EFB-Elektronik LC to LC Fibre Optic Patch Cable OS2 Single-mode Duplex 9/125µm LSZH 10m Yellow

The EFB-Elektronik LC to LC patch cable is a 10 m duplex OS2 single-mode 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.

OS2 is 9/125 µm single-mode fibre (yellow) for long-reach 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 OS2 duplex patch cable, 10 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 10 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).
• Single-mode OS2 is what long-reach optics expect; the same cord works for a few metres in a rack or as the last patch of a building or campus link.

• Not for multimode SR/SX optics – single-mode and multimode 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).
• Not for green APC (angled-polish) ports – APC and flat-polished connectors must never be mated.
