Mining Flameproof Intrinsically Safe Ethernet Switch

The KJJ127 Mining Flameproof Intrinsically Safe Ethernet Switch is a new‑generation broadband communication device designed for underground coal mines. Compliant with IEEE 802.3 and IEEE 802.3u Ethernet standards, it delivers high‑speed networking capabilities with a total switching capacity of up to 10 Gbps, supporting the formation of fiber‑optic self‑healing ring networks that dramatically enhance system reliability and fault tolerance. The switch features eight gigabit optical ports (LC interface, 1310nm single‑mode fiber) with auto‑negotiation at 1000/100Mbps, transmit power of ‑10dBm to 0dBm, and receive sensitivity of ‑22dBm, ensuring long‑distance transmission up to 10 kilometers over single‑mode fiber (with up to eight splice points). Additionally, it provides eight Fast Ethernet electrical ports (10/100Mbps auto‑negotiation) with a maximum transmission distance of 100 meters over standard mining communication cables. Powered by AC127V and built with a rugged flameproof enclos…
