DIGITUS DN-81204 — 10G BiDi SFP+, 10 km

10 GbpsOne fibre strandTX 1270 / RX 1330Up to 10 km

The DIGITUS DN-81204 is a 10 Gbit bidirectional (BiDi) SFP+ module that runs a full 10G link over a single single-mode fibre strand, up to 10 km. It transmits at 1270 nm and receives at 1330 nm through a simplex LC connector, with digital diagnostics, and is built to the MSA standard for switches that accept third-party optics. In practice, bidirectional optics are used where fibre is scarce — a leased dark-fibre strand, a full duct or an old building link. Before you order, confirm which end of the strand gets which module type and that the fibre is single-mode all the way.

Compatibility — check before buying:
This is a BiDi module, not a two-fibre LR optic: the far end needs a module that transmits at 1330 nm and receives at 1270 nm — two DN-81204 will not link. The connector is simplex LC. DIGITUS does not name the partner part in the datasheet, so ask us and we match it. The DN-81206 has the same wavelengths but reaches 40 km. 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

✓ 10G links over a single fibre strand
✓ Leased fibre charged per strand
✓ Links between buildings up to 10 km
✓ Doubling capacity on existing fibre
✓ Switches that accept MSA optics
✓ Full ducts with no spare fibre

Key Features

 
10G on one fibre
Both directions share one single-mode strand up to 10 km, so an existing fibre pair can carry two 10G links.
 
One strand instead of two
A bidirectional optic sends and receives on different wavelengths over a single single-mode strand, which halves the fibre you need. The price of that is pairing: the two ends must be opposite types.
 
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

Do I need two of these for a link?
No. The other end needs the opposite type, transmitting at 1330 nm and receiving at 1270 nm. Tell us the switch at the far end and we match the module.
What is the difference to DN-81206?
Same 1270/1330 nm plan; the DN-81206 reaches up to 40 km, the DN-81204 up to 10 km.
Are fibre patch cords included?
No. You get 1 module. The patch cord for the LC simplex connector, a matching module for the far end of the link and a fibre cleaning tool are bought separately. Tell us the distance and the fibre type and we quote the right cord.
Will it work in a switch from another brand?
DIGITUS lists compatibility with many brands but states no vendor-specific coding, so switches that lock out third-party optics may reject it — send us the model and we check it.
Singular Expert Insight
We suggest the DN-81204 where a 10G link has to run over one single-mode strand. Order it together with the opposite-wavelength module so the link comes up on day one, and check that both switches accept third-party optics. 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 10G over one single-mode strand up to 10 km, with the opposite BiDi type at the far end.

Skip it if

You have two strands free (a standard LR pair is simpler), you need more than 10 km, or your switch locks out third-party optics.

Also consider

DIGITUS DN-81206 for 40 km BiDi links.
