产品应用

S/FTP为优化的6A结构设计,该产品应用于对电磁干扰要求极高的屏蔽保密系统,用于室内水平工作区布线,室内局域网布线。

使用特性

1. 在90米距离内提供500MHz带宽,典型应用速率为10Gbps。
2. 产品选用直径为0.58mm优质无氧铜为传输导体,电气传输性能可靠优异,达到并大大超过超六类系统指标。
3. 在4对双绞线线对外整体纵包厚度为0.06mm单面铝箔外加镀锡铜丝编织网屏蔽层,较非屏蔽电缆,在保证同等传输带宽水平前提下,SF/UTP型屏蔽线缆抗屏蔽干扰能力提高了25dB,可达到90dB,可用于对于需抗电磁干扰要求极高的使用环境,整体屏蔽系统具有极高的信号屏蔽性和保密性。
