SFP28 transceiver module BlueOptics SFP28-25G-ESR-UQ 25000 Mbit/s 850 nm

The BlueOptics SFP28-25G-ESR-UQ is an SFP28 fiber optic transceiver module engineered for 25 Gbit/s links over multimode fiber. Operating at an 850 nm wavelength, this compact module provides a standard SFP28 interface for insertion into compatible network equipment. With a lightweight metal housing and a small form factor, it supports high-density deployments in data centers and enterprise aggregation switches where reliable short-reach connectivity is required.

Advantages

This SFP28 transceiver supports a 25,000 Mbit/s maximum data transfer rate and a standard 850 nm VCSEL wavelength, enabling high-speed short-range connections. The compact SFP28 form factor ensures compatibility with a wide range of modern switches and servers while the silver metal housing contributes to mechanical robustness and thermal dissipation. Its low weight simplifies handling and installation in dense equipment racks.

Suitable for (tasks / use cases)

• Short-reach 25 Gbit/s uplinks in data centers
• High-performance server-to-switch connectivity
• Top-of-rack and aggregation layer links over multimode fiber
• Hardware refreshes where SFP28 slots are available

How to use

Before installation, verify that the host device supports SFP28 modules and the required 25 Gbit/s optics. Insert the transceiver into an empty SFP28 slot until it clicks into place, ensuring correct orientation. Connect the appropriate multimode fiber cable with the correct connector type for the transceiver. After physical installation, confirm link status and configure interface parameters on the host switch or server as needed. For removal, disengage any retention mechanism and pull the module straight out.

Recommendations

Use multimode OM3/OM4 fiber for best performance at 25 Gbit/s and keep optical connectors clean to maintain link quality. Observe equipment vendor compatibility lists if strict interoperability is required.
