48-Port SFP Switch

48-port switches with SFP ports provide high-density Ethernet connectivity with fiber uplinks for scalable, high-speed network deployments.Key FeaturesPort Configuration: These switches typically offer 48 Gigabit Ethernet ports for standard network devices, combined with 4–6 SFP/SFP+ ports for fiber uplinks, enabling long-distance or high-speed connections . Some models, like the MikroTik CRS354-48P-4S+2Q+RM, also include QSFP+ ports for 40 Gbps uplinks . PoE Support: Many 48-port switches provide Power over Ethernet (PoE), supporting standards such as 802.3af/at, allowing devices like IP cameras, phones, and access points to be powered directly through the Ethernet cable . Performance: High-end models offer non-blocking throughput up to 336 Gbps and forwarding rates exceeding 200 Mpps, ensuring minimal latency and high-speed data transfer across all ports . Layer 3 switches support routing, VLANs, and advanced network management. Management and Reliability: Managed switches include features like VSU virtualization, link aggregation, dual power supply redundancy, and CPU protection policies to maintain network stability and security . They often support centralized management platforms for monitoring, configuration, and rapid deployment. Use Cases: These switches are ideal for enterprise networks, campus networks, and data centers, where high port density, fiber uplinks, and PoE are required. They allow for scalable network expansion and reliable connectivity for both short-range and long-distance connections.Example ModelsRuijie RG-S5310-48SFP4XS-E: 48 GE ports, 4 SFP+ uplinks, Layer 3 managed, supports VSU virtualization and advanced security policies .Ruijie RG-CS85-48SFP4XS-D: 48 x 1GE SFP ports, 4 x 10G uplinks, dual Flash chips for boot redundancy, power module failover, and dual-stack IPv4/IPv6 support .MikroTik CRS354-48P-4S+2Q+RM: 48 x 1G RJ45 ports with PoE, 4 x 10G SFP+ ports, 2 x 40G QSFP+ ports, 336 Gbps switching capacity, and preinstalled RouterOS/SwitchOS for easy deployment . These switches provide a balance of high port density, fiber uplinks, PoE support, and advanced management, making them suitable for modern enterprise and campus network environments.
