| What is integrated wiring? |
|
A: The English expression of integrated wiring is Structured Cabling System (commonly known as Cabling System, referred to as CSC, first proposed by AT&T) or Premises Distribution System (PDS, currently used by the national standard). Integrated wiring is a modular, highly flexible information transmission path within a building or between buildings. It can connect voice equipment, data equipment, switching equipment and various control equipments with information management systems, and also integrates these equipments with external communication networks. It also includes all cables and associated connection components between the connection points of the building's external network or telecommunications line and the application system equipment. Integrated cabling consists of different series and specifications of components, including: transmission media, related connection hardware (such as patch panels, connectors, sockets, plugs, adapters) and electrical protection equipment. These components can be used to build a variety of subsystems, each with their own specific purpose, not only easy to implement, but also smoothly upgrade as demand changes. |
| What is the difference between the Super Category 5 System and the Category 6 System? |
|
A: Super five types of bandwidth is 100MHz; Category 6 line bandwidth is 250MHz; Super Category 5 wire gauge is 24AWG; Category 6 wire gauge is 23AWG; Super Category 5 has no skeleton; Category 6 cable has cross skeleton; |
| What do the English letters that are common in twisted pairs mean? |
|
A: TP----twisted pair UTP----unshielded twisted pair FTP----aluminum foil shielded twisted pair STP----shielded twisted pair LSZH----low smoke and halogen free |
| What is the transmission distance when the Super Five unshielded twisted pair transmits different signals? |
|
A: When the super five unshielded twisted pair is used to transmit data, the channel should not exceed 100 meters, the permanent link should not exceed 90 meters, and 500 meters can be transmitted when transmitting monitoring signals. When transmitting voice signals, it can transmit 3000. Meter. |
| What is the difference between the outdoor network cable and the indoor network cable? |
|
A: The outer sheath of the outdoor network cable is PE (polyethylene), which has the characteristics of anti-corrosion and anti-ultraviolet radiation; the outer sheath of the indoor cable is PVC (polyvinyl chloride), which has good flame retardancy. |
| Is it possible to mix six types of products from different manufacturers? |
|
A: If each component in the system meets the requirements of six types of components and channels, in theory, the wiring system composed of different manufacturers' products should pass six types of tests. |
| Is there a big difference between the Super Category 5 and the Category 6 plug-in modules? Why are the six types of modules so expensive? |
| A: Although there are not much differences between the six categories and the super five modules, the six types of modules have higher transmission performance. For example, in the 100MHZ range, the NEXT value of a Super Category 5 module is 43db, while the value of the six types of modules is 54db. In other words, a super five-type module produces 12 times more noise than six types of modules, and this performance improvement depends on technological improvements, production process improvements, material control, etc., resulting in significant cost increases. |
| Is it necessary to use the manufacturer's six types of jumpers to ensure system performance? |
|
A: The TIA standard has specifications for six types of jumpers and connectors, as long as the product can pass the six types of components and channel standards. The whole system should be able to reach six types of standards, and many manufacturers will specially produce matching cable connectors and jumpers in order to improve the performance margin of the system, so as to greatly improve the transmission performance margin of the system. |
