Equip SC to SC Fibre Optic Patch Cable OM3 Multimode Duplex 50/125µm LSZH 20m Aqua

The Equip 255328 is a 20 m SC-to-SC duplex fibre patch cable on laser-optimised OM3 multimode 50/125 µm fibre, built for linking switches, servers, storage and patch panels through short-reach multimode optics in server rooms, offices and data centres.

Both ends carry push-pull SC duplex connectors, and the aqua LSZH jacket follows the usual OM3 colour coding, which makes the link easy to recognise in a busy rack. Each cable ships with its own measurement protocol from the factory.

• 1 × Equip SC–SC duplex OM3 fibre patch cable, 20 m
• Individual test report (measurement protocol) for the cable

• Plug one duplex connector into a multimode SFP/SFP+ transceiver or patch panel port at each end — one fibre carries transmit, the other receive.
• At 20 m this cable suits links between rooms, across a floor or up a riser to another communications room.
• Per IEEE 802.3, 10GBASE-SR reaches up to 300 m on OM3 — far more than this cable's 20 m, so the cable length is never the limiting factor.
• If the link stays dark after plugging in, reverse the two fibres at one end (Tx/Rx swap) — every duplex fibre link needs transmit on one side to meet receive on the other.
• The LSZH jacket gives off little smoke and no halogen gases in a fire, which is why it is the usual choice for offices, public buildings and enclosed server rooms.

• Single-mode optics (OS2 9/125 µm, typically 1310/1550 nm LX/LR/ER modules) — use a single-mode patch cable for those.
• Copper RJ45 ports — the switch or NIC needs an SFP/SFP+ slot with a multimode fibre transceiver fitted.
• Ports with LC or ST connectors — you need a cable with the matching connector at that end.
• Outdoor, underground or direct-burial runs — this is an indoor patch cable.
