• How to Choose a Network Cable

    The network cable actually has a great influence on the network speed. No matter how good your switch or router is and how high the broadband speed is, if the quality of the network cable is not good enough, the entire network will be greatly reduced. At present, the most commonly used network cables in the market are Cat.5e and Cat.6 network cables. Cat.5 network cable has a maximum transmission rate of 100Mbps, which only supports 100M networks, and is now used less. Cat.5e network cable is a transition product from Cat.5 to Cat.6, with stronger anti-interference performance, lower attenuation and higher cost performance during transmission. Cat.5e network cable can be used in Gigabit Ethernet, can stably support 100Mbps transmission rate, and can negotiate up to Gigabit (1000Mbps) rate. Cat.6 network cable can stably support Gigabit networks, and its transmission rate is much higher than Cat.5 and Cat.5e network cables, up to 1Gbps, and can stably support 1000Mbps transmission, and can be used in a network environment requiring a transmission rate higher than 1Gbps. The copper diameter of the Cat.6 network cable is thicker, and the cross-insulating skeleton is added, and the near-end crosstalk and return loss of the network cable are lower. How to choose a network cable?  ①Copper conductor of network cable The conductor diameter of the Cat.5e network cable is 0.511mm, and the conductor diameter of the Cat.6 network cable is 0.574mm. The thicker the copper conductor of the network cable, the smaller the resistance, the better …

    How to Choose an HDMI Cable(Part I)

    HDMI interface version To choose an HDMI cable, first look at the version number of the HDMI interface. The HDMI interface version is different, the bandwidth and supported technology are also different, the high version can be compatible with the low version, so it is best to match the HDMI interface when selecting the HDMI cable, at least not lower than the interface version. If it is lower than the interface version, high-definition images cannot be transmitted. On the contrary, if it is higher than the interface version, although it can be used, you will spend more money. HDMI cable connector The connectors of the HDMI cable are generally gold-plated and non-gold-plated. The gold-plated connectors will have better corrosion resistance, conductivity and high temperature resistance. So normally, cables with gold-plated connectors will be better. Many gold-plated connectors on the market use 24K gold-plated. The brightness is relatively high and it is easy to distinguish. But it’s not that it’s bad if it’s not gold-plated, because the PIN inside the HDMI connector will ultimately work during use. This is the main connection point. This PIN is mainly made of tin bronze. At the time of production, the PIN is first plated with nickel and then gold. Therefore, if the HDMI cable with good workmanship, carefully look at the PIN, you will find that there are three layers. Thickness of HDMI cable Some HDMI cables are thick and some are thin, how to choose? Normally, for the same brand, the thicker the …
