## Summary description

Compact SFP28 optical transceiver BlueOptics R7D11A-BO supporting 25GBASE-SR operation over multimode fiber. Uses LC-duplex connector, 850 nm wavelength and supports link distances up to 100 m. Designed for 25 Gigabit Ethernet uplinks and switches; compatible with HPE Alletra systems for server and storage interconnects.

## Long description

The BlueOptics R7D11A-BO SFP28 transceiver is a compact optical module designed for 25GBASE-SR multimode fibre links. It operates at an 850 nm wavelength, uses an LC-duplex connector and supports link distances up to 100 metres. The module is intended for 25 Gigabit Ethernet uplinks, top-of-rack switches and server or storage interconnects and is listed as compatible with HPE Alletra systems.
Advantages
This SFP28 transceiver offers a small form factor that fits standard SFP28 ports, enabling high-density installations in data centre switches and servers. Support for 25GBASE-SR over multimode fibre provides cost-effective short-reach connectivity with low latency. The LC-duplex interface is widely used and simplifies integration into existing multimode fibre cabling plants. Compatibility with HPE Alletra environments helps reduce interoperability checks and accelerates deployment.
Suitable for
25 Gigabit Ethernet uplinks between switches and aggregation layers
Top-of-rack switch connections to servers and storage systems
Short-reach multimode fibre links within data centres or wiring closets (up to 100 m)
High-density switch deployments where SFP28 ports are available
When it may not be suitable
This transceiver is optimised for multimode fibre and short-reach links; it is not designed for single-mode long-haul connections. It will not extend beyond the specified 100 m range on standard multimode fibre and therefore is not appropriate for campus or metro links that require longer reach or single-mode optics.
Key specifications
Form factor: SFP28
Data rate: 25 Gbps
Wavelength: 850 nm
Connector: LC duplex
Maximum reach: up to 100 m on multimode fibre (OM3/OM4 dependent)
Application: 25GBASE-SR (short reach)
How to use
Install the transceiver into an available SFP28 slot on a compatible switch, router or host adapter following the device manufacturer’s installation instructions. Connect LC-duplex patchcords between the transceiver and the multimode fibre port of the remote device, observing correct transmit/receive orientation. After physical installation, verify link status in the network equipment management interface and confirm 25 Gbps operation and signal integrity using built-in diagnostics or network monitoring tools.
What to consider before purchase
Ensure your switch or server supports SFP28 modules and 25 Gbps operation
Confirm compatibility with HPE Alletra or other target equipment if vendor interoperability is required
Verify multimode fibre type (OM3/OM4) and cable length to ensure the 100 m reach is sufficient
Check that your existing patchcords use LC-duplex connectors
Usage recommendations
Use this module in short-reach multimode links within data centres; pair it with OM3 or OM4 multimode fibre and quality LC-duplex patchcords. Monitor link parameters after installation and keep fibre connectors clean to maintain signal quality.
