EFB-Elektronik LC to LC Fibre Optic Patch Cable OM5 Multimode Duplex 50/125µm LSZH 3m Lime green

The EFB-Elektronik LC to LC patch cable is a 3 m duplex OM5 multimode fibre optic cord for linking two LC ports – typically a switch or server SFP port to a patch panel, media converter or another switch in the same rack or room.

OM5 is wideband 50/125 µm multimode fibre (lime green) designed for short-wave WDM and backwards compatible with OM3/OM4 optics. The jacket is halogen-free LSZH, so it is suitable for offices, comms rooms and other indoor spaces where low smoke and no halogen gases are preferred. Each cable ships with its own measurement protocol.

• 1 × EFB-Elektronik LC–LC OM5 duplex patch cable, 3 m
• 2 × duplex clips
• 1 × measurement protocol (test report)
• 1 × information sheet – supplied in a resealable polybag

• Both ends are LC – the small push-latch connector used on SFP, SFP+, SFP28 and duplex-LC QSFP transceivers and on most current patch panels.
• Duplex means two fibres – one transmits, one receives. If the link does not come up, the pair is usually crossed: swap the two connectors at one end.
• At 3 m the cable length is never the distance limit – the transceiver type is. Measure the real route including slack, and keep bends gentle (minimum bend radius static >10 × OD, dynamic >20 × OD).
• OM3, OM4 and OM5 are all 50/125 µm and can be patched together; the link then performs to the lowest grade in the path.

• Not for single-mode LR/LX optics – multimode and single-mode must not be mixed in one link.
• Not for RJ45 copper ports – a fibre link needs an SFP/SFP+ transceiver or a media converter at each end.
• It does not fit SC or ST ports – choose the cable with the matching connector at each end (or ask us).
• Avoid patching it into old OM1 62.5/125 µm cabling – the core mismatch causes high loss.
• Not for green APC (angled-polish) ports – APC and flat-polished connectors must never be mated.
