Digitus OM3 Multimode Fibre Patch Cable — LC/PC to ST/PC, Duplex, 3 m
OM3 50/125 µmLC – ST PC3 m DuplexLSOH Aqua
The Digitus DK-2531-03/3 is a 3 m duplex OM3 multimode fibre optic patch cable with LC/PC on one end and ST/PC on the other, built on 50/125 µm fibre in a LSOH aqua jacket, 2.0 mm in diameter. It is made for short-reach links in server rooms and buildings with 850 nm SR/SX multimode transceivers on 50/125 µm fibre.
LC is the small-form connector used by SFP/SFP+ transceivers and most current switch and media-converter fibre ports. ST is the round bayonet (twist-lock) connector found on older patch panels and legacy equipment. So this cable bridges an LC port on one side and an ST port on the other — check both ends before ordering.
Before you order: This is OM3 50/125 µm multimode. Use it with multimode optics (SR/SX, 850 nm) and match the fibre type already installed — do not mix it with singlemode or 62.5/125 µm OM1 fibre.
What's in the Box
- 1 × Digitus duplex fibre optic patch cable, LC/PC – ST/PC, 3 m
- Individual test report (measurement protocol) for the cable
- Supplied in a polybag
- Transceivers, couplers and cleaning tools are not included
What It Means in Practice
- Duplex means two fibres: one transmits, one receives. If the link does not come up, transmit and receive are usually crossed — swap the two connectors at one end (A↔B) or use a coupler with the correct polarity.
- 3 m is the end-to-end length. Measure the route including slack in cable managers and trays before ordering — fibre should never be pulled tight or kinked.
- On OM3, 10GBASE-SR is specified up to 300 m, so a short patch cord like this never limits the link.
What Will Not Work
- It will not work with singlemode or 62.5/125 µm OM1 fibre or with singlemode optics.
- It does not mate correctly with APC (green, angled) ports or couplers.
- It does not plug into SC, MPO ports. If one end of your link is different, tell us the ports and we will match the right cable.
- It is an indoor patch cord, not an outdoor or direct-burial cable.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
Most fibre faults we see come from three mismatches: singlemode versus multimode, UPC versus APC, and the wrong connector at one end. This Digitus cord is OM3, PC, LC to ST — confirm those three on both devices and it will simply work. For the equipment side, see our network switches.
✓ Buy it if your link is OM3 multimode, both ports are LC and ST with PC polish, and 3 m covers the route with a little slack.
✕ Skip it if either end uses a different connector or polish, your transceivers are singlemode (LX/LR), or you need an outdoor-rated cable.
→ Also consider the same cable in another length, or a coupler/patch panel if you are extending an existing run.
