4pairs are Category 5 network cables.
Category 5 cable, referred to as Cat.5, is a twisted pair cable used in computer networks. It is also a multimedia cable used for data, voice and other information communication services. It is widely used in Ethernet , In the broadband access project, its quality is directly related to the transmission quality of information communication. Due to the development of optical fiber and communication technology, the impact of twisted pairs on communication quality is gradually decreasing.
Category 5 lines were born with 100Mbps Fast Ethernet, but with the development of network technology, the physical layer transmission protocol 1000Base-T based on Category 5 lines has made Category 5 lines Class Cable also has the transmission capability of Gigabit Ethernet (1,000,000,000 bit/s). This technology achieves a smooth transition from 100M to Gigabit while retaining the original cable. Therefore, after the devices at both ends automatically negotiate, the Category 5 line can operate at a 100MHz operating frequency under 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet) and other technologies to undertake Ethernet at different rates. transmission medium. To ensure transmission quality, the transmission distance of Category 5 lines is generally within 100 meters.
More applications of Category 5 cable
Category 5 cable, as an 8-core copper cable with good performance, can naturally play a role in signal transmission other than Ethernet. For example, it carries voice and video. In some cases, Category 5 can carry multiple traditional phone lines on a single cable. There are several options for transmitting analog or digital video over cable. HDBaseT (10.2 Gb/s) is one such solution.
Qualified unshielded Category 5 twisted pair cable
Shielded twisted pair cable
Shielded Category 5 twisted pair cable There is a metal film for shielding, which has better anti-interference performance. Some readers may ask why not use shielded Category 5 twisted pair? This is because shielded twisted pair cable requires that the entire system be shielded, including cables, sockets, crystal heads and distribution frames, etc., and the building needs to have a good grounding system. However, in actual construction, it is difficult to ground everything, making the shielding layer itself the biggest source of interference, resulting in performance that is even far inferior to unshielded twisted pair UTP. Therefore, unless there are special needs, only unshielded twisted pairs are usually used in integrated wiring systems.

2.5g网口用超五类网线,可以接千兆网线。2.5G口就是2.5Gbps速率的网络接口,实际速率通常按2500Mbps计算;而超五类网线(cat 5e)完全可以应对2.5Gbps和1000Mbps的传输需求。超五类非屏蔽双绞线是在对五类屏蔽双绞线的部分性能加以改善后出现的电缆,不少性能参数,如近端串扰、衰减串扰比,回波损耗等都有所提高,但其传输带宽仍为100MHz。

“hsyv-6”是六类双绞线(网线);hsyv表示的是双绞线,“6”表示的是CAT6,也即六类,六类网线最高支持千兆网络,是百兆五类网线的升级版,六类双绞线在外形上和结构上与五类或超五类双绞线都有一定的差别,不仅增加了绝缘的十字骨架,将双绞线的四对线分别置于十字骨架的四个凹槽内,而且电缆的直径也更粗。

超六类网线标志是6a,其完整标识是CAT6A;CAT6E属于CAT6改进版,但不是CAT6A;超六类网线和六类网线的内部结构中一般都添加了具有绝缘效果的十字骨架,并且都会把4对双绞线分别排列在十字骨架的4个凹槽内,不过超六类网线内部的十字骨架一般都是使用齿轮状的有线槽形状,而六类网线的十字骨架一般都是一字隔离的。

hsyv-5e是超五类网线;hsyv表示的是线的结构,5e表示的是超五类,它的传输频率高达100MHz,是千兆网线,可用于千兆网络中使用,且hsyv-5e中线对的扭绕度较为密集,信号传输快,质量较好,耐用性更佳。

网线插着却显示无法识别网络解决方法有三种分别是:1、拔掉网线,重新启动路由器;2、按Win+X,选择设置,点击网络和Interner,选择以太网之后点击更改适配器选项,点击本地连接选择禁用之后再次点击选择启用即可;3、点击网络和Internet界面里的状态,再选择弹出界面里的网络重置,点击立即重置后电脑5分钟内重启完成重置即可。

hsyu5e是超5类双绞线,具有衰减小、串扰少的特点,并且具有更高的衰减与串扰的比值(ACR)和信噪比(signal to noise ratio)、更小的时延误差,性能得到很大提高。hsyu5e的的传输频率高达100MHz,是千兆网线,可用于千兆网络中使用,且hsyv5e中线对的扭绕度较为密集,信号传输快,质量较好,耐用性更佳。

b类网线线序是指b类网线制作的线序,按照T568B的标准接线,12345678分别是橙白、橙、绿白、蓝、蓝白、绿、棕白、棕,网线两端都按照这个线序做好水晶头。

4pairs是五类网线。五类线是一种计算机网络中使用的双绞式电缆,也是数据、话音等信息通信业务使用的多媒体线材,被广泛应用于以太网、宽带接入工程中,其质量的优劣,直接关系到信息通信的传输质量。
