LevelOne SFP-2501 — 2.5G Multimode SFP, 300 m
2.5 Gbps850 nmOM3 / OM4Up to 300 m
The LevelOne SFP-2501 is a 2.5 Gbps SFP transceiver for OM3 and OM4 multimode fibre, reaching up to 300 m at 850 nm over a duplex LC connection, with digital diagnostics. It suits 2.5G access uplinks and backbones inside a building, where switches with 2.5G SFP ports feed multi-gig access points and workstations. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry OM3 or OM4 fibre, and the module plus a short patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
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. LevelOne publishes the 300 m for OM3/OM4 fibre; on older OM1/OM2 fibre the reach is shorter. For single-mode runs, the SFP-2503 is the 2.5G option. 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 uplinks inside one building
✓ Switches with 2.5G SFP ports
✓ Multi-gig access-layer backbones
✓ OM3 / OM4 multimode runs
✓ Fronthaul inside a site
✓ Replacing a failed 2.5G module
Key Features
2.5G on multimode
Carries 2.5 Gbps over OM3 or OM4 multimode fibre up to 300 m, the step between Gigabit and 10G for access uplinks.
Multimode fibre, short reach
Built for the short runs inside a building or data room over OM-grade multimode fibre. Reach depends on the fibre grade — check what is actually in your walls before you plan a link.
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
Singular Expert Insight
We suggest the SFP-2501 for 2.5G links inside a building on OM3 or OM4 fibre. Check that both switches take 2.5G optics; for runs between buildings, the single-mode SFP-2503 reaches 20 km. 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 OM3/OM4 multimode up to 300 m between 2.5G SFP ports.
Skip it if
Your port is 1G-only, your fibre is single-mode, or the link must run at 10G.
Also consider
