Overview
AirLive POE-GSH2404M-400 is an L2+ managed 28-port Gigabit PoE+ switch including 24 PoE ports and 4 Gigabit SFP/TP combo ports with high 400W PoE power. Each PoE port is 802.3at/af compliant of up to 30W, automatically adaptive. It supports comprehensive SNMP management function such as IGMP Ring Network, VLAN Division, Port aggregation, QoS port mirroring, bandwidth control. Providing VLAN Division Policy function for setting higher priority for Video Conference, Surveillance, Voice, or data that prevents package loss or lags. Furthermore, the PoE watchdog can detect and restart crashed IPCAM or PD, the best 24/7 PoE device guard. No manual is required, and it can provide timely and reliable solutions for later operation and maintenance of the projects.






Fiber for Long Distance
Fiber optic technology is used for long distance communication due to its high bandwidth capacity and immunity to electromagnetic interference. Fiber optic cables are made of thin glass or plastic fibers that carry light signals over long distances, providing fast and reliable data transmission. This makes fiber optics ideal for applications where large amounts of data need to be transmitted over long distances, such as in long-haul telecommunications and data center networks.
