2022-10-10 How coaxial cables work? Coaxial cables have concentric layers of electrical conductors and insulating material. This construction ensures signals are enclosed within the cable and prevents electrical noise from interfering with the signal. UCOAX Micro Coaxial Cables AWG 36-46 Cable Assembly Custom Made Your Cable The center conductor layer is a thin conducting wire, either solid or braided copper. A dielectric layer, made up of an insulating material with very well-defined electrical characteristics, surrounds the wire. A shield layer then surrounds the dielectric layer with metal foil or braided copper mesh. The whole assembly is wrapped in an insulating jacket. The outer metal shield layer of the coaxial cable is typically grounded in the connectors at both ends to shield the signals and as a place for stray interference signals to dissipate. A key to coaxial cable design is a tight control of ca

2022-09-23 Micro Coaxial Cable What is Coaxial Cable? Cables that have a simple structure with a conductor covered with a jacket are called Discrete Cables. Whereas cables with a multi-layered structure with a center conductor covered with an insulator layer along with an outer conductor and jacket are called Coaxial Cables. The coaxial cable outer conductor plays the role of electromagnetic shield so the electrical signal transmitted through the center conductor is less susceptible to electromagnetic waves (electromagnetic noise) from the outside.

2022-09-20 Coaxial Cable and It's Application What is Coaxial Cable? Where is it used? Coaxial Cable is an energy current carrying product that is covered with insulating material and has one or more metallic conductors in it, which is used in the fields of electricity and electronics. Coaxial cable can also be defined as a type of copper cable used in environmental conditions where electrical noise is intense. The use of copper is preferred in most networks, since copper`s low resistance to electric current allows signals to be carried farther. Coaxial cables have a high capacitance value, Television, telephone networks, local area networks and CATV (Community Antenna Television) are among the application areas of coaxial cables. Although these cables are used in long distance telephone networks, they have been replaced by fiber optic cables and satellite systems in this field. Today, coaxial cables are used in television and camera systems and are used in the transmission of high frequency signals of radio, television and telephones. Coaxial cables are also very efficient at carrying high frequency analog signals. Because of their features, coaxial cables are used for data transmission in residential, commercial

2022-09-20 High-Frequency Transmission Line Signal Analysis Fundamentals of high-frequency transmission line signal analysis What is a transmission line? Transmission Line Theory Sources: In signal integrity and power integrity, engineers must understand the theoretical basis of transmission lines, and simple transmission line theory is given here. If the signal transmitted on the transmission line is a low-frequency signal, assuming 1KHz, then the wavelength of the signal is 300 kilometers (assuming that the signal speed is the speed of light), even if the length of the transmission line is 1 meter long, it is still very short relative to the signal, and the transmission line can be regarded as a short circuit for the signal, and the influence of the transmission line on the signal is very small. However, for high-speed signals, assuming that the signal frequency is increased by 300MHz, the signal wavelength is reduced to 1 meter, at this time, the 1 meter transmission line and the wavelength of the signal can be completely compared, there will be a fluctuation effect on the transmission line, and the voltage and current at different points on the transmission line will be different. In this case, we cannot ignore the impact of the transmission line on the signal. The transmission line is a long line relative to the signal, we have to use the theory of long-term transmission to solve the problem, especially at high frequencies, the transmission line theory cannot be ignored.

2022-09-19 Physical Foaming Cable Wire Extruding Machine Physically foamed FEP contains a uniformly dispersed nucleating agent for foaming during gas injection extrusion. During processing, as the gas expands, a void begins to form, and the nucleating agent added to the physically foamed FEP will provide space for the formation of the void, and then the insulation or profile extruded into the forming of a foamed FEP structure. After the physical foaming technology is adopted for FEP, if the foaming degree is increased from 0% solid to 50%, the material can be saved by about 65%, while the transmission rate ratio (relative to the transmission rate of the signal in the vacuum) can be raised from 66% to 81%, and the material savings per kilometer are very considerable. Reducing costs and waste, protecting the environment, and improving product performance are the missions of UCOAX. To meet the requirements of the high-performance cable manufacturing described earlier, whether it is the insulation material itself or the wire extrusion process is a new challenge, first of all, in the extrusion and melting process of the foam material, the nitrogen is required to be integrated into the insulating material as fine as possible, the problem in this field is to provide the foaming degree and stability of the material as much as possible to meet the very small foam pore size and meet sufficient mechanical strength, secondly, The second area of the problem is how to ensure the best

2022-09-09 HDMI 2.0 specs What you should know about HDMI Cables & HDMI 2.0? Is there an HDMI 2.0 cable? The simple answer is no. As defined by HDMI 2.0 specs, there are four main HDMI cable types: Standard Speed HDMI Cable Standard Speed HDMI Cable with Ethernet High Speed HDMI Cable High Speed HDMI Cable with Ethernet In addition to these main HDMI cable types, C2G Performance Series HDMI Cables are defined within the HDMI 2.0 specs. Please check back soon to learn more about our Performance Series HDMI Cables. Does cable length impact available bandwidth? The testing spec outlined within the HDMI 2.0 specs allow cables to be placed within these different categories; however, that categorization does not necessarily limit what features a cable is able to support. The bandwidth and length of an HDMI cable are inversely proportional to one another, meaning that a shorter length cable has a higher available bandwidth. Available bandwidth is one of the cable types that call out Ethernet support. At longer distances, an active HDMI cable or extension device may be required to support HDMI 2.0 features, these may fall into a few different categories:

2022-09-08 What's the maximum current that the copper wire can withstand What's the maximum current that the copper wire diameter can withstand The current data line, in addition to the high frequency parameters, the most basic electrical parameters are resistance, voltage drop, voltage, etc., but the most asked by the guests is the corresponding data line can withstand how much current, with how much conductor (AWG) can meet the customer's test requirements, to prevent overheating caused by too much current, and cause accidents, today we talk about the copper wire diameter can withstand the maximum current. Before studying the current need to understand the resistance: the part of the current that acts as an obstacle and causes energy consumption through the current, we call it resistance, and the resistance is often expressed in R, in units of Ω, KΩ, MΩ. For the case of constant cross-sectional area, the approximate calculation formula of the conductor resistance: R = ρ× L/SL=length (m), S = wire bearing surface (m㎡), L: wire length; S: Conductor cross-sectional area; ρ: conductor resistivity, in Ω meters; Wire resistance is determined by wire material, cross-sectional area and length. The impedance of a wire is proportional to its length and inversely proportional to its wire diameter, and the focus of resistance in physics is that the carrying current of a conductor (resistor) is independent of its length and is related to cross-section S; If the cross-sectional area of the two conductors (resistors) is the same and the current flowing is the same, the larger the cross-sectional area circumference of B, the higher the temperature rise of the conductor; The better the packaging of the conductor (resistance), the smaller the comprehensive heat dissipation coefficient Kt and the higher the temper
