SFP+ Transceiver Module BlueOptics DEM-431XT-DD-BO 10 Gbit/s 850 nm

BlueOptics DEM-431XT-DD-BO is an SFP+ transceiver module that supports 10 Gbit/s data transfer over multimode fiber using an 850 nm wavelength. Engineered for short-range links, this hot-pluggable module fits SFP+ cages and is intended for rack switches, servers and fiber uplinks in data centers and enterprise network environments. The module is compatible with standard SFP+ form factor requirements and is intended for use where reliable, high-speed short-reach optical connectivity is required.

Advantages

The transceiver offers 10 Gbit/s throughput on multimode fiber with an 850 nm VCSEL design for short-range connections, enabling straightforward upgrades of existing SFP+ ports without replacing switching hardware. Its hot-pluggable design allows insertion and removal without powering down equipment, and the SFP+ form factor ensures broad physical compatibility with modern network devices. The module supports common short-reach link budgets suitable for typical server-to-switch and switch-to-switch uplinks in rack environments.

How to use

Install the transceiver by inserting it into an available SFP+ slot on a switch, server NIC or other network device until it seats and the retention latch engages. Connect duplex multimode fiber with LC connectors to the module ports, ensuring correct transmit/receive orientation. The module is hot-pluggable, so it can be installed or removed while the host device is powered, but follow your equipment vendor’s ESD and handling procedures. After physical installation, verify link status and speed on the host device and configure interface parameters as required by your network setup.

Recommendations

Use multimode fiber (OM3/OM4 recommended for optimal short-reach 10 Gbit/s performance), keep connectors clean, and ensure proper polarity when mating duplex LC connectors. Confirm compatibility with your network equipment firmware and interface settings before deployment to avoid link negotiation issues.
