Equip LC to LC Fibre Optic Patch Cable OM4 Multimode Duplex 50/125µm LSZH 7.5m Violet

The Equip 256515 is a 7.5 m LC-to-LC duplex fibre patch cable on laser-optimised OM4 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 small-form-factor LC duplex connectors, and the violet LSZH jacket follows the usual OM4 colour coding, which makes the link easy to recognise in a busy rack.

• 1 × Equip LC–LC duplex OM4 fibre patch cable, 7.5 m

• 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 7.5 m this cable suits links between racks in the same row or across a small server room.
• Equip rates this OM4 cable for 10G Ethernet up to 300 m and 40G up to 150 m, so the 7.5 m length leaves a very large margin.
• 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 SC 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.
