The EDS-518A-SS-SC-80 is a high-performance industrial managed Ethernet switch by Moxa, specifically engineered for long-distance fiber communication. It features 14 Fast Ethernet ports (10/100BaseT(X)), 2 single-mode SC fiber ports supporting up to 80 km transmission (100BaseFX), and 2 combo ports supporting either 10/100/1000BaseT(X) or 1000BaseSFP modules for flexible Gigabit connectivity.

Designed for reliable operation in demanding environments, this switch includes advanced redundancy with Turbo Ring, Turbo Chain, and STP/RSTP/MSTP protocols, and supports VLAN, QoS, IGMP snooping, and bandwidth management. Comprehensive security features include HTTPS, SSH, TACACS+, RADIUS, and port lock. The EDS-518A-SS-SC-80 also supports industrial protocols like Modbus TCP and EtherNet/IP, ensuring seamless integration in automation networks.
