TP-Link SM6110-SR Omada 25GBase-SR SFP28 LC Transceiver
Overview
The SM6110-SR is a pluggable optical transceiver rated for multimode fiber backhaul in enterprise and warehouse automation networks. It operates at dual rates—25.78 Gbps for high-speed fabric links and 10.31 Gbps for backward compatibility with legacy 10G infrastructure—allowing you to retire equipment in phases without ripping out fiber runs. The 850 nm wavelength and LC/UPC duplex connector make it a standard fit across TP-Link Omada switches and third-party systems supporting SFP28 modules. Hot-swappable design means you can replace failed transceivers without powering down the chassis.
Compatibility
The SM6110-SR plugs into any TP-Link Omada switch with SFP28 slots. Verify your upstream switch model supports 25G SFP28 transceivers; older 10G SFP+ slots require different optics. The transceiver operates across both rates transparently—auto-negotiation is not required if you manually configure the link speed on both ends. DDM (Digital Diagnostic Monitoring) support enables real-time monitoring of optical power, bias current, and module temperature through your switch management interface, critical for predictive maintenance in unattended remote sites.
Installation Notes
At 25.78 Gbps, plan fiber runs to 100 m maximum on OM4 multimode (70 m on OM3). If you need longer distances, TP-Link offers single-mode variants; contact your systems engineer to verify fiber inventory. Keep LC connectors clean—dust on the ferrule degrades signal and triggers DDM alarms. The low power consumption profile minimizes heat load in high-density switch configurations. Confirm your switch firmware supports SFP28 speed negotiation; some older Omada releases lock to 10G and require a firmware update to unlock 25G rates.
