5. EDF network data wiring unit:
The 24-port/48-port Super Category 5 patch panel is mainly used for Gigabit Internet. It is advocated by manufacturers and is now commonly used in local area networks, because the price is not much more expensive than the Category 5 cable, and the current Category 6 patch panel is used. It is generally used in ATM networks and is not recommended for use in company LANs. At present, the common type 5 or type 6 patch panels are common in general local area networks, especially the current type 5 and 6 patch panels can easily provide 155Mbps communication bandwidth, and have the potential to upgrade to gigabit bandwidth, so , Becoming the first choice for horizontal wiring today. And the distribution frame can be divided into: shielded distribution frame and unshielded distribution frame, most local area networks use unshielded distribution frame (UTP-Unshielded Twisted Pair) as the transmission medium for wiring to form a network.
