MiniGBIC Module TP-Link TL-SM311LM

The TL-SM311 series Multi-mode MiniGBIC fiber module (50/125µm or 62.5/125µm) supports 1.25 Gbps data rate, LC duplex connector and 850 nm wavelength with a reach up to 550 m. It is compatible with a range of TP-Link managed and smart switches for extending Ethernet links over multimode fiber.

Advantages

The module offers a compact MiniGBIC form factor for flexible deployment and supports common multimode fiber types. It is compatible with multiple TP-Link switch models including T3700G-28TQ, TL-SG5412F, TL-SG5428, TL-SL5428E, TL-SG3210, TL-SG3216, TL-SG3424, TL-SG3424P, TL-SL3428, TL-SL3452, TL-SG2210P, TL-SG2216, TL-SG2424, TL-SG2424P, TL-SG2452, TL-SL2210, TL-SL2218, TL-SL2428, TL-SL2452 and MC220L.

Key specifications

• Fiber type: Multi-mode (50/125 µm or 62.5/125 µm)
• Data rate: 1.25 Gbps
• Maximum distance: 550 m
• Connector: LC duplex
• Wavelength: 850 nm
• Form factor: MiniGBIC (SFP)

How to use

Insert the MiniGBIC module into the SFP slot of a compatible TP-Link switch until it clicks, then connect LC duplex multimode fiber cables to the module. Ensure the connected switch ports are configured as required for your network (auto-negotiation or fixed settings) and verify link status in the switch management interface. Use matching fiber type and quality to achieve the specified 550 m range.

Recommendations

Use multimode fiber (50/125 µm or 62.5/125 µm) and LC duplex connectors that meet industry standards; keep fiber connectors clean and avoid tight bends to maintain optimal signal quality.
