Network Module Lanview DEM-431XT-DD 10GBASE-SR SFP+ multimode 850 nm

Lanview DEM-431XT-DD is a 10GBASE-SR SFP+ multimode transceiver module designed for short-range fiber connections using an 850 nm wavelength. It provides hot-pluggable, compact 10 Gbps connectivity for servers, switches and storage systems, enabling high-speed uplinks and aggregation in data centers and enterprise networks. The module is intended for use in SFP+ ports and supports multimode fiber links over short distances with reliable signal performance.

Advantages

The module supports 10 Gbps data rates on multimode fiber with an 850 nm VCSEL light source, delivering low-latency, high-bandwidth links suitable for dense networking environments. Its SFP+ form factor enables hot-swap installation and compact port density, reducing rack space and simplifying upgrades. The device is interoperable with standard SFP+ interfaces, facilitating integration into existing network equipment that accepts SFP+ multimode transceivers.

Suitable for

• Short-range 10 Gbps uplinks between switches in data centers
• Server-to-switch high-speed connections
• Storage area network (SAN) aggregation and top-of-rack deployments
• Multimode fiber links within enterprise campus networks

How to use

Insert the Lanview DEM-431XT-DD module into an available SFP+ port on a compatible switch, server NIC or storage device while the host device is powered on or as permitted by vendor hot-swap guidelines. Connect duplex multimode LC fiber patch cables to the module, ensuring correct Tx/Rx orientation. Verify link status through the host device management interface and monitor signal indicators or port statistics to confirm 10 Gbps operation and link integrity.

Recommendations

Choose appropriate multimode fiber (OM3/OM4) and maintain proper patch cable routing and connector cleanliness to ensure optimal performance. Confirm compatibility with the host device's SFP+ port and firmware, and follow equipment vendor guidelines for insertion and removal to avoid connector damage. For longer distances or single-mode deployments, select a transceiver matched to the required fiber type and wavelength.
