connected directly with How to make Gigabit cable The form of Gigabit 5 or Super 5 twisted-pair lines is the same as that of the hundred-gigabit cable, which is also divided into two kinds: straight and cross. Straight line cable and we usually use no difference, are one by one corresponding. But the traditional hundred gigabit network only uses 4 cables to tr

Influence of internal resistance of USB data cable on charging current Mobile phone and tablet Charger interface for USB interface, the use of the adapter through the power of the USB cable and ground to form a loop to charge the phone, if the quality of the data line, the resistance of the line is large, charging current in the data line pressure drop will become larger. The input voltage on the power man

It is because the official Ubuntu system needs to set something for the first time, similar to the initial startup of Windows, if not set up, even the operation account is not (root), so even SSH can not use the eggs. So you need to choose a non-official, s

Its matching resistance is 120 euro. 2, 10BASE5: Coarse coaxial cable, the use of plug-in joints, baseband signal, the maximum supp

To build a new broadband community, we have many options, including the Ethernet access scheme, ADSL access scheme, Cable Modem and hfc-network scheme, and optical fiber access scheme. How should we choose these access solutions? Different solutions vary in application scenarios. Let's take a look at the features of several access solutions. High-speed Ethernet solution In the broadband access technology, Ethernet has become the most widely used loca

This article introduces the optical fiber cabling system. Many people may not know about the optical fiber cabling system yet. I believe you will have a rough understanding of the optical fiber cabling system after reading this article, I hope this article will teach you more things. After the optical cable cabling system is installed, You need to test the link transmission characteristics. The main test items are the attenuation characteristics of th

Data center energy saving does not affect network cable cooling At present, the data center's heat dissipation is generally designed to separate hot and cold channels, that is, the cold and hot channel control technology, to isolate the cold and hot channels, to prevent mixed cold and hot air, the cold channel helps the device get the air-conditioning flow, and then the hot air flow is discharged through the hot channel. In this mode, the data center
