Rj45-rj45 six types of jumpers detailed introduction

　　RJ45-RJ45 type 6 jumper is a commonly used cable in the process of network debugging, maintenance and upgrade. The following is a detailed introduction to RJ45-RJ45 type 6 jumper:

　　I. Definition and Classification

　　Definition: RJ45-RJ45 type 6 jumper belongs to a type of 6 twisted pair, which is a network jumper without a shielding layer, mainly used to achieve high-speed and stable data tranSMission between devices.

　　Classification: According to the different specifications such as length and color, RJ45-RJ45 six types of jumpers can be divided into various types to meet the connection requirements of different devices and scenarios. At the same time, the six types of jumpers are not limited to RJ45 to RJ45 interface types, but also include RJ45 to BNC, RJ45 to DB9 and other types.

　　II. Structure and characteristics

　　Structure: RJ45-RJ45 six types of jumpers are usually composed of multi-strand core wire structure, which has the characteristics of good softness. The outer layer of the cable is usually made of PE or PVC and other materials, which have insulation and flame retardant properties. The crystal head part is made of gold-plated sheet to ensure good contact and signal transmission performance.

　　Features:

　　Fast transmission speed: Six types of jumpers support Gigabit Ethernet transmission to meet the needs of high-speed data transmission.

　　Strong anti-interference ability: Special design and materials are used to effectively reduce electromagnetic interference and signal attenuation.

　　Easy construction and maintenance: The length of the jumper can be customized according to actual needs, making it convenient for wiring and management.

　　III. Performance indicators and testing

　　The performance indicators of RJ45-RJ45 six types of jumpers include attenuation, near-end crosstalk, far-end crosstalk, attenuation to crosstalk ratio, sum-up near-end crosstalk/sum-up far-end crosstalk, return loss, transmission delay, delay difference, bandwidth, etc. These performance indicators ensure the stability and reliability of the jumper during high-speed data transmission. At the same time, the jumper needs to undergo strict testing and inspection during the production process to ensure that its quality meets relevant standards and requirements.

　　IV. Application scenarios

　　RJ45-RJ45 six types of jumpers are widely used in various network devices and scenarios, such as switches, routers, servers, computers, etc. In data centers, offices, home networks and other places, six types of jumpers play an important role.

　　V. Selection and Precautions

　　When purchasing RJ45-RJ45 six types of jumpers, it is necessary to pay attention to whether the length, color, specifications, etc. of the jumpers meet the actual needs. At the same time, choose brands and models with reliable quality and stable performance.

　　Precautions: When using RJ45-RJ45 six types of jumpers, care should be taken to avoid improper operations such as pulling and excessive bending, so as not to affect the performance and life of the jumper. At the same time, ensure that the connection between the jumper and the device interface is firm and reliable to avoid loose or poor contact.

　　In summary, the RJ45-RJ45 six-type jumper is a network connection cable with excellent performance, moderate cost, easy construction and maintenance, suitable for a variety of network and device connection scenarios. During the purchase and use process, relevant matters need to be paid attention to to ensure its performance and stability.
