DEM-310GT D-Link Server Transceiver

Enterprise 1GbE SFP Long-Reach Singlemode Optics for Fibre Uplinks with the DEM-310GT

The DEM-310GT is a D-Link 1GbE SFP transceiver module engineered for stable 1000BASE-LX/LR-class connectivity on enterprise switches, routers, and SFP-based NICs. Designed for long-distance singlemode fibre links, the DEM-310GT operates at 1310 nm and supports up to 10 km reach, enabling consistent uplinks and access aggregation without redesigning the copper edge.

By using the SFP form factor, the DEM-310GT integrates cleanly into modular network architectures where port density and serviceability matter. Its LC duplex optical interface supports structured fibre plant deployment and straightforward cross-connect practices. The DEM-310GT fits PCIe-attached server networking indirectly by extending the optical domain from SFP NICs to distribution switches, helping standardise 1GbE transport for management networks, out-of-band paths, and legacy application tiers requiring deterministic Layer 2 connectivity.

Why Choose the DEM-310GT?

The DEM-310GT is a pragmatic choice for enterprises that need predictable 1GbE optical reach with minimal operational overhead. It supports a strong density-to-performance profile by converting standard SFP ports into long-reach singlemode uplinks, improving scalability across IDF-to-MDF runs, campus segments, and data centre rows while maintaining familiar Ethernet operational models.

D-Link designs optics like the DEM-310GT to align with enterprise deployment standards, focusing on interoperability within supported platforms, consistent link behaviour, and reliability for always-on network services. This approach helps IT teams keep fibre upgrades controlled, maintainable, and compliant with common cabling and patching practices.

Key Applications:

• Enterprise switch uplinks over singlemode fibre
• Router-to-switch 1GbE backbone links
• Data centre row-to-core 1GbE interconnect
• Server SFP NIC optical connectivity
