Taking carbon steel as an example, as shown in Picture 1, using a 1000w fiber laser cutting machine, for carbon steel materials thickness below 10mm, when the thickness of carbon steel is less than 2mm, the cutting speed per minute can be up to 8 meters. When the thickness is 6mm, the cutting speed is about 1.6 meters per minute, and when the thickness of the carbon steel is 10 mm, the cutting speed is about 0.6 to 0.7 meters per minute.

• Taking carbon steel as an example, as shown in Picture 1, using a 1000w fiber laser cutting machine, for carbon steel materials thickness below 10mm, when the thickness of carbon steel is less than 2mm, the cutting speed per minute can be up to 8 meters. When the thickness is 6mm, the cutting speed is about 1.6 meters per minute, and when the thickness of the carbon steel is 10 mm, the cutting speed is about 0.6 to 0.7 meters per minute.

It can be seen that when the thickness of carbon steel material is less than 2mm, customers who attach great importance to cutting speed can consider using 2000W fiber laser cutting machine, but the 2000W machine is much higher than 1000W in equipment price and operating cost. When the carbon steel material is larger than 2mm, the 2000W machine is not much faster than the 1000W cutting speed. Therefore, the 1000W fiber laser cutting machine is more cost-effective than the 2000W fiber laser cutting machine.

The cutting speed can directly reflect the efficiency of the fiber laser cutting machine. For cutting different materials with different thickness, the cutting speed will also change greatly. The thicker the thickness, the slower the speed!

Fiber optic WiFi vs. ADSL: which is better? https://en.itpedia.nl/2021/10/08/glasvezel-wifi-versus-adsl-wat-is-beter/ An unreliable or slow Internet can lead to slow transaction processing, such as bill failures, video conferences that often lag or buffer, or business orders that take too long to process. There are several options for fast internet. Two of these options are fiber optic WiFi and ADSL. Which of these two can better meet our need for fast internet?

i was going to ask what good it is having a cable that has power, but not the data center behind it.

i guess the situation is that the fiber optic cable also has power cables running along it too, powering the repeaters, and it's the power cables that might break. in this case, having single ended power would be very useful.

i'm most curious to know how power is sent. is this 48V dc? higher? how much? kV?
