Small and medium-sized enterprises (SMEs) face soaring network demands: e-commerce requires real-time inventory sync, remote training relies on 4K streaming, and logistics uses IoT for warehouse efficiency. 75% of SMEs report customer dissatisfaction due to network lag, while 60% suffer efficiency drops from cloud delays. Transitioning from 1Gbps to multi-gigabit speeds, IEEE 802.3bz enables Category 6 systems to deliver 2.5Gbps–5Gbps over 250MHz bandwidth—2–5x faster than legacy 5e systems. Unlike costly Category 6A (10Gbps at 500MHz), Category 6 offers budget-friendly multi-gigabit readiness with 30–50% lower material and installation costs. This passage detailedly explains Category 6 cabling system's features and Zhaolong Category 6 cabling system's advantages.
