Chinese-English Translation:

六类和七类布线系统有很多显著的差别,最明显的就是带宽。六类信道提供了至少200MHZ的综合衰减对串扰比及整体250MHZ的带宽。七类系统可以提供至少500MHZ的综合衰减对串扰比和600MHZ的整体带宽。

There are many significant differences between Class 6 and class 7 cabling systems, the most obvious of which is bandwidth. The six channels provide a comprehensive attenuation to crosstalk ratio of at least 200MHz and an overall bandwidth of 250MHz. Seven types of systems can provide at least 500MHz comprehensive attenuation to crosstalk ratio and 600MHz overall bandwidth.

There are many significant differences between Class 6 and class 7 cabling systems, the most obvious of which is bandwidth. The six channels provide a comprehensive attenuation to crosstalk ratio of at least 200MHz and an overall bandwidth of 250MHz. Seven types of systems can provide at least 500MHz comprehensive attenuation to crosstalk ratio and 600MHz overall bandwidth.

六类网线传输频率为 1MHz~250MHz,六类布线系统在 200MHz 时综合衰减串扰比(PS-ACR)应该有较大的余量,它提供 2 倍于五类的带宽,五类线为 100M、超五类为 155M、六类为 200M。六类布线的传输性能适用于传输速率高于 1Gbps 的应用。

The transmission frequency of category 6 network cable is 1MHz ~ 250MHz. The PS-ACR of category 6 cabling system should have a larger margin at 200MHz. It provides two times of the bandwidth of category 5, 100m for category 5, 155m for category 5 and 200m for Category 6. The transmission performance of type 6 cabling is suitable for applications with transmission rate higher than 1Gbps.

超六类网线也叫 6A,能支持万兆上网,目前最大能达到 500MHZ,是六类网线的两倍,目前 6A 分为非屏蔽跟屏蔽两种,非屏蔽从外观上看跟六类网线差不多,细节上看就比较明显了,6A 的绞距更密些,而且导体也比较粗,最重要的改变是在 PVC 外被上的改变,增加塑料棒或者 PVC 外被做成锯齿状来改善外开扰测试指标。

Super class 6 cable, also known as 6a, can support 10 Gigabit Internet access. At present, the maximum capacity can reach 500 MHz, which is twice that of class 6 cable. At present, 6a is divided into two types: unshielded and shielded. Unshielded cable is similar to class 6 cable in appearance, but it is more obvious in details. The twist distance of 6a is denser, and the conductor is thicker. The most important change is in PVC To improve the performance of external disturbance test, add plastic bar or PVC coating to make serrated.

而屏蔽类超六类网线,这种是屏蔽则采用对对屏蔽的结构,跟传统的屏蔽有很大的区别,这种对对屏蔽可以防止没对线芯对其他线芯的干扰,既能起到防止外界的干扰还可以增强自己的信号衰减值的最小化,成本较高。

The shielding super class 6 network cable adopts the structure of pair shielding, which is very different from the traditional shielding. This pair shielding can prevent the interference of the wire core to other wire cores, which can not only prevent external interference, but also enhance the minimization of its own signal attenuation value, with high cost.

七类网线不再是一种非屏蔽双绞线,而是一种屏蔽网线,而六类存在 UTP 非屏蔽结构和 FTP 屏蔽结构,这是结构上主要的不同之处。

Class 7 network cable is no longer a kind of unshielded twisted pair, but a kind of shielded network cable, while class 6 network cable has UTP unshielded structure and FTP shielded structure, which is the main difference in structure.

在七类线缆中,每一对线都有一个屏蔽层,四对线合在一起还有一个公共大屏蔽层。从物理结构上来看,额外的屏蔽层使得七类线有一个较大的线径。从传输性能上来看,七类网线可提供至少 500MHZ 的综合衰减对串扰比和 600MHZ 的整体带宽,是六类线和超六类线的 2 倍以上,传输速率可达 10Gbps。

In the seven types of cables, each pair of wires has a shielding layer, and four pairs of wires together have a common large shielding layer. From the point of view of physical structure, the additional shielding layer makes the seven kinds of wires have a larger diameter. In terms of transmission performance, class 7 network cable can provide at least 500MHz comprehensive attenuation to crosstalk ratio and 600MHz overall bandwidth, which is more than twice of class 6 and super class 6 network cable, and the transmission rate can reach 10Gbps.

