Cat.7佈線系統與Cat.6有什麼區別？

Cat.7 是一種8芯屏蔽網線，每對都有一個屏蔽層，然後8芯外還有一個屏蔽層，接口與現在的RJ-45不兼容x b a i x i n g c o m。

Cat.7佈線系統和Cat.6佈線系統有很多顯著差別：

1.傳輸帶寬，Cat.7能提供至少600MHz的傳輸帶寬小_百_姓_网。

2.Cat.6提供至少200MHz的綜合衰減對串擾比及整體250MHz的帶寬，Cat.7提供至少500MHz的綜合衰減對串擾比及整體600MHz的帶寬www.xbaixing.com。

3.Cat.6佈線系統既可使用UTP，也可使用STP;Cat.7佈線系統只能使用UTP，且每對線都有一個屏蔽層，四對線合在一起還有一個公共大屏蔽層x b a i x i n g c o m。

4.額外的屏蔽層使得Cat.7的線徑較大来自www.xbaixing.com。

5.Cat.7的連接頭在600MHz時所有的線對提供至少60DB的綜合近端串擾;Cat.5e只要求在100MHz提供43DB;Cat.6在250MHz的數值為46DBx.b.a.i.x.i.n.g.c.o.m。

There are many significant differences between Cat.7 structured cabling system and Cat.6 structured cabling system:

1. Transmission bandwidth, Cat.7 can provide a transmission bandwidth of at least 600MHz.

2. Cat.6 provides a combined attenuation to crosstalk ratio of at least 200MHz and an overall bandwidth of 250MHz, and Cat.7 provides a combined attenuation to crosstalk ratio of at least 500MHz and an overall bandwidth of 600MHz.

3. Cat.6 structured cabling system can use UTP or STP; Cat.7 structured cabling system can only use UTP, and each pair of wires has a shield layer, and the four pairs of wires together have a common large shield layer .

4. The extra shielding layer makes the wire diameter of Cat.7 larger.

5. When the connector of Cat.7 is at 600MHz, all pairs provide at least 60DB of integrated near-end crosstalk; Cat.5e only requires 43DB at 100MHz; and the value of Cat.6 at 250MHz is 46DB.
