Unverified屏蔽层数越多抗干扰越好但线缆越硬、弯曲半径越大、越贵，家庭室内穿管布线用四屏蔽反而不好走线，双屏蔽更实用77% similarUnverified规格越高（Cat6a/Cat7）线越粗越硬，穿管占用空间大且弯折半径要求高，20mm穿线管内塞多根Cat6a容易穿不动，家用主干Cat6性价比与施工便利性最平衡75% similarUnverified带宽选5cm优于2.5cm窄带，宽带受力面积大、缠绕后压强分散不易勒变形箱体，也更耐磨不易断裂71% similarUnverified屏蔽线抗干扰强但线径粗、施工需接地、成本高；非屏蔽线柔软易施工，家用绝大多数场景抗干扰足够71% similarUnverified屏蔽等级越高抗干扰越强，但线材越硬越难布线、且需专业接地，家用高屏蔽往往性能过剩且施工麻烦70% similar
