Lightwin 25 Gbit SFP28 LR transceiver, 10km, DDM, LC-duplex, singlemode (LWO-SFP28-LR-BT)

The Lightwin LWO-SFP28-LR-BT stands out with its low power consumption under 1.0 W and integrated digital diagnostics, making it a smart choice for dense 25G deployments where energy efficiency and remote monitoring matter. Unlike generic SFP28 modules, this unit pairs a DFB laser with a commercial temperature range to deliver consistent 10 km reach over standard single-mode fibre.

Highlights

• 25GBASE-LR compliant for 25 Gigabit Ethernet links up to 10 km
• Hot-swappable SFP28 MSA form factor with LC duplex connector
• DDM/DOM support for real-time monitoring of temperature, voltage, and optical power
• Low power consumption (< 1.0 W) reduces operating costs in high-density racks
• RoHS compliant and built for 0°C to 70°C operating environments

In daily use

Deploy this transceiver in data centre interconnects, enterprise backbone links, or any 25G Ethernet network that requires reliable long-distance transmission over single-mode fibre. The 1310 nm DFB laser ensures stable signal integrity across the full 10 km reach, while the LC duplex interface simplifies cabling. Hot-swap capability allows you to replace or add modules without powering down the switch, minimising downtime. Digital diagnostics give you visibility into link health, helping you proactively address issues before they impact performance.
