线材越长信号衰减越大，长距离要么加粗线径（更贵更硬）要么用光纤（贵且单向不可弯折收纳），短距离追求柔软则牺牲传输余量

Unverified线缆越长越粗越贵，但带宽保持能力越强；1米内可放心选无源铜缆，3米以上高刷场景性价比反而是光纤DP线更优（细软且无衰减）80% similarUnverified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75% similarUnverified线径越粗压降越小但柔韧性越差、走线越难，短距离（<1m）取电优先保证线径，长距离布线需在粗线径与走线便利间权衡，必要时提高一个线径规格补偿压降74% similarUnverified扎带宽度越宽承重越大但穿孔要求也越大，且过宽扎带弯曲半径大不适合捆扎细软线材；细扎带灵活但易勒伤线缆绝缘层73% similarUnverified内径选择过大不建议购买——收缩后仍松动无法贴合线缆，起不到绝缘固定作用；宁可选偏小规格靠收缩收紧73% similar
