Product information

Description

The D-Link DEM-S2801SR is a high-performance SFP28 fiber optic transceiver module engineered for 25GBASE-SR networking environments. This module facilitates high-speed data transmission at rates up to 25000 Mbit/s, utilizing an 850 nm wavelength over multi-mode fiber optic cabling. Designed for seamless integration into enterprise-grade switches and routers, it provides a reliable solution for high-bandwidth connectivity requirements in modern data centers and server rooms.

Advantages

This transceiver offers the significant benefit of hot-swappable functionality, allowing network administrators to install or replace the module without powering down the host device or interrupting network traffic. This capability minimizes maintenance downtime and enhances operational flexibility. Furthermore, the module is fully compliant with international safety and industry standards, ensuring broad compatibility and stable performance across diverse networking infrastructures. Its compact design and efficient power consumption make it an ideal choice for high-density network deployments where space and energy efficiency are critical.

Suitable for

High-speed data center interconnects
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.
