switch has the hardware that the real industrial switch should have, but with low-profile software, the white point is high imitation. Real industrial switches are processed with three preventions during production, dustproof, shockproof, moisture-proof, and ventilation treatment, so the use environment requires a lighter range, the working temperature is -40℃-85℃, and the use time is also Longer, the general warranty time is 3-5 years, four (one 1) Sichuan (three 3) light (玖9) hair (捌8) Opticombine (玖9) production (2) (7) delivery ( Three 3) Change (Lu 6) machine (3 3) pass (zero 0) the CE, ROSH test standards, just use it with confidence. The fake industrial switches on the market have a working temperature of 0-70℃, or a slightly better -20℃-70℃, and the shelf life is only one year. The price is of course that our industrial switches are expensive. It depends on the situation. If the requirements are high, choose a real industrial machine. If there is no requirement, especially to buy a temporary replacement, there is no need to pursue a high-priced real industrial machine.
Another very important factor is speed, let's continue next time!
