DIGITUS OM3 LC to LC Duplex Fiber Patch Cable, 7 m
OM3 MultimodeLC – LC7 mDuplex · LSZH
The DIGITUS DK-2533-07/3 is a 7 m OM3 multimode duplex fibre patch cable with LC and LC connectors, made for short-reach multimode links between switches, servers, storage and patch panels.
It uses OM3 laser-optimised multimode 50/125 µm fibre in a LSZH jacket of 2 mm, colour-coded aqua so the fibre type is recognisable in the rack. Each cord is single-packed with its own test report.
Before you order: Match the fibre type of your transceivers: this is OM3 multimode for SR/SX optics. Single-mode (LR/LX) optics need an OS2 cord.
What's in the Box
- 1 × fibre optic patch cord, single-packed in a DIGITUS polybag
- Individual test report
What It Means in Practice
- Under IEEE 802.3, OM3 carries 10GBASE-SR up to 300 m and 25GBASE-SR up to 70 m — a patch cord is only a small part of that budget.
- Connectors: LC on both ends — LC (small-form-factor latch connector, used on SFP, SFP+, SFP28 and most duplex QSFP optics).
- Length: at 7 m it reaches between racks or across a server room.
- If the link stays dark, the usual cause is polarity (transmit to transmit): swap the two legs at one end.
- LSZH jacket: low smoke and zero halogen when exposed to fire — the jacket normally required in offices, data rooms and public buildings.
What Will Not Work
- Single-mode optics (10GBASE-LR, 1000BASE-LX, BiDi LR, GPON) — they need OS2 single-mode fibre; a multimode cord will not give a reliable link.
- Ports other than LC — LC does not fit other connector types without a hybrid cord or adapter; check both ends of your link before ordering.
- Single-fibre BiDi optics with a simplex port — they take one fibre; use a simplex cord there.
- RJ45/copper ports — this cable carries light, so both ends need fibre ports or optical transceivers.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
Most fibre problems we see are mismatches, not faulty cables: multimode on a single-mode optic, UPC into an APC socket, or LC ordered for an SC panel. Check the label on your transceiver and the connector on your panel, then pick fibre type, connectors and length to match. For the active side, see our switches with SFP ports.
✓ Buy it if you need a 7 m OM3 LC to LC duplex link for SR/SX optics.
✕ Skip it if your transceivers are single-mode (LR/LX), your ports are not LC.
→ Also consider The same type of cord in a different length or connector combination, or SFP/SFP+ transceivers matching the fibre — tell us your equipment and we will suggest the exact code.
Not sure it fits your setup? Send us the model of your rack, switch or device and we will check compatibility before you order.
