EFB-Elektronik OM4 Multimode Fiber Patch Cable, LC to LC, Duplex, 10 m

OM4 · 50/125 µmLC ↔ LCDuplex10 m

The EFB-Elektronik O0319.10 is a 10 m duplex OM4 multimode fibre patch cable with LC connectors on both ends, made for short-reach 850 nm links between switches, servers, storage and patch panels.

The cable uses an LSZH jacket with a 2.0 mm outer diameter in heather violet, the usual colour for OM4, so it is easy to tell apart in a busy rack.

Before you order: OM4 multimode works with 850 nm short-reach (SR/SX) multimode optics only. Singlemode LR/LX transceivers will not work on this cable. Check that both ports are LC.

What's in the Box

  • 1 × EFB-Elektronik OM4 duplex fibre patch cable, 10 m, LC – LC
  • Transceivers, couplers and patch panels are not included

What It Means in Practice

  • Two fibres in one cable: one transmits, one receives — the normal setup for SFP, SFP+, SFP28 and most media converters.
  • At 10 m it reaches between neighbouring racks or across a server room; for building backbones use installation cable and patch panels instead.
  • OM4 is laser-optimised 50/125 µm multimode for 850 nm SR optics (10GBASE-SR, 25GBASE-SR, 8/16/32G FC SW).
  • Keep the connectors covered until the moment of connection and clean the end-faces if a link shows high loss — dirt is the most common cause.

What Will Not Work

  • Singlemode LR/LX/ER transceivers (1310/1550 nm) — they need OS2 singlemode cable.
  • Ports of another connector type (SC, ST, MPO/MTP, E2000) without the right hybrid cable or adapter.
  • Permanent in-wall or outdoor installation — this is a patch cable for racks, desks and equipment rooms.

Frequently Asked Questions

The link does not come up — is the cable faulty?
Most often the transmit and receive fibres are crossed. Swap the two connectors at one end (A↔B), check the transceivers are the same type (SR vs LR), and try again.
Can I use OM4 with my existing OM3 cabling?
Yes, OM3, OM4 and OM5 are all 50/125 µm and mate with each other; the link performs to the level of the lowest grade in the path.
Which transceivers go with this cable?
Multimode 850 nm optics: for example 1000BASE-SX, 10GBASE-SR or 25GBASE-SR SFP modules, or 8/16/32G FC short-wave optics. Both ends must use the same standard.
Singular Expert Insight · Buyer's Guide
OM4 is the current standard for multimode SR links in racks and server rooms. Match three things before ordering: fibre type (OM4), connector at each end (LC / LC) and polish. Typical partners are switches with SFP/SFP+ ports and the matching transceivers.
✓ Buy it if your ports are LC on both sides and the link is OM4.
✕ Skip it if your transceivers are singlemode LR/LX — order OS2 instead.
→ Also consider the same cable in other lengths.
Not sure which fibre or connector you have? Send us the model of your switch, transceiver or patch panel and we will check it before you order.
