Summary
As the LAN speed increases, the transmission capability of the cabling system will depend on the outstanding performance of all components in the cable and LAN channels.
End-to-End cabling system manufacturers are not manufacturers of individual components) have obvious advantages in terms of end-to-end channel performance. Obviously, in this case, the excellent design of cables, Jacks, and plugs wi

1. Work Summary
Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future
solution is to design the network in order to meet the requirements of network changes and growth to plan accordingly.
1. Investment protection in the future
Under normal operating conditions, the new network should not limit system upgrades during the 15 building renovation cycle. A well-designed cabling system can withstand data traffic that is 10~15 times higher than most LAN transmission rates. This will allow the use of new network technologie

Since the birth of the concept of structured cabling, command signals, control signals, and communication signals have been centrally transmitted through a common
In the digital age, you and I will be able to cross the border of the region without leaving home, and go all over the world of information, relying on the ever-changing data transmission technology. A seemingly illusory, hard-to-touch technical concept is closely related to us. The key lies in the structured cabling network in which we are surrounded.Structured Cabling

Structured Cabling System inlet may have a major impact on the ability of cables to support high-speed data applications (such as fast Ethernet and Gigabit Etherne
When determining the installation and supply of bids for the network, the total investment cost of the network owner is a key factor. BecauseStructured CablingThe system network has a service life of at least 15 years, so the network operation cost and upgrade cost will be equal to or greater than the initial investment amount. After the network is installed, adding, removing, and changing devices connected to the network usually requires a large investment.
