Who has used Unicom's 3M fiber broadband? How do you feel?

According to the laws of physics, the propagation speed of electric field is similar to that of light, so there is not much difference in theory. But in my personal experience, the ping value of optical fiber is indeed much lower than that of cable (the lower the ping value, the better). If you are in the south, it is recommended to use telecommunications, because the equipment in the south telecom room is better connected. In addition, if you are an online game player, you should also consider the area where your game is located. If the network you play is the same as the game network provider (that is, Telecom, Netcom or Tietong), the ping value will be very, very low, and the probability of getting stuck will be lower. If you don't play online games very much or the online games you play are not very sensitive to delays, of course, the lower the tariff, the better ~

I hope I can help you.
