LevelOne SFP-3211 — Gigabit LX SFP, Single-Mode 10 km
1 Gbps1000BASE-LX1310 nm · LCUp to 10 km
The LevelOne SFP-3211 is a Gigabit SFP transceiver for single-mode fibre: 1000BASE-LX at 1310 nm over a duplex LC connection, up to 10 km on 9/125 µm fibre. It is the commercial-temperature LX module for links between buildings on LevelOne switches and media converters and on other MSA-compliant SFP ports. In practice, single-mode optics are the choice when a link leaves the building or runs more than a few hundred metres: the 9/125 µm 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:
It needs two single-mode fibres and a 1000BASE-LX (1310 nm) module at the far end. It will not link to a single-strand BiDi module such as the SFP-9221, or run on multimode fibre (for that, see SFP-3001). It is a 1G optic, not for 10G-only SFP+ ports. Some LevelOne listings and file names mention 20 km; LevelOne’s datasheet for this model gives 10 km, which is what we publish. 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 switch model and the cable run and we check it before you order.

Key Features
Gigabit between buildings
A 1310 nm LX optic that carries Gigabit Ethernet over single-mode fibre up to 10 km.
Single-mode fibre, long reach
Built for single-mode (9/125 µm) 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.
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.
Plan both ends together
A link only comes up when both ends use the same standard, speed and media. Order the far-end module, the patch cords and any spares in one go and the link works on day one.

Frequently Asked Questions
Singular Expert Insight
The SFP-3211 is the Gigabit single-mode optic we fit for links between buildings on LevelOne and other open switches. Order the far-end LX module with it and use single-mode duplex LC cords. If only one strand is free, the BiDi pair SFP-9221 / SFP-9231 does the job on a single fibre. 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 or the switches they plug into.
Buyer’s Guide
Buy it if
You need a 1G link over duplex single-mode fibre up to 10 km in an indoor rack.
Skip it if
Your fibre is multimode, only one strand is free, or the module sits in an outdoor cabinet.
