Video, commonly known as cable or CATV, is one of today's most demanding applications. It uses signal frequencies from 54MHz to over 600MHz. Broadband video is typically used on home networks using coaxial cable (RG-59 and RG-6). The most demanding application today is video (ie cable TV or CATV), which carries signals from 54MHz to 600MHz, so there are quite strict requirements for the broadband supported by twisted pair.
After the TIA/EIA announced the six categories of standards in 2002, the transmission performance of the Category 6 cabling system can reach 250 MHz, which is at least doubled compared to the Super Category 5/Category bandwidth (100 MHz). Higher signal-to-noise ratio means Six types of systems are less susceptible to slowing down the network by transceivers and other environmental factors, providing optimal data throughput and reduced bit error rates. It also offers possibilities for video applications. In short, the results show that the Super Category 5 system can simultaneously transmit 38 channels of video at a distance of 100 meters, and the Category 6 system can simultaneously transmit 54 channels of video at a distance of 100 meters.
One of the great benefits of running video on a twisted pair is that you can use multiple pairs of 4 pairs of lines to simultaneously transmit multiple channels, or you can use two pairs for two-way video transmission and the ability to simultaneously transmit video and cable over a single cable. The telephone signal, combined with the data application, truly achieves multi-network integration. This solution greatly saves the cost of the video six-category cabling system in the intelligent building, and provides higher stability for the transmission of security monitoring systems and video conferencing systems, and has become a new direction for intelligent building integration applications.
Category 6 cabling system combined with building automation
When the Category 6 cabling system was first applied to smart buildings in China, it was only used as a transmission channel for voice and data. At that time, the six types of cabling systems such as Building Automation System (BAS) and Security System (SA) were still independent, so it can be said that The application significance of the six-category wiring system has not been truly fully realized.
However, with the increasing demand for intelligent building integration in China, the six-category wiring system as an intelligent building "information superhighway" not only undertakes the functions of voice and data transmission, but also is required to be able to work with building automation systems (BAS) and security systems. (SA) and other closer combinations. This converged solution has the following advantages:
Building automation systems and Category 6 cabling systems are routed simultaneously, saving time and labor. Combined with the six types of wiring system, it greatly facilitates the wiring management and maintenance of the building automation system. The two transmission media are combined for easy procurement, design and acceptance.
For example, the Belden IBDN Control Plus cable provides a stronger tensile force, more length margin and greater current capacity in addition to a dedicated 22AWG cable for control applications. The conductor is insulated with FEP, in many inferior environments. It offers more protection and also provides over 5 performances for web applications.
With the continuous emergence of new standards, new technologies and new products, and the increasing requirements for the integration of intelligent buildings in China, it is believed that the above-mentioned points will be more and more reflected in the six types of wiring system projects of intelligent buildings in various places. Make domestic applications more international.
