D-Link DEM-310GT 1-Port 1000BASE-LX Single-Mode SFP Fiber Transceiver

The D-Link DEM-310GT is a high-performance Gigabit SFP (Small Form-factor Pluggable) transceiver designed to provide 1000BASE-LX connectivity over single-mode fiber optic cable. Operating at a 1310 nm wavelength and supporting transmission distances of up to 10 km, it is suitable for long-distance Gigabit Ethernet network connections between switches, servers, routers, and other compatible network equipment. The DEM-310GT features a duplex LC connector, supports full-duplex Gigabit operation, and is hot-pluggable, allowing it to be installed or replaced without powering down compatible equipment.

Product Features

1000BASE-LX Gigabit Ethernet

The DEM-310GT supports the IEEE 802.3z 1000BASE-LX standard, providing Gigabit Ethernet connectivity over single-mode fiber for high-speed network links.

Single-Mode Fiber Support

The transceiver is designed for 9 µm single-mode fiber, making it suitable for longer-distance fiber optic network deployments compared with typical multimode Gigabit transceivers.

Up to 10 km Transmission Distance

The DEM-310GT supports fiber transmission distances of up to 10 kilometres, making it suitable for connecting network infrastructure across buildings, campuses, and other locations where copper Ethernet cannot provide the required distance.

1310 nm Wavelength

The transceiver operates at a 1310 nm optical wavelength, which is specified for its 1000BASE-LX single-mode fiber interface.

Duplex LC Connector

The DEM-310GT uses a duplex LC fiber connector, providing separate transmit and receive paths for the fiber connection.

Full-Duplex Operation

The transceiver supports full-duplex Gigabit Ethernet, allowing simultaneous transmission and reception of data over the fiber link.

Hot-Pluggable Design

The DEM-310GT is hot-pluggable, allowing it to be inserted or removed from compatible SFP-equipped network devices without requiring the entire system to be powered down.

MSA Compliant

The transceiver is MSA compliant, supporting compatibility with equipment designed to accept compatible industry-standard SFP modules. Compatibility should still be confirmed with the specific network device before installation.

Metal Housing

The transceiver features a metal housing designed to reduce electromagnetic interference (EMI) and improve durability.

802.3x Flow Control

The DEM-310GT supports IEEE 802.3x flow control, helping manage data transmission between compatible network devices.
