D-Link DEM-310GT 1000BASE-LX 10KM Single-Mode SFP Transceiver Module
The D-Link DEM-310GT is a high-performance SFP optical transceiver designed for 1000BASE-LX Gigabit Ethernet connectivity over single-mode fiber. It operates at a nominal 1310nm wavelength and supports transmission distances of up to 10km.
The module uses a compact SFP form factor with a Duplex LC connector and is designed for full-duplex Gigabit network connections. Its hot-pluggable design allows installation or replacement without requiring the connected networking equipment to be powered down. :contentReference[oaicite:0]{index=0}
1000BASE-LX Gigabit Ethernet Connectivity
The DEM-310GT supports the IEEE 802.3z 1000BASE-LX standard and provides a 1.25Gbps optical interface for compatible Gigabit Ethernet networking equipment.
It is suitable for connecting switches, network aggregation equipment, and other compatible devices across single-mode fiber infrastructure where extended Gigabit Ethernet reach is required. :contentReference[oaicite:1]{index=1}
10KM Single-Mode Fiber Transmission
The transceiver is designed for 9/125μm single-mode fiber and supports distances of up to 10km. This makes it suitable for longer Gigabit Ethernet links across enterprise, campus, and network infrastructure environments. :contentReference[oaicite:2]{index=2}
1310nm Optical Transmission
The DEM-310GT operates at 1310nm, providing optical transmission over compatible single-mode fiber. The D-Link datasheet specifies a 16dB link budget for this transceiver revision. :contentReference[oaicite:3]{index=3}
Duplex LC SFP Interface
The module features a Duplex LC connector for separate transmit and receive optical paths. Its standard SFP form factor enables installation in compatible SFP ports on networking equipment.
Hot-Pluggable Design
The DEM-310GT is hot pluggable, allowing the transceiver to be installed or replaced while the compatible system remains powered. This can simplify maintenance and reduce network downtime during module replacement. :contentReference[oaicite:4]{index=4}
