随着全球信息化高速公路的快速发展，局域网数字电缆得到了进一步的大规模应用，网络技术的飞速成倍增长以及接入网技术跳跃式发展，给信息的传输媒介提出了更高要求。
千兆以太网已经不能满足用户宽带要求，万兆比以太网（10Gbps）将成为主流技术。相对应的数字通信电缆需从超五类（100Mbps）、六类（200Mbps）向七类（600Mbps）、八类(1000Mbps) 产品发展，如何解决对高频屏蔽效果电磁波的反射和吸收，以及串音和衰减问题，成为本领域技术人员努力的方向。
发明内容
本发明的目的是提供一种具有屏蔽功能的通信线缆，该通信线缆提高了高频电磁波的反射和吸收，改善了串音和信号衰减，扩展了吸收频率的带宽且提高了产品性能的稳定性。
