SFP Network Adapter Digitus DN-3026 USB 3.0 Gigabit

The Digitus DN-3026 USB 3.0 Gigabit SFP Network Adapter converts a USB 3.0 port into a high-speed SFP network interface. It accepts standard SFP transceivers (additional SFP module required) to connect directly to fiber optic networks or other SFP-based links. The adapter is compact and bus-powered via USB 3.0, making it suitable for both mobile and stationary use. It supports up to 1000 Mbps data transfer and is compatible with Windows, macOS, Chrome OS and other USB 3.0 capable systems.

Advantages

The adapter uses a Realtek RTL8153 chipset and supports Gigabit Ethernet over SFP with advanced energy-saving features (IEEE802.3az). It offers Layer 2 capabilities such as VLAN tagging (IEEE 802.1Q) and priority encoding (IEEE 802.1p), IPMI pass-through, Wake-on-LAN, PXE and iSCSI boot, and hardware checksum offload for IPv4/IPv6 (NDIS5/6). The device is plug-and-play with a virtual CD driver included, requires no external power supply, and provides automatic cable and polarity correction plus integrated transmit/receive buffering for stable throughput.

Suitable for

• Extending laptops or desktops without SFP ports to fiber networks
• Temporary or mobile connections to SFP-based infrastructures
• Network troubleshooting and monitoring in data centers
• Environments requiring wired Gigabit connectivity where Wi‑Fi is unsuitable

How to use

Insert a compatible SFP transceiver into the adapter's SFP port, then connect the adapter to a computer's USB 3.0 port. The adapter is bus-powered and requires no external power supply. On first use the included virtual CD image provides drivers if the host does not automatically recognize the device; otherwise the adapter functions as plug-and-play. Configure network settings on the host operating system and, if required, set VLAN or priority options via system network tools or drivers.

Recommendations

Use USB 3.0 ports for full Gigabit throughput and choose an SFP transceiver that matches the target fiber type and distance. Avoid operating the adapter outside the specified temperature and humidity ranges and ensure the host system provides sufficient power over USB. For network boot or IPMI pass-through features, verify BIOS/firmware and driver support on the host system.
