七类线是一种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RJ-45相同。 总屏蔽（一般为金属编织丝网屏蔽）+ 线对屏蔽（一般为金属箔屏蔽） 七类线 S/FTP Cat.7 (HSYVP-7) 最高传输频率 600MHz，超七类线的传输频率为1000MHz。 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 …

Cat 7. Category 7 S/FTP plenum-rated cables helps to meet the demand for the growing number of IP access points, and network security applications exceeding 10 Gigabit Networking (10G) bandwidth over 100m. This cable is also ideal for Future 4K Resolution Video because they deliver superior performance in high bandwidth applications up to 625 ...

AWG是美式线规，简单理解成 标号越大，线径越细，载流能力越低。 对于网线虽然是传输的主要高频信号 (POE的话还有48V的直流电)，跟电阻没有直接关系，但趋肤效应的存在，显然也是相对粗一些好。 此外，大概是知乎上卖网线的比较多，瞎话都成真理了，实际上，CAT7对家装和日常办公都是毫无意义的， 包括需要万兆的情况下。 随着工艺的提升，合格的超五类网线，可以在55米的距离上完整支持10Gpbs/万兆速率，之前这个标准是为超六类线设计的。 对于更高 …

Cat7网线支持高达600MHz的频率带宽，并且还支持10GBASE-T以太网，此外，与Cat6网线和Cat6a网线相比，Cat7网线大大降低了串扰噪声。 Cat5e网线、Cat6网线和Cat6a网线都有RJ45连接器，但Cat7网线的连接器比较特殊，它的连接器类型是GigaGate45（CG45）。

2024年4月26日 · Category 7电缆，更常被称为Cat7、七类网线或Cat-7电缆，是一种高端数据传输跳线，用于构建有线千兆以太网设置的核心基础设施。 它是一种屏蔽双绞线电缆，主要用于在直接连接的服务器、交换机和计算机网络之间以1Gbps或更高的数据传输速率实现高速以太网连接。

Cat7 is defined by ISO/IEC 11801. Taking a look at the specifications between Cat7 and Cat6A we have identical performance for all intents and purposes, regardless of the specification difference of 100 MHz, which means they will both run at the maximum 10 Gigabit speed.

2021年11月8日 · The AWG size of your ethernet cable has a significant impact on its performance. We’ll go through three of regular and the most popular AWG sizes such as 24AWG, 26AWG, and 28AWG. Cat5e, Cat6, and Cat6A cables all use these cables.

Data cable for structured premises and outdoor cabling, with rodent protection and increased UV protection (due to PE outer sheath). It is used for the transmission of digital and analogue voice, video and data signals. Suitable for all ICT network applications up to class F applications (600 MHz) in accordance with EN 50173-1 and ISO/IEC 11801.
