This surface box has an ABS/PC body, which is impact-resistant and meets flame-retardant standards for safe use. Its built-in shielding layer isolates electromagnetic interference, fitting high-interference environments; the PCB optimizes signal paths to reduce attenuation, stably supporting 100Mbps transmission. Two RJ45 ports are compatible with Cat5e cables, connecting computers, printers, etc. simultaneously. With a desktop-friendly design for easy installation, some models have dust covers to prevent dust accumulation. Compact and convenient, it supports multi-device access in high-interference scenarios, meeting office data interaction and device networking needs.
