DIGITUS DN-81011 — Industrial Gigabit LX SFP, 20 km
1.25 Gbps1310 nm · LCUp to 20 km−40 to +85 °C
The DIGITUS DN-81011 is an industrial Gigabit SFP module for single-mode fibre: 1310 nm over an LC duplex connection on 9/125 µm fibre, up to 20 km, rated from −40 to +85 °C. It is MSA compliant and DIGITUS lists it as universal and Cisco compatible, for industrial switches linking buildings, sites and outdoor cabinets. 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 1310 nm Gigabit module at the far end. It will not run on multimode fibre, and it will not pair with DIGITUS’ single-strand BiDi modules DN-81003 / DN-81004, which also reach 20 km but use one fibre and a simplex connector. It has no DDM. 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
20 km in harsh places
A 1310 nm Gigabit optic rated −40 to +85 °C for single-mode links up to 20 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
We fit the DN-81011 for Gigabit single-mode links that end in unheated or sun-exposed cabinets. Order the far-end module with it. If only one strand is free, ask us for the DIGITUS BiDi pair instead. 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.
