TP-Link SM6110-LR Omada 25GBase-LR SFP28 Transceiver
Overview
The SM6110-LR is a hot-swappable optical transceiver designed for long-reach, high-speed data center and campus backbone deployments. It operates at dual rates—25.78 Gbps for 25G Ethernet and 10.31 Gbps for 10G Ethernet—allowing flexible integration into existing infrastructure without forcing a fork-lift upgrade. Operating over single-mode fiber (SMF) at 1310 nm wavelength, this transceiver delivers up to 10 km of reach, making it suitable for inter-building connectivity and core network segments where distance and speed both matter.
Compatibility
The SM6110-LR integrates with TP-Link Omada switching platforms and any standards-compliant 25G/10G SFP28 port. Verify your switch or NIC supports SFP28 form factor and is rated for 1310 nm single-mode operation before purchase. This is a passive optical interface—no active power negotiation occurs at the transceiver level.
Key Features
Dual-rate operation: Auto-negotiates between 25G and 10G, eliminating the need for separate SKUs when migrating segments or adding capacity incrementally. DDM (Digital Diagnostics Monitoring): Real-time temperature, bias current, transmit/receive power, and voltage telemetry—essential for unattended long-distance links where you need early warning of optical degradation. Low power draw (1.2 W): Reduces heat dissipation burden in high-density transceiver bays, a practical benefit in data center environments running 40+ transceivers per rack. Hot-swappable design: Install or replace without shutting down the port, minimizing service windows during maintenance or troubleshooting.
Installation Notes
Verify fiber polarity and cleanliness (UPC ferrule connectors require IEC 61300-3-34 grade 3 or better). A single-mode fiber reel rated for 1310 nm operation and a fusion splicer or LC/UPC patch panels rated for long-distance runs are prerequisite. Confirm switch firmware supports DDM readout if you plan to monitor real-time diagnostics.
