equip SC-SC Duplex Fibre Optic Patch Cable, OM3 multimode 50/125µm, LSZH, 5m, Aqua

The equip 255325 is a 5 m duplex OM3 multimode 50/125 µm fibre optic patch cable with SC connectors on both ends, for linking switches, servers, media converters and patch panels in racks and comms rooms.

OM3 is laser-optimised 50/125 µm multimode fibre, recognised by its aqua jacket, and the long-standing standard for 10 Gigabit links inside a building: IEEE specifies OM3 for 10GBASE-SR up to 300 m and 25GBASE-SR up to 70 m.

• 1 × SC-SC duplex fibre optic patch cable, 5 m (package contents as listed by the manufacturer)

• At 5 m it reaches between neighbouring racks or across a small comms room.
• Duplex means two fibres in one cable: one carries transmit and the other receive, so one cable completes one link between two transceivers.
• The LSZH (low smoke, zero halogen) jacket is the usual requirement in offices, data centres and public buildings: in a fire it gives off little smoke and no corrosive halogen gas.
• Keep the end faces covered until you plug in: a dirty connector is the most common reason a new fibre link does not come up.

• Single-mode optics (LX, LR, ER at 1310/1550 nm): they need an OS2 single-mode cable, not multimode.
• LC or ST ports, or a mix of connector types: this cable is SC on both ends.
• Copper RJ45 ports: fibre needs an optical transceiver or a media converter at each end.
• MPO/MTP ports (40G/100G SR4 parallel optics): they use multi-fibre trunk cables, not duplex patch cords.
