When it comes to HD mini sas high-speed copper cable wiring system, friends engaged in wiring related industries know more about this. So, what is HD mini sas high-speed copper cable wiring system? How do we choose HD mini sas high-speed copper cable wiring system? Let's find out.

HD mini sas high-speed copper cable wiring system refers to the preparation and layout of communication lines of various systems in each building (or multiple buildings), including the network system, telephone system, monitoring system, power supply system and lighting system, in accordance with a standard, unified and simple structured method. Therefore, this type of high-speed copper cabling system is the standard general purpose information transmission system.

First, bandwidth and transmission rate

When it comes to wiring a project with new high-speed copper cables, two concepts need to be distinguished: bandwidth (in MHz) and data transfer rate (in Mbit/s). If you can't distinguish between these two concepts, it's hard to make the right choice. For its definition and specific meaning, please refer to the relevant technical terms. Here we should point out the relationship between the two. This relationship is related to coding methods and other techniques, but is not necessarily a one-to-one relationship. For example, atm155, where 155 indicates the data transmission rate, that is, 155 Mbit /s, but the actual bandwidth is only 80MHz. Another example is 1000mbit/s Gigabit Ethernet. Due to the four pairs of full-duplex working mode, the transmission bandwidth requirement is only 100MHz. Data transfer rates are widely used in computer network operations, and the related high-speed copper cable installation industry uses the same type of bandwidth, so don't confuse the two.

Second, the new HD mini sas high-speed copper cable system

① Enhanced CAT5 HD mini sas high-speed copper cable system: It is a new high-speed copper cable wiring engineering system specially modified after improving some performance of existing 5 UPT twisted pair cables. Many performance parameters such as near-end crosstalk (next) and attenuated crosstalk ratio (ACR) have been improved, but their transmission bandwidth is still 100MHz.

② Class 6 copper cable system (CAT6) : the new level of copper cable system. In addition to greatly improving various performance parameters, its bandwidth will be expanded to 200MHz or higher.

③ Class 7 copper cable system: Class 7 copper cable system is the cable standard proposed by Europe. It has a planned bandwidth of 600MHz, but the architecture of its connection modules is completely incompatible with the current RJ-45. It's a masking system.

When HD mini sas high-speed copper cable system first entered our country, it gave us a mysterious feeling. It seems that once the building has a wiring system, it will immediately become a smart building, and all weak current systems can use this wiring system. In fact, theoretically speaking, the integrated wiring system will unify the transmission medium of the weak current system in the building into a high-performance transmission medium, which is easy to manage, maintain and expand. But in fact, at present, we cannot and need not do this at home.
