LevelOne GEU-0521 5-Port Gigabit Switch with SFP Fiber Uplink

4 × RJ-45 + 1 × SFPCopper-to-Fiber10GBps FabricFanless & Compact

The LevelOne GEU-0521 is a compact 5-port Gigabit unmanaged switch with 4 x 10/100/1000BASE-T RJ-45 ports plus 1 x 1000BASE-X SFP slot, designed to bridge copper and fibre networks in small offices, workgroups and edge locations. The SFP uplink lets you extend your network over fibre to remote rooms, buildings or wiring closets, while non-blocking wire-speed switching keeps large transfers and IP surveillance backhaul running smoothly.

Identified by part number GEU-0521, the switch is fanless and silent in a small black housing, powered by an included external adapter, and can sit on a desk or mount to a wall. Typically in stock with fast delivery across Cyprus.

Good to know before you buy

This is an unmanaged switch — it works instantly with no setup, but offers no VLANs, QoS or web management. The SFP module is not included; add a 1000BASE-X SFP transceiver to use the fibre uplink. It does not supply PoE, and runs from an included external 5V power adapter. The 5 ports are shared as 4 RJ-45 plus 1 SFP (5 concurrent). For full Gigabit copper speeds use Cat 5e or Cat 6 cabling.

Best For

✓Extending a network over fibre to another room or building

✓Small offices and workgroups needing a copper-to-fibre bridge

✓IP surveillance backhaul and NAS/server connections

✓Wiring closets and space-limited spots needing a compact switch

✓Silent, fanless operation in offices and living spaces

✓Plug-and-play use with no configuration required

Key Features

Hybrid Copper + Fibre

4 x 10/100/1000BASE-T RJ-45 ports plus 1 x 1000BASE-X SFP slot let you mix copper devices with a fibre uplink for flexible, long-distance extension.

Non-Blocking Wire Speed

A 10GBps switching fabric with store-and-forward forwarding moves traffic across all ports at full Gigabit speed without bottlenecks.

Fanless & Compact

At just 96 x 112 x 30 mm and 0.38 kg, the silent fanless housing fits on a desk, shelf or wall in tight spaces.

9K Jumbo Frames

9KB jumbo frame support boosts efficiency for high-bandwidth tasks like backups, IP surveillance and multimedia, backed by IEEE 802.3x flow control.

Frequently Asked Questions

Is an SFP module included with the GEU-0521?

No. The SFP slot is empty — you need to add a compatible 1000BASE-X SFP transceiver to use the fibre uplink. The four RJ-45 copper ports work out of the box.

Does the GEU-0521 need any configuration?

No. It is an unmanaged plug-and-play switch. Connect your Ethernet (and optional fibre) cables, power it on, and it begins forwarding traffic immediately.

Does the GEU-0521 supply PoE power?

No. This model does not provide Power over Ethernet. Devices such as IP cameras or access points will need their own power source or a separate PoE switch.

What is the SFP port useful for?

The 1000BASE-X SFP uplink lets you connect over fibre, extending your network far beyond copper distance limits — ideal for linking buildings, distant rooms or wiring closets.

Singular Expert Insight

What sets the GEU-0521 apart from a plain 5-port switch is the SFP fibre uplink — a compact, affordable way to bridge copper and fibre without stepping up to a managed switch. It is ideal when you need to reach a device or building beyond the 100m copper limit. Remember the SFP transceiver is bought separately. If you do not need fibre, a standard copper-only switch is cheaper; if you need more ports or fibre with management, explore our wider network switches range, and pair with an access point to extend Wi-Fi. For copper-to-fibre at the edge, this is a smart, low-cost choice.

Buyer’s Guide

Buy it if

You need a compact, silent switch that bridges copper and fibre via SFP, want zero configuration, and value a tiny fanless desktop or wall-mount design.

Skip it if

You do not need fibre (a copper-only switch is cheaper), need PoE for cameras/APs, or require more than five ports or managed VLAN/QoS features.

Also consider

A plain 5-port Gigabit switch if you have no fibre, a higher port-count model with SFP for larger sites, or a managed switch if you need VLANs and traffic control.
