TP-Link SM5110LSA-10 10Gbase-BX Single-Mode WDM SFP+ Module
Overview
The SM5110LSA-10 is a 10 Gigabit bi-directional SFP+ transceiver module designed for extended single-mode fiber deployments. It uses wavelength-division multiplexing (WDM) to transmit at 1330nm and receive at 1270nm, enabling full-duplex 10G communication over a single fiber strand up to 10 km. This reduces fiber infrastructure costs in campus security networks, warehouse automation systems, and multi-building IP surveillance installations where distance exceeds standard multimode reach.
Compatibility
The SM5110LSA-10 integrates into any TP-Link Omada-series switch or managed networking device equipped with SFP+ slots. Verify your switch or access point datasheet for SFP+ cage support and firmware version before ordering. Compatible with industry-standard LC/UPC connectors on both module and fiber patch panels.
Installation Notes
Single-mode fiber requires precise polarity alignment. Pair transmit (TX) wavelength 1330nm on one end with receive (RX) wavelength 1270nm on the far end, or use WDM-matched module pairs. Verify fiber type certification (single-mode, OS2 or equivalent) before installation. Exceeding 10 km distance will degrade signal and introduce frame loss. Module operates at 0–70°C; ensure switch placement and cabling routes avoid temperature extremes in outdoor or warehouse environments.
