D-Link 1000BASE-SX Mini Gigabit Interface Converter (DEM-311GT)
The D-Link DEM-311GT is a high-performance Small Form-factor Pluggable (SFP) transceiver designed to provide Gigabit connectivity over multi-mode fiber using an 850 nm wavelength. It supports data transfer rates up to 1 Gbps for distances up to 550 meters, making it ideal for high-speed LAN applications.
Key Applications
- Expanding Gigabit Ethernet networks over fiber.
- Interconnecting switches and other devices over medium distances.
- Environments requiring high-speed data transfer with reduced electromagnetic interference.
Usage Warnings
- Designed for use with multi-mode fiber cables only.
- Ensure host device compatibility with SFP modules and 1000BASE-SX standard.
- Recommended not to exceed the maximum specified distance (550 meters) for optimal performance.
