://bianceng.cn (computer science) Also, an ideal equilibrium transmission system does not exist. The balance characteristics of UTP cables are not only determined by the quality of the parts themselves (such as twisted pair), but are affected by the surrounding environment. Because of the metal around UTP, hidden "ground", pulling in the construction, bending and so on will damage its balance characteristics, thereby reducing EMC performance. In fact, the cable we install is usually put into a

aluminum foil on all core wires. Aluminum Foil protects the fragile twisted pair core wires and creates a balance environment for UTP cables. This means that the solution for the FTP cable-based shielded cabling system is independent of the environment, that is, it is not related to the environment. FTP is a perfect combination of UTP's Balance Characteristics, construction flexibility, and STP shielding e

Capacitor type and usage, basic knowledge Capacitor is one of the most widely used electronic components in electronic equipment. It is widely used in the fields of direct separation, coupling, bypass, filtering, tuning loop, energy conversion, and control circuit. Capacitance frequency characteristics: As the frequency increases, the capacitance of a general capacitor decreases. Capacitance Model naming method: (based on GB2470-81) Part 1: use letters to indicate the product name c Part 2: Us

Recently, some netizens have bought their iphone6s on the back of the painting to the internet has caused a lot of users resonance. Think the original iphone6s just on line because the problem of easy to bend the material replaced by a new 7000 series of aluminum, although this makes the hardness greatly increased but there is a fatal problem is the oxidation of serious. Although it may not be visible when you buy it, it is now estimated that many

. What materials are used for the optical fiber sheath? Answer: The cable sheath or protection layer is usually composed of polyethylene (PE) and polyvinyl chloride (PVC) materials. Its function is to protect the cable core from external influences. 25. List the special optical cables used in power systems. A: There are three types of special optical cables: The OPGW is placed in the power line of the aluminum-twisted steel ladle structure. The App

As an Apple family home-level product, MacBook has always been using fashionable and beautiful engineering plastic casings, and has always followed the integrated graphics card design. In addition to upgrading the conventional hardware configuration, the latest MacBook a1278 adopts the full aluminum alloy one-time molding technology design for the first time, and adds support for NVIDIA chips ...... With its superb craftsmanship and cutting-edge desig

If you remove the bottom of the coffee maker, you will find: Internal view at the bottom of the coffee maker The right concave part of the image is the bottom of the bucket, and the orange catheter in the middle is the hot water pipe (connected to the Black catheter shown abo

1. The cabling standard classifies shielded twisted pair wires. Compared with the version 2000 standard, the current debate on the shielded wiring system is basically absent, and the discussion of engineering applications and methods is underway. With shieldingTwisted Pair wiresIn the new standard, four representative shielded twisted pair structure are defined, which makes the shielded twisted pair no longer a general concept, and began to enter the rational application stage of shielding perfo

Overview of shielded twisted pair wires Electromagnetic Waves with frequencies greater than 5 MHz can only pass through 38 μm thick aluminum foil. If the thickness of the shielding layer exceeds 38 μm, for exampleFTPThe cable is shielded with aluminum foil with a thickness of 25 μm, so that the frequency of electromagnetic interference that can enter the cable through the screen is below 5 MHz, the dual-twi

A lot of people will see in the motherboard parameters about the capacitance, which is the main board of solid-state capacitor price is usually higher, the solid-state capacitor and the liquid capacitor what is the difference? Solid capacitors are all known as solid aluminum electrolytic capacitors. It differs from ordinary capacitance (that is, liquid aluminum electrolytic capacitors) The biggest differen

The purpose of twisted pair wire shielding is to cut off the path of Space electromagnetic radiation to the core line of the twisted pair wire, or to reduce the intensity of Space electromagnetic radiation. The traditional shielded twisted pair wires (such as F/UTP and SF/UTP) are used to add multiple shielding layers (such as aluminum foil shielding layer and copper mesh braided shielding layer) to the outer layer of the four core wires ), if one lay

simple, look at the Fan Power Supply interface on the line-4 pin table support. (Unless it is a false four-wire, the two boxes are all four-wire, but it is not temperature controlled, pay attention to the distinction; then it is the motherboard of the gigabyte am3 interface, 760, 780, 770,880 and so on all am3 interface gigabyte motherboard, even if the fan is 3 P, still support speed control. It has a temperature control circuit, through the software ET-6 can be adjusted, installed on the fan

after the degree of flexibility will increase. Need to explain is that the color of the PCB can not represent quality, color is only a layer of antirust paint, the main protective effect, what color. The black or blue boards are now popular, but many of the real high-end motherboards are still dark green in the past. Method 3--look at the materials of parts One of the most important types of materials that affect the quality of the motherboard is capacitance and connectors. Capacitance in t

notebooks, which laid the foundation for the MacBook and MacBook Pro, and became a hallmark of the "rationalism" period. The same year also released the first generation of the ipod, its design, is "Titanium book" style continues to sublimate, the same metal shell, more concise lines, more heavy appearance, the plane with rounded corners of the perfect combination. Its appearance shows that Apple's design style has completed a successful transformation process, "rationalism" has slow
