The Huawei S5731S-L4T2S-RUA is a 4-port Gigabit fiber-ready switch ideal for compact network expansion.

Key Specifications

• Downlink Ports: 4 x 10/100/1000BASE-T ports for connecting workstations, PCs, or office devices .
• Uplink Ports: 2 x GE SFP ports for fiber-optic connections, plus 1 x GE port with an SC connector (TX1310 nm/RX1490 nm) for long-distance fiber backhaul .
• Power: AC-powered with an included 12V DC adapter; local plug options are available .
• Design: Fanless and whisper-quiet (0 dB), suitable for desk or office placement .
• Energy Efficiency: Ultra-low power consumption, part of Huawei's green energy design .
• Optical Module Compatibility: Supports Huawei e-SFP-GE-SX-MM850 and SFP-GE-LX-SM1310 modules for multimode or single-mode fiber connections .
• Installation Options: Wall-mount, desk-mount, or DIN rail installation with included brackets .

Features and Benefits

• Cost-Effective Gigabit Expansion: Provides dedicated Gigabit Ethernet ports without PoE, reducing cost for small office or remote unit deployments .
• Dual SFP Uplinks: Enables high-bandwidth, long-distance fiber connections to central switches, supporting ring or redundant topologies .
• Zero-Configuration Setup: Managed entirely by the central switch, eliminating the need for local IP configuration or complex CLI setup .
• Quiet Operation: Fanless design ensures silent operation, ideal for office environments .

Fiber Connectivity Considerations

• Use multimode fiber jumpers for multimode SFP modules and single-mode fiber jumpers for single-mode SFP modules .
• Ensure the fiber connector type matches the SFP interface (e.g., SC connector for SFP-GE-LX-SM1310) to maintain proper connectivity .
• Determine fiber length based on onsite cabling distance to optimize signal quality . This switch is particularly suitable for small office networks, remote units, or compact network expansions where fiber uplinks are required for high-speed connectivity, and a quiet, energy-efficient solution is preferred.
