SFP+ Transceiver TP-Link TL-SM5110-LR

The TL-SM5110-LR is a 10GBASE-LR SFP+ transceiver designed to extend 10Gbps Ethernet links over single-mode fiber. Operating at 1310 nm, it enables full-duplex 10G Ethernet connections over distances up to 10 km when used with 9/125 µm single-mode fiber.

Advantages

This SFP+ module provides long-reach connectivity for 10Gbps networks, supporting reliable full-duplex data transfer and compatibility with standard 9/125 µm single-mode fiber. Its 1310 nm wavelength and LR specification make it suitable for links up to 10 km, allowing straightforward integration into existing Ethernet infrastructures that require extended distance without changing transmission equipment.

Key specifications
