D-Link 1-port Mini-GBIC SFP to 1000BaseLX, 10km for all

The D-Link DEM-310GT is a compact 1000Base-LX mini-GBIC (SFP) network transceiver module designed for Gigabit fiber connections. Housed in a stainless-steel metal case, this transceiver supports full-duplex Gigabit speeds over multimode and singlemode fiber and is suitable for integration into switches and other compatible network equipment. The module is hot-pluggable and comes with a standard 3-year product warranty.

Advantages

The DEM-310GT offers a balance of performance and affordability, providing reliable Gigabit connectivity in a small SFP form factor. Its metal housing reduces electromagnetic interference and increases mechanical durability. Support for both multimode and singlemode fibers makes the module flexible for different link distances, while hot-pluggable operation allows easy installation and replacement without powering down equipment.

Suitable for

• Upgrading switches and routers to Gigabit fiber links
• Short- and medium-distance fiber connections in LANs
• Data center patching and fiber uplinks

How to use

Insert the DEM-310GT SFP transceiver into a compatible SFP port on your switch, router, or media converter until it clicks into place. Connect the appropriate fiber cable (multimode or singlemode) to the transceiver's port and secure the connection. Configure the connected network device for 1000Base-LX operation if manual configuration is required. The module supports hot-plugging, so it can be installed or replaced while the host device is powered on.

Recommendations

Use fiber cables and connectors that match the specified fiber type (62.5 µm, 50 µm multimode or 9 µm singlemode) and follow proper fiber handling procedures. For links approaching the maximum supported distances, verify link budget and connector losses. Store the module in an anti-static environment when not in use and handle the optical ports carefully to avoid contamination.
