equip LC to LC Fibre Optic Patch Cable, OM4 Multimode 50/125µm, Duplex, LSZH, 1m, Violet

The equip 255511 is a duplex OM4 multimode fibre optic patch cable (50/125µm) with LC connectors on both ends, 1m long with an LSZH jacket. It is made for connecting switches, servers, media converters and fibre patch panels inside racks, server rooms and data centres over short multimode runs.

The jacket follows the standard colour code (violet for OM4), so the cord is easy to identify in a mixed rack. LC is the small push-latch connector used on SFP/SFP+ optics, on most current switch and server ports and on high-density patch panels.

• 1× equip LC–LC OM4 duplex fibre patch cable, 1m
• Transceivers, couplers and cleaning tools are not included

• 50/125µm multimode is driven by 850 nm short-reach optics (1000BASE-SX, 10GBASE-SR and similar). OM4 is the bandwidth grade; the reach of your link depends on the transceivers and the whole channel.
• The manufacturer rates it for 10G Ethernet up to 300 m and 40G Ethernet up to 150 m.
• Duplex means two fibres — one transmits, one receives. If a link does not come up, the usual cause is crossed polarity: reverse the two connectors at one end.
• The LSZH (low smoke, zero halogen) jacket is meant for indoor use where fire safety matters: in a fire it gives off less smoke and no corrosive halogen gases.
• At 1m, it suits patching inside one rack or between a panel and the switch directly below it.

• Single-mode transceivers or single-mode panels (LX, LR, OS1/OS2) — multimode cable cannot be used on single-mode links.
• Ports with a different connector type — this cord has LC on both ends only; for SC or ST ports you need a cable with those connectors.
• Copper RJ45 ports — fibre needs an optical transceiver or media converter at each end.
• Outdoor, underground or direct-burial runs — this is an indoor patch cable.