超七类网线跟七类网线最大的区别在于,七类网线带宽 600MHZ,超七类网线的带款是 1000MHZ,这是两个网线性能上最根本的区别。

The biggest difference between category 7 cable and category 7 cable is that the bandwidth of category 7 cable is 600MHz, while the bandwidth of category 7 cable is 1000MHz, which is the most fundamental difference in the performance of the two cables.

七类网线的组成

Composition of seven kinds of network cable

采用 4 对芯径 23AWG 单股优质无氧铜为导体(铜导体外具有 FMPE 材料绝缘),线对与缆线整体铝箔高效双屏蔽结构,十字架隔离,传输频率也扩展至 600MHz。七类网线是一种 8 芯屏蔽线,每对都有一个屏蔽层(一般为金属箔屏蔽 Foil Shield),然后 8 根芯外还有一个屏蔽层(一般为金属编织丝网屏蔽 Braided Shield),接口与现在的 RJ-45 相同。

Four pairs of 23AWG single strand high-quality oxygen free copper conductors (the copper conductor is insulated with FMPE material) are adopted. The wire pair and cable are integrated with aluminum foil high-efficiency double shielding structure, with cross isolation, and the transmission frequency is extended to 600MHz. Class 7 cable is a kind of 8-core shielded wire, each pair has a shielding layer (generally foil shield), and then there is a shielding layer (generally braided screen shield) outside the 8 cores. The interface is the same as that of RJ-45.

七类网线的适用范围:

The scope of application of the seven types of network cable is as follows:

广泛应用于室内水平布线、屏蔽机房及保密网布线

It is widely used in indoor horizontal wiring, shielded computer room and secure network wiring

七类屏蔽跳线

Class 7 shielded jumper

采用多芯裸铜软线为导体,跳线传输性能表现突出,适用于 10/100/1000/10GBASE-TX 以太网数据传输;缆线整体铝箔高效屏蔽,应用于屏蔽布线中,起到抗干扰作用。

The multi-core bare copper flexible wire is used as the conductor, and the jumper transmission performance is outstanding, which is suitable for 10 / 100 / 1000 / 10gbase-tx Ethernet data transmission; the overall aluminum foil of the cable is highly efficient shielding, which is used in shielding wiring to play an anti-interference role.

七类网线和六类网线的区别是什么

What’s the difference between type 7 network cable and type 6 network cable

1、二者的宽带上面有一些区别。有一个词叫综合衰减对串扰比,这两类网线都会提供这样的东西,六类网线提供的不低于 200 兆赫兹,而七类网线可以提供不少于 500 兆赫兹,前者可以提供不少于 250 兆赫兹的带宽,而后者至少可以提供 600 兆赫兹的带宽。

1. There are some differences in broadband between the two. There is a word called comprehensive attenuation to crosstalk ratio. These two types of network cables will provide such things. The six types of network cables can provide no less than 200 MHz, while the seven types of network cables can provide no less than 500 MHz. The former can provide no less than 250 MHz bandwidth, and the latter can provide at least 600 MHz bandwidth.

2、七类网线的布线性能提高得比六类网线显著,因此它的介质的传输能力与衰减水平几乎等同于光纤性能。

2. The routing performance of type 7 network cable is significantly better than that of type 6 network cable, so the transmission capacity and attenuation level of its medium are almost equal to that of optical fiber.

3、二者在结构上也存在着差别。六类网线可以使用非屏蔽双绞线,也可以使用屏蔽双绞线,但是七类网线只能使用屏蔽双绞线。七类网线中有一个东西叫屏蔽层,它每两根线组成一对,然后可以建造出一个屏蔽层,四个屏蔽层组合在一起就是一个公共的大屏蔽层。

3. There are also structural differences between them. Category 6 network cable can use unshielded twisted pair or shielded twisted pair, but category 7 network cable can only use shielded twisted pair. One of the seven types of network cables is called shielding layer. Each two wires form a pair, and then a shielding layer can be built. Four shielding layers are combined to form a common large shielding layer.

4、它们在连接硬件的能力上也有很大的差别。七类网线要求它的连接头在达到 600 兆赫兹的时候需要提供至少 60DB 的综合近端串扰,六类网线在使用的时候,网速不超过一百兆。

4. They also differ greatly in their ability to connect hardware. Class 7 cable requires its connector to provide at least 60dB of comprehensive near end crosstalk when it reaches 600 MHz, while class 6 cable does not exceed 100 MHz when it is used.
