This 25G SFP28 SR transceiver is built for short-reach, high-bandwidth connections where cost efficiency and reliable performance matter. Designed to support 25.78Gb/s data rates, it provides a straightforward upgrade path from 10G to 25G in data centers and enterprise networks, especially where multimode fiber is already in place.

At its core, the transceiver uses an 850nm VCSEL transmitter and a GaAs PIN photodiode receiver. It supports link distances up to 70 meters on OM3 multimode fiber and up to 100 meters on OM4 multimode fiber. That reach covers most intra-rack and adjacent-rack connections, making it a practical choice for server-to-switch links and top-of-rack deployments.

The transceiver runs on a 3.3V DC power supply with low power consumption, keeping heat generation under control in dense environments. It operates within a case temperature range of 0°C to 70°C, suitable for typical data center conditions. The electrical interface follows SFF-8431, and the transceiver complies with SFP28 MSA and SFF-8432 specifications, ensuring it works with a wide range of SFP28-compliant switches and servers.

For teams looking to scale network capacity without re-cabling existing multimode fiber runs, this transceiver offers a clean, plug-and-play solution. It is hot-pluggable, requires no special configuration, and includes built-in digital diagnostic functions for basic monitoring.

FAQ

Q: What is the most common use case for this 25G SFP28 SR transceiver?

A: This transceiver is primarily used for server-to-top-of-rack (ToR) switch connections in data centers. As servers increasingly adopt 25G network interfaces, this transceiver provides the ideal link to connect them to the aggregation switch, efficiently upgrading the last hop of the network from 10G to 25G.

Q: Does the transceiver support digital diagnostics, and what can I see from it?

A: Yes, it includes built-in digital diagnostic monitoring (DDM). Through your switch's management interface, you can view real-time parameters such as temperature, supply voltage, transmit optical power, and receive optical power. This is helpful for troubleshooting and for catching potential issues before they cause link failures.
