equip LC to LC Fibre Optic Patch Cable, OM1 Multimode 62.5/125µm, Duplex, LSZH, 1m, Orange
equip LC–LC OM1 fibre optic patch cable, 1m
The equip 254421 is a duplex OM1 multimode fibre optic patch cable (62.5/125µm) 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 (orange for OM1), 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.
What's in the Box
- 1× equip LC–LC OM1 duplex fibre patch cable, 1m
- Measurement protocol (test report), per manufacturer
- Transceivers, couplers and cleaning tools are not included
What It Means in Practice
- 62.5/125µm OM1 is the legacy multimode grade found in older installations. Keep it on OM1 links: patching OM1 into a 50µm channel (OM2–OM5) creates a core mismatch and extra loss.
- 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.
- Each cable is supplied with a measurement protocol, per the manufacturer, so you have the measured values for your documentation.
What Will Not Work
- Single-mode transceivers or single-mode panels (LX, LR, OS1/OS2) — multimode cable cannot be used on single-mode links.
- Mixing with 50/125µm (OM2, OM3, OM4, OM5) cords, panels or optics specified for 50µm — the core sizes differ.
- 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.
