D-Link DEM-311GT 1000Base-SX Multi-Mode Fibre SFP Transceiver 550m

    Description

    D-Link DEM-311GT 1000Base-SX Multi-Mode Fibre SFP Transceiver 550m

    The D-Link DEM-311GT is a high-performance 850nm multi-mode SFP transceiver designed for expanding Gigabit Ethernet networks over fibre optic cable. Supporting full duplex Gigabit speeds and distances up to 550m on 50µm fibre or 220m on 62.5µm fibre, this hot-pluggable module is ideal for enterprise LAN, data centre networks, and inter-building connectivity. The DEM-311GT is MSA compliant and features a robust metal housing to reduce EMI and increase durability.

    Key Features

    • High-speed connectivity: 1.25 Gbps data links for fast, reliable network performance
    • Extended reach: Up to 550m on 50/125µm multi-mode fibre, 220m on 62.5/125µm fibre
    • Hot-pluggable design: Install or remove while the switch is powered on for easy maintenance and minimal downtime
    • MSA compliant: Industry-standard SFP form factor ensures broad compatibility with D-Link and multi-vendor equipment
    • Durable metal housing: Reduces electromagnetic interference (EMI) and enhances long-term reliability
    • RoHS compliant: Environmentally responsible and certified for laser safety

    850nm Multi-Mode Performance

    The DEM-311GT uses a VCSEL laser at 850nm wavelength, optimised for short to medium-range connections over multi-mode fibre. It delivers consistent, high-quality Gigabit Ethernet performance for applications such as ISP links, enterprise networks, data centres, and campus fibre backbones. With a duplex LC connector, it integrates seamlessly into your existing fibre infrastructure.

    Universal Compatibility

    This SFP transceiver is designed to work with D-Link Gigabit and Fast Ethernet switches with SFP/mini-GBIC slots, and is also compatible with other MSA-compliant networking devices. It conforms to IEEE 802.3z 1000Base-SX standards, ensuring plug-and-play operation across a wide range of network equipment including switches, routers, and network interface cards.

    Applications

    • Enterprise LAN and SAN networks
    • Data centre LAN and SAN interconnects
    • Internet Service Provider (ISP) Gigabit Ethernet links
    • Building-to-building fibre connections
    • Campus network backbones
