D-Link DEM-S2810LR, Fiber optic, 25000 Mbit/s, SFP28, LC, 9/125 m, LR
D-Link s 25G SFP28 Module series are hot-swappable SFP28 transceivers that are plugged into SFP28 slots on switches and support 25G Ethernet. The transceivers use the Small Form-factor Pluggable 28 format (SFP28) connectors. The D-Link 25G SFP28 Module Series transceivers offer customers a wide variety of 25G Ethernet connectivity options for data centers, enterprise wiring closets, and service provider transport applications.
Hot Pluggable
All D-Link transceivers are hot pluggable. You can connect atransceiver while the system is powered on without causing any issues, and easily swap one for another without having to reboot the switch each time. This permits modules to be added or removed without interrupting the network, facilitating maintenance and greatly reducing downtime.
25G Ethernet speeds
The transceivers support 25G Ethernet, which results in very fast data transmissions of up to 25 Gbit/s. This is 25 times faster than Gigabit Ethernet and enables the switch to handle faster and higher data transmissions, making it very suitable for business needs.

| Performance | |
| SFP transceiver type | Fiber optic |
| Maximum data transfer rate The maximum speed with which data can be transmitted from one device to another. | 25000 Mbit/s |
| Interface type | SFP28 |
| Single-mode fiber (SMF) supported |
 |
| Fiber optic connector This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced. | LC |
| Fiber cable diameters supported (core/cladding) | 9/125 µm |
| SFP transceiver standard | LR |
| Maximum transfer distance The greatest distance over which the data/signal can be transferred. | 10000 m |
| Wavelength The distance over which a wave repeats itself. The wavelength determines the characteristics of the wave e.g. red light has a different wavelength to blue light. | 1310 nm |
| Tx power (min) | -5 dBmW |
| Tx power (max) | 2 dBmW |
| Rx power (min) | -13.3 dBmW |
| Rx power (max) | 0.5 dBmW |
| Fiber ethernet cabling technology | 25GBASE-LR |
| Features | |
| Hot-Plug support Device has hot-plug capability, which means that user can replace system components without shutting down the system. |
