Suitable for upgrading or replacing optics in data centers and enterprise networks.

## Long description

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.
Suitable for
 Short-range multimode fiber links in data centers and server rooms
 10 Gbit/s uplinks between switches and aggregation devices
 Interconnects between servers and top-of-rack switches
 Replacing or upgrading SFP+ optical interfaces in enterprise networks
Key specifications
 Data rate: 10 Gbit/s
 Wavelength: 850 nm (multimode)
 Form factor: SFP+ (hot-pluggable)
 Reach: short-range multimode fiber links (typical for 850 nm VCSEL optics)
 Connector type: duplex LC compatible with SFP+ multimode transceivers
 Typical applications: server-to-switch and switch-to-switch uplinks
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.
Usage 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.
