LevelOne GVT-2011 — Gigabit Media Converter Switch, 1 × RJ45 + 2 × SFP, Redundant Fibre Mode
2 × SFP + 1 × RJ45GigabitSwitch or redundant modeSFPs not included
The LevelOne GVT-2011 is a Gigabit media converter switch that joins a 10/100/1000Base-T RJ45 copper port to two SFP slots, so an Ethernet link can run over fibre where copper stops at 100 metres. It suits fibre links that need a backup path, or a small fibre junction where two fibre runs and one copper device meet.
A DIP switch selects how the two SFP ports behave. In switch mode (default) all three ports switch traffic like a small 3-port Gigabit switch. In redundant mode, SFP port F1 is the main link and F2 takes over automatically if F1 fails — LevelOne’s manual states within 10 ms. Both SFP slots take standard 1000Base-SX/LX modules, sold separately.
Before you order: no SFP modules are included. Fit Gigabit 1000Base-SX (multimode) or 1000Base-LX (single-mode) SFPs that match the far ends; for redundant mode both fibre paths must lead back to the same network.
What's in the Box
- GVT-2011 media converter switch
- Power adapter (5 V / 2 A, external)
- Quick installation guide
- SFP modules and fibre patch cords are not included
What It Means in Practice
- Redundant mode gives a fibre link a second, independent path — if one fibre is cut or a module fails, traffic moves to the other.
- Switch mode lets you daisy-chain: one fibre in, one fibre out to the next building, and a local device on the RJ45 port.
- Optics are your choice per port, so one side can be multimode and the other single-mode.
- VLAN tags and multicast pass through, with packets up to 9,000 bytes.
What Will Not Work
- Without SFP modules — none is supplied.
- 100Base-FX or 10G SFP+ modules: the slots are 1000Base-SX/LX.
- Management or monitoring: no web interface or SNMP.
- PoE in or out on the RJ45 port.
Key Features
Two SFP slots
Two 1000Base-SX/LX SFP cages plus one 10/100/1000 RJ45 port in one compact box.
Redundant fibre mode
DIP switch selects redundant mode: F2 backs up F1 automatically, within 10 ms per LevelOne’s manual.
3-port switch mode
Default mode switches traffic between all three ports — useful for daisy-chained fibre runs.
Store-and-forward
IEEE 802.3x flow control, back pressure, VLAN tag and multicast pass-through, 9,000-byte packets.

Frequently Asked Questions
How does redundant mode work?
Set the DIP switch to ON. F1 carries traffic; if its link is lost, F2 takes over automatically. Both fibres should connect back to the same network, typically to two ports or two switches at the core.
Can I mix multimode and single-mode?
Yes — each SFP slot takes its own module, so one link can be multimode (1000Base-SX) and the other single-mode (1000Base-LX).
Does it need configuring?
No software: choose the mode with the DIP switch, fit the SFPs and connect.
Singular Expert Insight · Buyer's Guide
The GVT-2011 is the inexpensive way to add a backup fibre path to a remote device without buying a managed switch. Remember the two SFPs on top of the price. If you need VLAN control, monitoring or more ports at the remote site, a small managed switch with SFP slots is the better buy — see our
network switches.
✓ Buy it if you want a Gigabit fibre link with automatic failover, or a simple 2-fibre + 1-copper junction.
✕ Skip it if you need management, PoE, or more than one copper port.
→ Also consider LevelOne GVT-2010 (single SFP, PoE-powered) or GVM-1220 (managed, SC single-mode).
