Hot-Pluggable Design
The SFP form factor allows installation and removal while the switch remains powered on, minimizing network downtime during maintenance or upgrades.
- No need to power down equipment
- Quick module replacement
- Standard SFP dimensions
Deployment / Use Cases
The DEM-310GT transceiver is ideal for extending Gigabit Ethernet networks beyond the limitations of copper cabling. Its 0.55 km reach makes it suitable for connecting network segments across different floors, buildings, or campus environments where fiber infrastructure already exists or is being deployed.
Common applications include uplink connections between switches in distributed network topologies, server-to-switch links in data centers requiring electrical isolation, and backbone connections in enterprise networks where distance exceeds 100 meters. The module's compatibility with both fiber types allows network designers to optimize for cost with multi-mode in shorter runs or maximize distance with single-mode for longer spans.
Physical Profile
The transceiver features a compact SFP form factor measuring 2.25" (57.15 mm) in height, 1.19" (30.23 mm) in width, and 0.47" (11.94 mm) in depth. This standardized size ensures proper fit in SFP slots across compatible networking equipment. The module's dimensions allow high-density deployment in switch chassis with multiple SFP ports, maximizing port utilization in rack-mounted environments.

FAQ
What type of fiber connector does the DEM-310GT use?
The DEM-310GT uses an LC duplex connector, which is a small form-factor fiber optic connector commonly used in SFP transceivers. The LC connector provides a secure connection with low insertion loss, making it ideal for high-density network environments where space is at a premium.
What is the maximum distance this transceiver can support?
This transceiver supports a maximum distance of 0.55 kilometers (approximately 0.34 miles) over optical fiber. The actual achievable distance may vary depending on fiber type, quality, and network conditions, but the 0.55 km specification represents the designed reach for reliable Gigabit Ethernet performance.
Does this SFP module work with both multi-mode and single-mode fiber?
Yes, the DEM-310GT is compatible with both multi-mode and single-mode fiber optic cables. This dual compatibility provides deployment flexibility, allowing network administrators to use existing fiber infrastructure or choose the most cost-effective fiber type for their specific distance requirements without needing different transceiver models.
