D-Link 1-poorts mini-GBIC SFP naar 1000BaseSX, 550 m voor alle

The D-Link DEM-311GT is an SFP/mini-GBIC multimode fiber transceiver designed for Gigabit Ethernet links. It operates at 850 nm and supports full-duplex Gigabit speeds over multimode fiber, providing reach up to 220 m on 62.5 µm fiber and up to 550 m on 50 µm fiber. The transceiver has a metal housing for improved durability and EMI reduction, and it supports hot-pluggable operation.

Advantages

The DEM-311GT combines compact SFP form factor with high performance and cost-effective design. Metal casing enhances mechanical robustness and minimizes electromagnetic interference. Hot-pluggable capability simplifies installation and maintenance, and the product is covered by a standard two-year warranty with access to technical support.

Key specifications

How to use

Insert the DEM-311GT SFP transceiver into a compatible SFP slot on a switch or router while the device is powered on or off, as it supports hot-pluggable operation. Connect the appropriate multimode fiber patch cord (62.5 µm or 50 µm) to the transceiver and secure connections at both ends. Verify link status on the network device and configure the port for Gigabit full-duplex operation if required by the switch or router settings.

Rekomendations

Use the DEM-311GT with compatible D-Link or industry-standard SFP ports and select the correct multimode fiber type to achieve the specified reach. For reliable performance, follow manufacturer guidelines for handling fiber connectors and observe ESD precautions during installation.
