4 Optical Dual-Ring Network Switch
A 4 Optical Dual-Ring Network Switch is an industrial-grade managed switch with four fiber optic ports designed for high-reliability ring topologies, providing fast failover and redundancy in critical networks.OverviewA 4 Optical Dual-Ring Network Switch is a network device that supports fiber optic ring topologies, where each node connects to two others to form a closed loop. This design ensures redundant data paths, allowing traffic to reroute in the event of a link failure, which is essential for industrial automation, smart grids, surveillance, and other real-time applications . Dual-ring capability means the switch can participate in primary and backup rings, enabling millisecond-level recovery from network interruptions .Key FeaturesPort Configuration: Typically includes 4 fiber optic ports (FX) and additional RJ45 Ethernet ports (TX), such as the EL100-2MA with 4 FX and 4 TX ports .Redundancy Protocols: Supports Media Redundancy Protocol (MRP) or similar ring protection protocols, achieving recovery times under 300 ms .Industrial Design: Ruggedized for harsh environments, with wide operating temperature ranges (e.g., –25 °C to +60 °C) and DIN rail or wall mounting options .Power Redundancy: Dual power inputs with hot-swappable capability prevent downtime from single power failures .Management and Monitoring: Web GUI, SNMP, VLAN support, port mirroring, QoS, and alarm relay outputs for system events .Fiber Distance: Single-mode fiber support can range from 20 km to 120 km depending on the model .ApplicationsThese switches are ideal for industrial Ethernet networks where uptime is critical. Common use cases include:Factory automation and process controlRailway and transportation communication systemsPower and utility networksCampus or large facility backbone networks By combining dual-ring topology with intelligent redundancy protocols, these switches form a self-healing network core, ensuring continuous data transmission even during fiber cuts or device failures .Example ModelsGAOTek 16GE + 4 OPTIC Switch: Industrial rail design, 16 Gigabit electrical ports plus 4 optical ports, suitable for high-data applications like video transmission .EL100-2MA 4TX/4FX Managed Switch: Supports MRP, PROFINET certified, with recovery time
