DIGITUS DN-81001 — 1G LX Single-Mode SFP, 20 km
1 Gbps1310 nm · LCUp to 20 kmMSA / Cisco coded
The DIGITUS DN-81001 is a Gigabit SFP transceiver for single-mode fibre: 1000BASE-LX at 1310 nm over an LC duplex connection (two fibres), reaching up to 20 km on 9/125 µm fibre. It is the universal, MSA-compliant DIGITUS LX module, and DIGITUS lists a long range of switch brands it works with. 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:
It is a duplex module that uses two fibres. Do not confuse it with the DN-81003, which has an almost identical title but is a single-fibre BiDi module. It needs single-mode fibre and an LX module at the far end, and it will not come up in a 10G-only port. For HP / Aruba switches choose DN-81001-01, for Cisco-coded ports DN-81001-02. 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 buildings
✓ Campus backbones up to 20 km
✓ Single-mode (OS1/OS2) fibre
✓ Uplinks to a remote cabinet
✓ Spare optics at a low cost
✓ Replacing a failed 1G LX module
Key Features
20 km on single-mode
A 1310 nm LX optic with a 20 km rating, enough for most campus and inter-building links.
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.
Hot-swappable
Modules and cables 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 or pull tab 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 part, the cable and any spares in one go and the link works on day one.

Frequently Asked Questions
Singular Expert Insight
The DN-81001 is the Gigabit single-mode optic we reach for on switches that accept standard modules. Order two — one for each end — and single-mode LC duplex cords. If only one strand is free, the DN-81003 / DN-81004 BiDi pair is the answer. 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 1G single-mode link up to 20 km over two fibres on a switch that accepts MSA optics.
Skip it if
Only one fibre strand is free, your fibre is multimode, or your switch only takes HP / Aruba-coded optics.
