For the communication industry, it is often necessary to use copper cables for laying communication lines, and the commonly used equipment material is HD mini sas high-speed copper cable. The reason why this equipment material is used is that it has many advantages. The following will introduce the advantages of HD mini sas high-speed copper cable in detail.

1. Wide frequency band and fast speed

In theory, the HD mini sas high-speed copper cable can reach 3 billion MHz band. Although the high speed copper cable has different loss to different frequency of light, the bandwidth in the lowest loss region can reach 30000GHz. Using advanced coherent optical communication technology, it can arrange 2000 optical carriers for wavelength division multiplexing in the 30000GHz range, accommodating millions of channels. At the same time, high-speed copper cable transmission speed is fast, can provide 10Mbps, 100Mbps, 1000Mbps high-speed bandwidth, two-way data synchronization transmission.

2. Light weight and small size

Because the high-speed copper cable is very thin, the core diameter of single-mode high-speed copper cable is generally 4um~10um, and the outer diameter is only 125um. With waterproof layers, stiffeners, and sheathing, the cable, which consists of 4 to 48 high-speed copper cables, is less than 13mm in diameter, much smaller than the 47mm diameter of a standard copper-shaft cable (see figure below). In addition, the high-speed copper cable is glass fiber, small specific gravity, small diameter, light weight characteristics. One kilometer of bare HDminisas high speed copper cable weighs only 27g. This characteristic of high-speed copper cable makes its laying method convenient and flexible. It can not only be laid directly in the ground, pipeline laying, but also under water and overhead laying.

3. Large communication capacity

In theory, a high-speed copper cable the thickness of a human hair could transmit 100 billion channels simultaneously. Although such a high transmission capacity has not yet been achieved, the simultaneous transmission of 240,000 channels using a single high-speed copper cable has been successfully tested. It is dozens or even thousands of times higher than traditional open line, coaxial cable and microwave. The transmission capacity of a single high-speed copper cable is so large that a single cable can contain dozens or even thousands of high-speed copper cables. If you add wavelength-division multiplexing technology, and use one high-speed copper cable as several or dozens of high-speed copper cables, the ability to communicate is even more amazing.

4. Low loss, long transmission distance

In general, the attenuation per kilometer of high-speed copper cable access is more than an order of magnitude lower than that of today's largest capacity communications coaxial cable. At present, the attenuation of commercial quartz high-speed copper cable has reached below 0.19db/km. High-speed copper cables can relay hundreds of kilometers or more if equipped with appropriate light transmitting and receiving equipment. Ordinary copper wire (data line) transmission distance is only a few hundred meters. Therefore, high - speed copper cable communication is particularly suitable for long - distance main - slave communication.

5. Strong confidentiality and anti-interference ability

HD mini sas high-speed copper cables only transmit light, do not conduct electricity and are not affected by electromagnetic fields. Therefore, it has a strong ability to resist electromagnetic interference and industrial interference. Because of this, HD mini sas high-speed copper cable transmission signal is not easy to be heard, so it has strong security.
