1. Delay deviation (Skew):The difference in the length of different line pairs in the same cable leads to a difference in the time it takes for the signal to reach the end point in different line pairs in the cable, and the maximum difference is the delay deviation.2. Near-end Crosstalk (Next):In a string loop, the crosstalk received at the same end of the signal source in the main string loop is called nea

1, the production of network cable, the first is to prepare materials, tools, etc., we need materials, tools have a suitable length of twisted pair, a number of RJ45 crystal Head, a twisted pair of wire crimping pliers, twisted pair tester;
2, twisted-pair connection method has two kinds: normal connection and cross connection, the normal connection uses is the international Eia/tia 568B Standard, but the cross connection uses is the inte
I believe everyone is not satisfied with the charge speed of their mobile phone, always hope to make time shorter, charging more quickly. Recently, a project named Doubbletime appeared on the Kickstarter. It is a USB cable for a smartphone device, capable of filling the phone with electricity half the time with a regular USB cable.

Terrible! Hackers can also steal your data by disconnecting the network cable.
Once a computer is infected with viruses or Trojans, most people first think of "disconnecting the network cable first" to avoid the theft of confidential data through the Internet channel. However, according to research by security experts, even if the network cable is disconnected
