Two-fiber four-electric PoE switch

A two-fiber, four-electric PoE switch provides two SFP fiber ports for long-distance connectivity and four PoE/PoE+ Ethernet ports to power devices like cameras or access points over a single cable.Key FeaturesFiber and Ethernet PortsTwo SFP fiber ports (1Gb) allow high-speed, long-distance connections using compatible SFP modules, ideal for linking remote network segments or outdoor devices .Four PoE/PoE+ RJ45 ports provide both data and power to connected devices, supporting IEEE 802.3af (15W) and 802.3at (30W) standards . Power and PoE BudgetTotal PoE power ranges from 75W to 120W, depending on the model, allowing full 30W per port for PoE+ devices .Some models include redundant DC inputs or built-in battery support for backup power, ensuring uninterrupted operation . Performance and ConnectivityEthernet ports support 10/100/1000 Mbps, auto-negotiation, and auto-crossover for plug-and-play installation .Fiber ports extend connectivity beyond the 100m limit of copper Ethernet, with some industrial switches supporting distances up to several kilometers with appropriate SFP modules . Industrial and Outdoor ReadinessMany switches are ruggedized, with metal enclosures, IP40 to IP66 ratings, and operating temperature ranges from -40°C to +85°C, suitable for harsh environments .Features like surge protection, DIN-rail or wall mounting, and fanless designs enhance reliability in industrial or outdoor deployments . Management and MonitoringOptions include unmanaged plug-and-play switches for simple deployments or managed switches with Layer 2 features for monitoring, VLANs, and diagnostics .Some models, like Altronix, include LINQ technology for remote monitoring of power and port status .Use CasesSurveillance systems: Powering IP cameras while connecting them over fiber to a central NVR.Industrial IoT: Connecting sensors, PLCs, and access points in factories or outdoor facilities.Outdoor networking: Linking remote buildings or outdoor devices where fiber is required for distance or interference immunity.Smart transportation or city infrastructure: Providing reliable PoE and fiber connectivity for traffic cameras, access points, and sensors.Example ModelsAltronix NetWaySP4LWPX: 2 SFP ports, 4 PoE+ ports, 75W total PoE, IP66 outdoor enclosure, battery backup support .Intellinet Industrial 4-Port PoE+ Switch: 2 SFP ports, 4 PoE+ ports, 120W power budget, -40°C to 75°C operation .Comxus 4-Port Managed Industrial PoE Switch: 2 SFP uplinks, Layer 2 management, rugged metal enclosure, -40°C to +85°C .MokerLink 4-Port PoE Switch: 2 uplink ports, 78W total PoE, plug-and-play, supports extended PoE distances up to 250m at 10 Mbps . These switches are ideal for scenarios requiring both fiber uplinks for long-distance connectivity and PoE for powering devices, combining reliability, industrial-grade durability, and simplified deployment.
