Enterprise network backbone upgrades
Service provider transport applications
High-density server-to-switch connectivity
When it may not be suitable
This module is designed specifically for short-range multi-mode fiber applications up to 100 meters and will not function over long-distance single-mode fiber links. It is also incompatible with hardware that does not support the SFP28 interface standard.
Key specifications
Data transfer rate: 25000 Mbit/s
Maximum distance: 100 meters
Wavelength: 850 nm
Connector type: LC
Interface: SFP28
Input voltage: 3.3 V
How to use
To install the D-Link DEM-S2801SR, simply insert the module into an available SFP28 port on your network switch or router. The device is hot-pluggable, meaning the system does not need to be powered off during installation. Once inserted, connect the appropriate multi-mode fiber optic cable with an LC connector to the transceiver. The system should automatically detect the module and establish the link. Ensure that the fiber cable is clean and properly seated to maintain signal integrity.
What to consider before purchase
Verify that your network hardware supports the SFP28 standard
Ensure your fiber optic cabling is multi-mode and compatible with LC connectors
Confirm that the required link distance does not exceed 100 meters
Usage recommendations
For optimal performance and longevity, avoid touching the optical connector surface and keep the protective dust cap on the module whenever it is not connected to a fiber cable. Ensure the operating environment remains within the specified temperature and humidity ranges to prevent signal degradation.
