LevelOne SFP-2504 — 2.5G Single-Mode SFP, 40 km

2.5 Gbps40 km single-mode1310 nmDDM

The LevelOne SFP-2504 is a 2.5 Gbps SFP transceiver for single-mode fibre, reaching up to 40 km at 1310 nm over a duplex LC connection, with digital diagnostics. LevelOne positions it for extended metro and regional 2.5G links, fronthaul and long campus runs. It is built to the SFP MSA, so it is not tied to one switch brand. 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 needs a switch port that supports 2.5G optics. LevelOne does not publish a 1 Gbps mode, so do not plan it for a 1G-only SFP port or expect it to link to a 1G module. Its long reach is for long runs: on a short link, the SFP-2503 (20 km) is the usual choice — tell us the length and we check it. 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

✓ 2.5G links between distant sites
✓ Metro and regional aggregation
✓ Single-mode runs up to 40 km
✓ Telco fronthaul and midhaul
✓ Long campus backbones
✓ Switches with 2.5G SFP ports

Key Features

 
40 km at 2.5G
A 1310 nm single-mode optic that carries 2.5 Gbps up to 40 km, for links between sites.
 
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

Will it work in a 1G SFP port?
LevelOne publishes it as a 2.5 Gbps module and lists no 1 Gbps mode. Both ends of the link and the switch ports must support 2.5G optics. Send us the switch model and we check it.
SFP-2504 or SFP-2503?
Both are 2.5G single-mode at 1310 nm. The SFP-2504 reaches 40 km with a stronger transmitter; the SFP-2503 reaches 20 km. Pick by the real length of the run.
Are fibre patch cords included?
No. You get the SFP-2504 module, a Quick Installation Guide and a Declaration of Conformity. The patch cord for the Duplex LC 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?
LevelOne builds its modules to the SFP MSA and does not code them for one switch brand. Switches that lock out third-party optics may refuse them — send us the model and we check it.
Singular Expert Insight
We suggest the SFP-2504 when a 2.5G link runs well beyond 20 km. For shorter runs the SFP-2503 is the better fit, and for outdoor cabinets the industrial SFP-2603 covers −40 to +85 °C. 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 2.5G over single-mode fibre on runs of 20–40 km.

Skip it if

Your port is 1G-only, the run is short, or the module sits in an unheated cabinet.

Also consider

LevelOne SFP-2503 for runs up to 20 km.
