## Summary description

BlueOptics DEM-431XT-BO is an SFP+ fiber optic transceiver supporting up to 10000 Mbit/s data rate with 850 nm wavelength. Designed for SFP+ interfaces, it provides short-range multimode connectivity for switches and servers. Silver-colored module, RoHS compliant, compatible with D-Link equipment and supplied as a single unit.

## Long description

BlueOptics DEM-431XT-BO is an SFP+ fiber optic transceiver designed for short-range multimode links. It supports a maximum data rate of 10 000 Mbit/s over an 850 nm wavelength and connects via an LC duplex connector. The silver-coloured, RoHS-compliant module is intended for SFP+ interfaces in switches, servers and other network equipment and is supplied as a single unit weighing approximately 20 g.
Advantages
The BlueOptics DEM-431XT-BO provides 10GBase-SR class short-range multimode fiber connectivity with a compact SFP+ form factor. Compliance with SFP+ MSA electrical and mechanical specifications ensures interoperability with compatible network hardware. The module’s 850 nm optics and LC duplex interface enable simultaneous transmit and receive on a two-fiber multimode link. RoHS compliance and a lightweight silver housing make it suitable for standard data center and enterprise deployments.
Suitable for
Short-range 10 Gbit/s connections between switches and servers over multimode fiber
Data center uplinks and aggregation links requiring SFP+ modules
Network hardware that accepts SFP+ form-factor transceivers with LC duplex connections
Environments where RoHS compliance and standardized MSA interoperability are required
When it may not be suitable
This transceiver is optimized for short-range multimode operation at 850 nm and is specified for distances up to around 300 m over suitable multimode fiber. It is not appropriate for long-distance single-mode fiber links or applications requiring wavelengths other than 850 nm. Compatibility depends on the host device supporting generic SFP+ optics; some vendors restrict or require specific firmware for third-party modules.
Key specifications
Interface type: SFP+
Maximum data transfer rate: 10000 Mbit/s
Optical wavelength: 850 nm
Connector: LC duplex
Typical reach: up to 300 m over multimode fiber (protocol- and fiber-dependent)
Product colour: Silver
Weight: approximately 0.02 kg
Compliance: RoHS
How to use
Install the DEM-431XT-BO into an available SFP+ slot on a compatible switch, server or network device until it latches. Connect LC duplex multimode fiber patch cords—observe correct transmit/receive orientation—and verify link status through the host device indicators or management interface. Ensure the host hardware supports the use of third-party SFP+ modules and, if available, enable digital diagnostic monitoring in the device to read real-time parameters where supported.
What to consider before purchase
Confirm that the target device accepts third-party SFP+ transceivers and supports DDM/DOM if monitoring is required
Verify the required fiber type (multimode) and patch-cord connector (LC duplex)
Ensure the link distance requirement aligns with short-range 850 nm multimode operation (typical up to 300 m)
Check that 10GBase-SR protocol support matches your network equipment and application
Usage recommendations
For optimal performance, use high-quality multimode fiber patch cords and maintain clean LC connectors. Validate link parameters after installation and, where available, monitor optical power, temperature and supply voltage through the host’s diagnostics to detect degradation early. When interoperating with vendor-specific equipment, test a single module first to confirm compatibility before wide deployment.
