六類網線中的白色十字骨架有什麼作用

六類網線內部基本含有個白色十字骨架、4對絞線和一條抗拉線。那麼，這個白色十字骨架有什麼作用呢?

六類網線內部的十字骨架主要是用來保持4對線芯的先對位置，有利於減少線對間的串擾問題，同時可以提高電纜的平衡特性。

此外，在布線過程中，由於六類網線導體大小比超五類網線粗，且內部有十字骨架，外徑也比超五類網線要粗，所以布線技術上會有一定的難度。一般來說內徑20mm的線管以放2根六類線為主，防止線纜相互纏繞。

六類網線主要是傳輸千兆網絡，要搭配千兆交換機，千兆路由器才能使用，如果搭配百兆交換機和百兆路由器只能傳輸百兆網絡。

What is the role of the white cross skeleton in the six types of cable?

The cross skeleton inside the six types of cable is mainly used to maintain the position of the pair of cores, which is beneficial to reduce the crosstalk between the pairs and improve the balance characteristics of the cable.

In addition, in the wiring process, since the size of the six types of network cable conductors is thicker than the super five types of network cables, and the inside has a cross skeleton, the outer diameter is also thicker than the super five types of network cables, so the wiring technology will have certain difficulty. Generally, the inner tube with an inner diameter of 20 mm is mainly composed of two six-type wires to prevent the cables from being entangled with each other.

The six types of network cables are mainly for transmitting Gigabit networks. To be used with Gigabit switches, Gigabit routers can be used. If they are combined with 100Mb switches and 100Mb routers, only 100Mb networks can be transmitted.
