D-Link DEM-310GT 1000Base-LX SFP Transceiver 10km Single-Mode Module
The D-Link DEM-310GT is a high-performance 1310nm single-mode SFP transceiver designed for enterprise and service provider networks. Supporting full-duplex Gigabit speeds up to 1.25Gbps over distances up to 10km on 9/125 micron single-mode fiber, this hot-pluggable module delivers reliable, high-speed connectivity for switch cascading, data centre links, and network expansion applications.
Key Features
-
10km Transmission Distance: Delivers reliable Gigabit Ethernet connectivity over single-mode fiber up to 10 kilometres
-
Hot-Pluggable Design: Swap modules without powering down your switch, minimising network downtime during maintenance
-
IEEE 802.3z Compliant: Full 1000Base-LX standard compliance ensures broad compatibility with enterprise network equipment
-
Duplex LC Connector: Industry-standard connector type for quick, secure fiber cable connections
-
Metal Housing: Reduces electromagnetic interference and increases durability in demanding environments
-
MSA and RoHS Compliant: Meets Multi-Source Agreement standards and environmental regulations
Enterprise-Grade Performance
The DEM-310GT operates at a 1310nm wavelength and is optimised for single-mode fiber deployments. With support for full-duplex Gigabit transmission, this SFP module is ideal for distributed multi-processing, switch cascading, high-speed file transfers, and channel extension applications across campus and metropolitan networks.
Hot-Swap Capability
All D-Link SFP transceivers feature hot-pluggable capability, allowing network administrators to install or remove modules from an SFP slot while the system is powered on. This facilitates seamless network maintenance, module upgrades, and troubleshooting without interrupting network operations or requiring system reboots.
Versatile Applications
The DEM-310GT is perfectly suited for:
- Gigabit Ethernet switch uplinks and cascading
- Data centre and storage area network (SAN) connections
- Enterprise LAN backbone links
- ISP and service provider infrastructure
- Fiber channel and high-speed I/O applications
Small Form-Factor Advantages
The SFP (Small Form-Factor Pluggable) design offers significant advantages over larger form factors including lower power consumption, reduced physical footprint, and higher port density. This makes the DEM-310GT an economical and space-efficient solution for growing network infrastructures.
