The network cable tester can be used to test the five and six types of crystal heads. The network cable tester is usually used to test whether the connection of the crystal head connected to the two ends of a network cable is smooth, which can help determine whether the network cable is in good co

　The insulation resistance of single-mode 12-core optical cable is a key parameter, which directly affects the electrical performance and safety of the optical cable line. Generally speaking, the insulation resistance of optical cable laying is not less than 2000MΩ/km (test voltage 500V, DC). This

　Fiber pigtail and fiber patch cords play different roles in fiber optic communication systems, and there are obvious differences between them. Here is a detailed comparison of the two:　　I. Definition and purpose　　fiber pigtail　　Definition: Fiber optic pigtail, also known as fiber optic trunk line

　SC jumper refers to a cable assembly that is equipped with SC connectors at both ends and composed of optical fibers in the middle for connecting different optical devices. Among them, "SC" represents its connector type and is Subscriber.Connector (user connector or standard connector) abbreviatio

　The crystal head of the super six network cable generally cannot be plugged into the ordinary jack. This is mainly because the super six network cable has higher transmission performance and specification requirements than the ordinary network cable.　　First of all, the bandwidth of the Super 6 net

　The shielded wire of the cable is a specially designed transmission wire, which is characterized by the use of a metal mesh braid (usually made of red copper or tinned copper) to wrap the signal wire. The following is a detailed explanation of the shielded wire:　　First, the definition of shielded

　Oxygen-free copper and pure copper in network cables each have their own characteristics and advantages. Which one is better depends on the usage scenario and needs. Here is a detailed comparison of the two:　　Material purity and properties　　Oxygen-free copper mesh cable　　Made of high-purity oxygen

　Super 6 network cables are usually recommended to be equipped with a Super 6 (CAT6A) crystal head to ensure optimum compatibility and performance. The following is a detailed analysis of the matching of Super 6 network cables with crystal heads:　　First, the characteristics of super 6 network cable

　The differences between Category 6 and Category 7 network cables are mainly reflected in the following aspects:　　Transmission performance　　Transfer rate:　　Category 6 cable (CAT6) supports transfer rates up to 1Gbps and is suitable for Gigabit Ethernet.　　Class 7 cable (CAT7) supports a transmission

　To determine whether the network cable is flame retardant, it can be tested by the following methods:　　Appearance and logo inspection　　Check the outer skin logo: Genuine flame retardant network cables are usually clearly marked with their category and flame retardant grade on the outer skin, such
