equip SC to LC Fibre Optic Patch Cable, OS2 Single-Mode 9/125µm, Duplex, LSZH, 2m, Yellow

The equip 254332 is a duplex OS2 single-mode fibre optic patch cable (9/125µm) with SC on one end and LC on the other, 2m long with an LSZH jacket. It is made for connecting switches, servers, media converters and fibre patch panels in building backbones, telecom rooms and long single-mode links.

The jacket follows the standard colour code (yellow for OS2), so the cord is easy to identify in a mixed rack. With SC at one end and LC at the other, it bridges SC equipment to LC ports directly, without an extra coupler in the path.

• 1× equip SC–LC OS2 duplex fibre patch cable, 2m
• Measurement protocol (test report), per manufacturer
• Transceivers, couplers and cleaning tools are not included

• OS2 single-mode fibre carries the 1310/1550 nm light used by single-mode optics (1000BASE-LX, 10GBASE-LR and similar). The same cord type serves short patches and long backbone links — reach is set by the transceivers and the whole link, not by this cord.
• SC is the larger square push-pull connector common on patch panels, media converters and telecom/FTTH equipment.
• 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.
• 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 2m, it suits patching between neighbouring rack units or adjacent racks.
• Each cable is supplied with a measurement protocol, per the manufacturer, so you have the measured values for your documentation.

• Multimode transceivers (SX, SR, 850 nm) or multimode panels — a single-mode cord will not give a reliable link with them.
• APC ports (green connectors, angled polish) — this is not an APC cord; mating non-APC and APC connectors damages the end faces and causes high loss.
• Ports with a different connector type — this cord has SC and LC only; for 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.
