D-Link DEM-310GT 1-Port SFP LX SM Fiber Transceiver: The Gold Standard for Long-Distance Gigabit Expansion
Standard copper network lines hit a strict performance wall past 100 meters, forcing enterprise environments to seek advanced alternatives for multi-building connectivity. The D-Link DEM-310GT 1-Port SFP LX SM Fiber Transceiver provides an industrial-grade, small form-factor pluggable (SFP) optical module engineered explicitly to break through these physical limits. By translating electrical network data into 1000BASE-LX laser signals, this high-performance transceiver delivers reliable, lightning-fast Gigabit transmission across vast distances with zero data latency.
Why Choose the D-Link DEM-310GT SFP Transceiver
The D-Link DEM-310GT is engineered for high-density environments where structural reliability, cross-brand compatibility, and extended range are required to maintain business continuity.
Blazing-Fast Gigabit Fiber Connectivity
The transceiver module slots directly into standard SFP ports on active switches, routers, and firewalls to provide full 1000Mbps Gigabit throughput. Running in full-duplex operation, it delivers a high-capacity, unhindered transmission pipeline optimized for demanding enterprise tasks—such as localized server data synchronization, real-time multimedia workflows, and main corporate network links.
Extended 10-Kilometer Single-Mode Reach
Standard short-range multi-mode fiber modules suffer from severe signal attenuation over medium distances. The DEM-310GT bypasses this restriction by using a high-efficiency 1310nm optical wavelength tuned precisely for 9/125µm single-mode fiber optic (SMF) cables. This focused light beam architecture safely carries data payloads across distances up to 10 kilometers (6.2 miles), making it a perfect tool for expansive commercial office parks and campus networks.
Toolless Hot-Pluggable Architecture
Network down-time can severely impact company productivity. D-Link eliminates installation friction by building the DEM-310GT with a fully hot-pluggable design. Network administrators can easily insert or remove the transceiver from any active MSA-compliant SFP slot without rebooting the core host switch or disrupting running network operations.
Industrial Build Quality and Performance Features
Operating a large enterprise network core requires equipment that resists mechanical stress and environmental changes. The D-Link DEM-310GT is physically built for maximum operational stability.
- Duplex LC Optical Interface: Features a secure, industry-standard duplex LC connector layout that locks optical patch cords rigidly into place, preventing accidental loose seating faults.
- Sturdy Metal Chassis Enclosure: Housed in a heavy-duty, completely metallic casing that provides superior defense against structural damage, drops physical electromagnetic interference (EMI), and increases thermal dissipation efficiency.
- Multi-Mode Fiber Backward Compatibility: While optimized primarily for 10km single-mode runs, the transceiver’s flexible optics can also step down to interface with legacy multi-mode fiber (MMF) lines across short distances up to 550 meters.
Does the D-Link DEM-310GT require any software configuration?
No. The D-Link DEM-310GT functions as a hardware-level optical interface module. It features true plug-and-play capability, requiring zero driver downloads, software initialization steps, or administrative registration steps—you simply slide the transceiver into place to enable immediate fiber routing.
Can I plug a single-mode fiber line into one side and a multi-mode into the other?
No. To establish a secure connection, both the local and remote transceiver links must be configured with matching optical profiles. Ensure that both ends are connected over the same identical category of fiber optic cabling to avoid immediate signal scattering and link dropouts.
