LevelOne SFP-3411 — Gigabit Single-Mode SFP, 40 km
1 Gbps1310 nmSingle-modeUp to 40 km
The LevelOne SFP-3411 is a Gigabit SFP transceiver for 9/125 µm single-mode fibre, reaching up to 40 km at 1310 nm over a duplex LC connection, with digital diagnostics. LevelOne positions it for metro Gigabit aggregation, telco distribution and ISP middle-mile links — routes that are longer than a standard 10 km LX module can cover. In practice, single-mode optics are the choice when a link leaves the building or runs several hundred metres: the OS2 fibre used by carriers and campus backbones carries the signal for kilometres with little loss. Before you order, confirm the fibre is single-mode at both ends and note the length and the number of patch panels on the way.
Compatibility — check before buying:
Use the same type at both ends: it runs at 1310 nm and will not link to a 1550 nm ZX module such as the GVT-0302. For runs of only a few kilometres, the 10 km GVT-0301 is the usual choice — tell us the length and we check it. It is a 1G module and needs single-mode fibre. Keep the dust cap on until you connect the fibre, and clean both connector ends before every mating — dirt is the most common cause of a link that will not come up. Not sure? Send us your device model and the cable run and we check it before you order.
Best For
✓ Gigabit links between distant sites
✓ Metro and ISP middle-mile links
✓ Single-mode runs of 10–40 km
✓ Telco distribution links
✓ Rural and industrial-park fibre
✓ Switches with 1G SFP ports
Key Features
40 km at Gigabit
A 1310 nm optic that carries Gigabit Ethernet up to 40 km over single-mode fibre, for routes beyond the reach of an LX module.
Single-mode fibre, long reach
Built for single-mode (OS1/OS2) fibre, the type used between buildings, floors and sites. It will not run over the orange or aqua multimode fibre found in many racks — the fibre type has to match at both ends.
Monitoring you can read
Digital diagnostics (DDM) let the host report temperature, laser power and received light, so a dirty connector or a failing link shows up before users call.
Hot-swappable
Modules plug into a live port without shutting the switch down, so a link can be added or replaced during working hours. Seat it until it clicks and use the latch to remove it.

Frequently Asked Questions
Singular Expert Insight
We suggest the SFP-3411 when a Gigabit single-mode route runs past 10 km but stays within 40 km. Order both ends together as the same model, and send us the route details if you want us to check the link budget. Every order is backed by Singular’s local support in Cyprus — if a link will not come up, send us the port status and we help you find out whether it is the module, the cable or the configuration. Browse all transceivers and DAC cables or the switches they plug into.
Buyer’s Guide
Buy it if
You need a Gigabit single-mode link of 10–40 km on SFP ports that accept MSA optics.
Skip it if
The run is short (GVT-0301), over 40 km (GVT-0302), or the fibre is multimode.
Also consider
LevelOne GVT-0302 for 1550 nm runs up to 80 km.
