D-Link 10km 25GBASE-LR Single-Mode SFP28 Transceiver

The D-Link DEM-S2810LR is a 25GBASE-LR SFP28 transceiver that brings 25 Gigabit Ethernet speed to switches and routers equipped with an open SFP28 slot. Built for single-mode 9/125 µm fiber, it can push data up to 10 kilometers, giving you a straightforward way to extend high-bandwidth links between buildings, data halls, or remote network nodes.

Installation is simple. The module is hot pluggable, so you can slide it into a compatible switch port and have the link come up without taking the system offline. Full compliance with IEEE 802.3by, IEEE 802.3cc, and the Multi-Source Agreement keeps interoperability issues to a minimum, whether you are adding it to a D-Link DMS 3130-30TS switch or another device that follows the same standards.

Operating at a 1310 nm wavelength, the DEM-S2810LR maintains a stable optical signal over long distances, making it a dependable choice for enterprise backbones, campus networks, disaster-recovery links, or any setup that needs consistent throughput and low latency across fiber.

If you are refreshing a rack, consolidating servers, or building out a new fiber run, this transceiver offers a quick, space-efficient path to higher bandwidth without replacing your existing switch chassis. Simply patch in the single-mode fiber, lock the module into place, and your 25 Gbit link is ready.
