TP-Link SM5110LSB-10 10Gbase-BX Single-Mode WDM SFP+ Module
Overview
The SM5110LSB-10 is a wavelength-division multiplexed (WDM) bi-directional SFP+ transceiver designed for long-haul, point-to-point 10 Gigabit Ethernet links over single-mode fiber. TX wavelength 1270nm, RX wavelength 1330nm — this asymmetric pairing allows simultaneous bidirectional traffic on a single fiber strand, reducing cabling requirements in extended-distance backbone and inter-building backbone scenarios. The 10km operational range suits campus networks, industrial fiber runs, and remote site aggregation where backbone distance exceeds standard multimode limits (typically 300m). LC/UPC connectors ensure low back-reflection and compatibility with standard fiber patch panels and infrastructure.
Compatibility
The SM5110LSB-10 plugs into any SFP+ port on TP-Link Omada-series managed switches — including the TL-SG3452, TL-SG3452X, TL-SG3728X-RP, and similar 10 Gigabit-capable models. Verify your switch datasheet for SFP+ slot count and supported module types; all current Omada 10G-capable platforms accept standard LC/UPC SFP+ modules. When paired with a matching SM5110LSB-10 on the far end, the module delivers 10Gbps full-duplex throughput over a single fiber pair — meaningful for network operators consolidating fiber runs or extending backbone reach without trenching new cable.
Installation Notes
Single-mode fiber requires precise termination and handling; use only certified SC or LC/UPC connectors rated for single-mode. Verify fiber type (OS1 or OS2 preferred) and total link loss before deployment. Clean connector endfaces with lint-free wipes and IPA; contamination on SM fiber causes significantly higher insertion loss than on multimode. Module insertion/removal requires no tools; gently push until it clicks. Operating temperature range not specified in available evidence — consult TP-Link datasheet or support for environmental limits if deploying in non-standard conditions.
